AVR UC3 Series Software Framework: 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.
