一、简单介绍

1.1   OLED

有机发光二极管（英语：Organic Light-Emitting Diode，缩写：OLED）又称有机电激发光显示（英语：Organic Electroluminescence Display，缩写：OELD）、有机发光半导体，OLED技术最早于1950年代和1960年代由法国人和美国人研制，其后由美国柯达及英国剑桥大学加以演进，日本SONY及韩国三星和LG等公司于21世纪开始量产，现在的市场都趋近于OLED但是在寿命上比LCD短。[来源请求]

OLED（有机发光二极管）与TFT-LCD（薄膜晶体管液晶显示器）为不同类型的产品，OLED具有自发光性、广视角、高对比、低耗电、高反应速率、全彩化及制程简单等优点，但相对的在大面板价格、技术选择性 、寿命、分辨率、色彩还原方面便无法与TFT-LCD匹敌，有机发光二极管显示器可分单色、多彩及全彩等种类，而其中以全彩制作技术最为困难。

OLED显示器依驱动方式的不同又可分为被动式（Passive Matrix，PMOLED）与主动式（Active Matrix，AMOLED）。

笔者使用的oled如上图，四针脚I2C协议，主控为SSD1306。

规格为0.96寸，分辨率为128*64

1.2   I2C协议

I²C（Inter-Integrated Circuit）字面上的意思是集成电路之间，它其实是I²C Bus简称，所以中文应该叫集成电路总线，它是一种串行通信总线，使用多主从架构，由飞利浦公司在1980年代为了让主板、嵌入式系统或手机用以连接低速周边设备而发展。I²C的正确读法为“I平方C”（"I-squared-C"），而“I二C”（"I-two-C"）则是另一种错误但被广泛使用的读法。自2006年10月1日起，使用I²C协议已经不需要支付专利费，但制造商仍然需要付费以获取I²C从属设备地址[1]。

I²C的参考设计使用一个7比特长度的地址空间但保留了16个地址，所以在一组总线最多可和112个节点通信[a]。常见的I²C总线依传输速率的不同而有不同的模式：标准模式（100 kbit/s）、低速模式（10 kbit/s），但时钟频率可被允许下降至零，这代表可以暂停通信。而新一代的I²C总线可以和更多的节点（支持10比特长度的地址空间）以更快的速率通信：快速模式（400 kbit/s）、快速+模式（1 Mbit/s）高速模式（3.4 Mbit/s）超高速模式（5 Mbit/s）。

i2c在容易线长导致信号质量不佳，速度越快能用的距离越短(一般约在10公分上下)，上拉电阻用小一点可能有帮助。2c阻抗50,usb阻抗100在做信号转换时阻抗不匹配会造成信号极差

其通信过程如下

二、实战

2.1 工程配置

打开cubeMX进行配置

开启I2C1，设置速率为Fast Mode Plus，即快速+模式，初始化时钟等等

2.2 测试工程

打开生成的工程，添加测试代码

函数具体说明如下

2.3 波形分析

使用逻辑分析仪查看波形如下 

注意到在写完地址0x78后多了一个0，查看datasheet

当对器件进行写入时，最后一位为0

三、驱动OLED

知道HAL库对I2C的发送过程后，阅读ssd1306的datasheet，进行驱动的编写

使用器件需要对器件进行初始化，阅读手册进行配置即可

其间用到一条重要的函数即

void SSD1306_WriteByte(uint8_t dat,uint8_t cmd)；

功能是通过I2C总线对ssd1306进行数据发送

阅读手册，在发送一个命令或数据时，要先发送控制字节，告知接下来发的是数据还是指令。因此函数实现如下

void SSD1306_WriteByte(uint8_t dat,uint8_t cmd)
{
	uint8_t buffer[2];
	buffer[0]=cmd;
	buffer[1]=dat;
	HAL_I2C_Master_Transmit(&hi2c1,0x78,buffer,2,0xffff);
}

HAL_I2C_Master_Transmit()函数一次发两个字节过去，第一个字节告知是数据还是指令，第二个字节为数据或指令。

 如果是数据则先发送0x40，如果是指令则先发送0x00.

