Project Intention:
Because RC5 isn't only outdated, today its already obsolete and because more and more electronic devices in consumer electronics around us are used, it is time to develop an IR-decoder that can 'understand' about 90 % of IR-remotes that are used in our daily life.

This article indroduces 'IRMP' as "Infrared-Multiprotocol-Decoder" in all details. The counterpart, [[IRSND_-_english|IRSND]] as IR-Encoder can be found in this [[IRSND_-_english|document]].

Each of these protocols can be activated separately. If you want, you can activate all protocols. If you need only one protocol, you can disable all others. It will only be compiled the code that has been selected by the user.

=== History ===

The [[IRMP_-_english#IRMP_-_Infrared_Multiprotocol_Decoder|IRMP]] source for the AVR- and PIC-µCs has been created as part of the [[Word Clock]] project.

=== Thread in Forum ===

Intention for an own IRMP article is the following thread in Projects&Code [http://www.mikrocontroller.net/topic/162119 IRMP - Infrared Multi Protocol Decoder] (in german language).

== IR Protocols ==

[[Datei:nec-protocol.png|miniatur|NEC protocol, RGB remote control, T->A: 9,14ms, A->B: 4,42ms, B->C: 660us]]

Some vendors use their own proprietary protocol, such as Sony, Samsung and Matsuhita. Philips has developed [[IRMP_-_english#RC5 + RC5X|RC5]] and of course used for own purposes.
[[IRMP_-_english#RC5 + RC5X|RC5]] was seen in Europe as ''that'' standard IR-protocol which was adopted by many european vendors. Nowadays is [[IRMP_-_english#RC5 + RC5X|RC5]] nearly nowhere used - it can be ticked as "dead". Although the successor [[IRMP_-_english#RC6_+_RC6A|RC6]] is used in actual european hardware, it is also used rarely.

Also japanese vendors tried to establish an own standard, the so called [[IRMP_-_english#KASEIKYO|Kaseikyo]]- (or also "Japan-") protocol. This is with a bitlength of 48 bits more versatile. But it has no general acceptance until today - even if you find it in some appliances.

Nowadays the [[IRMP_-_english#NEC_+_extended_NEC|NEC]] protocol is used (also mainly in japanese devices) - indeed in various premium and NoName products. I estimate the market share to 80 % for the [[IRMP_-_english#NEC_+_extended_NEC|NEC]]-protocol. Nearly all remotes in my daily use utilize the [[IRMP_-_english#NEC_+_extended_NEC|NEC]]-IR-Code. This starts at the TV-set, goes over the DVD-player to the Notebook remote and reaches up to NoName-Multimedaia-Harddrive, just to mention a few samples.

== Codings ==

[[IRMP_-_english#IRMP_-_Infrared_Multiprotocol_Decoder|IRMP]] supports the following IR-Codings:

* [[IRMP_-_english#Pulse Distance|Pulse Distance]], typ. Example: [[IRMP_-_english#NEC_+_extended_NEC|NEC]]
* [[IRMP_-_english#Pulse Width|Pulse Width]], typ. Example: [[IRMP_-_english#SIRCS|Sony SIRCS]]
* [[IRMP_-_english#Biphase|Biphase (Manchester)]], typ. Example: Philips [[IRMP_-_english#RC5_+_RC5X|RC5]], [[IRMP_-_english#RC6_+_RC6A|RC6]]
* [[IRMP_-_english#Pulse Position|Pulse Position (NRZ)]], typ. Example: [[IRMP_-_english#NETBOX|Netbox]]
* [[IRMP_-_english#Pulse Distance Width|Pulse Distance Width]], typ. Example: [[IRMP_-_english#NUBERT|Nubert]]

The pulses are modulated - usually with 36 kHz or 38 kHz - to reduce environment influences such as Indoorlightning or sunlight.

=== Pulse Distance ===

[[Datei:Pulse-Distance.png|miniatur|Pulse Distance Coding]]

A Pulse Distance Coding can be discovered by the following rule:

* there is only '''one pulse length''' and there are '''two different pause lengths'''

=== Pulse Width ===

[[Datei:Pulse-Width.png|miniatur|Pulse Width Coding]]

A Pulse Width Coding can be discovered by the following rule:

* there are '''two different pulse lengths''' and '''only one pause length'''

=== Pulse Distance Width ===

[[Datei:Pulse-Distance-Width.png|miniatur|Pulse Distance Width Coding]]

This is a mix from Pulse Distance and Pulse Width Coding, so:

* there are '''two different pulse lengths''' and '''two different pause lengths.'''

=== Biphase ===

[[Datei:Biphase-Coding.png|miniatur|Biphase Coding]]

In Biphase Coding the order of pulse and pause gives the bit value.
Therefore a Biphase-Coding can be discovered by this criteria:

* there is exactly '''one''' pause- and one pulse length, as well as the '''double''' pulse/pause length

Usually the length for the pulse and pause are equal, that means the signal shape is symmetric. But IRMP knows also protocols which use different puls/pause lengths. This case is for example the [[IRMP_-_english#A1TVBOX|A1TVBOX]]-protocol.

=== Pulse Position ===

[[Datei:Pulse-Position.png|miniatur|Pulse Position Coding]]

The pulse position coding is known from usual UART's. Every bit has a fixed length here. Depending on the value (0 or 1), it is a pulse or a pause.

Typical criteria for a '''pulse position protocol''' is:
* there are '''multiples''' of a basic pulse/pause length

'''A tabular listing of different IR-protocols can be found here: [[IRMP_-_english#IR_Protocols_in_Detail|IR Protocols in Detail]].'''
The specified timings are typical values. In some remotes they differ up to 40 % in real life. Therefore [[IRMP_-_english#IRMP_-_Infrared_Multiprotocol_Decoder|IRMP]] uses minimum/maximum limits to be tolerant with the timing.

== Protocol Detection ==

The most of the [[IRMP_-_english#IRMP_-_Infrared_Multiprotocol_Decoder|IRMP]] decoded protocols have something in common: they show a start bit which is unique for their timing.
According to this start bit timing the most protocols are discriminated. [[IRMP_-_english#IRMP_-_Infrared_Multiprotocol_Decoder|IRMP]] measures the timing of the start bit and reorders its timing tables "on-the-fly" for the discovered protocol. So the following bits can be read sequential without the need of storing a complete frame.
[[IRMP_-_english#IRMP_-_Infrared_Multiprotocol_Decoder|IRMP]] does not wait for reading a complete frame to analyze, it starts decoding after the first pulse detection.
If the first read start bit is not unique, [[IRMP_-_english#IRMP_-_Infrared_Multiprotocol_Decoder|IRMP]] follows multiple possible protocols. If for plausible reasons one protocol is no more possible this track will be dropped.

The detection is implemented as a [[Statemachine|state machine]], which is called interrupt driven with an frequency of typically 15.000 per second. the [[Statemachine|state machine]] knows the following states:

* detect the first pulse length of the start bit
* detect the pause length of the start bit
* detect the pulse length of the first data bit

After that, the pulse/pause length of the start bit are known. Now all enabled protocols are searched for this length. If a protocol matches, the timing table for this protocol is loaded and the following bits are checked if the pulse/pause timing still fit to the limis.

So the [[Statemachine|state machine]] continues with the following states:

* detect the pauses of the data bits
* detect the pulse length of the data bits
* check timing. If different, switch back to another valid IR protocol, otherwise return
* detect the sop bit if present in the protocol
* check data for plausibility, like CRC or other redundant data bits
* convert data to device address and command
* detect code repetition by long key press, set according flag

Indeed the [[Statemachine|state machine]] is even more complex because some protocols have no start bit (e.g. [[IRMP_-_english#DENON|Denon]]) or have multiple start bits (4 in [[IRMP_-_english#B.26O|B&O]]) or have within the frame another sync bit (z.B. [[IRMP_-_english#SAMSUNG|Samsung]]). These extra conditions are caught in the code by protocol specific "special cases".
Switching to an other protocol can happen multiple times during receiving of a frame, f.e. from [[IRMP_-_english#NEC42|NEC42]] (42 Bit) to [[IRMP_-_english#NEC16|NEC16]] (8 Bit + Sync-Bit + 8 Bit), when a premature sync bit was detected. Or from [[IRMP_-_english#NEC + extended NEC|NEC]]/[[IRMP_-_english#NEC42|NEC42]] (32/42 Bit) to [[IRMP_-_english#JVC|JVC]] (16 Bit) when the stop bit premature occured. It is getting difficult when two possible protocols after the detection of the start bit use different codings, e.g. when the one protocol uses a [[IRMP_-_english#Pulse Distance|Pulse Distance Coding]] and the other uses a [[IRMP_-_english#Biphase|Biphase Coding (Manchester)]]. In this case [[IRMP_-_english#IRMP_-_Infrared_Multiprotocol_Decoder|IRMP]] stores the necessary bits for both codings and releases later the one ore the other.

Furthermore some remotes are transmitting in particular protocols for redundance reasons (error detection) or for long key presses repetition frames. These will be discriminated by IRMP: the necessary frames for error detection are checked by IRMP, but not passed to the application. The other will be detected as long key press and flagged by IRMP.

