REM This file should be executed from the command line prior to the first

REM .bat file has been executed (normally just press F5 to refresh).
REM Copies all the required files from their location within the standard

/******************************************************************************
* 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.

******************************************************************************
*
* 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.
*
* See the documentation page for this demo on the FreeRTOS.org web site for
* full information, including hardware setup requirements.
