Hi to all...
I'm trying to done a pwm to stepper converter for ms1 cpu, and i want to replicate (if possible) the ms2 driver circuitery... But i've a question:
All the enable pins are connected together, and there are 2 phases, that in every combination leave applied current to both 2 coils.
So i assume that the stepper is always doing half steps...
Right?
Thanks for any help...
