1、步进电机角度控制1. 编程控制步进电机顺时针行走，180度（角度显示在七段LED上），3秒后行走45度（显示角度），3秒后行走90度（显示角度），3秒后行走180度，依次循环。#include #define uchar unsigned char#define uint unsigned int#define PA 0x60#define PB 0x61#define PC 0x62#define CTRL 0x63uchar pai=0x01,0x03,0x02,0x06,0x04,0x0c,0x08,0x09;uchar teble=0x3f,0x06,0x5b,0x4f,0x66,0x
