Memory usage

Question

Hi Gents,

 Is there any method to get an idea of what is using up flash and stack/heap space within a project? I'm just starting out on a project and would like to know where resource hogs and inefficienies might be in what we cook up.

Thank you,

Hello Mike,

the typical approach in such case is:

- analyze the linker MAP file in order to get the flash size needed for the application. In the MAP file you see also the allocation for stack and static/global variables.

- To get the RAM usage (heap) use the function EwPrintProfilerStatistic().This function should usually be called at the end of each loop in the GUI main function.
