1、IIC协议
1.1 IIC协议概述
IIC全称Inter-Integrated Circuit (集成电路总线)是由PHILIPS公司在80年代开发的两线式串行总线,用于连接微控制器及其外围设备。IIC属于半双工同步通信方式
特点:
简单性和有效性。
由于接口直接在组件之上,因此IIC总线占用的空间非常小,减少了电路板的空间和芯片管脚的数量,降低了互联成本。总线的长度可高达25英尺,并且能够以10Kbps的最大传输速率支持40个组件
多主控(multimastering)
其中任何能够进行发送和接收的设备都可以成为主总线。一个主控能够控制信号的传输和时钟频率。当然,在任何时间点上只能有一个主控。
