/*
|
||||
* This project includes a lot of tasks and tests and is therefore complex.
|
||||
* If you would prefer a much simpler project to get started with then select
|
||||
* the 'Blinky' build configuration within the HEW IDE.
|
||||
*
|
||||
* 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. The tasks defined in flop.c are included in the
|
||||
* set of standard demo tasks to ensure the floating point unit gets some
|
||||
* exercise.
|
||||
*
|
||||
* 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 the registers with known values, then check
|
||||
* that each register still contains its expected value. Each task uses
|
||||
* different values. The tasks run with very low priority so get preempted very
|
||||
* frequently. A register containing an unexpected value is indicative of an
|
||||
* error in the context switching mechanism and will result in interrupts being
|
||||
* disabled and a branch to a null loop. This has the effect of stopping
|
||||
* execution of all the tests and tasks, which in turn results in all LED
|
||||
* activity stopping too. The nature of the reg test tasks necessitates that
|
||||
* they are written in assembly code. The check task (described below) checks
|
||||
* that the reg test tasks are still executing and will indicate an error if
|
||||
* either reg test task is found to have stalled.
|
||||
*
|
||||
* "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 toggle LED 5 every 5 seconds - the toggle
|
||||
* rate increasing to 200ms being a visual indication that at least one task has
|
||||
* reported unexpected behaviour.
|
||||
*
|
||||
* "High frequency timer test" - A high frequency periodic interrupt is
|
||||
* generated using a timer - the interrupt is assigned a priority above
|
||||
* configMAX_SYSCALL_INTERRUPT_PRIORITY so should not be effected by anything
|
||||
* the kernel is doing. The interrupt service routine measures the number of
|
||||
* counts a separate timer performs between each interrupt to determine the
|
||||
* jitter in the interrupt timing.
|
||||
*
|
||||
* *NOTE 1* If LED5 is toggling every 5 seconds then all the demo application
|
||||
* tasks are executing as expected and no errors have been reported in any
|
||||
* tasks. The toggle rate increasing to 200ms indicates that at least one task
|
||||
* has reported unexpected behaviour.
|
||||
*
|
||||
* *NOTE 2* vApplicationSetupTimerInterrupt() is called by the kernel to let
|
||||
* the application set up a timer to generate the tick interrupt. In this
|
||||
* example a compare match timer is used for this purpose.
|
||||
*
|
||||
* *NOTE 3* The CPU must be in Supervisor mode when the scheduler is started.
|
||||
* The PowerON_Reset_PC() supplied in resetprg.c with this demo has
|
||||
* Change_PSW_PM_to_UserMode() commented out to ensure this is the case.
|
||||
*
|
||||
* *NOTE 4* The IntQueue common demo tasks test interrupt nesting and make use
|
||||
* of all the 8bit timers (as two cascaded 16bit units).
