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，七针脚SPI协议，主控为SSD1306。

规格为0.96寸，分辨率为128*64

1.2 SPI协议

串行外设接口（Serial Peripheral Interface Bus，SPI），是一种用于芯片通信的同步串行通信接口规范，主要应用于单片机系统中。类似I²C。 这种接口首先由摩托罗拉公司于20世纪80年代中期开发，后发展成了行业规范。它的典型应用有闪存[1][2]、EEPROM、SD卡与液晶显示器。

SPI设备之间使用全双工模式通信，是一个主机和一个或多个从机的主从模式。主机负责初始化帧，这个数据传输帧可以用于读与写两种操作，片选线路可以从多个从机选择一个来响应主机的请求。

有时SPI接口被称作四线式接口，这是为了与其他不同线制的数据传输接口加以区分。SPI准确来讲应为“同步串行接口”，但是它又与同步串行接口协议（SSI）是完全不同的两种协议。虽然SSI也是一个四线式同步通信协议，但是它使用差分信号，而且仅提供一个单工通信信道。于此相对地，SPI是一个单主机多从机的通信接口。

SPI是一种事实标准，也就是说这种规范没有对应的技术标准。因此各个厂家生产的SPI器件配置不一样，不一定有互操作性。

接口

SPI总线规定了4个保留逻辑信号接口：

• SCLK（Serial Clock）：串列时脉，由主机发出
• MOSI（Master Output, Slave Input）：主机输出从机输入信号（数据由主机发出）
• MISO（Master Input, Slave Output）：主机输入从机输出信号（数据由从机发出）
• SS（Slave Select）：片选信号，由主机发出，一般是低电位有效

尽管上面的引脚名称是最常用的，但在过去，有时会使用其他引脚命名方式，因此旧的集成电路产品的SPI端口引脚名称可能有所不同。

优点

• SPI协议默认是全双工通信。
• 与漏极开路输出相反，SPI的推挽输出可提供良好的信号完整性和高速度
• 比I²C或SMBus更高的传输带宽 。 不限于任何最大时钟频率，可实现高速运行
• 完整的传输位协议灵活性
  • 不限于8位字
  • 任意选择消息大小，内容和目的地
• 简单的线路连接
  • 由于电路较少（包括上拉电阻），因此通常比I²C或SMBus的功耗要低，
  • 没有仲裁或相关的失败模式
  • 从站与主机使用同一主频来源，不需要各自配置精密振荡器
  • 从站不需要唯一的地址 - 不像I²C或GPIB或SCSI
  • 不需要收发器
• IC封装只使用四个引脚，而电路板布局或连接器则少于并行接口
• 每个器件至多有一个独特的总线信号（芯片选择）;其他信号均可以共享
• 信号是单向的，允许简单的电气隔离
• 软件撰写简易

缺点

• 即使是三线式SPI，也需要比I²C更多的IC线路
• 没有带内寻址; 共享总线上需要带外片选信号
• 从机不支持流控制 （但主机可以延迟下一个时钟边沿以降低传输速率）
• 不支持动态添加节点（热插拔）。
  • 没有从机检测机制，主机无法检测是否与从机断开。
• 通常只支持一个主设备（取决于设备的硬件实现）
• 没有错误检测机制，不像I²C在每个字节后有回复信号
• 无法进行数据检验，不定义额外的协议时（如CRC）无法保证数据正确性。
• 与RS-232 ， RS-485或CAN总线相比，它只能处理短距离内的数据传输。（距离可以通过使用收发器如RS-422进行扩展）
• 有许多现有的变体，使得很难找到支持这些变体的主机适配器等开发工具。
  • 一些变体，如双路SPI ， 四路SPI和三线SPI是半双工的。
• 必须通过带外信号来实现中断，或者通过使用类似于USB 1.1和2.0的定期轮询来模拟中断

数据传输

为了开始通信，总线上的主设备需要使用从设备支持的频率来配置时钟，这个频率最高为几兆赫兹左右。然后主设备将某个从设备的SS线置为低电平，来选中这个从设备。如果等待时间是必要的话（例如进行模数转换），主设备必须在这段时间结束后，才可以发出时钟周期讯号。

在每个SPI时钟周期内，都会发生全双工数据传输。主设备在MOSI线上发送一个位，从设备读取它，同时从机在MISO线上发送一位数据，主机读取它。即使只有单向数据传输的目的，主从机之间的通信工作方式仍然是双工的。

