A system and method for determining a microstep rotor offset of a stepper motor is provided. The system includes a microcontroller configured to control voltage applied to a first coil and a second coil provided to operate the stepper motor; a back electro-magnetic force (BEMF) detection circuit configured to detect BEMF generated from the stepper motor. The stepper motor drives a pointer with a pointer stop, and the system is configured to: 1) home the stepper motor to the pointer stop, and 2) perform an iterative operation to determine a specific microstep associated with the microstep rotor offset.