使用这个函数对oled进行初始化配置函数的编写

主要指令内容集中在这几章，整个datasheet约60页，开头为目录和介绍，末尾是封装信息。

指令表中有基本指令，滚动指令，地址设置指令，硬件配置指令，时序及驱动指令

用到的为除滚动指令外的四个

 光看指令表会有些陌生，可以结合下面的描述来看

3.1 初始化代码

void OLED_Init()
{
	HAL_Delay(100);
	SSD1306_WriteByte(0xAE,OLED_CMD); //display off
	
	SSD1306_WriteByte(0x20,OLED_CMD); //Set Memory Addressing Mode   
	SSD1306_WriteByte(0x10,OLED_CMD); //00,Horizontal Addressing Mode;01,Vertical Addressing Mode;10,Page Addressing Mode (RESET);11,Invalid
	
	SSD1306_WriteByte(0x00,OLED_CMD); //---set low column address
	SSD1306_WriteByte(0x10,OLED_CMD); //---set high column address
	
	SSD1306_WriteByte(0xB0,OLED_CMD); //Set Page Start Address for Page Addressing Mode,0-7
	SSD1306_WriteByte(0xC8,OLED_CMD); //Set COM Output Scan Direction

	SSD1306_WriteByte(0x40,OLED_CMD); //--set start line address
	
	SSD1306_WriteByte(0x81,OLED_CMD); //--set contrast control register
	SSD1306_WriteByte(0xff,OLED_CMD); //对比度设置
	
	SSD1306_WriteByte(0xA1,OLED_CMD); //--set segment re-map 0 to 127
	SSD1306_WriteByte(0xC8,OLED_CMD); //--set segment re-map 0 to 127
	
	SSD1306_WriteByte(0xA6,OLED_CMD); //--set normal display
	
	SSD1306_WriteByte(0xA8,OLED_CMD); //--set multiplex ratio(1 to 64)
	SSD1306_WriteByte(0x3F,OLED_CMD); //
	
	SSD1306_WriteByte(0xA4,OLED_CMD); //0xa4,Output follows RAM content;0xa5,Output ignores RAM content
	
	SSD1306_WriteByte(0xD3,OLED_CMD); //-set display offset
	SSD1306_WriteByte(0x00,OLED_CMD); //-not offset
	
	SSD1306_WriteByte(0xD5,OLED_CMD); //--set display clock divide ratio/oscillator frequency
	SSD1306_WriteByte(0xF0,OLED_CMD); //--set divide ratio
	
	SSD1306_WriteByte(0xD9,OLED_CMD); //--set pre-charge period
	SSD1306_WriteByte(0x22,OLED_CMD); //
	
	SSD1306_WriteByte(0xDA,OLED_CMD); //--set com pins hardware configuration
	SSD1306_WriteByte(0x12,OLED_CMD);
	
	SSD1306_WriteByte(0xDB,OLED_CMD); //--set vcomh
	SSD1306_WriteByte(0x20,OLED_CMD); //0x20,0.77xVcc
	
	SSD1306_WriteByte(0x8D,OLED_CMD); //--set DC-DC enable
	SSD1306_WriteByte(0x14,OLED_CMD); //
	SSD1306_WriteByte(0xAF,OLED_CMD); //--turn on SSD1306 panel
}

 OLED_CMD使用宏定义，其值为0x00

根据描述，第一步先设置地址模式为页地址模式，注意这个指令是双字节的，意思是发送0x20后要继续发送一个指令联合起来进行设置。根据手册，第二个指令为 0x10

然后设置列地址起始位置，由于屏幕横向有128个像素点，就有128列，手册将地址设置分成高四位地址设置和低四位地址设置，用两个指令来完成，分别是0x00~0x0F控制低四位，0x10~0x1F控制高四位，手册中的例子为低地址指令0x03，高地址为0x10，则最终列起始地址为0x03即SEG3

重要的指令为页起始地址设置指令，就是上面的0x10~0x1f和0x00~0x0f，实际上前者不能为0x1f，因为只有128列，显然f*16=240>128

3.2 清屏函数

void OLED_Clear()
{
     uint8_t i,n;		    
	for(i=0;i<8;i++)  
	{  
		SSD1306_WriteByte (0xb0+i,OLED_CMD);    //设置页地址（0~7）
		SSD1306_WriteByte (0x00,OLED_CMD);      //设置显示位置—列低地址
		SSD1306_WriteByte (0x10,OLED_CMD);      //设置显示位置—列高地址   
		for(n=0;n<128;n++)
			SSD1306_WriteByte(0,OLED_DATA); //write 0x00;
	} //更新显示
}

外层循环8次，对应8个page，每个page由纵向8个像素，横向128列构成。设置页地址起始列为最左边即SEG0，将这128列都填充数据0x00，显示出来就是一片黑色

3.3 设置坐标函数

void OLED_Set_Pos(unsigned char x, unsigned char y) 
{ 	
	SSD1306_WriteByte(0xb0+y,OLED_CMD);						//page y
	SSD1306_WriteByte(((x&0xf0)>>4)|0x10,OLED_CMD);			//high 4 address
	SSD1306_WriteByte((x&0x0f),OLED_CMD); 					//low 4 address
} 

