Title: epwmdemoTarget: PIC18F458Description:    A project to demonstrate the extended PWM ability of the    PIC18F4x8 devices.Controls:    Two DIP switches are used in this project. The first selects    which PWM mode the device will operate in. For example, single    output, half-bridge, full-bridge.    The second DIP switch determines that the active output level    for the PWM output pairs.    PWM period and duty are modified using the potentiometers.    The output of the PWM pairs is displayed on the logic analyser    and on the LED display.    The current mode of operation is readable in the serial IO window.Connections to the PIC18F458:    DIP switch [1:2] -> PORTC [0:1]    DIP switch [1:2] -> PORTC [3:2] (reverse connect)    Potentiometer 1  -> PORTA0 (period)    Potentiometer 2  -> PORTA1 (duty cycle)    Analyser [0:3]   -> PORTD [4:7]    LED [1:4]        -> PORTD [4:7]
