IIC协议
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
构成
IIC串行总线一般有两根信号线，一根是双向的数据线SDA，另一根是时钟线SCL，其时钟信号是由主控器件产生。所有接到IIC总线设备上的串行数据SDA都接到总线的SDA上，各设备的时钟线SCL接到总线的SCL上。对于并联在一条总线上的每个IC都有唯一的地址。
IIC总线在传输数据的过程中一共有三种类型信号，分别为：开始信号、结束信号和应答信号。
//起始位，停止位，数据位，速度
这些信号中，起始信号是必需的，结束信号和应答信号
起始和终止信号时序图:
应答信号
发送器每发送一个字节（8个bit），就在时钟脉冲9期间释放数据线，由接收器反馈一个应答信号。
应答信号为低电平时，规定为有效应答位（ACK，简称应答位），表示接收器已经成功地接收了该字
节；
应答信号为高电平时，规定为非应答位（NACK），一般表示接收器接收该字节没有成功
应答信号时序图：
