/******************************************************************************
|
||||
* 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...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, toggles an 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.
