// CTC-DRA-13-1 ISOLATED DMX-RDM SHIELD JUMPER INSTRUCTIONS

//

// If you are using the above mentioned shield you should 

// place the RXEN jumper towards G (Ground), This will turn

// the shield into read mode without using up an IO pin

//

// The !EN Jumper should be either placed in the G (GROUND) 

// position to enable the shield circuitry 

//   OR

// if one of the pins is selected the selected pin should be

// set to OUTPUT mode and set to LOGIC LOW in order for the 

// shield to work

//

//

// The slave device will use a block of 10 channels counting from

// its start address.

//

// If the start address is for example 56, then the channels kept

// by the dmx_slave object is channel 56-66

//

#define DMX_SLAVE_CHANNELS   10 

//

// Pin number to change read or write mode on the shield

// Uncomment the following line if you choose to control 

// read and write via a pin

//

// On the CTC-DRA-13-1 shield this will always be pin 2,

// if you are using other shields you should look it up 

// yourself

//

///// #define RXEN_PIN                2

// Configure a DMX slave controller

DMX_Slave dmx_slave ( DMX_SLAVE_CHANNELS );

// If you are using an IO pin to control the shields RXEN

// the use the following line instead

///// DMX_Slave dmx_slave ( DMX_SLAVE_CHANNELS , RXEN_PIN );

const int ledPin = 13;

// the setup routine runs once when you press reset:

void setup() {             

  // Enable DMX slave interface and start recording

  // DMX data

  dmx_slave.enable ();  

  // Set start address to 1, this is also the default setting

  // You can change this address at any time during the program

  dmx_slave.setStartAddress (1);

  // Set led pin as output pin

  pinMode ( ledPin, OUTPUT );

}

// the loop routine runs over and over again forever:

void loop() 

{

  //

  // EXAMPLE DESCRIPTION

  //

  // If the first channel comes above 50% the led will switch on

  // and below 50% the led will be turned off

  // NOTE:

  // getChannelValue is relative to the configured startaddress

  if ( dmx_slave.getChannelValue (1) > 127 )

    digitalWrite ( ledPin, HIGH );

  else

    digitalWrite ( ledPin, LOW );
