Greetings, I'm looking at an under-hood stepper motor interface application, however I don't know the full specs of the system yet. In particular, I'm assuming there are 2 basic approaches one invlovling the micro provide the actual stepper pulses, and another where a dedicated chip recieves commands from the micro, and off-loads the micro of the step pulses.
Can someone point me to a good stable source for such stepper interface chips, and perhaps tell me a little about their experience with them?
TIA,
