/*
* This file contains a demo created to execute on the Rowley Associates
* LPC2138 CrossFire development board.
*
* main() creates all the demo application tasks, then starts the scheduler.
* The WEB documentation provides more details of the standard demo application
* tasks.
*
* Main.c also creates a task called "Check". This only executes every few
* seconds but has a high priority so is guaranteed to get processor time.
* Its function is to check that all the other tasks are still operational.
* Each standard demo task maintains a unique count that is incremented each
* time the task successfully completes its function. Should any error occur
* within such a task the count is permanently halted. The check task inspects
* the count of each task to ensure it has changed since the last time the
* check task executed. If all the count variables have changed all the tasks
* are still executing error free, and the check task writes "PASS" to the
* CrossStudio terminal IO window. Should any task contain an error at any time
* the error is latched and "FAIL" written to the terminal IO window.
*
* Finally, main() sets up an interrupt service routine and task to handle
* pushes of the button that is built into the CrossFire board. When the button
* is pushed the ISR wakes the button task - which generates a table of task
* status information which is also displayed on the terminal IO window.
*
* A print task is defined to ensure exclusive and consistent access to the
* terminal IO. This is the only task that is allowed to access the terminal.
* The check and button task therefore do not access the terminal directly but
* instead pass a pointer to the message they wish to display to the print task.