形参y设置page，范围为0到7，对应的指令为0xb0~0xb7。形参x设置起始页列地址，范围为0~127对应SEG0~SEG127。需要对x进行分块，分成高半字节和低半字节

编写主函数代码如下

 OLED在左上角显示字符A，高度为8像素，宽为6像素，图中6行发送数据的函数将字符A的6列一一发送过去，且OLED的列指针会自动加一，因此不必反复设置列指针位置 

 当然，写成下面这样也是可以的

这里会有一个疑问，就是这些数据是怎么得到的，总不会一个个去画吧。实际这是对A进行字体大小为8*6的取模得到的。网上有许多取模软件，一般会将ASCII码全部取出，并存放在一个数组中，需要用到时只需要发送对应行的数据

3.4 显示字符函数

void OLED_ShowChar(uint8_t x,uint8_t y,uint8_t chr,uint8_t Char_Size)
{      	
	unsigned char c=0,i=0;	
		c=chr-' ';//得到偏移后的值			
		if(x>Max_Column-1){x=0;y=y+2;}
		if(Char_Size ==16)
			{
				OLED_Set_Pos(x,y);	
				for(i=0;i<8;i++)
				SSD1306_WriteByte(F8X16[c*16+i],OLED_DATA);
				OLED_Set_Pos(x,y+1);
				for(i=0;i<8;i++)
				SSD1306_WriteByte(F8X16[c*16+i+8],OLED_DATA);
			}
		else 
			{	
				OLED_Set_Pos(x,y);
				for(i=0;i<6;i++)
				SSD1306_WriteByte(F6x8[c][i],OLED_DATA);
			}
}

这个字符显示函数只有高8和高16两种大小的字符显示功能，其中显示高度为16像素的字符时，涉及到两页，需要将y+1。先将上半部分的8列写入再将下半部分8列写入。但是想写高为12，14，20等等的字体需要用另一种方法

3.5 显示字符串函数

void OLED_ShowString(uint8_t x,uint8_t y,uint8_t *chr,uint8_t Char_Size)
{
	unsigned char j=0;
	while (chr[j]!='\0')
	{		OLED_ShowChar(x,y,chr[j],Char_Size);
			x+=8;
		if(x>120){x=0;y+=2;}
			j++;
	}
}

效果如下

如果想显示数字的话，使用sprintf函数进行转换为字符串，然后显示对应的字符串即可。

3.6 显示图片函数

这里以经典的PCtoLCD2002为例

取模设置如下

 参考手册页地址模式

选择低位在前，且为列行式，使用一维数组储存，右边格式前缀后缀稍作修改。

由于图片包含取模信息和图片的长度宽度，使用结构体进行定义 

typedef struct
{
	uint8_t xSize;
	uint8_t ySize;
	const unsigned char *p;
}BMP;

将这个声明放到oled.h中，因为oled.c有显示图片函数需要用到

 将取好的图片模和字模放到一个.h文件中

const unsigned char bmp_data[]=
{
0x00,0x00,0x00,0x80,0x80,0x80,0x80,0x00,0x80,0x80,0x60,0x40,0x80,0x80,0xC0,0xE0,
0xE0,0x40,0x20,0x10,0x50,0xB0,0xE0,0xC0,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,
0x1C,0x1F,0x09,0x18,0x18,0x10,0x10,0x01,0x1F,0x1F,0x1F,0x1F,0x09,0x01,0x11,0x15,
0x10,0x11,0x11,0x1F,0x1D,0x1C,0x1F,0x17,0x12,0x18,0x10,0x10,0x11,0x18,0x1F,0x1F
};

BMP bmp=
{
	32,	//宽像素
	13,	//高像素
	bmp_data
};

并将bmp用extern修饰

extern BMP bmp;

显示函数如下

void OLED_ShowPic(uint8_t x,uint8_t y,BMP bmp)
{
	uint8_t xsize=bmp.xSize;
	uint8_t ysize=bmp.ySize;
	OLED_Set_Pos(x,y);
	//如果像素高度不是8的倍数，则整除后加1补上
	if(ysize%8!=0)
		ysize=ysize+8;
	uint8_t i,j;
	for(i=0;i<ysize/8;i++)
	{
		OLED_Set_Pos(x,y+i);
		for(j=0;j<xsize;j++)
		SSD1306_WriteByte(*(bmp.p+i*xsize+j),OLED_DATA);
	}
}

主函数编写

 显示效果如下
