*******************************************************************************
|
||||
* NOTE 1: The POSIX port is a simulation (or is that emulation?) only! Do not
|
||||
* expect to get real time behaviour from the POSIX port or this demo
|
||||
* application. It is provided as a convenient development and demonstration
|
||||
* test bed only.
|
||||
*
|
||||
* Linux will not be running the FreeRTOS simulator threads continuously, so
|
||||
* the timing information in the FreeRTOS+Trace logs have no meaningful units.
|
||||
* See the documentation page for the Linux simulator for an explanation of
|
||||
* the slow timing:
|
||||
* https://freertos-wordpress.corp.amazon.com/FreeRTOS-simulator-for-Linux.html
|
||||
* - READ THE WEB DOCUMENTATION FOR THIS PORT FOR MORE INFORMATION ON USING IT -
|
||||
*
|
||||
* NOTE 2: 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 3: This file only contains the source code that is specific to the
|
||||
* full demo. Generic functions, such FreeRTOS hook functions, are defined in
|
||||
* main.c.
|
||||
*******************************************************************************
|
||||
*
|
||||
* main() creates all the demo application tasks, 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:
|
||||
*
|
||||
* "Check" task - This only executes every five seconds but has a high priority
|
||||
* to ensure it gets processor time. Its main function is to check that all the
|
||||
* standard demo tasks are still operational. While no errors have been
|
||||
* discovered the check task will print out "OK" and the current simulated tick
|
||||
* time. If an error is discovered in the execution of a task then the check
|
||||
* task will print out an appropriate error message.
