// 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 = 11;

// the setup routine runs once when you press reset:
void setup() {             
  Serial.begin(38400);
  // 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 ) {
