I usually set up my BrickOS programs so they use the internal timer, and only update the motor setting (...) (19 years ago, 17-Sep-05, to lugnet.robotics.rcx.nqc)

| This was a terrific analysis. It's not surprizing that current implementation hogs so much CPU time. If all four A/D channels are scanned every 150 us then the A/D interrupt is occuring every 37.5 us since each A/D channel generates its own (...)