Download of stable version: [http://www.mikrocontroller.net/wikifiles/7/79/Irmp.zip Irmp.zip]

[[IRMP_-_english#IRMP_-_Infrared_Multiprotocol_Decoder|IRMP]] & [[IRSND_-_english|IRSND]] is also available by SVN: [http://www.mikrocontroller.net/svnbrowser/irmp/ IRMP in SVN], Download [http://www.mikrocontroller.net/svnbrowser/irmp/?view=tar Tarball], Git: [https://github.com/svn2github/irmp IRMP on GitHub]

'''Warning:'''

The version in the SVN can be a newer version than the stable version stored in Irmp.zip. In doubt, use the download link of Irmp.zip.

'''You can see the history of the software changes here: [[IRMP_-_english#Software_History|Software History]]'''

== Source Code ==

The source code can be easily compiled for AVR-µCs by loading the project file irmp.aps in AVR Studio 4.

For other development environments it is simple to create a project or makefile. The source includes:

* [http://www.mikrocontroller.net/svnbrowser/irmp/irmp.c?view=markup irmp.c] - IR-decoder core
* [http://www.mikrocontroller.net/svnbrowser/irmp/irmpprotocols.h?view=markup irmpprotocols.h] - all protocoll definitions
* [http://www.mikrocontroller.net/svnbrowser/irmp/irmpsystem.h?view=markup irmpsystem.h] - target independant definitions for AVR/PIC/STM32
* [http://www.mikrocontroller.net/svnbrowser/irmp/irmp.h?view=markup irmp.h] - Include file for the application
* [http://www.mikrocontroller.net/svnbrowser/irmp/irmpconfig.h?view=markup irmpconfig.h] - user configuration

* [http://www.mikrocontroller.net/svnbrowser/irmp/main.c?view=markup main.c] - Sample application

{{Warnung|
;Important: include only irmp.h to your application:
<syntaxhighlight lang="c">
#include "irmp.h"
</syntaxhighlight>

All other include file are included within irmp.h. See also the sample application main.c.

Furthermore, the preprocessor constant '''F_CPU in project or makefile''' must be defined. This should have at least the value of 8000000UL, processor speed should be at least 8 MHz. This applies to AVR targets and not for CPU's with PLL.
}}

[[IRMP_-_english#IRMP_-_Infrared_Multiprotocol_Decoder|IRMP]] is also running on PIC processors. For the PIC-CCS compiler are already the necessary preprocessor defines set, so that [http://www.mikrocontroller.net/svnbrowser/irmp/irmp.c?view=markup irmp.c] can be directly used in the CCS environment. Only a short interrupt service routine like

<syntaxhighlight lang="c">
void TIMER2_isr(void)
{
irmp_ISR ();
}
</syntaxhighlight>

must be added. The Interrupt period time must be set to 66 µs (15 kHz).

For AVR processors you will find an example for the usage of [[IRMP_-_english#IRMP_-_Infrared_Multiprotocol_Decoder|IRMP]] in [http://www.mikrocontroller.net/svnbrowser/irmp/main.c?view=markup main.c]. The main things are the [[AVR-GCC-Tutorial/Die_Timer_und_Zähler_des_AVR|Timer]] initializing of the timer and the processing of received IR commands. The received protocoll, the device address and the command will be output on the HW-UART.

For the Stellaris LM4F120 Launchpad from TI (ARM Cortex M4) is a propriate timer init function already integrated in [http://www.mikrocontroller.net/svnbrowser/irmp/main.c?view=markup main.c].

[[IRMP_-_english#IRMP_-_Infrared_Multiprotocol_Decoder|IRMP]] can be used also with STM32 microcontrollers.

Another new implementation is available on the mbed platform.
=== avr-gcc Optimizations ===

From version avr-gcc 4.7.x the option [https://gcc.gnu.org/onlinedocs/gccint/LTO.html#LTO LTO-Option] can be used to make the call of the external function irmp_ISR() from the main ISR more efficent. This improves the performance of the ISR a little.

Add the following compiler- and linker options:

* additional compiler option: -flto
* additional linker options: -flto -Os

If you forget (under Windows?) the additional linker option -Os, the binary will be significant larger as it will no be optimized further. Also the option -flto must be passed to the linker, otherwise the link time optimization will not work.

=== Configuration ===

The configuration of [[IRMP_-_english#IRMP_-_Infrared_Multiprotocol_Decoder|IRMP]] is done by settings in [http://www.mikrocontroller.net/svnbrowser/irmp/irmpconfig.h?view=markup irmpconfig.h] :

* [[IRMP_-_english#F_INTERRUPTS|number of interrupts per second]]
* [[IRMP_-_english#IRMP_SUPPORT_xxx_PROTOCOL|supported IR protocols]]
* [[IRMP_-_english#IRMP_PORT_LETTER + IRMP_BIT_NUMBER|hardware pin for IR receiver]]
* [[IRMP_-_english#IRMP_LOGGING|IR logging]]

=== Adjustments in irmpconfig.h ===

[[IRMP_-_english#IRMP_-_Infrared_Multiprotocol_Decoder|IRMP]] will decode all protocols listed above in one ISR. For this, there are some settings necessary. These are set in [http://www.mikrocontroller.net/svnbrowser/irmp/irmpconfig.h?view=markup irmpconfig.h].

==== F_INTERRUPTS ====

Number of interrupts per second. Should be set to a value from 10000 to 20000. The higher the value, the better the resolution and therefore the quality of detection. But a higher interrupt rate means also higher CPU load. The value of 15000 is in most cases a good compromise.

Standardvalues:
<syntaxhighlight lang="c">
#define F_INTERRUPTS 15000 // interrupts per second
</syntaxhighlight>

On AVR controllers is a timer1 with 16 bit resolution used in the example [http://www.mikrocontroller.net/svnbrowser/irmp/main.c?view=markup main.c]. If for any reasons timer1 is not available, you can also use timer2 with 8 bit resolution.

In this case timer2 will be configured as:

<syntaxhighlight lang="c">
OCR2 = (uint8_t) ((F_CPU / F_INTERRUPTS) / 8) - 1 + 0.5); // Compare Register OCR2
TCCR2 = (1 << WGM21) | (1 << CS21); // CTC Mode, prescaler = 8
TIMSK = 1 << OCIE2; // enable timer2 interrupt
</syntaxhighlight>

The above example is valid for ATmega88/ATmega168/ATmega328. For other AVR-µC's check the datasheet.

You must not forget to adjust the ISR for timer2 as well:

<syntaxhighlight lang="c">
ISR(TIMER2_COMP_vect)
{
(void) irmp_ISR();
}
</syntaxhighlight>

==== IRMP_SUPPORT_xxx_PROTOCOL ====

Here you can select which protocols should be supported by [[IRMP_-_english#IRMP_-_Infrared_Multiprotocol_Decoder|IRMP]]. Standardprotocols are activated by default.
Would you like to turn on more protocols or turn off some other for memory saving reasons, then the corresponding values in [http://www.mikrocontroller.net/svnbrowser/irmp/irmpconfig.h?view=markup irmpconfig.h] must be set.

</syntaxhighlight>

Each [[IRMP_-_english#IRMP_-_Infrared_Multiprotocol_Decoder|IRMP]] supported IR protocoll consumes the noted amount of code. Here you can apply optimizations: for example the modulation frequency of 455 kHz for the [[IRMP_-_english#B&O|B&O]] protocol is far away from the frequencies that are used by other protocols. Maybe you need a different IR receiver, otherwise you could disable these protocols. For example you cannot receive a [[IRMP_-_english#B&O|B&O]]-protocol (455kHz) with a TSOP1738 / TSOP 31238.

Furthermore the protocols [[IRMP_-_english#SIEMENS_+_RUWIDO|SIEMENS]]/[[IRMP_-_english#FDC|FDC]]/[[IRMP_-_english#RCCAR|RCCAR]] are only reliable detected at a frequency starting at 15 kHz. For [[IRMP_-_english#LEGO|LEGO]] it is even 20 kHz. When you want to use these protocols, you must adjust [[IRMP_-_english#F_INTERRUPTS|F_INTERRUPTS]]. Otherwise, during compilation you will get a warning and the corresponding protocols are automatically disabled.

==== IRMP_PORT_LETTER + IRMP_BIT_NUMBER ====

This constant defines the pin where the IR receiver is connected.

Default value is PORT B6:
<syntaxhighlight lang="c">
/*---------------------------------------------------------------------------
* Change hardware pin here for ATMEL AVR
*---------------------------------------------------------------------------
*/
#if defined (ATMEL_AVR) // use PB6 as IR input on AVR
# define IRMP_PORT_LETTER B
# define IRMP_BIT_NUMBER 6
</syntaxhighlight>

These two values must match your hardware configuration.

