hey...
please help me, i have a problem with my system. I use at89s51 microcontroller for control the stepper motor. I use RS232 connection to the PC server. I want to control stepper motor for half-step rotation according from my command. I use hyperterminal for the input.My assembly program (downloaded to microcontroller) is recognized 2 character: L for turn left and R for turn right and it's just for 1 step. My problem is : I can't control the motor stepper for 1 step only (for half-step), I can do that just for full-step....please helr me about the assembly program :cry:
