(...) Because of the way BrickOS uses interrupts to handle active sensors, it's possible for sensors to be deprived of power for 300us or more, though typically the interval is only 30us or so. This is due to long interrupt latencies in BrickOS that (...) (20 years ago, 25-Feb-04, to lugnet.robotics.rcx.legos)

Hi, I instrumented Steve Hassenplug's legway code so that after it falls over it can dump sensor data and motor control valiables out to a PC.