This applies also to STM32 µC's:

<syntaxhighlight lang="c">
/*----------------------------------------------------------------------------
* Change hardware pin here for ARM STM32
*----------------------------------------------------------------------------
*/
#elif defined (ARM_STM32) // use C13 as IR input on STM32
# define IRMP_PORT_LETTER C
# define IRMP_BIT_NUMBER 13
</syntaxhighlight>

And the corresponding section for STM8 µC's:

<syntaxhighlight lang="c">
/*----------------------------------------------------------------------------
* Change hardware pin here for STM8
*----------------------------------------------------------------------------
*/
#elif defined (SDCC_STM8) // use PA1 as IR input on STM8
# define IRMP_PORT_LETTER A
# define IRMP_BIT_NUMBER 1
</syntaxhighlight>

For PIC controllers there is only the define for '''IRMP_PIN''' - depending on compiler:

<syntaxhighlight lang="c">
/*----------------------------------------------------------------------------
* Change hardware pin here for PIC C18 compiler
*----------------------------------------------------------------------------
*/
#elif defined (PIC_C18) // use RB4 as IR input on PIC
# define IRMP_PIN PORTBbits.RB4

/*----------------------------------------------------------------------------
* Change hardware pin here for PIC CCS compiler

==== IRMP_USE_CALLBACK ====

Default value:
<syntaxhighlight lang="c">
#define IRMP_USE_CALLBACK 0 // flag: 0 = don't use callbacks, 1 = use callbacks, default is 0
</syntaxhighlight>

When you turn on callbacks, on any level change at the input the callback function is called. This could be use to visualize incomming IR signals by driving another output pin.

Here is an example:

<syntaxhighlight lang="c">
#define LED_PORT PORTD // LED at PD6
#define LED_DDR DDRD
#define LED_PIN 6

/*-----------------------------------------------------------------------------------------------------------------------
* Called (back) from IRMP module
* This example switches a LED (which is connected to Vcc)
*-----------------------------------------------------------------------------------------------------------------------
*/
void
led_callback (uint8_t on)
{
if (on)
{
LED_PORT &= ~(1 << LED_PIN);
}
else
{
LED_PORT |= (1 << LED_PIN);
}
}

int
main ()
{
...
irmp_init ();

LED_DDR |= (1 << LED_PIN); // LED pin to output
LED_PORT |= (1 << LED_PIN); // switch LED off (active low)
irmp_set_callback_ptr (led_callback);

sei ();
...
}
</syntaxhighlight>

==== IRMP_LOGGING ====

With IRMP_LOGGING the logging of received IR frames can be turned on.

Default value:
<syntaxhighlight lang="c">
#define IRMP_LOGGING 0 // 1: log IR signal (scan), 0: do not. default is 0
</syntaxhighlight>

Further documentation can be found here: [[IRMP_-_english#Scanning_of_unknown_IR_Protocols|Scanning of unknown IR Protocols]].

=== IRMP in Practice ===

The [[IRMP_-_english#IRMP_-_Infrared_Multiprotocol_Decoder|IRMP]] supported protocols use partly variable, partly fixed bit length from 2 up to 48 bits. These will be described by preprocessor defines.

[[IRMP_-_english#IRMP_-_Infrared_Multiprotocol_Decoder|IRMP]] separates these IR frames always into 3 sections:

1. protocol ID
2. address or vendorcode
3. command

with this function

irmp_get_data (IRMP_DATA * irmp_data_p)

you can recall a decoded message. The return value is 1 when a message has been received, otherwise it is 0. In the first case the struct members

<syntaxhighlight lang="c">
irmp_data_p->protocol (8 Bit)
irmp_data_p->address (16 Bit)
irmp_data_p->command (16 Bit)
irmp_data_p->flags (8 Bit)
</syntaxhighlight>

contain valid information.

That means: finally you'll get simply three values (protocol, address and command) that can be checked with an if or switch statement.
Here is a sample decoder which checks for key 1-9 on a remote:

<syntaxhighlight lang="c">
IRMP_DATA irmp_data;

if (irmp_get_data (&irmp_data))
{
if (irmp_data.protocol == IRMP_NEC_PROTOCOL && // NEC-Protokoll
irmp_data.address == 0x1234) // Adresse 0x1234
{
switch (irmp_data.command)
{
case 0x0001: key1_pressed(); break; // Taste 1
case 0x0002: key2_pressed(); break; // Taste 2
...
case 0x0009: key9_pressed(); break; // Taste 9
}
}
}
</syntaxhighlight>

</syntaxhighlight>

The values of address and the command code of an unknown remote can be received and printed over UART or LCD. Then these values can be used hard coded in your decoder routine. Or you write a teaching routine, where you need to press a key once to store the code in an EEPROM. A sample for this can be found in [http://www.mikrocontroller.net/articles/DIY_Lernfähige_Fernbedienung_mit_IRMP Lernfähige IR-Fernbedienung mit IRMP].

Another [http://www.mikrocontroller.net/svnbrowser/irmp/main.c?view=markup Beispiel-Main-Funktion] is include in the zip file, showing also the timer initialization.

=== "Debouncing" of Keys ===

To distinguish between long key press or a single press, the bit IRMP_FLAG_REPETITION exists. This will be set in struct member '''flags''' when a key on the remote is pressed for longer time and therefor the same command is repeated in short periods.

Example:

<syntaxhighlight lang="c">
if (irmp_data.flags & IRMP_FLAG_REPETITION)
{
// long key press
// either:
// ignore the (repeated) key
// or:
// use this information for a repeat function
}
else
{
// key was pressed again
}
</syntaxhighlight>

This could be used to "debounce" the keys 0-9 by ignoring commands with bit IRMP_FLAG_REPETITION set. For keys like ' VOLUME+' or 'VOLUME-' using the repetition could be useful, maybe to fade a LED [[LED-Fading]fade a LED].

When you want to decode only singe keys, you can reduce the abov if block to:

<syntaxhighlight lang="c">
if (! (irmp_data.flags & IRMP_FLAG_REPETITION))
{
// Its a new key
// ACTION!
}
</syntaxhighlight>

== Mode of Operation ==

The "Working Horse" from [[IRMP_-_english#IRMP_-_Infrared_Multiprotocol_Decoder|IRMP]] is the interrupt service routine irmp_ISR() which should be called 15000 times per second. Is this rate different, the constant [[IRMP_-_english#F_INTERRUPTS|F_INTERRUPTS]] in [http://www.mikrocontroller.net/svnbrowser/irmp/irmpconfig.h?view=markup irmpconfig.h] needs to be adjusted.

irmp_ISR() detects first the length and the form of the startbit(s) and determines the used protocols by this information. As soon as the protocol was identified, the further bits are parameterized to read the following bits most efficient until the IR command is complete.

Just to stop slashers:

I know that the ISR is quite large. But as it acts as a state machine, the effective executed code per cycle is relative small. While it is "dark" (and that is the case for the most time ;-)) the spent time is vanishing short. In the WordClock project for example are called 8 ISR's with the same timer, there is irmp_ISR() only one amongst many others. For at least 8 MHz CPU clock no timing problems occured. Therefor I see really no problem in the length of the ISR.

A crystal is not a neccessary must, it works well with the internal AVR oscillator. Remember to set the correct fuses for the CPU to run at 8 MHz, check [http://www.mikrocontroller.net/svnbrowser/irmp/main.c?view=markup main.c] for correct values for an ATMEGA88.

== Scanning of unknown IR Protocols ==

Changing in [http://www.mikrocontroller.net/svnbrowser/irmp/irmpconfig.h?view=markup irmpconfig.h] in line

<syntaxhighlight lang="c">
#define IRMP_LOGGING 0 // 1: log IR signal (scan), 0: do not (default)
</syntaxhighlight>

the value for [[IRMP_-_english#IRMP_LOGGING|IRMP_LOGGING]] to 1, then in [[IRMP_-_english#IRMP_-_Infrared_Multiprotocol_Decoder|IRMP]] a logging will be turned on: the bright- and darkphases will be sent via UART with 9600 bit/s ausgegeben: 1=dark, 0=bright. Maybe the constans in the functions uart_init() and uart_putc() must be adjusted, this depends on the used AVR-µC.

'''Remark: for PIC-processors there is an own logging module named [http://www.mikrocontroller.net/svnbrowser/irmp/irmpextlog.c?view=markup irmpextlog.c]. This makes it possible to log via USB. This applies not to the AVR version'''

When you record these protocol scans with a terminal program and save it as a textfile, you can use these files for analyzing to adjust [[IRMP_-_english#IRMP_-_Infrared_Multiprotocol_Decoder|IRMP]] for the unknown protocol - see next chapter.

If you have a remote that is not supported by [[IRMP_-_english#IRMP_-_Infrared_Multiprotocol_Decoder|IRMP]] you can send me ([http://www.mikrocontroller.net/user/show/ukw ukw]) the scan files. Then I can check if the protocol fits into the IRMP concepts and adapt the sources if applicable.

== IRMP under Linux and Windows ==

=== Compilation ===

[http://www.mikrocontroller.net/svnbrowser/irmp/irmp.c?view=markup irmp.c] lässt sich auch unter Linux direkt kompilieren, um damit Infrarot-Scans, welche in Dateien gespeichert sind, direkt zu testen. Im Unterordner IR-Data finden sich solche Dateien, die man dem [[IRMP_-_english#IRMP_-_Infrared_Multiprotocol_Decoder|IRMP]] direkt zum "Fraß" vorwerfen kann.

