* Instead of the normal single demo application, the PIC18F demo is split
* into several smaller programs of which this is the sixth. This enables the
* demo's to be executed on the RAM limited PIC-devices.
*
* The Demo6 project is configured for a PIC18F4620 device. Main.c starts 4
* tasks (including the idle task). See the indicated files in the demo/common
* directory for more information.
*
* demo/common/minimal/comtest.c: Creates 2 tasks
* ATTENTION: Comtest needs a loopback-connector on the serial port.
*
* 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.
*
* http://www.FreeRTOS.org contains important information on the use of the
* wizC PIC18F port.
