USB CDC-ACM example

Example functionality:
  Configures the device as an USB-UART adaptor. After loading the project
  executable, connect a USB cable from CN2 to a host PC. CN1 can also be
  connected for debug messages.

    1. LED0 should turn on once enumeration is complete.
    2. Connect another UART device to communicate with to UART1
       - (TX = P2.1, RX = P2.0).
    3. Open a terminal program for the MAXIM USB-UART adaptor
       COM port to send/receive data with another UART device.

Note: The auxiliary UART1 connection is optional. The characters
      received from the PC will be sent back as an echo.

Note: For a Windows PC the driver is the .inf file in the driver
      folder.

Jumper Configuration:
  No jumper configuration is required for the ADC Demo program.
