Question

c51编程疑问 请各路大神帮忙

#include<reg51.h>
#include<stdio.h>
#define uint unsigned int

sbit outled=P1;
sbit gndH=P2^4;
sbit gndL=P2^5;
sbit key1=P0^0;//out
sbit key2=P0^1;
sbit key3=P0^2;
sbit key4=P0^3;
sbit key5=P0^4;//in
sbit key6=P0^5;
sbit key7=P0^6;
sbit key8=P0^7;

bit clock;
bit BJ;
sbit fm=P3^7; //蜂鸣报警口，低电平有效
uint s;
uint t;

void main()
{ uint a;
t=0;s=0;
IT0=1;
EX0=1;
EA=1;

while(1)
{
a=10*t+s;
Delay(100);

led8(a);
}
}
void ex0() interrupt0 //中断子程序
{
t=Sm();
s=Sm();
}
出错出在最后的中断子程序 不明白怎么错了 请大神指出 多谢~

#include<reg51.h>

#define outled P1;

sbit gndH = P2^4;
sbit gndL = P2^5;
sbit key1 = P0^0;//out
sbit key2 = P0^1;
sbit key3 = P0^2;
sbit key4 = P0^3;

sbit key6 = P0^5;
sbit key7 = P0^6;
sbit key8 = P0^7;

bit clock;

uint s;
uint t;

void main()

{
uint a;
t = 0;s = 0;

IT0 = 1;
EX0 = 1;
EA = 1;

while(1) {
a = 10 * t + s;
// Delay(100);
// led8(a);
}
}

void ex0() interrupt 0 //中断子程序
{
// t = Sm();
// s = Sm();
