/****************************************************************************** | |
* This project provides two demo applications. A simple blinky style project, | |
* and a more comprehensive application that includes FreeRTOS+CLI, FreeRTOS+UDP | |
* and FreeRTOS+FAT SL. The mainCREATE_SIMPLE_BLINKY_DEMO_ONLY setting (defined | |
* in this file) is used to select between the two. The simply blinky demo is | |
* implemented and described in main_blinky.c. The more comprehensive demo | |
* application is implemented and described in main_full.c and full user | |
* instructions are provided on the following URL: | |
* http://www.FreeRTOS.org/Atmel_SAM4E_RTOS_Demo.html | |
* | |
* This file implements the code that is not demo specific, including the | |
* hardware setup and FreeRTOS hook functions. | |

pvPortMalloc() is called internally by the kernel whenever a task, queue, | |
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 | |
to query the size of free heap space that remains (although it does not | |
provide information on how the remaining heap might be fragmented). | |
Just count the number of malloc fails as some failures may occur simply | |
because the network load is very high, resulting in the consumption of a | |
lot of network buffers. */ | |

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 | |
function, because it is the responsibility of the idle task to clean up | |
