Version 3.1.2, Date: 2018-09-06
Download of stable version: Irsnd.zip
IRMP & IRSND is also available by SVN: IRMP in SVN
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 Irsnd.zip.
You can see the history of the software changes here: Software History
Source Code
The source code can be easily compiled for AVR MCUs by loading the project file irsnd.aps in AVR Studio 4.
For other development environments it is simple to create a project or makefile. The source includes:
- irsnd.c - the IR encoder
- irmpprotocols.h - defintions of IR protocols
- irmpsystem.h - system dependent definitions for AVR/PIC/STM32
- irsnd.h - include file for application
- irsndconfig.h - configuration file
- irsnd-main-avr.c - example main
IMPORTANT:
You should only include irsnd.h in your application file, therefore merely:
#include "irsnd.h"
All other include files will be automatically included by irsnd.h. See also example file irsnd-main-avr.c.
IRSND encodes all protocols listed above in an interrupt service routine (ISR), see also irsnd.c.
Adjustments in irsndconfig.h
F_INTERRUPTS
Number of interrupts per second. The value can be adjusted between 10000 and 20000.
Default value:
#define F_INTERRUPTS 15000 // interrupts per second
IRSND_SUPPORT_xxx_PROTOCOL
Here you can adjust, which protocols of IRSND will be supported. The standard protocols are already activated. If you want to activate more protocols respectively you want to deactivate some protocols in order to same Flash and RAM, you should change the appropriate values in irsndconfig.h.

If you want to deactivate a protocol, set it to 0, if you want to activate it, set it to 1. All deactivated protocols will NOT be compiled. This saves Flash and RAM, siehe the specifications in comments above. If you want to save more Flash, you can also follow the tipps given in the article of IRMP.
If you want to use the APPLE protocol, set IRSND_SUPPORT_NEC_PROTOCOL to 1. It is only a special case of the NEC protocol.
IRSND_OCx
In order to send the correct IR signals, IRSND need a PWM-able Output-Pin, because the signal needs to be modulated. Following settings are possible:
#define IRSND_OCx IRSND_OC2 // OC2 on ATmegas supporting OC2, e.g. ATmega8
#define IRSND_OCx IRSND_OC2A // OC2A on ATmegas supporting OC2A, e.g. ATmega88
#define IRSND_OCx IRSND_OC2B // OC2B on ATmegas supporting OC2B, e.g. ATmega88
#define IRSND_OCx IRSND_OC0 // OC0 on ATmegas supporting OC0, e.g. ATmega162
#define IRSND_OCx IRSND_OC0A // OC0A on ATmegas/ATtinys supporting OC0A, e.g. ATtiny84, ATtiny85
#define IRSND_OCx IRSND_OC0B // OC0B on ATmegas/ATtinys supporting OC0B, e.g. ATtiny84, ATtiny85
Default value:
#define IRSND_OCx IRSND_OC2B
For PIC and STM32 MCUs use the appropriate values, see comments in irsndconfig.h.
IRSND_USE_CALLBACK
Default value:
#define IRSND_USE_CALLBACK 0 // flag: 0 = don't use callbacks, 1 = use callbacks, default is 0
If you use callbacks, your callback functions will be called, whenever the IR signal changes (IR modulation on/off). This can by used to send an unmodulated signal by another pin, for example:
#define LED_PORT PORTD // LED at PD6
#define LED_DDR DDRD
#define LED_PIN 6
/*-----------------------------------------------------------------------------------------------------------------------
* Called (back) from IRSND 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 ()
{
...
LED_DDR |= (1 << LED_PIN); // LED pin to output
LED_PORT |= (1 << LED_PIN); // switch LED off (active low)
irsnd_init ();
irsnd_set_callback_ptr (led_callback);
sei ();
...
}
IRSND in Practice
IRSND builds the frame to be sended "on-the-fly" from the IRMP data structure. The members are:
1. ID for used protocol 2. Address repectivley vendor code 3. Command
You can send the IR frame by calling the function
irsnd_send_data (IRMP_DATA * irmp_data_p)
The return value is 1, if the frame can be successfully sent out, otherwise 0. In the first case the struct members
irmp_data_p->protocol
irmp_data_p->address
irmp_data_p->command
irmp_data_p->flags
will be interpreted and then send out with the wanted IR protocol frame.
irmp_data_p->flags specifies the number of repetitions, e.g.
irmp_data_p->flags = 0: no repetition irmp_data_p->flags = 1: 1 repetition irmp_data_p->flags = 2: 2 repetitions usw.
Please consider: You should always make sure that irmp_data_p->flags has a defined value before you call irsnd_send_data()!
