/******************************************************************************
* 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 200 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 200 milliseconds.
*
* 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 the 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 200 milliseconds, the queue receive
* task leaves the Blocked state every 200 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 a software timer, 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:
*
* "Check" timer - The check software timer period is initially set to three
* seconds. The callback function associated with the check software timer
* checks that all the standard demo tasks are not only still executing, but
* are executing without reporting any errors. If the check software timer
* 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 software timer callback function also toggles the green
* LED each time it is called. This provides a visual indication of the system
* status: If the green LED toggles every three seconds, then no issues have
* been discovered. If the green LED toggles every 200ms, then an issue has
* been discovered with at least one task.
*
* FreeRTOS+CLI command console. The command console is access through UART0
* using 115200 baud and the Microsemi MSS UART drivers. Type "help" to see a
* list of registered commands, which include some basic file system commands
* (see FreeRTOS+FAT SL comments below). The FreeRTOS+CLI license is different
* to the FreeRTOS license, see http://www.FreeRTOS.org/cli for license and
* usage details.
*
* FreeRTOS+FAT SL. FreeRTOS+FAT SL is demonstrated using a RAM disk. [At the
* time of writing] The functionality of the file system demo is identical to
* the functionality of the FreeRTOS Win32 simulator file system demo with the
* command console being accessed via the UART (as described above) instead of
* a network terminal. The FreeRTOS+FAT SL license is different to the FreeRTOS
* license, see http://www.FreeRTOS.org/fat_sl for license and usage details,
* and a description of the file system demo functionality.
*
* See the documentation page for this demo on the FreeRTOS.org web site for
* full information, including hardware setup requirements.
