I am using Bipolar stepper motor Haydon Kerk 25343-05. My driver IC is DRV8833. The micro controller I am using is ATXMEGA16A4U.
The bipolar stepper motor has 4 wires. 4 PWM output pins of Microcontroller go to the driver chip which in-turn drives the stepper motor.
The step angle of the motor is 7.5 degree. If I name the wires as A,B,C,D; what kind of input pattern should be given to drive the motor forward. Should I give delay after each step, If so, how much delay should I give?
