二线(I2C总线)串行数据传送接口设计

Two-Line (I2C BUS) SERIAL Data Transmission Interface

本文介绍了12C总线规范和利用EDA技术实现串行接口电路的设计方案．对串行接口电路中串行信 号的起始条件、停止条件及数据的地址位、读写位、应答位等12C总线规范中的细节部分进行了具体的描述,以 及用VHDL语言进行描述等．

The paper introduce the protocol of I2C BUS in detail and how to realize the serial interface circuit by taking advantage of EDA technology. It described the special part of I2C BUS protocol such as the start eondition,the stop condition, the data bit, address bit, read/write bit , response bit, and so on in VHDL language.
