I though that the four "Timer()" values read out in 100ms increments only.
Is there a way to get a 1ms timer with NQC?

| (...) You are right, the timer values as seen by the firmware are in 1/10ths of a second. I lost myself in H8-land, which has a 1 ms timer that gets divided down before being seen by the firmware. -Kekoa (26 years ago, 25-Apr-99, to lugnet.robotics)
