With the demoPgm I can’t fine a way to set the DMX start code in the frame. It’s always 0.
Is there a trick to set it, or is there some other test code that lets me set ALL parts of a frame and send it?
If you use the source of the demo program, you will see a variable called StartAddress.
This is what I use in Delphi for starting my device.
StartDevice;
StartAddress:=1;
SetChannelCount(512);
