An easy way to monitor its usage is by filling the section with a known pattern at boot time, then use the firmware and dump the memory. 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.
