* Instead of the normal single demo application, the PIC18F demo is split
* into several smaller programs of which this is the seventh. This enables the
* demo's to be executed on the RAM limited PIC-devices.
*
* The Demo7 project is configured for a PIC18F4620 device. Main.c starts 10
* tasks (including the idle task). See the indicated files in the demo/common
* directory for more information.
*
* demo/common/minimal/flash.c: Creates 3 tasks
* demo/common/minimal/death.c: Creates 1 controltask and
* creates/deletes 4 suicidaltasks
*
* Main.c also creates a check task. This periodically checks that all the
* other tasks are still running and have not experienced any unexpected
* results. If all the other tasks are executing correctly an LED is flashed
* once every mainCHECK_PERIOD milliseconds. If any of the tasks have not
* executed, or report an error, the frequency of the LED flash will increase
* to mainERROR_FLASH_RATE.
*
* On entry to main an 'X' is transmitted. Monitoring the serial port using a
* dumb terminal allows for verification that the device is not continuously
* being reset (no more than one 'X' should be transmitted).
*
* http://www.FreeRTOS.org contains important information on the use of the
* wizC PIC18F port.
