本程序是基于单片机的步进电机控制程序，与东芝公司的TB6560步进电机驱动芯片配合控制步进电机。主要功能是单片机通过串口接受到相应的步进电机控制命令，然后控制TB6560驱动步进电机执行相应的动作，主要命令有：正转、反转、启动、停止、转速设定、转动角度设定等。-This procedure is based on the chip stepper motor control program, with Toshiba' s TB6560 stepper motor control with stepper motor driver chip. Main function is to receive the corresponding microcontroller through the serial stepper motor control commands, and then drive a stepper motor control TB6560 appropriate action, the main commands: forward, reverse, start, stop, speed setting, set the rotation angle and so on.
