IIC 协议
1.1 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，速度约为10kb/s，IIC是一个多主从的串行总线(任意时刻只能有一个主机等特性)，又叫I2C，属于半双工同步传输类型的总线； 它仅使用两条线就能完成多机通讯，一条SCL时钟线，另外一条双向数据线SDA。 SDA和SCK在空闲的时候要处于高电平状态，所以需要通过电阻上拉
IIC总线标准模式下速度可以达到100Kb/s，快速模式下可以达到400Kb/s。IIC总线工作是按一定的协议来运行的。IIC是为了与低速设备通信而发明的，所以IIC的传输速率比不上SPI，IIC是支持多从机的，也就是一个IIC控制器下可以挂多个IIC从设备，这些不同的IIC从设备有不同的器件地址，这样IIC主控制器就可以通过IIC设备的器件地址访问指定的IIC设备了，一个IIC总线连接多个IIC设备如下图：![[STC89C52RC]基于IIC协议的OLED显示字符_第1张图片](http://img.e-com-net.com/image/info8/330533ae455c427e83623a6047d5dd26.jpg)
IIC总线标准模式下速度可以达到100Kb/s，快速模式下可以达到400Kb/s。IIC总线工作是按一定的协议来运行的。IIC是为了与低速设备通信而发明的，所以IIC的传输速率比不上SPI，IIC是支持多从机的，也就是一个IIC控制器下可以挂多个IIC从设备，这些不同的IIC从设备有不同的器件地址，这样IIC主控制器就可以通过IIC设备的器件地址访问指定的IIC设备了，一个IIC总线连接多个IIC设备如下图：
上图中SDA和SCL这两根线必须要接一个上接电阻，一般是4.7K。其余的IIC从器件都挂接到SDA和SCL这两根线上，这样就可以通过SDA和SCL这两根线来访问多个IIC设备。
通常我们为了方便把IIC设备分为主设备和从设备，基本上谁控制时钟线（即控制SCL的电平高低变换）谁就是主设备。
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 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 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
![[STC89C52RC]基于IIC协议的OLED显示字符_第2张图片](http://img.e-com-net.com/image/info8/81fce49c28394493a51a5eb70648d0ed.jpg)
分析虚线区间可得：要发送起始信号，首先SCL为高电平，SDA也为高电平，延时>4.7us，SDA被拉低，再延时>4.7us
void IIC_Start()
{
SCL = 0;//防止雪花屏
SDA = 1;
SCL = 1;
_nop_();
SDA = 0;
_nop_();
}终止信号
![[STC89C52RC]基于IIC协议的OLED显示字符_第3张图片](http://img.e-com-net.com/image/info8/13536301eb3d4229892dc318bba54074.jpg)
分析虚线区域可得 ：要发送终止信号，SCL为高电平，SDA为低电平，延时>4.7us后,SDA被拉高，延时>4.7us
void IIC_Stop()
{
SCL = 0;//防止雪花屏
SDA = 0;
SCL = 1;
_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(SDA置1)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。
![[STC89C52RC]基于IIC协议的OLED显示字符_第4张图片](http://img.e-com-net.com/image/info8/1f4f5e742a764ff894851c75e28123ee.jpg)
检查应答信号：首先再时钟脉冲9释放数据线即将SDA置1，SCL为低电平，延时几位秒拉高SCL，延时>4us，检测若SDA为低电平则为应答模式，SDA为高电平则为非应答模式
char IIC_ACK()
{
char flag;
SDA = 1;//就在时钟脉冲9期间释放数据线
SCL = 0;
_nop_();//约5us
SCL = 1;
_nop_();
flag = SDA;//检测到底是0应答模式还是1非应答模式
_nop_();
SCL = 0;
_nop_();
return flag;
}IIC发送数据分析
![[STC89C52RC]基于IIC协议的OLED显示字符_第5张图片](http://img.e-com-net.com/image/info8/08c4f2641f9e41809a2d2ca361ed4f3c.jpg)
根据上面发送数据的时序图分析可知，SDA状态变换的时候一定是SCL为低电平，拉低SCL将数据的最高位取出，延时几微秒后释放SCL开始传输,数据传输结束后，拉低SCL为下一位传输做准备
void IIC_SendByte(char tmp)
{
unsigned char i;
for(i=0;i<8;i++){
SCL = 0;//观察时序图可知，只有在SCL=0的时候SDA才能做出状态变换
SDA = tmp & 0x80;//取出最高位因为IIC是从高位传输，如果tem最高位为0，那么0&1=0，将0传入SDA
_nop_();//延时约5us
SCL = 1;//释放SCL，让数据传输
_nop_();
SCL = 0;//拉低SCL为下一位传输做准备
_nop_();
tmp = tmp << 1;//tmp左移一位，传输第二位
}
}IIC写模式配置
![[STC89C52RC]基于IIC协议的OLED显示字符_第6张图片](http://img.e-com-net.com/image/info8/7bcfd7c2e2184fa3aefbb88fe491ce8a.jpg)
写模式分为：写数据，写命令
由上图可知，第一个配置的是：Slave Address： Slave Address前6位是固定的，为011110 后两位为SA0,R/W# 查询数据手册：![[STC89C52RC]基于IIC协议的OLED显示字符_第7张图片](http://img.e-com-net.com/image/info8/55f50d5dbc1340899646346461fda7a0.jpg)
SA0主要是区分多个Oled挂在IIC上到底是哪一个，本次项目只有一个Oled，所以配置为0
R/W#:如果要配置为写模式，那么R/W#要配置为逻辑0
Slave Address 和 Control Byte之间有一个ACK!!!! Slave Address之前开有一个Start
第二个配置的是 Control Byte：
第一位为Co：有数据手册可知道，如果将Co配置成0，那么就是传输数据
第二位为D/C：将D/C配置成0，发送指令，配置成1，发送数据
void Oled_Write_Cmd(unsigned char cmd)
{
// IICStart
IIC_Start();
// Slave Address
IIC_SendByte(0x78);
// ACK
IIC_ACK();
// control byte data:(0)(1)000000 cmd:(0)(0)000000
IIC_SendByte(0x00);
// ACK
IIC_ACK();
//写入数据/指令
IIC_SendByte(cmd);
//ACK
IIC_ACK();
//STOP
IIC_Stop();
}
void Oled_Write_Data(unsigned char datas)
{
// IICStart
IIC_Start();
// Slave Address
IIC_SendByte(0x78);
// ACK
IIC_ACK();
// control byte data:(0)(1)000000 cmd:(0)(0)000000
IIC_SendByte(0x40);
// ACK
IIC_ACK();
//写入数据/指令
IIC_SendByte(datas);
//ACK
IIC_ACK();
//STOP
IIC_Stop();
}根据数据手册可以查得Oled初始化程序

