摘要步进电机是一种数字电机，它受脉冲信号控制，并将脉冲信号变成对应的角位移或者线位移。为了实现更高性能的控制，以单片机为核心的步进电机控制系统将得到更普遍的应用。本设计是以PHILIPS单片32位ARM微控制器－LPC2134为核心器件的步进电机控制系统,它以L297和L298作为步进电机的驱动器，通过软件编程实现步进电机的各项功能：通过按键输入，用LED灯显示步进电机启动停止、正反转、加减速这些状态，并用数码管显示转速的大小。75956
ARM单片机已经被广泛应用于工业控制和生产生活方面,此系统相对于传统单片机控制系统，具有外围接口数量多，处理速度快，精度较高等特点。并且它可以在提高精度的同时降低生产成本，是步进电机控制系统改善和提高的一条有效途径。

Design of stepping motor control system based on ARM single chip microcomputer
Abstract The stepping motor is a kind of digital motor, which is controlled by the pulse signal, and the electric pulse signal is converted into the corresponding angular displacement or line displacement。 In order to achieve a higher performance of the control, microcontroller as the core of the stepper motor control system will be more widely used。 This design is to Philips single-chip 32-bit arm micro controller LPC2134 as the core component of the stepper motor control system, it L297+L298 combination as a stepper motor drive, through software programming realizes step into the function of the motor: through the key input, with LED lights display stepper motor starting and stopping, in positive and negative acceleration and deceleration of the state, and use of digital tube display speed of the size。
ARM has been widely used in industrial control and production and life, the system relative to the traditional single-chip microcomputer control system, with rich peripheral interface resources, a fast processing speed, high precision。 And it can improve the precision and reduce the production cost, and it is an effective way to improve and improve the control system of the stepper motor。
