DMX arduino

has anyone tried receiving dmx data with the arduino board. what i'm trying to do is receive only one dmx value and control a servo with it. so fixed dmx address and just one value to interpret. i found the dmx master script but don't fully understand it to make my own version of it.

every help, startpoint is appreciated...

well receiving is a bit different than sending:)

you need to confgure the arduino serial port to handle the DMX speed 250Kbit/sec then wait for the break signal... start reading the values until you reach your address, store the vaue and ignore the rest

there is a pdf about receviing DMX with Avr processors here http://www.hoelscher-hi.de/hendrik/light/ressources/AN112.pdf

I have written a sketch to do this, instructions and download here: http://blog.wingedvictorydesign.com/2009/03/20/receive-dmx-512-with-an-arduino/

Let me know how it works for you!
