pvPortMalloc() is called internally by the kernel whenever a task, queue,

demo application. If heap_1.c or heap_2.c are used, then the size of the

heap available to pvPortMalloc() is defined by configTOTAL_HEAP_SIZE in
|
|
FreeRTOSConfig.h, and the xPortGetFreeHeapSize() API function can be used

to query the size of free heap space that remains (although it does not

provide information on how the remaining heap might be fragmented). */

to block in any way (for example, call xQueueReceive() with a block time

|
specified, or call vTaskDelay()). If the application makes use of the
|
|
vTaskDelete() API function (as this demo application does) then it is also
|

important that vApplicationIdleHook() is permitted to return to its calling
