Currently, I'm trying to do microstepping with a 68hc12. I know how to put a step motor runing with full step, etc etc.... but I can't do microstepping Can anyone please explain me how to use the pwm to control the step of the motor??? Thanks in advance |

The 45 deg points both coils are on at .707, at the 90 deg points one coil is +, the other -, etc. [Non-text portions of this message have been removed] |
