一、IIC协议简介

IIC通信协议(Inter—-Integrted Circuit)是由Phiips飞利浦公司开发的，由于他引脚少，硬件实现简单，可拓展性强，不需要USART,CAN通讯协议的外部收发设备，现在被广泛使用在系统内多个集成电路IC（芯片）间的通讯，IIC使用半双工通讯，半双工允许数据在两个方向上传输，但是同一时间数据只能在一个方向上传输，实际上是切换的单工。

二、IIC总线系统结构

IIC是一个支持多设备的总线。”总线“是指多个设备共用的信号线，在一个IIC通讯总线中，可连接多个IIC通讯设备，支持多个通讯主机及多个通讯从机。

一个IIC总线只使用两条总线线路，一条双向串行数据线(SDA)，一条串行时钟线(SCL)。数据线即用来表示数据，时钟线用于数据收发同步。

每个连接到总线的设备都有一个独立的地址，主机可以利用这个地址进行不同设备直接访问。

三、IIC总线物理层特点

总线通过上拉电阻接到电源

当IIC设备空闲时，会输出高阻态，而当所有设备都空闲时，都输出高阻态，由上拉电阻把总线拉成高电平

多个主机同时使用总线时，为了防止数据冲突，会利用仲裁方式决定哪个设备占用总线

具有三种传输模式：标准模式传输速率为100kbit/s,快速模式为400kbit/s，高速模式下可达3.4M/s，但目前大多IIC设备尚不支持高速模式，主要应用低速模式。

四、软/硬件IIC总线

硬件IIC：对应芯片上的IIC外设，由相对应的IIC驱动电路，其所使用的IIC管脚也是专用的

软件IIC：一般是用GPIO管脚，用软件控制管脚状态以及模拟IIC通信波形

两者区别：硬件IIC的效率要远高于软件的，而软件IIC不受引脚限制，接口比较灵活。软件IIC 是通过GPIO,软件模拟寄存器的工作方式，而硬件IIC是直接调用内部寄存器进行配置。如果要从具体硬件上来看，可以去看下芯片手册，因为固件IIC的端口是固定的，所以会有所区别。

硬件IIC用法复杂，模拟IIC流程更加清楚，硬件IIC速度比模拟快，并且可以用DMA，模拟IIC可以在任何管脚上，硬件IIC在固定管脚上。

五、IIC总线协议层

IIC的协议定义了通讯的起始和停止信号、数据有效性、响应、仲裁、时钟同步和地址广播等环节。

IIC基本读写过程：

1.主机写数据到从机

S：数据由主机传输至从机

SLAVE ADDRESS：从机地址

起始信号产生后，所有从机就开始紧接下来广播的从机地址信号。IIC总线，每个设备的地址都是唯一的，当主机广播的地址与某个设备的地址相同时，这个设备就被选中了，没被选中的设备将会忽略之后的数据信号。根据IIC协议，这个从机地址可以是7位或者10位。

R/W:地址位之后，传输方向选择位，为0：表示数据传输方向是由主机传输到从机，即主机向从机写数据，为1：表示数据传输方向是由从机传输到主机，即从机向主机写数据。从机接收传输方向选择位后，主机或从机会返回一个应答A(ACK)或非应答A/A(NACK)信号，只有接收到应答信号后，主机才能继续发送或者接收数据。

P:数据传输结束

2.主机读数据到从机

读数据：

配置方向传输位为“读数据”方向。

广播完地址后，接收到应答信号后，从机开始向主机返回数据(DATA),数据包大小也为8位，从机没发送完一个数，都会等待主机信号(ACK)，重复这个过程，可以返回N个数据，N没有限制大小，当主机希望停止接收数据时，就向从机返回一个非应答信号(NCAK)，则从机自动停止传输数据。

3、通讯复合模式

复合格式，该传输过程有两次起始信号(S)

