I am hoping to control some stepper motors with the Handy Board; I will be
wanting to control position vs time. Therefore I will be wanting to send
out the step control waveforms at varying times (to modulate velocity).
Can this be done from Interactive C? I am quite familiar with assembler
language on the 6811, and the various timers on board.
This seems similar to software-generated PWM, for which we use Output Compare.
Anyway, any suggestions? Thanks.
