/*
* Creates all the demo application tasks, then starts the scheduler. The WEB
* documentation provides more details of the standard demo application tasks.
* In addition to the standard demo tasks, the following tasks and tests are
* defined and/or created within this file:
*
* "LCD" task - the LCD task is a 'gatekeeper' task. It is the only task that
* is permitted to access the display directly. Other tasks wishing to write a
* message to the LCD send the message on a queue to the LCD task instead of
* accessing the LCD themselves. The LCD task just blocks on the queue waiting
* for messages - waking and displaying the messages as they arrive.
*
* "Check" task - This only executes every three seconds but has the highest
* priority so is guaranteed to get processor time. Its main function is to
* check that all the standard demo tasks are still operational. Should any
* unexpected behaviour within a demo task be discovered the check task will
* write an error to the LCD (via the LCD task). If all the demo tasks are
* executing with their expected behaviour then the check task instead writes
* a count of the number of times the high frequency interrupt has incremented
* ulHighFrequencyTimerInterrupts - which is one in every 20,000 interrupts.
*
* "Register test" tasks - These tasks are used in part to test the kernel port.
* They set each processor register to a known value, then check that the
* register still contains that value. Each of the tasks sets the registers
* to different values, and will get swapping in and out between setting and
* then subsequently checking the register values. Discovery of an incorrect
* value would be indicative of an error in the task switching mechanism.
*
* By way of demonstration, the demo application defines
* configMAX_SYSCALL_INTERRUPT_PRIORITY to be 3, configKERNEL_INTERRUPT_PRIORITY
* to be 1, and all other interrupts as follows:
*
* + The UART is allocated a priority of 2. This means it can interrupt the
* RTOS tick, and can also safely use queues.
* + Two timers are configured to generate interrupts just to test the nesting
* and queue access mechanisms. These timers are allocated priorities 2 and 3
* respectively. Even though they both access the same two queues, the
* priority 3 interrupt can safely interrupt the priority 2 interrupt. Both
* can interrupt the RTOS tick.
* + Finally a high frequency timer interrupt is configured to use priority 4 -
* therefore kernel activity will never prevent the high frequency timer from
* executing immediately that the interrupt is raised (within the limitations
* of the hardware itself). It would not be safe to access a queue from this
* interrupt as it is above configMAX_SYSCALL_INTERRUPT_PRIORITY.
*
* See the online documentation for this demo for more information on interrupt
* usage.
