Abstract: During the operation of the stepper motor, the electronic pulse signal from the single-chip microcomputer can control its rotation angle, and with the help of the single-chip hardware circuit and software programming form,the stepper motor can be started, stopped, and forward and reverse Action to achieve effective control of the stepper motor. Based on this, this article analyzes the stepper motor control based on the single-chip microcomputer to provide a reference for the application and control of the stepper motor.
