Title: iodemo

Target: PIC18C858

Description: A sample project file to be used with HI-TIDE, to demonstrate the 
    device's input/output capabilities. All I/O ports are used in this
    demonstration. The output of Ports A,C,D,E,F,G,H,J & K can be observed via
    the LED panels connected to each.

Controls:
    The IO ports can be configured with any input/output pin configuration. This
    is done by entering the configuration on the blue DIP switch (ON=input, 
    OFF=output). This input/output configuration can be assigned to a port by
    pressing the pushbutton associated with that port.

    When any pin of a port is set in output mode, the pin will participate in
    displaying a test pattern that is generated in software. If any particular pin
    is configured as input, that pin will read the value from the corresponding 
    pin on the blue DIP switch.

Interrupts:
    This project only uses the change on PORTB interrupt. PORTB is wired to
    each of the 8 pushbuttons that are used to update the direction setting
    for each port.

Connections to the PIC18C858:
	LED(red1) [1:7] -> PORTA [0:6]
	pushbutton 1 -> PORTB4
	LED(red2) [1:8] -> PORTC [0:7]
