* main-blinky.c is included when the "Blinky" build configuration is used.
|
||||||
|
* main-full.c is included when the "Full" build configuration is used.
|
||||||
|
*
|
||||||
|
* main-full.c (this file) defines a comprehensive demo that creates many
|
||||||
|
* tasks, queues, semaphores and timers. It also demonstrates how Cortex-M3
|
||||||
|
* interrupts can interact with FreeRTOS tasks/timers.
|
||||||
|
*
|
||||||
|
* This project runs on the SK-FM3-100PMC evaluation board, which is populated
|
||||||
|
* with an MB9BF5006N Cortex-M3 based microcontroller.
|
||||||
|
*
|
||||||
|
* The main() Function:
|
||||||
|
* main() creates three demo specific software timers, one demo specific queue,
|
||||||
|
* and two demo specific tasks. It then creates a whole host of 'standard
|
||||||
|
* demo' tasks/queues/semaphores, before starting the scheduler. The demo
|
||||||
|
* specific tasks and timers are described in the comments here. The standard
|
||||||
|
* demo tasks are described on the FreeRTOS.org web site.
|
||||||
|
*
|
||||||
|
* The standard demo tasks provide no specific functionality. They are
|
||||||
|
* included to both test the FreeRTOS port, and provide examples of how the
|
||||||
|
* various FreeRTOS API functions can be used.
|
||||||
|
*
|
||||||
|
* This demo creates 43 tasks in total. If you want a simpler demo, use the
|
||||||
|
* Blinky build configuration.
|
||||||
|
*
|
||||||
|
* The Demo Specific LED Software Timer and the Button Interrupt:
|
||||||
|
* The user button SW2 is configured to generate an interrupt each time it is
|
||||||
|
* pressed. The interrupt service routine switches an LED on, and resets the
|
||||||
|
* LED software timer. The LED timer has a 5000 millisecond (5 second) period,
|
||||||
|
* and uses a callback function that is defined to just turn the LED off again.
|
||||||
|
* Therefore, pressing the user button will turn the LED on, and the LED will
|
||||||
|
* remain on until a full five seconds pass without the button being pressed.
|
||||||
|
* See the documentation page for this demo on the FreeRTOS.org web site to see
|
||||||
|
* which LED is used.
|
||||||
|
*
|
||||||
|
* The Demo Specific "Check" Callback Function:
|
||||||
|
* This is called each time the 'check' timer expires. The check timer
|
||||||
|
* callback function inspects all the standard demo tasks to see if they are
|
||||||
|
* all executing as expected. The check timer is initially configured to
|
||||||
|
* expire every three seconds, but will shorted this to every 500ms if an error
|
||||||
|
* is ever discovered. The check timer callback toggles the LED defined by
|
||||||
|
* the mainCHECK_LED definition each time it executes. Therefore, if LED
|
||||||
|
* mainCHECK_LED is toggling every three seconds, then no error have been found.
|
||||||
|
* If LED mainCHECK_LED is toggling every 500ms, then at least one errors has
|
||||||
|
* been found. The variable pcStatusMessage is set to a string that indicates
|
||||||
|
* which task reported an error. See the documentation page for this demo on
|
||||||
|
* the FreeRTOS.org web site to see which LED in the 7 segment display is used.
|
||||||
|
*
|
||||||
|
* The Demo Specific Idle Hook Function:
|
||||||
|
* The idle hook function demonstrates how to query the amount of FreeRTOS heap
|
||||||
|
* space that is remaining (see vApplicationIdleHook() defined in this file).
|
||||||
|
*
|
||||||
|
* The Demo Specific Tick Hook Function:
|
||||||
|
* The tick hook function is used to test the interrupt safe software timer
|
||||||
|
* functionality.
