|
||||||
|
* 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.

||||||

* basic demo. Generic functions, such FreeRTOS hook functions, and functions

|
||||||
|
******************************************************************************
|
||||||
|
*
|
||||||
|
* 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.

/******************************************************************************
|
||||||
|
* 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 comprehensive test and demo version.
|
||||||
|
*
|
||||||
|
* NOTE 2: This file only contains the source code that is specific to the
|
||||||
|
* full demo. Generic functions, such FreeRTOS hook functions, and functions
|
||||||
|
* required to configure the hardware, are defined in main.c.
|
||||||
|
******************************************************************************
|
||||||
|
*
|
||||||
|
* 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.
