stepper motor interfacing to 8051

用TA8435设计步进电机的资料,有原理图,PCB图片.-Stepper motor with the TA8435 design information has schematics, PCB picture.

This is simple ASM code to rotate stepper motor in clockwise motion. You have to attach ULN2003 IC to microcontroller and output of ULN2003 should be attached to Stepper motor. I tested this code with four coil stepper motor. You can create HEX file
