#include "REG52.H"sbit LED1_01 = P1^1; //LED灯sbit KEY0_01 = P1^2; //按键void Delay_1ms(unsigned int Time){unsigned int x, y;for(x = Time; x > 0; x--)for(y = 120; y > 0; y--);}int main(void){LED1_01 = 1; //打开LED灯点亮while(1){if(KEY0_01 == 0) //检测按键是否按下{Delay_1ms(10); //延时去抖动if(KEY0_01 == 0) //确定按键按下{LED1_01 = ~ LED1_01; //取反LED灯 [ 亮 . 灭 ]}while(KEY0_01 == 0); //检测松手}}}

你可以自己设置一下，我可以帮你