Das Übersetzen von [[IRMP_-_english#IRMP_-_Infrared_Multiprotocol_Decoder|IRMP]] geht folgendermaßen:

make -f makefile.lnx

Dabei werden 3 IRMP-Versionen erzeugt:

* irmp-10kHz: Version für 10kHz Scans
* irmp-15kHz: Version für 15kHz Scans
* irmp-20kHz: Version für 20kHz Scans

=== Starting IRMP ===

Der Aufruf geschieht dann über:

./irmp-nnkHz [-l|-p|-a|-v] < scan-file

Die angegebenen Optionen schließen sich aus, das heisst, es kann jeweils nur eine Option zu einer Zeit angegeben werden:

Option:

-l List gibt eine Liste der Pulse und Pausen aus
-a analyze analysiert die Puls-/Pausen und schreibt ein "Spektrum" in ASCII-Form
-v verbose ausführliche Ausgabe
-p Print Timings gibt für alle Protokolle eine Timing-Tabelle aus

Hier sieht man die gemessenen Zeiten aller Pulse und Pausen als (liegende) Glockenkurven, welche natürlich wegen der ASCII-Darstellung nicht gerade einer Idealkurve entsprechen. Je schmaler die gemessenen Kanäle, desto besser ist das Timing der Fernbedienung.

Aus obigem Output kann man herauslesen:

* Das Start-Bit hat eine Pulslänge zwischen 9000 und 9200 usec, im Mittel sind es 9102 usec. Die Abweichung von diesem Mittelwert liegt bei 1,1 Prozent.

* Das Start-Bit hat eine Pausenlänge zwischen 4300 usec und 4500 usec, der Mittelwert beträgt 4424 usec. Der Fehler liegt bei 2,8 Prozent.

* Die Pulslänge eines Datenbits liegt zwischen 500 usec und 700 usec, im Mittel sind es 650 usec, der Fehler liegt bei (stolzen) 23,1 Prozent!

Desweiteren gibt es noch 2 verschieden lange Pausen (für die Bits 0 und 1), das Ablesen der Werte überlasse ich dem geneigten Leser ;-)

=== Starting under Windows ===

[[IRMP_-_english#IRMP_-_Infrared_Multiprotocol_Decoder|IRMP]] kann man auch unter Windows nutzen, nämlich folgendermaßen:

* Eingabeaufforderung starten
* In das Verzeichnis irmp wechseln
* Aufruf von:
irmp-10kHz.exe < IR-Data\rc5x.txt

Es gelten dieselben Optionen wie für die Linux-Version.

=== Long Outputs ===

Da manche Ausgaben sehr lang werden, empfiehlt es sich auch hier, die Ausgabe in eine Datei zu lenken oder in einen Pager weiterzuleiten, damit man seitenweise blättern kann:

== Cameras ==

[[Datei:Irmp-pentax.png|miniatur|Pentax-Protokoll]]

[[IRMP_-_english#IRMP_-_Infrared_Multiprotocol_Decoder|IRMP]] unterstützt zunehmend auch die Fernsteuerung von Kameras, nämlich:

* [[IRMP_-_english#PENTAX|PENTAX]]
* [[IRMP_-_english#NIKON|NIKON]]

Die Kommando-Vielfalt ist nicht gerade groß. Normalerweise verstehen die Kameras gerade mal das Kommando "Auslösen".

Hier eine kleine Tabelle für [[IRMP_-_english#PENTAX|PENTAX]]-Kameras:

{| {{Tabelle}}
|- style="background-color:#eeeeee"
! Kommando || Funktion
|-
| 0x0000 || Auslösen
|-
| 0x0001 || Zoomlevel umschalten
|-
|}

Da keine Adresse im [[IRMP_-_english#PENTAX|PENTAX]]-Protokoll vorgesehen ist, sollte man am diese beim Senden mittels [[IRSND_-_english|IRSND]] am besten auf 0x0000 setzen. Ebenso sollte man in diesem Fall einen Quarz verwenden, da gerade die Nikons bezüglich des Timings sehr penibel sind.

== IR Keyboards ==

[[Datei:irmp-fdc3402.jpg|miniatur|FDC-3402-Tastatur]]

[[IRMP_-_english#IRMP_-_Infrared_Multiprotocol_Decoder|IRMP]] unterstützt ab Version 1.7.0 auch IR-Tastaturen, nämlich die Infrarot-Tastatur FDC-3402 - erhältlich bei Pollin (Art. 711 056) für weniger als 2 EUR.

Beim Erkennen einer Taste gibt [[IRMP_-_english#IRMP_-_Infrared_Multiprotocol_Decoder|IRMP]] folgende Daten zurück:

Protokoll-Nummer (irmp_data.protocol): 18
Addresse (irmp_data.address): 0x003F

Als Kommando (irmp_data.command) werden folgende Werte zurückgeliefert:

Dabei gelten die obigen Werte für das Drücken einer Taste. Wird die Taste wieder losgelassen, setzt [[IRMP_-_english#IRMP_-_Infrared_Multiprotocol_Decoder|IRMP]] zusätzlich das 8. Bit im Kommando.

Beispiel:

Taste 'a' drücken: 0x001F
Taste 'a' loslassen: 0x009F

Ausnahme ist die EIN/AUS-Taste: Diese sendet nur beim Drücken einen Code, nicht beim Loslassen.

Wird eine Taste länger gedrückt, wird das in irmp_data.flag angezeigt.

Beispiel:

command flag
Taste 'a' drücken: 0x001F 0x00
Taste 'a' drücken: 0x001F 0x01
Taste 'a' drücken: 0x001F 0x01
Taste 'a' drücken: 0x001F 0x01
....
Taste 'a' loslassen: 0x009F 0x00

Werden Tastenkombinationen (zum Beispiel für ein großes 'A') gedrückt, dann sind die Rückgabewerte von [[IRMP_-_english#IRMP_-_Infrared_Multiprotocol_Decoder|IRMP]] in folgendem Ablauf zu sehen:

Linke SHIFT-Taste drücken: 0x0002
Taste 'a' drücken: 0x001F
Taste 'a' loslassen: 0x009F
Linke SHIFT-Taste loslassen: 0x0082

In [http://www.mikrocontroller.net/svnbrowser/irmp/irmp.c?view=markup irmp.c] findet man für die LINUX-Version eine Funktion get_fdc_key(), welche als Vorlage dienen mag, die Keycodes einer FDC-Tastatur in die entsprechenden ASCII-Codes umzuwandeln. Diese Funktion kann man entweder lokal auf dem µC nutzen, um die Keycodes zu decodieren, oder auf einem Hostsystem (z.B. PC), an welches die IRMP-Data-Struktur gesandt wird. Dafür sollte man die Funktion incl. der dazugehörenden Preprozessor-Konstanten in seinen Applikations-Quelltext kopieren.

else // it's a non-printable key

Die Funktion get_fdc_key berücksichtigt das Gedrückthalten der Shift-, Strg- und ALT-Tasten. Damit funktioniert nicht nur das Schreiben von Großbuchstaben, sondern auch das Auswählen der Sonderzeichen mit der Tastenkombination ALT + Taste, z.B. ALT + m = µ oder ALT + q = @. Ebenso kann man mit der Strg-Taste die Control-Zeichen CTRL-A bis CTRL-Z senden. Die CapsLock-Taste wird ignoriert, da ich sie sowieso für die überflüssigste Taste überhaupt halte ;-)

=== ACP24 Protocol ===

Das ACP24-Protokoll wird von Stiebel-Eltron-Klimaanlagen verwendet.

Die 70 Datenbits sind folgendermaßen aufgebaut:

1 2 3 4 5 6
0123456789012345678901234567890123456789012345678901234567890123456789

IRMP - english

2016-01-12T00:07:19Z

Jojos:

From '''Frank M. ([http://www.mikrocontroller.net/user/show/ukw ukw])'''

'''This will be the english translation of the [[IRMP_-_english#IRMP_-_Infrared_Multiprotocol_Decoder|IRMP]] documentation in the future.'''

'''This work is in progress yet.'''

[[Datei:irmp-title.png| |Scan eines NEC-kompatiblen Fernbedienungssignals]]

Project Intention:
Because RC5 isn't only outdated, today its already obsolete and because more and more electronic devices in consumer electronics around us are used, it is time to develop an IR-decoder that can 'understand' about 90 % of IR-remotes that are used in our daily life.

This article indroduces 'IRMP' as "Infrared-Multiprotocol-Decoder" in all details. The counterpart, [[IRSND_-_english|IRSND]] as IR-Encoder can be found in this [[IRSND_-_english|document]].

= IRMP - Infrared Multiprotocol Decoder =

[[Datei:irmp-empfaenger.png|miniatur|Connection of a IR receiver module to µC]]

=== Supported µCs ===

[[IRMP_-_english#IRMP_-_Infrared_Multiprotocol_Decoder|IRMP]] is already implemented on this AVR µCs:

* ATtiny87, ATtiny167
* ATtiny45, ATtiny85
* ATtiny44, ATtiny84
* ATmega8, ATmega16, ATmega32
* ATmega162
* ATmega164, ATmega324, ATmega644, ATmega644P, ATmega1284
* ATmega88, ATmega88P, ATmega168, ATmega168P, ATmega328P

Additionally, there is already a number of portings to various PIC microcontrollers - for CCS- and C18 compiler. IRMP is also adapted to AVR XMega, ARM STM32, STM8 ('''New!'''), ESP8266 ('''New!'''), TEENSY ('''New!'''), Stellaris LM4F120 Launchpad from TI (ARM Cortex M4) and the mbed platform('''New!''').

