| | | | Could someone explain to me technically why this sort of of problem with the rotation sensor occurs? I know how quadrature shaft encoders are _supposed_ to work, and I can't see why this sort of thing should happen in the first place. >> Mark (21 years ago, 30-Nov-03, to lugnet.robotics, lugnet.robotics.rcx.robolab)

| | | | | | (...) The way I understand it, it's really not the sensor's fault. The RCX and firmware together either can't or doesn't deal with the ambiguous voltage levels sometimes returned during two of the four transitions. If the RCX were fast enough that (...)
