关于IAR使用的一个疑问！！！请教高手~

这个选项卡里Stack Size代表堆栈大小，后面的Data16 heap是什么意思啊，该怎么设定呢？

heap是堆吧，不动态申请内存是用不到的，编译器也就不占用这些空间了，随便说说

非常感谢！看来就不用分配这么多heap空间啦

如果编译器给忽略掉，这里填多少也就无所谓了。

THE HEAP
The heap contains dynamic data allocated by the C function malloc (or one of its
relatives) or the C++ operator new.
If your application uses dynamic memory allocation, you should be familiar with:
● Linker segments used for the heap
● Allocating the heap size, which differs depending on which build interface you are
using
● Placing the heap segments in memory.
A heap is only included in the application if dynamic memory allocation is actually
used.

栈的大小基本也是不必操心的，编译器会最大限度的利用内存，实际没用到的内存基本都属于栈。

原来内存可以用作栈。但是我用IAR仿真430单片机的时候，如果栈设置比较小，就会有栈超过90%的警告！
