-/******************************************************************************
- * 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.
