摘　　要：视频数据传输接口SPI(Serial Peripheral Interface—串行外设接口)总线系统是一种同步串行外设接口,是Motorola首先在其MC68HCXX系列处理器上定义的。SPI接口主要应用在EEPROM,FLASH,实时时钟,AD转换器,还有数字信号处理器和数字信号解码器之间。本文基于ARM处理器为平台,介绍一种视频数据传输接口(SPI)的开发方法,实现设备的通讯。Video data transmission interface SPI(Serial Peripheral Interface)bus system is a kind of Synchronous Serial Peripheral Interfacewhich was firstly defined in MC68HCXX processor by Motorola.SPI is mainly used in EEPROM,FLASH,real-time clock,AD convertor andbetween digital signal processor and decoder.Based on ARM processor as a platform,this thesis aims to introduce a development approach ofvideo data transmission interface SPI in order to realize the communication of equipments.
