摘　　要：随着计算机技术的发展,I2C总线的应用越来越广泛。I2C是一种简单、双向的二线制同步串行总线,它只需要两根线———串行数据线和串行时钟线就可以在总线与连接器件之间进行数据传送。在介绍了它的工作原理和特点的基础上,阐述了运用C语言模拟I2C总线的程序设计方法,并以AT24C64为例介绍了它与非I2C总线单片机89C2051之间接口的软硬件设计。With the development of the computer technology,the Integrated Circuit bus has a deeper use.Integrated Circuit bus is a kind of two-line synchronization serial bus in the application of the single chip processor.It is bi-directional and simple in a application.Only using the two lines:synchronization serial bus and synchronization clock bus,which can Inter Integrated Circuit bus transfer data between the Inter Integrated Circuit bus and parts of the apparatuses.Introduced the working principle and the peculiarities of the Inter Integrated Circuit bus.On the basis of the working principle and the peculiarities,gave out the method of simulation Inter Ingegrated Circuit bus by using software C language.And as AT24C64 for an example,also introduced the designing method of the hardward and software on data transfer between Inter Integrated Circuit bus and the non Inter Integrated Circuit processor:single chip processor 89C2051.
