Jeff did some work trying to do just what you describe, and it worked OK some of the time. Other times there would be 400 ms (yes, millisecond) latencies. His goal was just to use he Beagleboard as the motion controller, with an FPGA doing the base thread stuff. It wasn't even suitable for that using the -rt kernel. - Steve ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
