I also looked at the archive at Iversoft but my search did nothing as well. What I need to do is control a bi-polar stepper motor, fwd and rvs. Does anybody know of information (tutorial, code examples,...etc) or has any info that would be willing to share with me. I will be using the ST ( and ALLEGRO) 6219 stepper motor driver with a PIC16F874-20/P. Any help/advice would be greatly appreciated. Thanks alot!!