Oled由三种点亮模式，页模式，水平模式，垂直模式
页模式：

水平模式：
![[STC89C52RC]基于IIC协议的OLED显示字符_第9张图片](http://img.e-com-net.com/image/info8/ec68fc98bb254c3bbb438c8d89d3e948.jpg)
垂直模式：
![[STC89C52RC]基于IIC协议的OLED显示字符_第10张图片](http://img.e-com-net.com/image/info8/99e6556b662a467bb20bbb0fa57f1160.jpg)

由上表可知，发送0x20选择配置Memory Addressing Mode，发送0x02就可以配置成页模式（不配置默认情况也是页模式），发送0x20，0x01配置垂直模式，发送0x20，0x00，配置水平模式

Oled_Write_Cmd(0x10););清屏
因为Oled会保留上一次得数据，所以每次显示可能会花屏，所以需要写一个清屏函数
void Oled_Clear()
{
unsigned int i,j;//用char也会出现雪花，因为char型的范围是-127 -- 128，for循环会到127的时候i++会越界
for(i=0;i<8;i++){
//PAGE0 --- PAGE7
Oled_Write_Cmd(0xB0+i);
//第0列
Oled_Write_Cmd(0x00);
Oled_Write_Cmd(0x10);
//0-127列依次写入0，写入数据自动偏移
for(j=0;j<128;j++){
Oled_Write_Data(0x00);//在PAGE0第一列写完后会自动跳到第二列，直到PAGE7第127列
