一、簡單介紹

1.1? ?OLED

有機發(fā)光二極管（英語：Organic Light-Emitting Diode，縮寫：OLED）又稱有機電激發(fā)光顯示（英語：Organic Electroluminescence Display，縮寫：OELD）、有機發(fā)光半導(dǎo)體，OLED技術(shù)最早于1950年代和1960年代由法國人和美國人研制，其后由美國柯達及英國劍橋大學(xué)加以演進，日本SONY及韓國三星和LG等公司于21世紀(jì)開始量產(chǎn)，現(xiàn)在的市場都趨近于OLED但是在壽命上比LCD短。[來源請求]

OLED（有機發(fā)光二極管）與TFT-LCD（薄膜晶體管液晶顯示器）為不同類型的產(chǎn)品，OLED具有自發(fā)光性、廣視角、高對比、低耗電、高反應(yīng)速率、全彩化及制程簡單等優(yōu)點，但相對的在大面板價格、技術(shù)選擇性 、壽命、分辨率、色彩還原方面便無法與TFT-LCD匹敵，有機發(fā)光二極管顯示器可分單色、多彩及全彩等種類，而其中以全彩制作技術(shù)最為困難。

OLED顯示器依驅(qū)動方式的不同又可分為被動式（Passive Matrix，PMOLED）與主動式（Active Matrix，AMOLED）。

筆者使用的oled如上圖，四針腳I2C協(xié)議，主控為SSD1306。

規(guī)格為0.96寸，分辨率為128*64

1.2? ?I2C協(xié)議

I2C（Inter-Integrated Circuit）字面上的意思是集成電路之間，它其實是I2C Bus簡稱，所以中文應(yīng)該叫集成電路總線，它是一種串行通信總線，使用多主從架構(gòu)，由飛利浦公司在1980年代為了讓主板、嵌入式系統(tǒng)或手機用以連接低速周邊設(shè)備而發(fā)展。I2C的正確讀法為“I平方C”（"I-squared-C"），而“I二C”（"I-two-C"）則是另一種錯誤但被廣泛使用的讀法。自2006年10月1日起，使用I2C協(xié)議已經(jīng)不需要支付專利費，但制造商仍然需要付費以獲取I2C從屬設(shè)備地址[1]。

I2C的參考設(shè)計使用一個7比特長度的地址空間但保留了16個地址，所以在一組總線最多可和112個節(jié)點通信[a]。常見的I2C總線依傳輸速率的不同而有不同的模式：標(biāo)準(zhǔn)模式（100 kbit/s）、低速模式（10 kbit/s），但時鐘頻率可被允許下降至零，這代表可以暫停通信。而新一代的I2C總線可以和更多的節(jié)點（支持10比特長度的地址空間）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在容易線長導(dǎo)致信號質(zhì)量不佳，速度越快能用的距離越短(一般約在10公分上下)，上拉電阻用小一點可能有幫助。2c阻抗50,usb阻抗100在做信號轉(zhuǎn)換時阻抗不匹配會造成信號極差

其通信過程如下

二、實戰(zhàn)

2.1 工程配置

打開cubeMX進行配置

開啟I2C1，設(shè)置速率為Fast Mode Plus，即快速+模式，初始化時鐘等等

2.2 測試工程

打開生成的工程，添加測試代碼

函數(shù)具體說明如下

2.3 波形分析

使用邏輯分析儀查看波形如下?

注意到在寫完地址0x78后多了一個0，查看datasheet

當(dāng)對器件進行寫入時，最后一位為0

三、驅(qū)動OLED

知道HAL庫對I2C的發(fā)送過程后，閱讀ssd1306的datasheet，進行驅(qū)動的編寫

使用器件需要對器件進行初始化，閱讀手冊進行配置即可

其間用到一條重要的函數(shù)即

void SSD1306_WriteByte(uint8_t dat,uint8_t cmd)；

功能是通過I2C總線對ssd1306進行數(shù)據(jù)發(fā)送

閱讀手冊，在發(fā)送一個命令或數(shù)據(jù)時，要先發(fā)送控制字節(jié)，告知接下來發(fā)的是數(shù)據(jù)還是指令。因此函數(shù)實現(xiàn)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()函數(shù)一次發(fā)兩個字節(jié)過去，第一個字節(jié)告知是數(shù)據(jù)還是指令，第二個字節(jié)為數(shù)據(jù)或指令。

?如果是數(shù)據(jù)則先發(fā)送0x40，如果是指令則先發(fā)送0x00.

