Question

大家帮我看看这个单片机的c语言编程吧，不知道怎么的用keil编译总是说中断服务程序附近有错误，谢谢啦！

Answer 1

你程序中的子程序
void algorithm()
{
count++;
if(count == 20)
{
count = 0;
miao++;
if(miao == 60)
{
fen++;
miao = 0;
if(fen == 60)
{
shi++;
fen = 0;
if(shi == 24)
{
shi = 0;
}
}
}
大括号数目不平衡
这是修改以后的：
void algorithm()
{
count++;
if(count == 20)
{
count = 0;
miao++;
if(miao == 60)
{
fen++;
miao = 0;
if(fen == 60)
{
shi++;
fen = 0;
if(shi == 24)
{
shi = 0;
}
}
}
}
}
另外你程序中的
void timer0init()
{
TOMD=0x01;
TH0=(65536-46083)/256;
TL0=(65536-46083)%256;
EA=1;
ET0=1;
TR0=1;
}
子函数中
是TMOD不是TOMD
我就修改了这两处在我的keil2上运行0错误0警告
