1、这里，我直接将代码给大家方便大家理解，参考代码：#include<reg52.h>sbitMotor_L=P1^0;sbitMotor_R=P1^1;sbitK0=P0^0;sbitK2=P0^2;sbitK1=P0^1;sbitK3=P0^3;
2、unsignedchartime2s;/*定时器0初始化函数*/voidInitTimer0(){TMOD%=0xF0;TMOD|=0x01;//定时器0，方式一TH0=(65536-50000)/256;TL0=(65536-50000)%256;//定时50msIE|=0x82;
3、 TR0=1;}voidmain(){Motor_L=Motor_R=1;InitTimer0();while(1){
4、 if(K0|K2){Motor_L=0;Motor_R=1;time2s=40;//2s}if(K1|K3){
5、 Motor_L=1;Motor_R=0;time2s=40;}娅势毁歹}}voidT0_INT()interrupt1{TH0=(65536-50000)/25鲂番黟谊6;TL0=(65536-50000)%256;if(time2s){time2s--;}else{Motor_L=Motor_R=1;}}
