说明：   此源代码,是一个一种基于MCU的电机控制系统，单片机SCM接收PC的信息，根据Modbus通信协议转换为相应电机控制制命令。 整个程序源码在keil环境下开发，实现了电机的启动、停止、增速、减速、反馈运行时间与速度的功能。。
(This source code is a motor control system based on the MCU, the MCU SCM receives PC, according to the Modbus communication protocol is converted to the corresponding motor control commands. Keil environment, the entire program source code development, motor start, stop, growth rate, deceleration, the feedback running time and speed of function. .)
