Hi all,

I'm currenlty using a Microcontroller chip PIC18F4520 which is connected to ULN2003A and the stepper motor is sanyo denki 103H546 - 0440 Unipolar Stepper motor. I have the MPLAB C18 C Compiler for programming purposes.

Does anyone have a simple code so i can drive the motor for microstepping purposes as i am pretty confuse on the how to implement pwm to move the motor in microstep

Thanks
