/******************************************************************************
* 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.
******************************************************************************
*
* See http://www.FreeRTOS.org/RTOS_Intel_Quark_Galileo_GCC.html for usage
* instructions.
*
* 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...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, outputs a message to the COM
* port. 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 writes to
* the COM port every 200 milliseconds.