=== History ===

The [[IRMP_-_english#IRMP_-_Infrared_Multiprotocol_Decoder|IRMP]] source for the AVR- and PIC-µCs has been created as part of the [[Word Clock]] project.

=== Thread in Forum ===

Intention for an own IRMP article is the following thread in Projects&Code [http://www.mikrocontroller.net/topic/162119 IRMP - Infrared Multi Protocol Decoder] (in german language).

== IR Protocols ==

[[Datei:nec-protocol.png|miniatur|NEC protocol, RGB remote control, T->A: 9,14ms, A->B: 4,42ms, B->C: 660us]]

Some vendors use their own proprietary protocol, such as Sony, Samsung and Matsuhita. Philips has developed [[IRMP_-_english#RC5 + RC5X|RC5]] and of course used for own purposes.
[[IRMP_-_english#RC5 + RC5X|RC5]] was seen in Europe as ''that'' standard IR-protocol which was adopted by many european vendors. Nowadays is [[IRMP_-_english#RC5 + RC5X|RC5]] nearly nowhere used - it can be ticked as "dead". Although the successor [[IRMP_-_english#RC6_+_RC6A|RC6]] is used in actual european hardware, it is also used rarely.

Also japanese vendors tried to establish an own standard, the so called [[IRMP_-_english#KASEIKYO|Kaseikyo]]- (or also "Japan-") protocol. This is with a bitlength of 48 bits more versatile. But it has no general acceptance until today - even if you find it in some appliances.

Nowadays the [[IRMP_-_english#NEC_+_extended_NEC|NEC]] protocol is used (also mainly in japanese devices) - indeed in various premium and NoName products. I estimate the market share to 80 % for the [[IRMP_-_english#NEC_+_extended_NEC|NEC]]-protocol. Nearly all remotes in my daily use utilize the [[IRMP_-_english#NEC_+_extended_NEC|NEC]]-IR-Code. This starts at the TV-set, goes over the DVD-player to the Notebook remote and reaches up to NoName-Multimedaia-Harddrive, just to mention a few samples.

== Codings ==

[[IRMP_-_english#IRMP_-_Infrared_Multiprotocol_Decoder|IRMP]] supports the following IR-Codings:

* [[IRMP_-_english#Pulse Distance|Pulse Distance]], typ. Example: [[IRMP_-_english#NEC_+_extended_NEC|NEC]]
* [[IRMP_-_english#Pulse Width|Pulse Width]], typ. Example: [[IRMP_-_english#SIRCS|Sony SIRCS]]
* [[IRMP_-_english#Biphase|Biphase (Manchester)]], typ. Example: Philips [[IRMP_-_english#RC5_+_RC5X|RC5]], [[IRMP_-_english#RC6_+_RC6A|RC6]]
* [[IRMP_-_english#Pulse Position|Pulse Position (NRZ)]], typ. Example: [[IRMP_-_english#NETBOX|Netbox]]
* [[IRMP_-_english#Pulse Distance Width|Pulse Distance Width]], typ. Example: [[IRMP_-_english#NUBERT|Nubert]]

The pulses are modulated - usually with 36 kHz or 38 kHz - to reduce environment influences such as Indoorlightning or sunlight.

=== Pulse Distance ===

[[Datei:Pulse-Distance.png|miniatur|Pulse Distance Coding]]

A Pulse Distance Coding can be discovered by the following rule:

* there is only '''one pulse length''' and there are '''two different pause lengths'''

=== Pulse Width ===

[[Datei:Pulse-Width.png|miniatur|Pulse Width Coding]]

A Pulse Width Coding can be discovered by the following rule:

* there are '''two different pulse lengths''' and '''only one pause length'''

=== Pulse Distance Width ===

[[Datei:Pulse-Distance-Width.png|miniatur|Pulse Distance Width Coding]]

This is a mix from Pulse Distance and Pulse Width Coding, so:

* there are '''two different pulse lengths''' and '''two different pause lengths.'''

=== Biphase ===

[[Datei:Biphase-Coding.png|miniatur|Biphase Coding]]

In Biphase Coding the order of pulse and pause gives the bit value.
Therefore a Biphase-Coding can be discovered by this criteria:

* there is exactly '''one''' pause- and one pulse length, as well as the '''double''' pulse/pause length

Usually the length for the pulse and pause are equal, that means the signal shape is symmetric. But IRMP knows also protocols which use different puls/pause lengths. This case is for example the [[IRMP_-_english#A1TVBOX|A1TVBOX]]-protocol.

=== Pulse Position ===

[[Datei:Pulse-Position.png|miniatur|Pulse Position Coding]]

The pulse position coding is known from usual UART's. Every bit has a fixed length here. Depending on the value (0 or 1), it is a pulse or a pause.

Typical criteria for a '''pulse position protocol''' is:
* there are '''multiples''' of a basic pulse/pause length

'''A tabular listing of different IR-protocols can be found here: [[IRMP_-_english#IR_Protocols_in_Detail|IR Protocols in Detail]].'''
The specified timings are typical values. In some remotes they differ up to 40 % in real life. Therefore [[IRMP_-_english#IRMP_-_Infrared_Multiprotocol_Decoder|IRMP]] uses minimum/maximum limits to be tolerant with the timing.

== Protocol Detection ==

The most of the [[IRMP_-_english#IRMP_-_Infrared_Multiprotocol_Decoder|IRMP]] decoded protocols have something in common: they show a start bit which is unique for their timing.
According to this start bit timing the most protocols are discriminated. [[IRMP_-_english#IRMP_-_Infrared_Multiprotocol_Decoder|IRMP]] measures the timing of the start bit and reorders its timing tables "on-the-fly" for the discovered protocol. So the following bits can be read sequential without the need of storing a complete frame.
[[IRMP_-_english#IRMP_-_Infrared_Multiprotocol_Decoder|IRMP]] does not wait for reading a complete frame to analyze, it starts decoding after the first pulse detection.
If the first read start bit is not unique, [[IRMP_-_english#IRMP_-_Infrared_Multiprotocol_Decoder|IRMP]] follows multiple possible protocols. If for plausible reasons one protocol is no more possible this track will be dropped.

The detection is implemented as a [[Statemachine|state machine]], which is called interrupt driven with an frequency of typically 15.000 per second. the [[Statemachine|state machine]] knows the following states:

* detect the first pulse length of the start bit
* detect the pause length of the start bit
* detect the pulse length of the first data bit

After that, the pulse/pause length of the start bit are known. Now all enabled protocols are searched for this length. If a protocol matches, the timing table for this protocol is loaded and the following bits are checked if the pulse/pause timing still fit to the limis.

So the [[Statemachine|state machine]] continues with the following states:

* detect the pauses of the data bits
* detect the pulse length of the data bits
* check timing. If different, switch back to another valid IR protocol, otherwise return
* detect the sop bit if present in the protocol
* check data for plausibility, like CRC or other redundant data bits
* convert data to device address and command
* detect code repetition by long key press, set according flag

Indeed the [[Statemachine|state machine]] is even more complex because some protocols have no start bit (e.g. [[IRMP_-_english#DENON|Denon]]) or have multiple start bits (4 in [[IRMP_-_english#B.26O|B&O]]) or have within the frame another sync bit (z.B. [[IRMP_-_english#SAMSUNG|Samsung]]). These extra conditions are caught in the code by protocol specific "special cases".
Switching to an other protocol can happen multiple times during receiving of a frame, f.e. from [[IRMP_-_english#NEC42|NEC42]] (42 Bit) to [[IRMP_-_english#NEC16|NEC16]] (8 Bit + Sync-Bit + 8 Bit), when a premature sync bit was detected. Or from [[IRMP_-_english#NEC + extended NEC|NEC]]/[[IRMP_-_english#NEC42|NEC42]] (32/42 Bit) to [[IRMP_-_english#JVC|JVC]] (16 Bit) when the stop bit premature occured. It is getting difficult when two possible protocols after the detection of the start bit use different codings, e.g. when the one protocol uses a [[IRMP_-_english#Pulse Distance|Pulse Distance Coding]] and the other uses a [[IRMP_-_english#Biphase|Biphase Coding (Manchester)]]. In this case [[IRMP_-_english#IRMP_-_Infrared_Multiprotocol_Decoder|IRMP]] stores the necessary bits for both codings and releases later the one ore the other.

Furthermore some remotes are transmitting in particular protocols for redundance reasons (error detection) or for long key presses repetition frames. These will be discriminated by IRMP: the necessary frames for error detection are checked by IRMP, but not passed to the application. The other will be detected as long key press and flagged by IRMP.

'''You can see the history of the software changes here: [[IRMP_-_english#Software_History|Software History]]'''

== Source Code ==

The source code can be easily compiled for AVR-µCs by loading the project file irmp.aps in AVR Studio 4.

