 ;D so i have a working code for 32 channel relay broad running on one of the megas
Code: You are not allowed to view links. Register or Login
const int numChannels = 32;
// List Arduino pins in Channel number order
int channels[numChannels] = {2,3,4,5,6,7,8,9,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45};
int incomingByte[numChannels];

void setup()
{
Serial.begin(9600);



for(int i = 0; i < numChannels; i++){
pinMode(channels[i], OUTPUT);
// Start with lights turned off
//digitalWrite(channels[i],0);
digitalWrite(channels[i],0);
}


}

void loop()
{
if (Serial.available() >= numChannels)
{
for (int i=0; i<numChannels;i++)
incomingByte[i] = Serial.read();


for(int i = 0; i < numChannels; i++)
//digitalWrite(channels[i], incomingByte[i]);
digitalWrite(channels[i], incomingByte[i]);
//LED STUFF

}
}

fastled test works fine. :)
but this code and vixen do radom things.
 what did i do wrong with the code?
Code: You are not allowed to view links. Register or Login

void setup() {

         FastLED.addLeds<WS2811, PIN, RGB>(leds, NUM_LEDS);
  Serial.begin(115200);

}

void loop() {

 
for(int i = 0; i < NUM_LEDS; i++) {
  if (Serial.available() > 2) {
    Serial.readBytes( (char*)leds, NUM_LEDS * 3);
   
  }
    FastLED.show();
 }

}

 ???
one of the main things it will do is start at light 2 for light 1, even though i made sure the controller points to the right spot

any help would be aprecited thanks

this coden works for pixels 1-21 then the rest are wierd

You would be better off posting this on an arduino forum.
