How to determine the ''heap'' and ''stack'' size?

I am using Keil.  How should one determine what is the best size for the heap and stack?

Are there any common guidelines?

Thanks.

The common sense guidelines would be to understand how much memory you plan on malloc()ing, and how deep your call tree gets, and how large auto/local variables are.

Keil creates a static call graph in a .HTM file generated by the Linker.

Dynamically you can track malloc/free to get an idea of usage and maximal values. The stack depth can be checked, fill it with a marker character and review it periodically.
