1、步进电机控制器本毕设控制器采用STC89C52RC单片机，步进电机驱动采用ULN2003，利用液晶1602显示设置参数和运行状态。通过设置实现对步进电机，转动度数、转动方向的控制。程序：#include #define uchar unsigned char#define uint unsigned intvoid init();void writec(uint com);void writed(uint dat);void delay(uint shu);void xieshuzu(uchar a,uchar add);void kaiji();void option_turn(uchar
