俺也是菜鸟，这么简单的破程序居然花了半个小时
好吧，我查中断号花了不少时间
//8个LED灯，没中断产生时，8个LED灯闪烁，当按下外部中断0按钮时，LED灯2468亮，当按下外部中断1时，LED灯1357亮
#include<reg51.h>
char Flag=0;
//不准确的延时函数
void Delay(unsigned int a)
{
unsigned char b;
for(;a>0;a--)
{
for(b=110;b>0;b--);
}
}
void main(void)
{
IT0=1;
EX0=1;
IT1=1;
EX1=1;
PX0=0;
PX1=0;
EA=1;
P1=0;
while(1)
{
if(Flag==1)
{
Delay(10000);
Flag=0;
P1=0;
}
P1=~P1;
Delay(1000);
}
}
void int0()interrupt 0
{
P1=0xAA;
Flag=1;
}
void int1()interrupt 2
{
P1=0x55;
Flag=1;
}
