// WL Encore II Example Project
//
// Description: This is a simple project that is targeted at the CY7C603xx
// part.  The functionality is quite simple.  A two channel A/D converter is 
// setup using the ADC10 User Module.  The ADC alternates between channels 
// whose source is the Potentiometers on the board. The resultant output of
// the ADC is used to set the duty of the PWM outputs.  The PWM outputs are
// connected to two of the LEDs on the board.  The application also scans 
// the two push buttons and reflects their state on the two other LEDs.
//
// Hardware: This project can be run on the CYxxxx Wireless Encore II Evaluation
// board with the connections shown below.  
//
// Wireless Encore II Eval Connections:
//       port1_pin2 -> LED1
//       port1_pin3 -> LED2
//       port1_pin4 -> LED3
//       port1_pin5 -> LED4
//       port0_pin1 -> VR1
//       port0_pin3 -> VR2
//       port0_pin4 -> SW1
//       port0_pin5 -> SW2
