定时, 定时中断, 主程序
各位大虾，我写的程序用了１０ＭＳ的定时中断，我用单步跟踪执行的时候发现，当时间到了之后啊，程序死在定时中断里面了　，不能回到主程序里了　　这是什么原因啊　大家帮帮忙哈　　小弟急啊　多谢了！

你的定时器是不是需要软件清中断标志啊...

程序如下 希望大家帮忙哈 谢谢

我在medvin里模拟仿真的时候  就可以返回的啊

随便说说

        DelayTime=15;       //  eliminate trembling
        while(DelayTime);
这个地方造成死机了吧....

6楼的正解

6楼的大虾能否告素我原因啊 
程序运行到这个地方就进中断了,当DelayTime=0时就继续向下执行,是不是程序有问题啊
还望多多指教 谢谢!

没有自减语句，delaytime怎么可能等于0

此处不懂

if(P2!=0XFF)
{DelayTime=15;
while(DelayTime);//等到定时中断，有可能是你要１５次中断程序后才跳出，因而你认为是不是一直在定时中断的原因
另：你中断程序用的是工作组１，而ＭＡＩＮ（）用的是工作组０，会不会
DelayTime在主程序和中断程序处理不在一起呢？

10楼的兄弟 多谢

我定义的是1ms定时中断
{DelayTime=15;
while(DelayTime);
此处为了键盘的消抖,故通过进入中断15次的延迟时间来消抖的
而且我用的是单步跟踪 他执行完中断子函数后,就死在最后哪个花括号那里了啊
但是我medwin模拟仿真了,执行完中断子函数后,就会自动返回主函数那里
为什么在KEIL C中就不可以呢 比较费解  麻烦各位了哈

我搞错了


Delaytime和工作组没有关系．
但我运行你的程序没有错，我把ＤelaTime的值和定时值减小了，运行好象没有问题，能回到主函数中．看如下程序
