How to calculate required stack and heap values ​​in CubeMx when using hal usb?

Question

Microcontrollers

In the usb-audio project on hal usb mono 8kHz 16b, how to calculate the required stack and heap values ​​​​and determine whether a certain microcontroller has enough memory for such stack and heap values?

Answer 1

To determine the stack size in gcc, use the -fstack-usage flag when compiling.
As a result, a .su file will appear, which you can parse some avstack.pl and see how much of the stack is consumed in total, and how much in each individual function.
With a heap, this will not work - it allocates memory dynamically. You can search for all *malloc in the code you're using, for example.
