In order to achieve the control of stepping motor and detection for phase current of stepping motor, the control and detection system of the motor is designed and implemented by adopting Cortex-M3 as the main controller, and the dedicated driving chip L298N for controlling and driving the stepping motor. The phase current of the motor is acquired by the system through current conversion chip MAX4172, while the functions of frequency setting of the stepping motor and data display are conducted via RS-232 serial communication with the host computer. The overall system features good performance, stable operation, simple structure, low cost, easy to control and detect the stepping motor, and possesses excellent practical applicable values.