在第一次传输过程中，主机通过SLAVE_ADDRESS寻找到从设备后，发送一段“数据”，这段数据通常用于表示从设备内部的寄存器或存储器地址；

第二次传输中，对该地址的内容进行读或者写，也就是说，第一次通讯时告诉从机读写地址，第二次则是读写的实际内容。

六、IIC通讯结构

1.空闲状态：

IIC总线的SDA和SCL两条信号线同时处于高电平时，规定为总线的空闲状态。在空闲状态期间，输出场效应管均处在截止状态，即释放总线，由两条信号线各自的上拉电阻把电平拉高。

２.起始信号：

当SCL为高电平期间，SDA由高到低的跳变；启动信号时一种电平跳变时序信号，而不是一个电平信号。

３.停止信号：

当SCL为高电平期间，SDA由低到高的跳变；停止信号也是一种高电平跳变时序信号，而不是一个电平信号。

注：起始信号和停止信号一般由主机产生

4.应答信号：

发送器每发送一个字节，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受了该字节；

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；

对于反馈有效应答位ACK的要求是，接收器在第九个时钟脉冲之前的低电平期间将SDA线拉低，并且确保在该时钟的高电平期间为稳定的低电平

如果接收器是主控器，则在它收到在最后一个字节后，发送一个NACK信号，以通知被控发送器数据发送，并释放SDA线，以便主控接收器发送一个停止信号P；

５.数据的有效性：

IIC总线进行数据传输时，时钟信号为高电平期间，数据线上的数据必须保持稳定，只有在时钟线上的信号为低电平期间，数据线上的高电平或低电平状态才允许变化，SDA数据线在SCL的每个时钟周期传输一位数据；

数据在SCL的上升沿到来之前就需准备好，并在下降沿到来之前必须稳定

6.数据传输

在IIC总线上传送的每一位数据都有一个时钟脉冲相对应（或者同步控制），即在SCL串行时钟的配合下，SDA上逐位地串行传送每一位数据，数据位的传输是边沿触发。

七、STM32的IIC特性及其架构

1.软件模拟协议

使用CPU直接控制通讯引脚的电平，产生出符合通讯协议标准的逻辑

2.硬件实现协议

由STM32的IIC片上外设专用负责实现IIC通讯协议，只要配置好该外设，它就会自动根据协议要求产生通讯信号，收发数据并缓存起来，CPU只要检测该外设的状态和访问数据寄存器，就能完成数据收发。这种由硬件外设处理IIC协议的方式减轻了CPU的工作，且使软件设计更加简单。

注：STM32的IIC外设可用作通讯的主机及从机，支持100Kbits/s和400Kbits/s的速率，支持7位、10位设备地址，支持DMA数据传输，并具有数据校验功能。

八、STM32的IIC架构

通讯引脚

时钟控制逻辑

数据控制逻辑

整体控制逻辑

1.通信引脚

STM32芯片有多个IIC外设，它们的IIC通讯信号引出到不同的GPIＯ引脚上，使用时必须配置这些指定的引脚

2.时钟控制逻辑

1)控制逻辑简介：

SCL线的时钟信号，由IIC接口根据时钟控制寄存器(CCR)控制，控制的参数主要为时钟频率

可选择的IIC通讯的“标准/快速模式”，这两个模式分别对应100/400Kbits/s的通讯速率

在快速模式下可选择SCL时钟的占空比，可选T(low)/T(high)=2或T(low)/T(high)=16/9模式

CCR寄存器中12位的配置因子CCR，它与IIC外设的输入时钟源共同作用，产生SCL时钟，STM32的IIC外设输入时钟源为PCLKl1

2）计算时钟频率：

标准模式：

Thigh = CCR*Tpclk1

Tlow = CCR*Tpclk1

快速模式中 T low/T high =2 时:

Thigh = CCR*Tpclk1

Tlow = 2*CCR *Tpclk1

快速模式中 T low/T high =2 时:

