# AVR UC3 Series Software Framework: USART Driver

Copyright © 2007 Atmel Corporation

## Introduction

This driver will let you communicate through serial ports of all AVR®32 AT32UC3 devices.

The USART driver philosophy of usage is:
- Configure one (or several) USART in the wanted mode [usart_init_xxxxx]
- Send or receive data on the configured USART, [usart_putchar, usart_getchar, usart_write_line, ...]

## USART Driver

The driver is composed of usart.c and usart.h.

One example is currently available:

- Simple access to a serial port
