STM32—IIC

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。
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

51单片机根据时序写的

void IIC_Start()
{
	scl = 0;
	scl = 1;
	sda = 1;
	_nop_();//延时大于4.7us
	sda = 0;
	_nop_();
}

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

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。

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;
}

数据发送的时序

void IIC_Send_Byte(char dataSend)
{
	int i = 0;
	for(i=0;i<8;i++){
	scl = 0;
	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;
	
	}
	
}

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，可以通过表格进行配置（一般选用页寻址模式：写入0x20再写入0x02）

内存管理
在这里插入图片描述

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

下面用的STM32F103HAL库

用到的库函数：

HAL_StatusTypeDef HAL_I2C_Mem_Write(I2C_HandleTypeDef *hi2c,
uint16_t DevAddress,
uint16_t MemAddress,
uint16_t MemAddSize,
uint8_t *pData,
uint16_t Size,
uint32_t Timeout)

参数一：I2C_HandleTypeDef *hi2c，I2C设备句柄
参数二：uint16_t DevAddress，目标器件的地址，七位地址必须左对齐
参数三：uint16_t MemAddress，目标器件的目标寄存器地址
参数四：uint16_t MemAddSize，目标器件内部寄存器地址数据长度
参数五：uint8_t *pData，待写的数据首地址
参数六：uint16_t Size，待写的数据长度
参数七：uint32_t Timeout，超时时间
返回值：HAL_StatusTypeDef，HAL状态（OK，busy，ERROR，TIMEOUT）

向OLED写命令的封装：

void Oled_Write_Cmd(uint8_t dataCmd)
{

 HAL_I2C_Mem_Write(&hi2c1, 0x78, 0x00, I2C_MEMADD_SIZE_8BIT,

 &dataCmd, 1, 0xff);
}

向OLED写数据的封装：

void Oled_Write_Data(uint8_t dataData)
{

 HAL_I2C_Mem_Write(&hi2c1, 0x78, 0x40, I2C_MEMADD_SIZE_8BIT,

 &dataData, 1, 0xff);