Thigh = 9 * CCR * Tpclk1

Tlow = 16 * CCR *Tpclk1

如：PCLK1=36Mhz,想要配置400Kbits/s，方法：

PCLK时钟周期：TPCLK1=1/36 000 000

目标SCL时钟周期：TSCL=1/400 000

SCL时钟周期内的高电平时间：Thigh=TSCL/3

SCL周期时钟内的低电平时间：Tlow=2*TSCL/3

计算CCR的值 ： CCR＝Thigh/Tpclk1=30

计算出来的值写入到寄存器即可

3.数据控制逻辑

IIC的SDA信号主要连接到数据移位寄存器上，数据移位寄存器的数据来源及目标是数据寄存器（DR）、地址寄存器(OAR)、PEC寄存器以及SDA数据线

当向外发送数据的时候，数据移位寄存器以“数据寄存器”为数据源，把数据一位一位地通过SDA信号线发送出去

当从外部接收数据的时候，数据移位寄存器把SDA信号线采样的数据一位一位地存储到“数据寄存器”中

九、STM32的IIC的通信过程

使用IIC外设通讯时，在通讯的不同阶段它会对“状态寄存器（SR1和SR2）”的不同数据位写入参数，通过读取这些寄存器标志来了解通讯状态

主发送器：

控制产生起始信号(S)，当发生起始信号后，它产生事件” EV5〞,并会
对SR1寄存器的 SB 位置1，表示起始信号己经发生。

发生设备地址井等待应答信号，若有从机应答，则产生时间 EV6及
EV8这时SR1寄存器的 ADDR位及TXE位被
置1，ADDR位1表示地址己经发送，TEX表示数据寄存器为空。

十、STM32的IIC结构体

typedef struct
{

uint32_t I2C_ClockSpeed; //设置SCL时钟频率，此值要低于400 000

uint16_t I2C_Mode; //指定工作模式，可选IIC模式及SMBUS模式

uint16_t I2C_DutyCycle;//时钟占空比，可选low/high = 2:0或16:9

uint16_t I2C_Own_Address1;//自身的11C设备地址

uint16_t I2C_Ack;//使能或者关闭响应，一般是使能

uint16_t I2C_AcknowledgedAddress;//指定地址长度，可为7或10

}12C InitTypeDef;

1. uint32_t I2C_ClockSpeed; //设置SCL时钟频率，此值要低于400 000

设置IIC的传输速率，在调用初始化函数时，函数会根据我输入的数值经过运算后把时钟因子写入到IIC的时钟控制寄存器CCR，而我们写入的这个参数值不得高于Khz

实际上由于CCR寄存器不能写入小数类型的时钟因子，影响到SCL的实际频率可能会低于本成员设置的参数值，这时除了通讯会稍微慢点以外，不会对IIC的标准通讯造成其他影响。

2.uint16_t I2C_Mode;//指定工作模式，可选IIC模式及SMBUS模式

选择IIC的使用方式。有IIC模式(I2C_Mode_IIC)和SMBus主、从模式(IIC_Mode_SMBusHost、IIC_Mode_SMBusDeceive)

IIC不需要在此处区分主从模式，直接设置IIC_Mode_IIC即可

3.uint16_t I2C_DutyCycle;//时钟占空比，可选low/high = 2:0或16:9

设置IICSCL线时钟的占空比。该配置有两个选择，分别为低电平时间比高电平时间2:1(IIC_DutyCycle_2)和16:9(IIC_DutyCycle_16_9)

其实这两个模式的比例差别不大，一般要求都不会如此严格，这里随便选就可以。

4.uint16_t I2C_Own_Address1;//自身的11C设备地址

配置STM32的IIC设备自己的地址，每个连接到IIC总线上的设备都有一个自己的地址，作为主机也不例外。地址可以设置为7位或10位(受下面IIC_AcknowledgeAddress成员决定)，只要该地址是IIC总线上唯一的即可

STM32的IIC外设可同时使用两个地址，即同时对两个地址作出响应，这个结构体成员IIC_OwnAddress1配置的是默认的，OAR1寄存器存储的地址，若需要设置第二个地址寄存器OAR2,可使用IIC_OwnAddress2Config函数来配置，OAR2不支持10位地址。

