以下是雙速電機(jī)的代碼和proteus與大家共享

單片機(jī)源程序如下:
#include<reg51.h>
#define uchar unsigned char
#define uint unsigned int
sbit KEY1=P2^0;
sbit KEY2=P2^1;
sbit KEY3=P2^2;

sbit CONTR1=P2^3;
sbit CONTR2=P2^4;
void DelayMS(uint x)
{
uchar i;
      while(x--)
      {
         for(i=0;i<120;i++);
      }
}
void KEYSCAN()
{
  if(KEY1==0)
{
DelayMS(2);
if(KEY1==0)
{
   while(!KEY1);
      CONTR1=0;
      CONTR2=1;
      }
}

  if(KEY2==0)
{
DelayMS(2);
if(KEY2==0)
{
   while(!KEY2);
      CONTR1=1;
      CONTR2=0;
      }
}
{
  if(KEY3==1)
{
DelayMS(2);
if(KEY3==0)
{
   while(!KEY3);
      CONTR1=1;
      CONTR2=1;
      }
}

}
}
void main()
{
  while(1)
  {
KEYSCAN();
}
}
