/******************************************************************************
|
||||||
|
* 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 software timers, 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:
|
||||||
|
*
|
||||||
|
* "Reg test" tasks - These fill both the core 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" task - The check executes every three seconds. It 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 task
|
||||||
|
* discovers that a task has either stalled, or reported an error, then it
|
||||||
|
* prints an error message to the UART, otherwise it prints "Pass.".
