/******************************************************************************
|
||||
* 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:
|
||||
*
|
||||
* FreeRTOS+CLI command console. The command console is access through UART2
|
||||
* using 115200 baud if mainINCLUDE_FAT_SL_DEMO is set to 1. For reasons of
|
||||
* robustness testing the UART driver is deliberately written to be inefficient
|
||||
* and should not be used as a template for a production driver. Type "help" to
|
||||
* see a list of registered commands. The FreeRTOS+CLI license is different to
|
||||
* the FreeRTOS license, see http://www.FreeRTOS.org/cli for license and usage
|
||||
* details.
|
||||
*
|
||||
* FreeRTOS+FAT SL. FreeRTOS+FAT SL is demonstrated using a RAM disk if
|
||||
* mainINCLUDE_FAT_SL_DEMO is set to 1. [At the time of writing] The
|
||||
* functionality of the file system demo is identical to the functionality of
|
||||
* the FreeRTOS Win32 simulator file system demo, with the command console being
|
||||
* accessed via the UART (as described above) instead of a network terminal.
|
||||
* The FreeRTOS+FAT SL license is different to the FreeRTOS license, see
|
||||
* http://www.FreeRTOS.org/fat_sl for license and usage details, and a
|
||||
* description of the file system demo functionality.
|
||||
*
|
||||
* "Reg test" tasks - These fill both the core and floating point 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 task period is initially set to three seconds. The
|
||||
* task 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 changes its own execution period from the initial three
|
||||
* seconds, to just 200ms. The check task also toggles an 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.
