USART example 2 for STK600-RCUC3L4 Documentation

Introduction

This demo application is a simple example demonstrating the basic use of the AVR32 UC3 USART driver on a range of Atmel hardware.

Example's operating mode:

1. A message is displayed on the PC terminal ("Hello, this is AT32UC3 saying hello! (press enter)")
2. You may then type any character other than CR(Carriage Return) and it will be echoed back to the PC terminal.
3. If you type a CR, "'CRLF'Goodbye." is echoed back to the PC terminal and the application ends.
