/******************************************************************************
* 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
* basic 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, writes 'Blink' to the UART
* (the UART is used in place of the LED to allow easy execution in QEMU). 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 five 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.".
