/*
* Instead of the normal single demo application, the PIC18F demo is split
* into several smaller programs of which this is the first. This enables the
* demo's to be executed on the RAM limited PIC-devices.
*
* The Demo1 project is configured for a PIC18F4620 device. Main.c starts 9
* tasks (including the idle task).
* This first demo is included to do a quick check on the FreeRTOS
* installation. It is also included to demonstrate a minimal project-setup
* to use FreeRTOS in a wizC environment.
*
* Eight independant tasks are created. All tasks share the same taskcode.
* Each task blinks a different led on portB. The blinkrate for each task
* is different, but chosen in such a way that portB will show a binary
* counter pattern. All blinkrates are derived from a single master-rate.
* By default, this masterrate is set to 100 milliseconds. Although such
* a low value will make it almost impossible to see some of the leds
* actually blink, it is a good value when using the wizC-simulator.
* When testing on a real chip, changing the value to eg. 500 milliseconds
* would be appropiate.
