The stack 'cstack' is filled to 92% (368 bytes used out of 400). The warning threshold I

The IAR warning indicates that cstack has filled up with 92%. This warning will not appear only when it is below 90%.

Previously, the cstack size I set was 400 bytes.

 

A. STACK: the stack is automatically allocated and released by the compiler, and stores function parameter values and local variable values. The operation method is similar to the stack in the data structure.

B. HeapProgramMembers are assigned to release the program. If the programmer does not release the program, it may be recycled by the OS at the end of the program. Note that it is different from the heap in the data structure. The allocation method is similar to the linked list.

 

Cstack is used by the system. It is used by the compiler for automatic allocation. How small is it now ??
