51单片机控制的步进电机C语言程序

1、我上周刚做的这个实验成功拉,给你参考一下吧这可是我当时辛辛苦苦编出来的啊,不过我用的是 L298驱动的 和ULN2003H样,你把它换成2003 就行拉#include <AT89X51.H>unsigned char code table=0xf1,0xf3,0xf2,0xf6,0xf4,0xfc,0xf8,0xf 9,0x00,0xf1,0xf9,0xf8,0xfc,0xf4,0xf6,0xf2,0xf3,0x00;unsigned chartemp,temp_old;unsigned charkey;unsigned chari,j,k,m,s;void delay(inti

2、)for(m=i;m>0;m-)for(j=250;j>0;j-)for(k=10;k>0;k-);void saomiao()P3=0xff;P3_4=0;temp=P3;temp=temp&0x0f;if(temp!=0x0f)for(i=50;i>0;i-)for(j=200;j>0;j-);temp=P3;temp=temp&0x0f;if(temp!=0x0f)(temp=P3;temp=temp&0x0f;switch(temp)(case 0x0e:key=1;break;case 0x0d:key=2;break;case

3、0x0b:key=3;break;case 0x07:key=4;break;temp=P3;temp=temp&0x0f;while(temp!=0x0f)(temp=P3;temp=temp&0x0f;P3=0xff;P3_5=0;temp=P3;temp=temp&0x0f;if(temp!=0x0f)(for(i=50;i>0;i-)for(j=200;j>0;j-);temp=P3;temp=temp&0x0f;if(temp!=0x0f)(temp=P3;temp=temp&0x0f;switch(temp)case 0x0d:k

4、ey=5;break;case 0x0b:key=6;break;case 0x07:key=7;break;temp=P3;temp=temp&0x0f;while(temp!=0x0f)(temp=P3;temp=temp&0x0f;void main(void)(while(1)(saomiao();if(key=1)( P1=0;P2=0;saomiao();if(key=2)(temp_old=key;for(s=0;s<8;s+)( P2=tables;P1_4=0;delay(13);saomiao();if(key!=temp_old)(P1_4=1;br

5、eak;if(key=3)(temp_old=key;for(s=0;s<8;s+)( P2=tables;P1_5=0;delay(5);saomiao();if(key!=temp_old)(P1_5=1;break;if(key=4)(temp_old=key;for(s=0;s<8;s+)( P2=tables;P1_6=0;delay(20);saomiao();if(key!=temp_old)(P1_6=1;break;if(key=5)(temp_old=key;for(s=9;s<17;s+)( P2=tables;P1_7=0;delay(13);saomiao();if(key!=temp_old)(P1_7=1;break;if(key=6)(temp_old=key;for(s=9;s<17;s+)( P2=tables;P1_5=0;delay(5);saomiao();if(key!=temp_old)(P1_5=1;break;if(key=7)(temp_old=key;f
