模拟I^2C总线应用程序的设计

Design and Implementation for Simulated I^2C Bus Applied Program

在介绍I2 C总线的一般应用特性、硬件构成、I2 C总线数据传送的信号时序的基础上 ,给出了不带I2 C总线接口的单片机如何使用普通的I/O口来模拟I2 C总线接口进行数据传送 ,以及数据传送的通用子程序。

After concisely introducing the general applied properties, hardware construction of I 2C bus and its sequences for the sent signals, this paper presents how a microcomputer using a common I/O interface realizes the analog I 2C bus data transmission and its general subprogram for the data transmission.
