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。

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协议

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
起始信号
终止信号

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。

数据发送的时序

sbit scl = P0^1;
sbit sda = P0^3;
void IIC_Start()
{sda = 1;scl = 1;_nop_();sda = 0;_nop_();
}
void IIC_Stop()
{sda = 0;scl = 1;_nop_();sda = 1;_nop_();
}
char IIC_ACK()
{char flag;sda = 1;//就在时钟脉冲9期间释放数据线_nop_();scl = 1;_nop_();flag = sda;_nop_();scl = 0;_nop_();return flag;
}
void IIC_Send_Byte(char dataSend)
{int i;for(i = 0;i<8;i++){scl = 0;//scl拉低，让sda做好数据准备sda = dataSend & 0x80;//1000 0000获得dataSend的最高位，给sda_nop_();//发送数据建立时间scl = 1;//scl拉高开始发送_nop_();//数据发送时间scl = 0;//发送完毕拉低_nop_();//dataSend = dataSend << 1;}
}

前面四步完成以后，即可向设备写入指令/数据

写入指令：

如上图：

Slave Address ->从机地址

start

0111 10（）（）（后面两位为用户自己配置）**

看这一小块，后面两个位代表SA0和R/W#

SA0:1、0均可配置，一般用于区分两个不同设备第一个括号姑且让它为0

R/W#：0代表配置为写入模式第二个括号为0

2.设置为写入 0111 1000->0x78

ACK

control byte xx000000

co:“0”表示此后只接数据字节

D/C：“0”代表发送命令；“1”代表发送数据

发送命令：0000 0000 （0x00）

发送数据：0100 0000 （0x40）

ACK

写入数据/命令

ACK

stop

OLED的寻址模式

如何显示一个点？
有三种，分别位页地址模式，水平地址模式和垂直地址模式，可以通过一下表格进行配置内存管理
内存管理

页地址模式

水平地址模式

垂直地址模式

列地址选择

如果写入0x08（b00001000）会显示什么呢
一个字节负责一个Page的一列显示
