-/******************************************************************************
- * 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.".
