Now that I have brought up that topic, anyone know how to drive a stepper motor w/ RCX
PWM?

----- End of forwarded message from Wes Matchett -----

Generaly you'll need to convert the PWM to whatever sort of input the
appropriate stepper motor controller chip uses. Most of them will have a
for/rev/stop/brake along with a stepping speed select.

It's important to remember that steppers break by energizing (or shorting)
all the drive coils in the stepper.

I'd suggest select your motor, then select the appropriate controller chip.
Then you'll have the data to actualy design the convertor.

Good luck.
