Does anyone know of any good sources for stepper motor tutorials? I've got a stepper motor here - 2-phase 4-wire dealio that I wanna get working and write some c0d3zzz for.
I haven't yet found a datasheet for it, but I did find some general specs for it. The part number is 57BHM76-280A-21BK and it comes up as a 0.9 degree per step, 3.2V @ 2.8A step motor. From what little I've been able to dig up I will need a dual H-bridge to drive it (one per phase) and I'm assuming the ECCP module of the PIC would be used to drive the H-bridge.
