You can then check the maximum stack usage by checking the address from the beginning of the stack that were overwritten. #### Fill the stack section by a known pattern: @@ -216,7 +216,7 @@ According to my experimentations, we don't use the stack that much, and 8192 byt ### Heap -The heap is declared in the [linker script](https://github.com/InfiniTimeOrg/InfiniTime/blob/develop/nrf_common.ld#L136) and its current size is 8192 bytes.
