Abstract
At least an output shaft angle associated with an output shaft is initialized to a known value where the output shaft is coupled to a motor shaft via a set of one or more gears. A direction of rotation associated with the motor shaft is determined using a plurality of discrete Hall sensors in the motor and the output shaft angle is updated using an incremental value and the direction of rotation.
