Re: RobotC and Eclipse ADK
Yeah, it is pretty easy. I used intellij at the time because it was less buggy. They probably have worked out the problems with eclipse by now. but the adk is the same.http://www.spiked3.com/?p=253
Actually, thinking about it, I didn't do anything on the NXT side - I use LCP, aka direct commands. If you need to actually have code run on the NXT side you can use bluetooth serial, or XBees (see other articles on my site).
I do not know of a way to read serial from the USB connection though. You can read sensors, run motors, even read encoders without any code on the NXT side, although it is slower than if you had code running on the NXT.
