用C语言实现对直流电机和步进电机进行正反转控制〈用ULN2003A和AT89C51芯片〉的程序

Answer 1

#include <reg52.h>
//unsigned char code F_Rotation[4]={0x12,0x06,0x0c,0x18};
//unsigned char code F_Rotation[8]={0x12,0x02,0x06,0x04,0x0c,0x08,0x18,0x10};//一二相激励
unsigned char code F_Rotation[4]={0x02,0x04,0x08,0x10};//正转表格
unsigned char code B_Rotation[4]={0x10,0x08,0x04,0x02};//反转表格

void Delay(unsigned int i)//延时
{
while(--i);
}

main()
{

unsigned char i;

while(1)
{
for(i=0;i<4;i++) //4相
{
P1=F_Rotation[i]; //输出对应的相 可以自行换成反转表格
Delay(280); //改变这个参数可以调整电机转速
}
}
}
