|
||||
* 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

* 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

* the LED every 200 milliseconds.