For other development environments it is simple to create a project or makefile. The source includes:

* [http://www.mikrocontroller.net/svnbrowser/irmp/irmp.c?view=markup irmp.c] - IR-decoder core
* [http://www.mikrocontroller.net/svnbrowser/irmp/irmpprotocols.h?view=markup irmpprotocols.h] - all protocoll definitions
* [http://www.mikrocontroller.net/svnbrowser/irmp/irmpsystem.h?view=markup irmpsystem.h] - target independant definitions for AVR/PIC/STM32
* [http://www.mikrocontroller.net/svnbrowser/irmp/irmp.h?view=markup irmp.h] - Include file for the application
* [http://www.mikrocontroller.net/svnbrowser/irmp/irmpconfig.h?view=markup irmpconfig.h] - user configuration

* [http://www.mikrocontroller.net/svnbrowser/irmp/main.c?view=markup main.c] - Sample application

{{Warnung|
;Important: include only irmp.h to your application:
<syntaxhighlight lang="c">
#include "irmp.h"
</syntaxhighlight>

All other include file are included within irmp.h. See also the sample application main.c.

Furthermore, the preprocessor constant '''F_CPU in project or makefile''' must be defined. This should have at least the value of 8000000UL, processor speed should be at least 8 MHz. This applies to AVR targets and not for CPU's with PLL.
}}

[[IRMP_-_english#IRMP_-_Infrared_Multiprotocol_Decoder|IRMP]] is also running on PIC processors. For the PIC-CCS compiler are already the necessary preprocessor defines set, so that [http://www.mikrocontroller.net/svnbrowser/irmp/irmp.c?view=markup irmp.c] can be directly used in the CCS environment. Only a short interrupt service routine like

<syntaxhighlight lang="c">
void TIMER2_isr(void)
{
irmp_ISR ();
}
</syntaxhighlight>

must be added. The Interrupt period time must be set to 66 µs (15 kHz).

For AVR processors you will find an example for the usage of [[IRMP_-_english#IRMP_-_Infrared_Multiprotocol_Decoder|IRMP]] in [http://www.mikrocontroller.net/svnbrowser/irmp/main.c?view=markup main.c]. The main things are the [[AVR-GCC-Tutorial/Die_Timer_und_Zähler_des_AVR|Timer]] initializing of the timer and the processing of received IR commands. The received protocoll, the device address and the command will be output on the HW-UART.

For the Stellaris LM4F120 Launchpad from TI (ARM Cortex M4) is a propriate timer init function already integrated in [http://www.mikrocontroller.net/svnbrowser/irmp/main.c?view=markup main.c].

[[IRMP_-_english#IRMP_-_Infrared_Multiprotocol_Decoder|IRMP]] can be used also with STM32 microcontrollers.

Another new implementation is available on the mbed platform.
=== avr-gcc Optimizations ===

From version avr-gcc 4.7.x the option [https://gcc.gnu.org/onlinedocs/gccint/LTO.html#LTO LTO-Option] can be used to make the call of the external function irmp_ISR() from the main ISR more efficent. This improves the performance of the ISR a little.

Add the following compiler- and linker options:

* additional compiler option: -flto
* additional linker options: -flto -Os

If you forget (under Windows?) the additional linker option -Os, the binary will be significant larger as it will no be optimized further. Also the option -flto must be passed to the linker, otherwise the link time optimization will not work.

=== Configuration ===

The configuration of [[IRMP_-_english#IRMP_-_Infrared_Multiprotocol_Decoder|IRMP]] is done by settings in [http://www.mikrocontroller.net/svnbrowser/irmp/irmpconfig.h?view=markup irmpconfig.h] :

* [[IRMP_-_english#F_INTERRUPTS|number of interrupts per second]]
* [[IRMP_-_english#IRMP_SUPPORT_xxx_PROTOCOL|supported IR protocols]]
* [[IRMP_-_english#IRMP_PORT_LETTER + IRMP_BIT_NUMBER|hardware pin for IR receiver]]
* [[IRMP_-_english#IRMP_LOGGING|IR logging]]

=== Adjustments in irmpconfig.h ===

[[IRMP_-_english#IRMP_-_Infrared_Multiprotocol_Decoder|IRMP]] will decode all protocols listed above in one ISR. For this, there are some settings necessary. These are set in [http://www.mikrocontroller.net/svnbrowser/irmp/irmpconfig.h?view=markup irmpconfig.h].

==== F_INTERRUPTS ====

Number of interrupts per second. Should be set to a value from 10000 to 20000. The higher the value, the better the resolution and therefore the quality of detection. But a higher interrupt rate means also higher CPU load. The value of 15000 is in most cases a good compromise.

Standardvalues:
<syntaxhighlight lang="c">
#define F_INTERRUPTS 15000 // interrupts per second
</syntaxhighlight>

On AVR controllers is a timer1 with 16 bit resolution used in the example [http://www.mikrocontroller.net/svnbrowser/irmp/main.c?view=markup main.c]. If for any reasons timer1 is not available, you can also use timer2 with 8 bit resolution.

In this case timer2 will be configured as:

<syntaxhighlight lang="c">
OCR2 = (uint8_t) ((F_CPU / F_INTERRUPTS) / 8) - 1 + 0.5); // Compare Register OCR2
TCCR2 = (1 << WGM21) | (1 << CS21); // CTC Mode, prescaler = 8
TIMSK = 1 << OCIE2; // enable timer2 interrupt
</syntaxhighlight>

The above example is valid for ATmega88/ATmega168/ATmega328. For other AVR-µC's check the datasheet.

You must not forget to adjust the ISR for timer2 as well:

<syntaxhighlight lang="c">
ISR(TIMER2_COMP_vect)
{
(void) irmp_ISR();
}
</syntaxhighlight>

==== IRMP_SUPPORT_xxx_PROTOCOL ====

Here you can select which protocols should be supported by [[IRMP_-_english#IRMP_-_Infrared_Multiprotocol_Decoder|IRMP]]. Standardprotocols are activated by default.
Would you like to turn on more protocols or turn off some other for memory saving reasons, then the corresponding values in [http://www.mikrocontroller.net/svnbrowser/irmp/irmpconfig.h?view=markup irmpconfig.h] must be set.

</syntaxhighlight>

Each [[IRMP_-_english#IRMP_-_Infrared_Multiprotocol_Decoder|IRMP]] supported IR protocoll consumes the noted amount of code. Here you can apply optimizations: for example the modulation frequency of 455 kHz for the [[IRMP_-_english#B&O|B&O]] protocol is far away from the frequencies that are used by other protocols. Maybe you need a different IR receiver, otherwise you could disable these protocols. For example you cannot receive a [[IRMP_-_english#B&O|B&O]]-protocol (455kHz) with a TSOP1738 / TSOP 31238.

Furthermore the protocols [[IRMP_-_english#SIEMENS_+_RUWIDO|SIEMENS]]/[[IRMP_-_english#FDC|FDC]]/[[IRMP_-_english#RCCAR|RCCAR]] are only reliable detected at a frequency starting at 15 kHz. For [[IRMP_-_english#LEGO|LEGO]] it is even 20 kHz. When you want to use these protocols, you must adjust [[IRMP_-_english#F_INTERRUPTS|F_INTERRUPTS]]. Otherwise, during compilation you will get a warning and the corresponding protocols are automatically disabled.

==== IRMP_PORT_LETTER + IRMP_BIT_NUMBER ====

This constant defines the pin where the IR receiver is connected.

Default value is PORT B6:
<syntaxhighlight lang="c">
/*---------------------------------------------------------------------------
* Change hardware pin here for ATMEL AVR
*---------------------------------------------------------------------------
*/
#if defined (ATMEL_AVR) // use PB6 as IR input on AVR
# define IRMP_PORT_LETTER B
# define IRMP_BIT_NUMBER 6
</syntaxhighlight>

These two values must match your hardware configuration.

This applies also to STM32 µC's:

<syntaxhighlight lang="c">
/*----------------------------------------------------------------------------
* Change hardware pin here for ARM STM32
*----------------------------------------------------------------------------
*/
#elif defined (ARM_STM32) // use C13 as IR input on STM32
# define IRMP_PORT_LETTER C
# define IRMP_BIT_NUMBER 13
</syntaxhighlight>

And the corresponding section for STM8 µC's:

<syntaxhighlight lang="c">
/*----------------------------------------------------------------------------
* Change hardware pin here for STM8
*----------------------------------------------------------------------------
*/
#elif defined (SDCC_STM8) // use PA1 as IR input on STM8
# define IRMP_PORT_LETTER A
# define IRMP_BIT_NUMBER 1
</syntaxhighlight>

For PIC controllers there is only the define for '''IRMP_PIN''' - depending on compiler:

<syntaxhighlight lang="c">
/*----------------------------------------------------------------------------
* Change hardware pin here for PIC C18 compiler
*----------------------------------------------------------------------------
*/
#elif defined (PIC_C18) // use RB4 as IR input on PIC
# define IRMP_PIN PORTBbits.RB4

/*----------------------------------------------------------------------------
* Change hardware pin here for PIC CCS compiler
*----------------------------------------------------------------------------
*/
#elif defined (PIC_CCS) // use PB4 as IR input on PIC
# define IRMP_PIN PIN_B4
</syntaxhighlight>

==== IRMP_USE_CALLBACK ====

Default value:
<syntaxhighlight lang="c">
#define IRMP_USE_CALLBACK 0 // flag: 0 = don't use callbacks, 1 = use callbacks, default is 0
</syntaxhighlight>

When you turn on callbacks, on any level change at the input the callback function is called. This could be use to visualize incomming IR signals by driving another output pin.

