计算机与I^2C总线间的接口与编程

The Interface and Programming between Computer and I 2C bus

Ｉ２Ｃ总线已成为集成电路器件间数据通信的一种协议，具有简易方便、智能快捷的特点。本文在介绍其工作原理的基础上设计了一种计算机与Ｉ２Ｃ总线间的接口电路并对软件编程作了说明。

The I 2C bus which is very intelligent and facile has become a protocol of the data transfer between ICs. The principle of I 2C bus is described in this paper. An interface circuit between a computer and I 2C bus is designed and some advices of software related the protocol is discussed in the paper.
