步进电机角度控制

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,0x66,0x6d,0x7d,0x07, 0x7f,0x6f,0x77,0x7c,0x39,0x5e,0x79,0x71;uint m=0;uchar a3,a2,a1,a0=0;void delay(uint xms)uint i,j;for(i=xms;i0;i-)for(j=110;j0;j-);void display()outp(PA,teblea0);outp(PB,0x07);delay(10);

2、outp(PA,teblea1);outp(PB,0x0b);delay(10);outp(PA,teblea2);outp(PB,0x0d);delay(10);outp(PA,teblea3);outp(PB,0x0e);delay(10);void zhuan(uint zz)uint temp,i,j;a3=zz/1000a2=(zz%1000)/100;a1=(zz%100)/10;a0=(zz%10);temp=(uint)(zz/15*4);for(i=temp;i0;i-) for(j=3;j0;j-)display();outp(PC,paim);m+;if(m7)m=0;void main()int i;outp(CTRL,0x88);while(1)zhuan(180);for(i=75;i0;i-)display();zhuan(45);for(i=75;i0;i-)display();zhuan(90);for(i=75;i0;i-)display();2. 完成A/D转换实验并把转换结果在七段LED上显示出来。#include #define uchar u