Here is an example:

<syntaxhighlight lang="c">
#define LED_PORT PORTD // LED at PD6
#define LED_DDR DDRD
#define LED_PIN 6

/*-----------------------------------------------------------------------------------------------------------------------
* Called (back) from IRMP module
* This example switches a LED (which is connected to Vcc)
*-----------------------------------------------------------------------------------------------------------------------
*/
void
led_callback (uint8_t on)
{
if (on)
{
LED_PORT &= ~(1 << LED_PIN);
}
else
{
LED_PORT |= (1 << LED_PIN);
}
}

int
main ()
{
...
irmp_init ();

LED_DDR |= (1 << LED_PIN); // LED pin to output
LED_PORT |= (1 << LED_PIN); // switch LED off (active low)
irmp_set_callback_ptr (led_callback);

sei ();
...
}
</syntaxhighlight>

==== IRMP_LOGGING ====

With IRMP_LOGGING the logging of received IR frames can be turned on.

Default value:
<syntaxhighlight lang="c">
#define IRMP_LOGGING 0 // 1: log IR signal (scan), 0: do not. default is 0
</syntaxhighlight>

Further documentation can be found here: [[IRMP_-_english#Scanning_of_unknown_IR_Protocols|Scanning of unknown IR Protocols]].

=== IRMP in Practice ===

The [[IRMP_-_english#IRMP_-_Infrared_Multiprotocol_Decoder|IRMP]] supported protocols use partly variable, partly fixed bit length from 2 up to 48 bits. These will be described by preprocessor defines.

[[IRMP_-_english#IRMP_-_Infrared_Multiprotocol_Decoder|IRMP]] separates these IR frames always into 3 sections:

1. protocol ID
2. address or vendorcode
3. command

with this function

irmp_get_data (IRMP_DATA * irmp_data_p)

you can recall a decoded message. The return value is 1 when a message has been received, otherwise it is 0. In the first case the struct members

<syntaxhighlight lang="c">
irmp_data_p->protocol (8 Bit)
irmp_data_p->address (16 Bit)
irmp_data_p->command (16 Bit)
irmp_data_p->flags (8 Bit)
</syntaxhighlight>

contain valid information.

That means: finally you'll get simply three values (protocol, address and command) that can be checked with an if or switch statement.
Here is a sample decoder which checks for key 1-9 on a remote:

<syntaxhighlight lang="c">
IRMP_DATA irmp_data;

if (irmp_get_data (&irmp_data))
{
if (irmp_data.protocol == IRMP_NEC_PROTOCOL && // NEC-Protokoll
irmp_data.address == 0x1234) // Adresse 0x1234
{
switch (irmp_data.command)
{
case 0x0001: key1_pressed(); break; // Taste 1
case 0x0002: key2_pressed(); break; // Taste 2
...
case 0x0009: key9_pressed(); break; // Taste 9
}
}
}
</syntaxhighlight>

Here are possible constants for irmp_data.protocol, see also [http://www.mikrocontroller.net/svnbrowser/irmp/irmpprotocols.h?view=markup irmpprotocols.h]:

</syntaxhighlight>

The values of address and the command code of an unknown remote can be received and printed over UART or LCD. Then these values can be used hard coded in your decoder routine. Or you write a teaching routine, where you need to press a key once to store the code in an EEPROM. A sample for this can be found in [http://www.mikrocontroller.net/articles/DIY_Lernfähige_Fernbedienung_mit_IRMP Lernfähige IR-Fernbedienung mit IRMP].

Another [http://www.mikrocontroller.net/svnbrowser/irmp/main.c?view=markup Beispiel-Main-Funktion] is include in the zip file, showing also the timer initialization.

=== "Debouncing" of Keys ===

To distinguish between long key press or a single press, the bit IRMP_FLAG_REPETITION exists. This will be set in struct member '''flags''' when a key on the remote is pressed for longer time and therefor the same command is repeated in short periods.

Example:

<syntaxhighlight lang="c">
if (irmp_data.flags & IRMP_FLAG_REPETITION)
{
// long key press
// either:
// ignore the (repeated) key
// or:
// use this information for a repeat function
}
else
{
// key was pressed again
}
</syntaxhighlight>

This could be used to "debounce" the keys 0-9 by ignoring commands with bit IRMP_FLAG_REPETITION set. For keys like ' VOLUME+' or 'VOLUME-' using the repetition could be useful, maybe to fade a LED [[LED-Fading]fade a LED].

When you want to decode only singe keys, you can reduce the abov if block to:

<syntaxhighlight lang="c">
if (! (irmp_data.flags & IRMP_FLAG_REPETITION))
{
// Its a new key
// ACTION!
}
</syntaxhighlight>

== Mode of Operation ==

The "Working Horse" from [[IRMP_-_english#IRMP_-_Infrared_Multiprotocol_Decoder|IRMP]] is the interrupt service routine irmp_ISR() which should be called 15000 times per second. Is this rate different, the constant [[IRMP_-_english#F_INTERRUPTS|F_INTERRUPTS]] in [http://www.mikrocontroller.net/svnbrowser/irmp/irmpconfig.h?view=markup irmpconfig.h] needs to be adjusted.

irmp_ISR() detects first the length and the form of the startbit(s) and determines the used protocols by this information. As soon as the protocol was identified, the further bits are parameterized to read the following bits most efficient until the IR command is complete.

Just to stop slashers:

I know that the ISR is quite large. But as it acts as a state machine, the effective executed code per cycle is relative small. While it is "dark" (and that is the case for the most time ;-)) the spent time is vanishing short. In the WordClock project for example are called 8 ISR's with the same timer, there is irmp_ISR() only one amongst many others. For at least 8 MHz CPU clock no timing problems occured. Therefor I see really no problem in the length of the ISR.

A crystal is not a neccessary must, it works well with the internal AVR oscillator. Remember to set the correct fuses for the CPU to run at 8 MHz, check [http://www.mikrocontroller.net/svnbrowser/irmp/main.c?view=markup main.c] for correct values for an ATMEGA88.

== Scanning of unknown IR Protocols ==

Stellt man in [http://www.mikrocontroller.net/svnbrowser/irmp/irmpconfig.h?view=markup irmpconfig.h] in der Zeile

<syntaxhighlight lang="c">
#define IRMP_LOGGING 0 // 1: log IR signal (scan), 0: do not (default)
</syntaxhighlight>

den Wert für [[IRMP_-_english#IRMP_LOGGING|IRMP_LOGGING]] auf 1, wird in [[IRMP_-_english#IRMP_-_Infrared_Multiprotocol_Decoder|IRMP]] eine Protokollierung eingeschaltet: Es werden dann die Hell- und Dunkelphase auf dem UART des Microntrollers mit 9600Bd ausgegeben: 1=Dunkel, 0=Hell. Eventuell müssen dann die Konstanten in den Funktionen uart_init() und uart_putc() angepasst werden; das kommt auf den verwendeten AVR-µC an.

Dieses ermöglicht das Logging über USB. Für AVR-Prozessoren ist [http://www.mikrocontroller.net/svnbrowser/irmp/irmpextlog.c?view=markup irmpextlog.c] irrelevant'''

Nimmt man diese Protokoll-Scans mit einem Terminal-Emulationsprogramm auf und speichert sie dann als normale Datei ab, kann man diese Scan-Dateien zur Analyse verwenden, um damit [[IRMP_-_english#IRMP_-_Infrared_Multiprotocol_Decoder|IRMP]] an das unbekannte Protokoll anzupassen - siehe nächstes Kapitel.

Wer eine Fernbedienung hat, die nicht von [[IRMP_-_english#IRMP_-_Infrared_Multiprotocol_Decoder|IRMP]] unterstützt wird, kann mir ([http://www.mikrocontroller.net/user/show/ukw ukw]) gern die Scan-Dateien zuschicken. Ich schaue dann, ob das Protokoll in das IRMP-Konzept passt und passe gegebenenfalls den Source an.

== IRMP under Linux and Windows ==

=== Compilation ===

[http://www.mikrocontroller.net/svnbrowser/irmp/irmp.c?view=markup irmp.c] lässt sich auch unter Linux direkt kompilieren, um damit Infrarot-Scans, welche in Dateien gespeichert sind, direkt zu testen. Im Unterordner IR-Data finden sich solche Dateien, die man dem [[IRMP_-_english#IRMP_-_Infrared_Multiprotocol_Decoder|IRMP]] direkt zum "Fraß" vorwerfen kann.

Das Übersetzen von [[IRMP_-_english#IRMP_-_Infrared_Multiprotocol_Decoder|IRMP]] geht folgendermaßen:

make -f makefile.lnx

Dabei werden 3 IRMP-Versionen erzeugt:

* irmp-10kHz: Version für 10kHz Scans
* irmp-15kHz: Version für 15kHz Scans
* irmp-20kHz: Version für 20kHz Scans

=== Starting IRMP ===

Der Aufruf geschieht dann über:

./irmp-nnkHz [-l|-p|-a|-v] < scan-file

Die angegebenen Optionen schließen sich aus, das heisst, es kann jeweils nur eine Option zu einer Zeit angegeben werden:

Option:

-l List gibt eine Liste der Pulse und Pausen aus
-a analyze analysiert die Puls-/Pausen und schreibt ein "Spektrum" in ASCII-Form
-v verbose ausführliche Ausgabe
-p Print Timings gibt für alle Protokolle eine Timing-Tabelle aus

Beispiele:

Hier sieht man die gemessenen Zeiten aller Pulse und Pausen als (liegende) Glockenkurven, welche natürlich wegen der ASCII-Darstellung nicht gerade einer Idealkurve entsprechen. Je schmaler die gemessenen Kanäle, desto besser ist das Timing der Fernbedienung.

