Stepper Motors using the 68HC12 - Jackie Johnson - Mar 25 12:52:00 2004

I have enclosed a program that I a working on and am trying to get this
program to work properly. My motor is not stopping. Example: If I
want my motor to stop at 90 degrees with a 1.2498 voltage applied via
the POT (potentiometer). My motor is continually running and not
stopping based on my POT adjustments. Any ideas would be greatly
appreciated from a frustrated student, who is on Spring break and NOT in
Mexico!

I have enclosed my program (MINIIDE) for your perusal. I want to
operate in the half-step mode.

THANKS,
Jackie
