## FreeRTOS heap and task stack ## FreeRTOS heap and task stack
FreeRTOS statically allocate its own heap buffer in a global variable named `ucHeap`. This is an aray of *uint8_t*. Its size is specified by the definition `configTOTAL_HEAP_SIZE` in *FreeRTOSConfig.h* FreeRTOS statically allocate its own heap buffer in a global variable named `ucHeap`. This is an array of *uint8_t*. Its size is specified by the definition `configTOTAL_HEAP_SIZE` in *FreeRTOSConfig.h*
FreeRTOS uses this buffer to allocate memory for tasks stack and all the RTOS object created during runtime (timers, mutexes,...). FreeRTOS uses this buffer to allocate memory for tasks stack and all the RTOS object created during runtime (timers, mutexes,...).
The function `xPortGetFreeHeapSize()` returns the amount of memory available in this *ucHeap* buffer. If this value reaches 0, FreeRTOS runs out of memory.
