标题: PIC16F877程序问题
#include<pic.h>
#define uchar unsigned char
#define uint unsigned int
__CONFIG(0x3B31);
void init();
uint intnum;
void main()
{

init();
while(1)
{
if(intnum==5)
{
intnum=0;
RD0=!RD0;
}
}
}

void init()
{
TRISD=0;
PORTD=0;
OPTION=0x07;
INTCON=0xa0;
TMR0=61;
}

void interrupt time0()
{
T0IF=0;
TMR0=61;
intnum++;
}

这是什么原因，程序写的没有问题啊

你试一下OPTION_REG呢

OPTION_REG可以，但中断函数还是报错什么问题

XC8编译器得用void __interrupt() ISR(void)
