# AVR Software Framework: UC3 SPI Driver

Copyright © 2006-2008 Atmel Corporation

## Introduction

The Serial Peripheral Interface (SPI) circuit is a synchronous serial data link that provides communication with external devices in Master or Slave Mode. It also enables communication between processors if an external processor is connected to the system.

## SPI Driver

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

For an example about SPI access on a dataflash component, see the Dataflash AT45DBx example.

For an example about SPI access on an LCD component, see the LCD DIP204 example.

For an example about SPI access on a TOUCH component, see the TOUCH QT60168 example.
