8051单片机系统I^2C总线接口设计与实现

Design and realization of I^2C bus interface in 8051 single chip microcomputer system

介绍了I2C总线技术标准,结合8051单片机与24LC02B芯片之间组成的I2C总线,给出了硬件连接设计,并用Keil C51给出了8051在总线上读写数据过程的软件代码,阐明了8051单片机I2C总线接口的实现方法.

This paper firstly introduced I2C bus technology criterion.Secondly,in order to introduce realization of I2C bus interface in 8051 single chip microcomputer,we utilized I2C bus between 8051 single chip microcomputer and 24LC02B chip.We presented hardware connection design,then presented software code realization of 8051 in the course of reading and writing data process in I2C bus based on Keil C51.
