你想用定時器來延時嗎？很好處理呀比如

#include

#define uchar unsigned char;

#define uint unsigned int;

uchar times;

uint delaytime;

bit flag=00h;

void t0isr() interrupt 1

{

TH0=(65536-delaytime)/256;

TL0=(65536-delaytime)%256;

times--;

if(times==0) flag=1;

}

main()

{

TMOD=0x01;

ET0=1;

EA=1;

//比如延時100s

delaytime=1000;//1ms

times=100;//調整delaytime,times來調整延時時間

TR0=1;

flag=0;

while(flag==0);//等待延時時間到

while(1);

}
