+/******************************************************************************\r
+ * NOTE 1: This project provides two demo applications. A simple blinky\r
+ * style project, and a more comprehensive test and demo application. The\r
+ * mainCREATE_SIMPLE_BLINKY_DEMO_ONLY setting in main.c is used to\r
+ * select between the two. See the notes on using\r
+ * mainCREATE_SIMPLE_BLINKY_DEMO_ONLY in main.c. This file implements the\r
+ * comprehensive 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 and floating point registers with\r
+ * known values, then check that each register maintains its expected value for\r
+ * the lifetime of the task. Each task uses a different set of values. The reg\r
+ * test tasks execute with a very low priority, so get preempted very\r
+ * frequently. A register containing an unexpected value is indicative of an\r
+ * error in the context switching mechanism.\r
+ *\r
+ * "Check" task - The check task period is initially set to three seconds. The\r
+ * task checks that all the standard demo tasks, and the register check tasks,\r
+ * are not only still executing, but are executing without reporting any errors.\r
+ * If the check task discovers that a task has either stalled, or reported an\r
+ * error, then it changes its own execution period from the initial three\r
+ * seconds, to just 200ms. The check task also toggles an LED each time it is\r
+ * called. This provides a visual indication of the system status: If the LED\r
+ * toggles every three seconds, then no issues have been discovered. If the LED\r
+ * toggles every 200ms, then an issue has been discovered with at least one\r
+ * task.\r
