中断设置标志，看不到标志改变

我是在做一个项目，我会实现一个启动按钮。
我的计划是初始化一切和进入一个while循环等待按钮代码这样的新闻：
布尔开始=假；
主体（）
{
初始化全部
而（！）开始）
{}
程序
}
然后有一个中断改变开始=真；
问题是我能看到的中断程序，但是程序不会离开而环。我试图打开一个LED在中断程序和读取输出引脚之后但不工作。
我已经隔离了问题这个档案，我放置了一个LED在端口1 [ 7 ]到GND和使用端口15，[ 5 ]按钮被拉低。
按下按钮应该打开LED。
一个按钮，任何工作的解决方案将是好的，但一个固定或理由的问题会很好的

  I am making an project where I would implement a start button.
My plan was to initialize everything and the enter a while loop waiting until the button was press with code like this:


bool START=false;
main()
{
Init all

while(!START)
{ }

Program
}

And then having a interrupt changing START=true;  

The problem is I can see the interrupt routine is called, but the program doesn't leave the while loop.
I have tried to turn on a LED in the interrupt routine and the read the output pin afterward but that doesn't work either.

I have isolated the problem to this archive, where i have placed an LED in port 1[7] to GND and uses Port 15[5] as button by pulling it low.
pressing the button should turn on the LED.

Any working solution for a button will be appriciated, but a fix or reason to the problem would be nice too