Aus obigem Output kann man herauslesen:

* Das Start-Bit hat eine Pulslänge zwischen 9000 und 9200 usec, im Mittel sind es 9102 usec. Die Abweichung von diesem Mittelwert liegt bei 1,1 Prozent.

* Das Start-Bit hat eine Pausenlänge zwischen 4300 usec und 4500 usec, der Mittelwert beträgt 4424 usec. Der Fehler liegt bei 2,8 Prozent.

* Die Pulslänge eines Datenbits liegt zwischen 500 usec und 700 usec, im Mittel sind es 650 usec, der Fehler liegt bei (stolzen) 23,1 Prozent!

Desweiteren gibt es noch 2 verschieden lange Pausen (für die Bits 0 und 1), das Ablesen der Werte überlasse ich dem geneigten Leser ;-)

=== Starting under Windows ===

[[IRMP_-_english#IRMP_-_Infrared_Multiprotocol_Decoder|IRMP]] kann man auch unter Windows nutzen, nämlich folgendermaßen:

* Eingabeaufforderung starten
* In das Verzeichnis irmp wechseln
* Aufruf von:
irmp-10kHz.exe < IR-Data\rc5x.txt

Es gelten dieselben Optionen wie für die Linux-Version.

=== Long Outputs ===

Da manche Ausgaben sehr lang werden, empfiehlt es sich auch hier, die Ausgabe in eine Datei zu lenken oder in einen Pager weiterzuleiten, damit man seitenweise blättern kann:

Linux:

./irmp-10kHz < IR-Data/rc5x.txt | less

Windows:

== Cameras ==

[[Datei:Irmp-pentax.png|miniatur|Pentax-Protokoll]]

[[IRMP_-_english#IRMP_-_Infrared_Multiprotocol_Decoder|IRMP]] unterstützt zunehmend auch die Fernsteuerung von Kameras, nämlich:

* [[IRMP_-_english#PENTAX|PENTAX]]
* [[IRMP_-_english#NIKON|NIKON]]

Die Kommando-Vielfalt ist nicht gerade groß. Normalerweise verstehen die Kameras gerade mal das Kommando "Auslösen".

Hier eine kleine Tabelle für [[IRMP_-_english#PENTAX|PENTAX]]-Kameras:

{| {{Tabelle}}
|- style="background-color:#eeeeee"
! Kommando || Funktion
|-
| 0x0000 || Auslösen
|-
| 0x0001 || Zoomlevel umschalten
|-
|}

Da keine Adresse im [[IRMP_-_english#PENTAX|PENTAX]]-Protokoll vorgesehen ist, sollte man am diese beim Senden mittels [[IRSND_-_english|IRSND]] am besten auf 0x0000 setzen. Ebenso sollte man in diesem Fall einen Quarz verwenden, da gerade die Nikons bezüglich des Timings sehr penibel sind.

== IR Keyboards ==

[[Datei:irmp-fdc3402.jpg|miniatur|FDC-3402-Tastatur]]

[[IRMP_-_english#IRMP_-_Infrared_Multiprotocol_Decoder|IRMP]] unterstützt ab Version 1.7.0 auch IR-Tastaturen, nämlich die Infrarot-Tastatur FDC-3402 - erhältlich bei Pollin (Art. 711 056) für weniger als 2 EUR.

Beim Erkennen einer Taste gibt [[IRMP_-_english#IRMP_-_Infrared_Multiprotocol_Decoder|IRMP]] folgende Daten zurück:

Protokoll-Nummer (irmp_data.protocol): 18
Addresse (irmp_data.address): 0x003F

Als Kommando (irmp_data.command) werden folgende Werte zurückgeliefert:

Dabei gelten die obigen Werte für das Drücken einer Taste. Wird die Taste wieder losgelassen, setzt [[IRMP_-_english#IRMP_-_Infrared_Multiprotocol_Decoder|IRMP]] zusätzlich das 8. Bit im Kommando.

Beispiel:

Taste 'a' drücken: 0x001F
Taste 'a' loslassen: 0x009F

Ausnahme ist die EIN/AUS-Taste: Diese sendet nur beim Drücken einen Code, nicht beim Loslassen.

Wird eine Taste länger gedrückt, wird das in irmp_data.flag angezeigt.

Beispiel:

command flag
Taste 'a' drücken: 0x001F 0x00
Taste 'a' drücken: 0x001F 0x01
Taste 'a' drücken: 0x001F 0x01
Taste 'a' drücken: 0x001F 0x01
....
Taste 'a' loslassen: 0x009F 0x00

Werden Tastenkombinationen (zum Beispiel für ein großes 'A') gedrückt, dann sind die Rückgabewerte von [[IRMP_-_english#IRMP_-_Infrared_Multiprotocol_Decoder|IRMP]] in folgendem Ablauf zu sehen:

Linke SHIFT-Taste drücken: 0x0002
Taste 'a' drücken: 0x001F
Taste 'a' loslassen: 0x009F
Linke SHIFT-Taste loslassen: 0x0082

In [http://www.mikrocontroller.net/svnbrowser/irmp/irmp.c?view=markup irmp.c] findet man für die LINUX-Version eine Funktion get_fdc_key(), welche als Vorlage dienen mag, die Keycodes einer FDC-Tastatur in die entsprechenden ASCII-Codes umzuwandeln. Diese Funktion kann man entweder lokal auf dem µC nutzen, um die Keycodes zu decodieren, oder auf einem Hostsystem (z.B. PC), an welches die IRMP-Data-Struktur gesandt wird. Dafür sollte man die Funktion incl. der dazugehörenden Preprozessor-Konstanten in seinen Applikations-Quelltext kopieren.

Als letztes noch ein Beispiel einer Anwendung der Funktion get_fdc_key():

<syntaxhighlight lang="c">
if (irmp_get_data (&irmp_data))

uint8_t key;

if (irmp_data.protocol == IRMP_FDC_PROTOCOL &&
(key = get_fdc_key (irmp_data.command)) != 0)

}
else // it's a non-printable key
{
printf ("ascii-code = 0x%02x\n", key);
}
}
}
</syntaxhighlight>

Alle nicht-druckbaren Zeichen werden dabei folgendermaßen codiert:

Die Funktion get_fdc_key berücksichtigt das Gedrückthalten der Shift-, Strg- und ALT-Tasten. Damit funktioniert nicht nur das Schreiben von Großbuchstaben, sondern auch das Auswählen der Sonderzeichen mit der Tastenkombination ALT + Taste, z.B. ALT + m = µ oder ALT + q = @. Ebenso kann man mit der Strg-Taste die Control-Zeichen CTRL-A bis CTRL-Z senden. Die CapsLock-Taste wird ignoriert, da ich sie sowieso für die überflüssigste Taste überhaupt halte ;-)

=== ACP24 Protocol ===

Das ACP24-Protokoll wird von Stiebel-Eltron-Klimaanlagen verwendet.

Die 70 Datenbits sind folgendermaßen aufgebaut:

1 2 3 4 5 6
0123456789012345678901234567890123456789012345678901234567890123456789

Diese werden in die folgenden 16 Bits von irmp_data.command gewandelt:

5432109876543210
NAVVvMMMmtxyTTTT

Bedeutung der Symbole:

TTTT = Temperatur + 15 Grad

== Danksagung ==

Ganz herzlich bedanken möchte ich mich bei Vlad Tepesch, Klaus Leidinger und Peter K., die mich mit Scan-Dateien ihrer Infrarot-Fernbedienungen versorgt haben. Dank auch an Klaus für seine nächtelangen Tests von [[IRMP_-_english#IRMP_-_Infrared_Multiprotocol_Decoder|IRMP]] & [[IRSND_-_english|IRSND]].

Ebenso bedanken möchte ich mich bei Christian F. für seine Tipps zur PIC-Portierung. Vielen Dank auch an gera für die Portierung auf den PIC-C18 Compiler. Für die Portierung auf ARM STM32 bedanke ich mich herzlich bei kichi (Michael K.). Vielen Dank auch an Markus Schuster für die Portierung auf Stellaris LM4F120 Launchpad von TI (ARM Cortex M4). Danke an Matthias Frank für die Portierung auf XMega. Vielen Dank auch an Wolfgang S. für die Portierung auf ESP8266, Achill Hasler für die Portierung auf Teensy. Und zuletzt noch Dank an Axel Schwenke für den Port auf STM8.

Mein Dank geht auch an Dániel Körmendi, welcher mich nicht nur immer wieder fleißig mit Scans versorgt, sondern auch das LG-AIR-Protokoll in den [[IRSND_-_english|IRSND]] eingebaut hat. Danke auch hier an Ulrich v.d. Kammer für die [[IRSND_-_english|IRSND]]-Variante des Pentax-Protokolls.
