K1K2分别控制定时器T0
#includesbit Beep = P1^0;sbit Led = P1^1;sbit K1 = P2^0;sbit K2 = P2^1;void ConfigTimer(){TMOD = 0x11;TH1 = 0xFC;TL1 = 0c18;TH0 = 0xFC;TL0 = 0x18;ET0 = 1;ET1 = 1;EA = 1;}void delay(int z){int i,j;for(i=0; i= 1000){Led = ~Led;t = 0;}}我刚写出来，，没有试验，你编译下，更改引脚定义，试试，，应该是可以的 #includesbit Beep = P1^0;sbit ...全部

。。 中断服务程序没有变，按键程序更改了一下，。收起
