【51单片机篇】IIC协议&OLED显示

一、IIC协议

（一）概述

IIC（集成电路总线）是由飞利浦公司发明的通讯总线，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。IIC的数据线只有一根，就是SDA，同一时间不管发送还是接收，只能有一个方向进行操作。

（二）构成

IIC串行总线一般有两根信号线，一根是双向的数据SDA，另一根是时钟线SCL，其中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。

（三）时序分析

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。

1.开始信号

时钟线处于高电平，数据线由高电平转为低电平。

2.结束信号

时钟线处于高电平，数据线由低电平转为高电平。

3.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。

（四）代码示例

IIC协议基本函数封装

#include "reg52.h"
#include <intrins.h>

sbit scl = P0^1;
sbit sda = P0^3;

void IIC_Start()
{
	sda = 1;
	scl = 1;
	_nop_();
	sda = 0;
}

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
		_nop_();//发送数据建立时间
		scl = 1;//scl拉高开始发送
		_nop_();
		scl = 0;//发送完毕，拉低
		_nop_();
		dataSend = dataSend << 1;
	}
}

void main()
{
	
}

二、OLED显示

（一）时序分析

写命令/数据编程步骤：

1. start()

2. 写入 b0111 1000 0x78

3. ACK

4. cotrol byte: (0)(0)000000 写入命令 (0)(1)000000写入数据

5. ACK

6. 写入指令/数据

7. ACK

8. STOP
