It does not seem to be a natively supported feature so I was wondering if anyone had an idea how to add DMX control to Firmata. On the http://firmata.org/wiki/Download (at the bottom) there is a DMX Firmware listed, I believe the same one that is listed here http://forum.arduino.cc/index.php?topic=39333.0 but I can not get it to work. I am not sure how to trigger the commands.
I was thinking it would look something like, you could assign a pin on the arduino board to a dmx channel, or something like that. I have tried but Firmata is still over my head and I am not sure how to add libraries to it. Thanks
