 | | RE: newbie

NQC on the other hand, all it does is translate a NQC program into LEGO pCode that will be *interpreted* by (...) (23 years ago, 21-Jan-02, to lugnet.robotics.rcx.legos)

| Standard Lego firmware samples every 3 msec. BricOS is much faster. I believe it is faster than once per second. RobotC on NXT is programmable to be 0.5 msec scan, 1 msec, 2 msec, ... up to 255 msec. But remember the readings are not persistent. If (...) (18 years ago, 9-Sep-06, to lugnet.robotics.nxt)
