setting num channels to 512 with dmxOutput.write(workingBuffer, NUM_CHANNELS); where NUM_CHANNELS is 512, doesnt seem to send channel 512, but dmxOutput.write(workingBuffer, NUM_CHANNELS+1); does. small issue thanks Paul

Hi!

Take a look at the examples at the main page. You should add 1 to the number of channels you want to send to account for the start code of the DMX-frame. If you want to send a full-sized universe of 512 channels, the size of your working buffer should be 513, where the 0'th channel is your start code
