I thought I have a problem with SD21 servo controller, but after testing that with Mega1280 and Romeo All-in-one, problem was solved:http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1295678346
No problem with Sd21.
What is the trick to make I2C communication to work, two Duemilanove's have been tested with the same problem. They just don't find anything from any address.
This is annoying, I've been googling for two days, and no answers found so far.
It's time to relax with my kid today, maybe tomorrow is better with this mc.
Thanks in advance, great forum!
