FASTLED and DmxReceiver.h

[stephanschulz]

i am trying to use DmxReceiver.h and FastLed library together but get this error:


In file included from teensy_dmx_serial.ino:7:0:
/Users/pankow/Documents/Arduino1/libraries/FastLED/FastLED.h:21:2: error: 'DMX' redeclared as different kind of symbol
teensy_dmx_serial:5: error: previous declaration of 'DmxReceiver DMX'

is there a way around this?

thanks,
stephan.

//this works fine for teensy


#include <DmxReceiver.h>
DmxReceiver DMX = DmxReceiver();

#include "FastLED.h"

//#define USE_SERIAL

//int boardLED = 13;
boolean boardLED_state = true;


//---------------------------------------DMX-------------------------------------

#define NUM_LEDS 15

// Data pin that led data will be written out over

// Clock pin only needed for SPI based chipsets when not using hardware SPI

// This is an array of leds.  One item for each led in your strip.

boolean led_vcc_on = false;

void setup(void) {

  pinMode(led_vcc_switchPin, OUTPUT);
  digitalWrite(led_vcc_switchPin, LOW);
  led_vcc_on = false;

  //DMX.begin();
#ifdef USE_SERIAL
  Serial.begin(115200);
#endif

  FastLED.addLeds<WS2801, DATA_PIN, CLOCK_PIN, RGB>(leds, NUM_LEDS);

}

void loop(){

#ifdef USE_SERIAL
  if (Serial.available()){
    handleInput(Serial.read());
  }
#endif

  if(led_vcc_on == false){
    if(millis() > 2000){
      led_vcc_on = true;
      digitalWrite(led_vcc_switchPin, HIGH);
      // digitalWrite(ledPin, LOW);
    }
  }


  DMX.bufferService();

  if (DMX.newFrame()) {
    for(int i=0; i<DMX_NUM_CHANNELS; i++){
      dmx_data[i] = dmx_getDimmer(i+1);
      //fadeValues[i] = dmx_data[i] 
    }
    for(int i = 0; i < NUM_LEDS; i++) {
      leds[i].setRGB( dmx_data[i], 0,0);
    }
    FastLED.show();
  }

}

Fast LED.h declares DMX as an enumeration constant:

enum EClocklessChipsets {
	DMX,
	TM1809,
	TM1804,
	TM1803,
	WS2811,
	WS2812,
	WS2812B,
	WS2811_400,
	NEOPIXEL,
	UCS1903
};

So in your code, you need to change DMX to be another name as a global variable, and in all of the places that refer to it.

Yeah - I need to go through and move everything into a namespace to scale back on collisions like that.

You could also change this:

DmxReceiver DMX = DmxReceiver();

to something like this:

DmxReceiver myDMX = DmxReceiver();

and then simple replace all the "DMX" name with "myDMX" in that example program. Yes, a bit of extra work, but not difficult.

thanks that worked.
