To all, but specially to Roman Black.

I found this list by looking for a "stepper motor controller"  and I am
also beginning with pic micro chips.

I read the spec's about "Roman Blacks Linistepper stepper motor
controller". It makes use of power transistors in the output stage. It
was readings somewhere that they are running hot.

Question:
Is it not possible to put 4 pwm devices in the place of the end
transistors. These PWM devises could be 4 pics with a PWM output and a
MOSFET. This may be simplistic, but ........

Is there somebody that has done this? Or is this to difficult to do? How
would you do it.

Thanks,

Willy
