Dear all, I have an almost certain idea that someone out there has built a PIC based stepper motor controller (step/dir or ABCD) with acceleration and deceleration, maybe even with RS232 commands? I would really like to get my hands on some source code (c/asm), can anyone help me ? Kent -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
