(...) have you tried making your own PWM speed setting in NQC? 5 X = ?? Y = ?? 10 ? CLR 20 motor A ON 30 wait x 40 motor A OFF 50 wait Y 60 goto 20 Man I wish NQC was that easy. either way you get the idea. you can PWM the RCX yourself and control (...)

(...) Cool to know. (...) Then you need another bank of sensors, perhaps, to tell you when a train is coming "near" the siding, for instance. Cruise speed until near a siding, then slow speed to approach siding, and finally "creeping" speed to (...) (19 years ago, 14-Oct-05, to lugnet.org.ca.rtltoronto)

(...) sorry Brian, I stand by my original statement, I WISH "C" was as easy to grok as BASIC. My understanding from Dave, was that he was just looking for a way to slow an unloaded car down. Either way, software exists to "roll your own" PWM. as to (...) (19 years ago, 14-Oct-05, to lugnet.org.ca.rtltoronto)

(...) Well, you couldn't translate the DCC routines to NQC (if that's what you're asking) because the byte code interpreter used by NQC is simply too slow to generate the correct waveform (by a factor of about 1000!)
