Hi Ralph, It looks like TIMER 0 is hosed in v1.05. Take a gander at this: ----- : time RCX_INIT 0 0 TIMER_SET 32 0 DO 0 TIMER_GET .

Hi Ralph, Are timer_SET and timer_GET working? I can't seem to get any non-zero values from them: RCX_INIT ok 0 FFFF timer_SET ok 0 timer_GET . 0 ok Am I missing something? Thanks, Jonathan (25 years ago, 27-Jul-99, to lugnet.robotics.rcx.pbforth)

The Mindstorms RCX Code software does the exact same thing as the code you listed, the only caveat is I think RCX Code uses power settings from 1 to 8 while NQC uses 0 to 7. Both result in the same bytecodes for the RCX to interpret. // turn A on (...) (25 years ago, 23-Jul-99, to lugnet.robotics.rcx.nqc)

The RCX uses pulse-width modulation to control power to the motor. The pulses are between 1ms and 8ms of power during an 8ms interval. In theory, this would result in different power being provided to the motor. The problem is that the motor has an (...) (25 years ago, 22-Jul-99, to lugnet.robotics.rcx.nqc)

I think that output power effects the modulation of the motor power. The motor power cycles on and off with the off time being longer at lower power settings.

I've had the same result. It seems an **unloaded** motor always runs at full speed. To explain it to myself, I've theorized that the 'p' (power) in Fwd() and OutputPower() is more akin to force and does not directly control velocity. Waiting for (...)
