/******************************************************************************
|
||||
* 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.
|
||||
*
|
||||
* 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 a set of standard demo tasks, some application specific
|
||||
* tasks, and a timer. It 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 timer are
|
||||
* defined and/or created within this file:
|
||||
*
|
||||
* "Reg test" tasks - These fill the registers with known values, then check
|
||||
* that each register maintains its expected value for the lifetime of the
|
||||
* task. Each task uses a different set of values. The reg test tasks execute
|
||||
* with a very low priority, so get preempted very frequently. A register
|
||||
* containing an unexpected value is indicative of an error in the context
|
||||
* switching mechanism.
|
||||
*
|
||||
* "Check" software timer - The check timer period is initially set to three
|
||||
* seconds. Its callback function checks that all the standard demo tasks, and
|
||||
* the register check tasks, are not only still executing, but are executing
|
||||
* without reporting any errors. If the check timer callback discovers that a
|
||||
* task has either stalled, or reported an error, then it changes the period of
|
||||
* the check timer from the initial three seconds, to just 200ms. The callback
|
||||
* function also toggles the LED each time it is called. This provides a
|
||||
* visual indication of the system status: If the LED toggles every three
|
||||
* seconds then no issues have been discovered. If the LED toggles every 200ms,
|
||||
* then an issue has been discovered with at least one task.
