* This file implements the code that is not demo specific, including the
* hardware setup and FreeRTOS hook functions.

timer or semaphore is created. It is also called by various parts of the
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

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
function, because it is the responsibility of the idle task to clean up
memory allocated by the kernel to any task that has since been deleted. */
