摘　　要：本文设计了基于本公司自主研发的CMC520MD32单片机开发步进电机驱控系统:其中系统控制部分负责接收DMX512通信协议并且根据梯形加减速原理解析命令生成驱动电机的脉冲和方向信号。同时,系统驱动部分基于正弦脉宽调制算法实现步进电机多级细分技术。This paper designs a stepping motor drive control system based on the CMC520 MD32 microcontroller independently developed by the company: the system control part is responsible for receiving the DMX512 communication protocol and analyzing commands based on the trapezoidal acceleration and deceleration principle to generate the pulse and direction signals of the drive motorl. At the same time, the system driving part is based on the sinusoidal pulse width modulation algorithm to realize the stepping motor multi-level subdivision technology.