5.uint16_t I2C_Ack;//使能或者关闭响应，一般是使能

配置IIC应答是否使能，设置使能则可以发送响应信号，一般配置为允许应答(IIC_Ack_Enable)，这是绝大多数遵循IIC标准的设备的通讯要求，改为禁止应答(IIC_Ack_Disable)往往会导致通讯错误

6. uint16_t I2C_AcknowledgedAddress;//指定地址长度，可为7或10

选择IIC的寻址模式是7位或者是10位地址，这需要根据实际连接到IIC总线上的设备地址进行选择，这个成员的配置也影响到IIC_OwnAddress成员，只有这里设置成10位模式时，IIC_OwnAddress1才支持10位地址

配置完这些结构体成员的值，调用库函数IIC_Init就可以把结构体的配置写入对应的寄存器中。

十一、OLED屏幕

OLED即有机发光管(Organic Light-Emitting Diode,OLED)，OLED显示技术具有自发光、广视角、几乎无穷高的对比度、较低功耗、极高优点反应速度、可用于挠曲性面板、使用温度范围广、构造及制造简单等优点
被认为是下一代的平面显示屏新兴应用技术

OLED显示和传统的LCD显示不同，其可以自发光，所以不需要背光灯，这使得OLED显示屏相对于LCD显示屏尺寸更薄，同时显示效果更优

常用的OLED屏幕有蓝色、黄色、白色等几种，屏的大小为0.96寸，像素点为128*64，所以我们称为0.96oled屏或者12864屏

模块尺寸：23.7*23.8mm

电源电压：3.3v-5.5v

驱动芯片：SSD1306

测试平台：提供k60/k10,9s12xs128,51,stm32,stm8等单片机

十二、OLED屏幕接线

GND——OLED显示模块电源地

VCC——OLED显示模块电源正（3.3v/5v）

SCL——OLED显示模块IIC总线时钟信号

SDA——OLED显示模块IIC总线数据信号

十三、OLED屏幕显存及其原理

如图，OLED屏幕显存有64行乘128列，一共分为8页，一页8行，128列。

OLED本身是没有显存的，他的显存是依赖SSD1306提供的，而SSD1306提供一块显存

SSD1306显存总共为128*64bit大小，SSD1306将这些显存分成了8页，每页包含128字节。

STM32内部建立一个缓存（共128*8个字节），每次修改的时候，只是修改STM32上的缓存(实际上就是SRAM)，修改完后一次性把STM32上的缓存数据写入到OLED的GRAM（但对于SRAM很小的单片机就比较麻烦）

十四、OLED屏幕常用指令

0x81:设置对比度。包含两个字节，第一个0x81为命令，随后法是的一个字节要设置这个对比度，值越大屏幕越亮

命令0xAE/0xAF:0xAE为关闭显示命令，0xAF为开启显示命令

0x8D:包含两个字节，第一个为命令字，第二个为设置值，第二个字节的BIT2(A2)表示电荷泵的开关状态，该位为1开启电荷泵，为0则关闭。模块初始化的时候，这个必须要开启，否则看不到屏幕显示。

命令0xB0~B7:用于设置页地址，其低三位的值对应GRAM页地址

命令0x00~0x0F:用于设置显示时的起始列地址低四位

命令0x10~0x1F:用于设置显示时的起始列地址高四位

十五、OLED屏幕字模软件的使用

OLED打点方式：

OLED点阵的点亮方式，举个显示“P”的例子，最左边为最高位P7

可以看出，想要显示“P”，首先写入0x1f，则显示一个竖杠，之后控制器自动水平移动到下一列

再写入0x05，则出现两个小横杆，这两个横杆就是0x05中0000 0101中两个1所处的位置，写完第二列后，控制器自动跳到第三列

再写入0x07，第四列写入0x00后，P就显示出来了，这也说明，即使你只想在第一列的最上端显示一个小数点，即写入0x01

即你不能一次性控制一个点阵，只能一次性控制八位点阵，即一列点阵，这决定了字模选择的取模方式为“列行式”

字模软件使用：

十六、IIC硬件通讯

主发送器：起始信号——EV5——发送器件地址——EV6——发送寄存器地址——EV8——发送数据——EV8——停止信号
