怎么知道PSoC5使用多少堆栈

你好，
我使用的PSoC 5的一个项目，想知道用多少堆栈存储器。有人知道效用函数用于这个目的吗？
我现在分配8K型堆栈，认为它应该是足够的但想知道它实际上是什么比例。希望不要发布产品后有一个堆栈溢出问题。
我已经用0x55填充内存堆栈做同样的checkingfor PSoC 1项目检查堆栈内存运行到后几天的项目做产品的所有功能。我知道这不是100%不得行使最大的组合，但是它给至少一个更好的价值比只是客串。
任何一个与GCC ARM编译器的经验告诉我如何做得到？还是可以使用的实用函数？
谢谢

  Hi,
    I have a project using PSoC 5 and would like to know how much stack memory is being used. Does anyone aware of utility function for this purpose?
    I am now assigning 8k for the stack and think it should be enought but would like to know what percentage it acutally is being used. Don't want to have a stack overflow problem after releasing the product.
    I have do the same checking for a PSoC 1 project by filling the stack RAM with 0x55 and check the stack RAM after runing to project for a few days and try to perform all the function of the product. I know it is not 100% as it may not exercise the wrost combination but it would give at least a better value than just guesting.
    Any one has experience with GCC ARM compiler to show me how it can be done? or utility functions that can be used?
    Thanks
