+/******************************************************************************
+ * NOTE 1: This project provides two demo applications. A simple blinky style
+ * project, and a more comprehensive test and demo application. The
+ * mainCREATE_SIMPLE_BLINKY_DEMO_ONLY setting in main.c is used to select
+ * between the two. See the notes on using mainCREATE_SIMPLE_BLINKY_DEMO_ONLY
+ * in main.c. This file implements the comprehensive test and demo version.
+ *
+ * NOTE 2: This file only contains the source code that is specific to the
+ * full demo. Generic functions, such FreeRTOS hook functions, and functions
+ * required to configure the hardware, are defined in main.c.
+ *
+ ******************************************************************************
+ *
+ * main_full() creates all the demo application tasks and software timers, then
+ * starts the scheduler. The web documentation provides more details of the
+ * standard demo application tasks, which provide no particular functionality,
+ * but do provide a good example of how to use the FreeRTOS API.
+ *
+ * In addition to the standard demo tasks, the following tasks and tests are
+ * defined and/or created within this file:
+ *
+ * "Reg test" tasks - These fill both the core registers with known values, then
+ * check that each register maintains its expected value for the lifetime of the
+ * task. Each task uses a different set of values. The reg test tasks execute
+ * with a very low priority, so get preempted very frequently. A register
+ * containing an unexpected value is indicative of an error in the context
+ * switching mechanism.
+ *
+ * "Check" task - The check executes every three seconds. It checks that all
+ * the standard demo tasks, and the register check tasks, are not only still
+ * executing, but are executing without reporting any errors. If the check task
+ * discovers that a task has either stalled, or reported an error, then it
+ * prints an error message to the UART, otherwise it prints "Pass.".
