-/******************************************************************************
- * 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 simply blinky style version.
- *
- * NOTE 2: This file only contains the source code that is specific to the
- * blinky demo. Generic functions, such FreeRTOS hook functions, and functions
- * required to configure the hardware are defined in main.c.
- ******************************************************************************
- *
- * main_blinky() creates one queue, and two tasks. It then starts the
- * scheduler.
- *
- * The Queue Send Task:
- * The queue send task is implemented by the prvQueueSendTask() function in
- * this file. prvQueueSendTask() sits in a loop that causes it to repeatedly
- * block for 1000 milliseconds, before sending the value 100 to the queue that
- * was created within main_blinky(). Once the value is sent, the task loops
- * back around to block for another 1000 milliseconds...and so on.
- *
- * The Queue Receive Task:
- * The queue receive task is implemented by the prvQueueReceiveTask() function
- * in this file. prvQueueReceiveTask() sits in a loop where it repeatedly
- * blocks on attempts to read data from the queue that was created within
- * main_blinky(). When data is received, the task checks the value of the
- * data, and if the value equals the expected 100, toggles an LED. The 'block
- * time' parameter passed to the queue receive function specifies that the task
- * should be held in the Blocked state indefinitely to wait for data to be
- * available on the queue. The queue receive task will only leave the Blocked
- * state when the queue send task writes to the queue. As the queue send task
- * writes to the queue every 1000 milliseconds, the queue receive task leaves
- * the Blocked state every 1000 milliseconds, and therefore toggles the LED
- * every 200 milliseconds.

-/******************************************************************************
- * 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. The check task
- * toggles the LED every three seconds if all the standard demo tasks are
- * executing as expected, or every 500ms if a potential error is discovered in
- * any task.
