+/******************************************************************************\r
+ * NOTE 1: This project provides two demo applications. A simple blinky style\r
+ * project, and a more comprehensive test and demo application that makes use of\r
+ * the FreeRTOS+CLI, FreeRTOS+UDP and FreeRTOS+FAT SL components. The\r
+ * mainCREATE_SIMPLE_BLINKY_DEMO_ONLY setting in main.c is used to select\r
+ * between the two. See the notes on using mainCREATE_SIMPLE_BLINKY_DEMO_ONLY\r
+ * in main.c. This file implements the comprehensive test and demo version,\r
+ * which is fully documented on the following URL:\r
+ * http://www.FreeRTOS.org/Atmel_SAM4E_RTOS_Demo.html\r
+ *\r
+ * NOTE 2: This file only contains the source code that is specific to the\r
+ * full demo. Generic functions, such FreeRTOS hook functions, and functions\r
+ * required to configure the hardware, are defined in main.c.\r
+ ******************************************************************************\r
+ *\r
+ * Full user instructions are provided on the following URL:\r
+ * http://www.FreeRTOS.org/Atmel_SAM4E_RTOS_Demo.html\r
+ *\r
+ * main_full():\r
+ * + Uses FreeRTOS+FAT SL to create a set of example files on a RAM disk.\r
+ * + Displays some bitmaps on the LCD.\r
+ * + Registers sample generic, file system related and UDP related commands\r
+ * with FreeRTOS+CLI.\r
+ * + Creates all the standard demo application tasks and software timers.\r
+ * + Starts the scheduler.\r
+ *\r
+ * A UDP command server and optionally two UDP echo client tasks are created\r
+ * from the network event hook after an IP address has been obtained. The IP\r
+ * address is displayed on the LCD.\r
+ *\r
+ * A "check software timer" is created to provide visual feedback of the system\r
+ * status. The timer's period is initially set to three seconds. The callback\r
+ * function associated with the timer checks all the standard demo tasks are not\r
+ * only still executed, but are executing without reporting any errors. If the\r
+ * timer discovers a task has either stalled, or reported an error, then it\r
+ * changes its own period from the initial three seconds, to just 200ms. The\r
+ * check software timer also toggles the LED marked D4 - so if the LED toggles\r
+ * every three seconds then no potential errors have been found, and if the LED\r
+ * toggles every 200ms then a potential error has been found in at least one\r
+ * task.\r
+ *\r
+ * Information on accessing the CLI and file system, and using the UDP echo\r
+ * tasks is provided on http://www.FreeRTOS.org/Atmel_SAM4E_RTOS_Demo.html\r
