正反轉(zhuǎn)可通過(guò)按鍵控制直流電機(jī)，代碼如下
/*************** writer:shopping.w ******************/
#include <reg52.h>
#include <intrins.h>
#define uint unsigned int
#define uchar unsigned char
sbit K1 = P3^0;
sbit K2 = P3^1;
sbit K3 = P3^2;
sbit LED1 = P0^0;
sbit LED2 = P0^1;
sbit LED3 = P0^2;
sbit MA = P1^0;
sbit MB = P1^1;
void main(void)
{
LED1 = 1;
LED2 = 1;
LED3 = 0;
while(1)
{
if(K1 == 0)
  {
while(K1 == 0);
LED1 = 0;
LED2 = 1;
LED3 = 1;
MA = 0;
MB = 1;
  }
  if(K2 == 0)
  {
while(K1 == 0)
LED2 = 0;
LED3 = 1;
MA = 1;
MB = 0;
  }
  {
while(K1 == 0);
LED1 = 1;
LED2 = 1;
LED3 = 0;
MA = 0;
MB = 0;
  }
}
}

k2中while后面是k2==0，還有最后一個(gè)while沒(méi)看懂，k1又是正轉(zhuǎn)又是停止