Example:
IRMP_DATA irmp_data;
irmp_data.protocol = IRMP_NEC_PROTOCOL; // use NEC protocol
irmp_data.address = 0x00FF; // use address 0x00FF
irmp_data.command = 0x0001; // use command 0001
irmp_data.flags = 0; // no repetition!
(void) irsnd_send_data (&irmp_data, FALSE); // send, don't wait
The frrame will be sent asynchronisly via the interrupt routine irsnd_ISR(), so that the funtion irsnd_send_data() immediately returns. If you specify repetitions, the frame will be repeated after a while - according to the used protocol - or a special protocol dependent repetition frame (e.g. for NEC) will be sent.
If you call irsnd_send_data() again, thhe functions waits until the preceding frame will be sent completely. You can also check if IRSND is "busy" or not:
while (irsnd_is_busy ())
{
; // wait here or do something else...
}
(void) irsnd_send_data (&irmp_data, FALSE); // versende ohne Prüfung und ohne Warten
If you call irsnd_send_data() with the 2nd argument TRUE, the function returns, when the frame has been completely sent.
In the example source irsnd-main-avr.c you will find beside the calling of irsnd_send_data() also the timer call:
ISR(TIMER1_COMPA_vect)
{
irsnd_ISR()) // call irsnd ISR
// call other timer interrupt routines...
}
Parallel use of IRMP und IRSND
If you want to use IRMP and IRSND together (that is to say as sender and receiver), you should write the ISR function as follows:
ISR(TIMER1_COMPA_vect)
{
if (! irsnd_ISR()) // call irsnd ISR
{ // if not busy...
irmp_ISR(); // call irmp ISR
}
// call other timer interrupt routines...
}
That means: Only when irsnd_ISR() has nothing to do, call the ISR of the receiver. Thereby the receiver is switched off, as long as irsnd_ISR() sends data. The timer initializing routine is identical for IRMP and IRSND.
A common main function could look as:
int
main (void)
{
IRMP_DATA irmp_data;
irmp_init(); // initialize irmp
irsnd_init(); // initialize irsnd
timer_init(); // initialize timer
sei (); // enable interrupts
for (;;)
{
if (irmp_get_data (&irmp_data))
{
irmp_data.flags = 0; // reset flags!
irsnd_send_data (&irmp_data);
}
}
}
The functionality of the source above is clear: A received frame will be encoded and sent again after decoding. So you can send signals over more than one rooms connected by wire.
Also you could transform some protocols, e.g. NEC frames into RC5, when you can't find your original RC5 remote control ;-)
All other stuff can be surrended by your phantasy ;-)

IRSND under Linux and Windows
Compilation of IRSND
You can compile irsnd.c directly unter Linux in order to create frames in the same format as the IRMP scan files. Simply enter:
make -f makefile.unx
Start of IRSND
The usage of IRSND is as follows:
./irsnd protocol-number hex-address hex-command [repeat] > filename.txt
Example for NEC protocol, address 0x00FF, command 0x0001:
./irsnd 2 00FF 0001 > nec.txt # start irsnd
IRSND under Windows
You can also use IRSND under Windows:
- Start the command interpreter
- Change into the directory of IRSND
- Enter:
irsnd.exe 2 00FF 0001 > nec.txt
Now you can directly test IRMP to check, if the generated frame by IRSND can be decoded again:
./irmp-15kHz < nec.txt
respectively under Windows:
irmp.exe < nec.txt
It works also without a temporary file, e.g.:
./irsnd-15kHz 2 00FF 0001 | ./irmp-15kHz
respectively under Windows:
irsnd.exe 2 00FF 0001 | irmp.exe
The output of IRMP is then as follows:
11111111000000001000000001111111 p = 2, a = 0x00ff, c = 0x0001, f = 0x00
So, IRMP could IRSND identify the frame generated by IRSND as protocol number 2, address 0x00FF and command 0x0001.
Actual IRSND under Linux/Windows simulates always the pressing of a key done twice - with a pause time between the frames. The output is therefore:
11111111000000001000000001111111 p = 2, a = 0x00ff, c = 0x0001, f = 0x00
11111111000000001000000001111111 p = 2, a = 0x00ff, c = 0x0001, f = 0x00
The reason is simple: Here you can test, if IRSND handles the toggle bit used by some protocols correctly:
./irsnd-15kHz 7 2 3 0 | ./irmp-15kHz
1100010000011 p= 7 (RC5), a=0x0002, c=0x0003, f=0x00 Erster Tastendruck
1000010000011 p= 7 (RC5), a=0x0002, c=0x0003, f=0x00 Zweiter Tastendruck
^
Toggle-Bit
Please consider: The data width of addresses and commands are different - dependent from the used protocol, see table IR Protocols in Detail.
Therefore you cannot send 16 bit addresses or commands with every protocol transparently.
