摘要
介绍了基于PC机打印口的I2C总线接口电路,以及利用该电路构成的A/D接口电路,并给出当PC机为唯一主控器件时利用I2C总线控制A/D转换芯片SAA7113H工作的基本原理和功能模块,本接口电路可以用来连接1个或多个基于I2C总线的器件。
The paper introduces the interface circuit of I^2C bus based on LPT of the PC , and theA/D interface circuit composed module of SAA7113 H controlled I^2C bus. by this circuit. It also gives out the basic operation principle and the function by I^2C bus. The interface circuit can link one or multiple devices based on
