* NOTE 1: This project provides two demo applications. A simple blinky style
|
||||
* project, and a more comprehensive test and demo application that makes use of
|
||||
* the FreeRTOS+CLI, FreeRTOS+UDP and FreeRTOS+FAT SL components. 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,
|
||||
* which is fully documented on the following URL:
|
||||
* http://www.FreeRTOS.org/Atmel_SAM4E_RTOS_Demo.html
|
||||
*
|
||||
* 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.

* + Registers sample generic, file system related and UDP related commands
|
||||
* with FreeRTOS+CLI.
|
||||
* + Creates all the standard demo application tasks and software timers.
|

* + Starts the scheduler.
|

|

* A UDP command server and optionally two UDP echo client tasks are created
|
||||
* from the network event hook after an IP address has been obtained. The IP
|
||||
* address is displayed on the LCD.
|
||||
*
|
||||
* A "check software timer" is created to provide visual feedback of the system
|
||||
* status. The timer's period is initially set to three seconds. The callback
|
||||
* function associated with the timer checks all the standard demo tasks are not
|
||||
* only still executed, but are executing without reporting any errors. If the
|
||||
* timer discovers a task has either stalled, or reported an error, then it
|
||||
* changes its own period from the initial three seconds, to just 200ms. The
|
||||
* check software timer also toggles the LED marked D4 - so if the LED toggles
|
||||
* every three seconds then no potential errors have been found, and if the LED
|
||||
* toggles every 200ms then a potential error has been found in at least one
|

|
