Description: I2C（Inter－Integrated Circuit）总线是由PHILIPS公司开发的两线式串行总线，用于连接微控制器及其外围设备。是微电子通信控制领域广泛采用的一种总线标准。它是同步通信的一种特殊形式，具有接口线少，控制方式简单，器件封装形式小，通信速率较高等优点。I2C 总线支持任何IC 生产过程(CMOS、双极性）。通过串行数据（SDA）线和串行时钟 （SCL）线在连接到总线的器件间传递信息。每个器件都有一个唯一的地址识别（无论是微控制器——MCU、LCD 驱动器、存储器或键盘接口），而且都可以作为一个发送器或接收器（由器件的功能决定）。LCD 驱动器只能作为接收器，而存储器则既可以接收又可以发送数据。除了发送器和接收器外，器件在执行数据传输时也可以被看作是主机或从机（见表1）。主机是初始化总线的数据传输并产生允许传输的时钟信号的器件。此时，任何被寻址的器件都被认为是从机。
