(...) I don't know how NQC drives the ports, but both rcxcc and the RIS software have separate controls for on/off and power level. I just tested setting all 8 power settings - motors operates for all 8. -Wes (26 years ago, 26-Mar-99, to lugnet.robotics)

Right. That is why you cannot use all 8 power levels. The polarity reversal that I am talking about is on the controlling (and only) output. I am already assuming, at this point, that drive power is stuck on as with your external battery box. (...) (26 years ago, 26-Mar-99, to lugnet.robotics)

(...) Are you sure? I wasn't, so I went looking. The NQC docs seem to imply 7 powers levels plus off. Which, technically, is 8 levels of PWM, but if you use all of them, a motor is running at all times. That is fine if you use another motor output (...) (26 years ago, 26-Mar-99, to lugnet.robotics)

In my example the RCX output was just used to tell this mythical board which output to drive. Power for the output came from a battery box, always set to on. The RCX can't set direction on the battery box (at least not trivially). alex (...) -- Did (...) (26 years ago, 26-Mar-99, to lugnet.robotics)
