/******************************************************************************
* 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 microcontroller 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 task period is initially set to three seconds. The
* task 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 changes its own execution period from the initial three
* seconds, to just 200ms. The check task also toggles an LED each time it is
* called. This provides a visual indication of the system status: If the LED
* toggles every three seconds, then no issues have been discovered. If the LED
* toggles every 200ms, then an issue has been discovered with at least one
* task.
