单片机四线步进电机驱动 程序功能：

当按下SW1时步进电机正转，按下SW2后步进电机反转，并可以根据源码任意调节旋转速度和每一个脉冲旋转角度

程序参考源代码如下：

/C语言程序:/

#include //可用非常成功。

#define uchar unsigned char

#define uint unsigned int

uchar table_begin;

uint maichong; //脉冲

uchar zhuansu; //转速

sbit key_z=P3^1; //正转键

sbit key_f=P3^2; //反转键

sbit key_jia=P3^3; //加速键

sbit key_jian=P3^6; //减速键

sbit A1=P2^0;

sbit A2=P2^1;

sbit A3=P2^2;

sbit A4=P2^3;
