* This file contains the implementation of MemGet class that provides functions to get
|
|
* information about free heap, heap size, free psram and psram size. The functions are
|
|
* implemented for ESP32 and NRF52 architectures. If the platform does not have heap
|
|
* management function implemented, the functions return UINT32_MAX or 0.
