+ * NOTE 1: This project provides two demo applications. A simple blinky style\r
+ * project, and a more comprehensive test and demo application. 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
+ *\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
+ *\r
+ * main_full() creates all the demo application tasks and software timers, then\r
+ * starts the scheduler. The web documentation provides more details of the\r
+ * standard demo application tasks, which provide no particular functionality,\r
+ * but do provide a good example of how to use the FreeRTOS API.\r
+ *\r
+ * In addition to the standard demo tasks, the following tasks and tests are\r
+ * defined and/or created within this file:\r
+ *\r
+ * "Reg test" tasks - These fill both the core registers with known values, then\r
+ * check that each register maintains its expected value for the lifetime of the\r
+ * task. Each task uses a different set of values. The reg test tasks execute\r
+ * with a very low priority, so get preempted very frequently. A register\r
+ * containing an unexpected value is indicative of an error in the context\r
+ * switching mechanism.\r
+ *\r
+ * "Check" task - The check executes every three seconds. It checks that all\r
+ * the standard demo tasks, and the register check tasks, are not only still\r
+ * executing, but are executing without reporting any errors. If the check task\r
+ * discovers that a task has either stalled, or reported an error, then it\r
+ * prints an error message to the UART, otherwise it prints "Pass.".\r