​

两个连接成虚拟环形缓冲器的移位寄存器

传输通常会使用给定字长的两个移位寄存器，一个在主设备中，一个在从设备中，这两个寄存器连接成一个虚拟的环形缓冲器。数据通常先从最高位移出。在时钟讯号边沿，主机和从机均移出一位，然后在传输线上输出给对方。在下一个时钟沿，每个接收器都从传输线接受对方发出的数据位，并且从移位寄存器的最低位推入。每完成这样一个移出——推入的周期后，主机和从机就交换寄存器中的一位数据。当所有数据位都经过了这样的移出——推入过程后，主机和从机就完成了寄存器上的数据交换。如果需要交换的数据比寄存器的位数还要长的话，则需要重新加载移位寄存器并重复该过程。传输可能会持续任意数量的时钟周期。完成后，主设备会停止发送时钟讯号，并通常会取消选择从设备。

传输寄存器通常包含8位。但是其他字长也很常见，例如触摸屏控制器或音频编解码器通常采用16位字长（如德州仪器的TSC2101），许多数模转换或者模数转换的设备则会采用12位字长。

所有在总线上的没有被片选线激活的从设备必须忽略输入时钟和MOSI讯号，并且不得从MISO发送数据。

二、实战

2.1 工程配置

打开cubeMX进行配置

​

​

开启SPI1，我这里GPIO是根据板子上的接口来设定的，大家灵活配置即可。波特率我设置了3M的速率，实际上更高到12M也是没问题的，不过那样的话逻辑分析仪采集信号就会有损失，为了方便演示，笔者就16分频了。

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

​

但是这仅仅有发送数据，没有设置CS，SC，RES引脚的电平

三、驱动OLED

知道HAL库对SPI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SPI总线对ssd1306进行数据发送

OLED通信过程如下

​

​

当片选信号CS电平为低时器件被主机选中，由DC引脚控制发生的是命令还是数据

如果是数据则高电平，如果是指令则低电平.

void SSD1306_WriteByte(uint8_t dat,uint8_t cmd)
{
	uint8_t buffer[1];
	buffer[0]=dat;
	if(cmd==OLED_CMD)
	{
		HAL_GPIO_WritePin(DC_GPIO_Port,DC_Pin,GPIO_PIN_RESET);
		HAL_SPI_Transmit(&hspi1,buffer,1,0xffff);
	}
	else if(cmd==OLED_DATA)
	{
		HAL_GPIO_WritePin(DC_GPIO_Port,DC_Pin,GPIO_PIN_SET);
		HAL_SPI_Transmit(&hspi1,buffer,1,0xffff);
	}
}

HAL_SPI_Transmit()函数一次发一个字节过去，参数cmd告知是数据还是指令，选择DC引脚的电平

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_GPIO_WritePin(RES_GPIO_Port,RES_Pin,GPIO_PIN_RESET);
	HAL_Delay(100);
	HAL_GPIO_WritePin(RES_GPIO_Port,RES_Pin,GPIO_PIN_SET);
	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(0xB0,OLED_CMD); //Set Page Start Address for Page Addressing Mode,0-7
	
	SSD1306_WriteByte(0x00,OLED_CMD); //---set low column address
	SSD1306_WriteByte(0x10,OLED_CMD); //---set high column address
	
	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); //¶Ô±È¶ÈÉèÖÃ
	
	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);    //ÉèÖÃÒ³µØÖ·£¨0~7£©
		SSD1306_WriteByte (0x00,OLED_CMD);      //ÉèÖÃÏÔʾλÖáªÁе͵ØÖ·
		SSD1306_WriteByte (0x10,OLED_CMD);      //ÉèÖÃÏÔʾλÖáªÁиߵØÖ·   
		for(n=0;n<128;n++)
			SSD1306_WriteByte(0,OLED_DATA); //write 0x00;
	} //¸üÐÂÏÔʾ
}

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

以这个苹果图片为例

 将取好的图片模和字模放到一个.h文件中

const unsigned char bmp_data[]=
{
0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,

};

BMP bmp=
{
	64,	//¿íÏñËØ
	64,	//¸ßÏñËØ
	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

OLED_Init();
OLED_Clear();
OLED_ShowPic(32,0,bmp);

 显示效果如下