使用這個函數(shù)對oled進行初始化配置函數(shù)的編寫

主要指令內(nèi)容集中在這幾章，整個datasheet約60頁，開頭為目錄和介紹，末尾是封裝信息。

指令表中有基本指令，滾動指令，地址設(shè)置指令，硬件配置指令，時序及驅(qū)動指令

用到的為除滾動指令外的四個

?光看指令表會有些陌生，可以結(jié)合下面的描述來看

3.1?初始化代碼

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); //對比度設(shè)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使用宏定義，其值為0x00

根據(jù)描述，第一步先設(shè)置地址模式為頁地址模式，注意這個指令是雙字節(jié)的，意思是發(fā)送0x20后要繼續(xù)發(fā)送一個指令聯(lián)合起來進行設(shè)置。根據(jù)手冊，第二個指令為?0x10

然后設(shè)置列地址起始位置，由于屏幕橫向有128個像素點，就有128列，手冊將地址設(shè)置分成高四位地址設(shè)置和低四位地址設(shè)置，用兩個指令來完成，分別是0x00~0x0F控制低四位，0x10~0x1F控制高四位，手冊中的例子為低地址指令0x03，高地址為0x10，則最終列起始地址為0x03即SEG3

重要的指令為頁起始地址設(shè)置指令，就是上面的0x10~0x1f和0x00~0x0f，實際上前者不能為0x1f，因為只有128列，顯然f*16=240>128

3.2 清屏函數(shù)

void OLED_Clear()
{
     uint8_t i,n;		    
	for(i=0;i<8;i++)  
	{  
		SSD1306_WriteByte (0xb0+i,OLED_CMD);    //設(shè)置頁地址（0~7）
		SSD1306_WriteByte (0x00,OLED_CMD);      //設(shè)置顯示位置—列低地址
		SSD1306_WriteByte (0x10,OLED_CMD);      //設(shè)置顯示位置—列高地址   
		for(n=0;n<128;n++)
			SSD1306_WriteByte(0,OLED_DATA); //write 0x00;
	} //更新顯示
}

外層循環(huán)8次，對應(yīng)8個page，每個page由縱向8個像素，橫向128列構(gòu)成。設(shè)置頁地址起始列為最左邊即SEG0，將這128列都填充數(shù)據(jù)0x00，顯示出來就是一片黑色

3.3 設(shè)置坐標(biāo)函數(shù)

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
} 

形參y設(shè)置page，范圍為0到7，對應(yīng)的指令為0xb0~0xb7。形參x設(shè)置起始頁列地址，范圍為0~127對應(yīng)SEG0~SEG127。需要對x進行分塊，分成高半字節(jié)和低半字節(jié)

編寫主函數(shù)代碼如下

?OLED在左上角顯示字符A，高度為8像素，寬為6像素，圖中6行發(fā)送數(shù)據(jù)的函數(shù)將字符A的6列一一發(fā)送過去，且OLED的列指針會自動加一，因此不必反復(fù)設(shè)置列指針位置?

?當(dāng)然，寫成下面這樣也是可以的

這里會有一個疑問，就是這些數(shù)據(jù)是怎么得到的，總不會一個個去畫吧。實際這是對A進行字體大小為8*6的取模得到的。網(wǎng)上有許多取模軟件，一般會將ASCII碼全部取出，并存放在一個數(shù)組中，需要用到時只需要發(fā)送對應(yīng)行的數(shù)據(jù)

3.4 顯示字符函數(shù)

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);
			}
}

這個字符顯示函數(shù)只有高8和高16兩種大小的字符顯示功能，其中顯示高度為16像素的字符時，涉及到兩頁，需要將y+1。先將上半部分的8列寫入再將下半部分8列寫入。但是想寫高為12，14，20等等的字體需要用另一種方法

3.5 顯示字符串函數(shù)

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

如果想顯示數(shù)字的話，使用sprintf函數(shù)進行轉(zhuǎn)換為字符串，然后顯示對應(yīng)的字符串即可。

3.6 顯示圖片函數(shù)

這里以經(jīng)典的PCtoLCD2002為例

取模設(shè)置如下

?參考手冊頁地址模式

選擇低位在前，且為列行式，使用一維數(shù)組儲存，右邊格式前綴后綴稍作修改。

由于圖片包含取模信息和圖片的長度寬度，使用結(jié)構(gòu)體進行定義?

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

將這個聲明放到oled.h中，因為oled.c有顯示圖片函數(shù)需要用到

?將取好的圖片模和字模放到一個.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,	//寬像素
	13,	//高像素
	bmp_data
};

并將bmp用extern修飾

extern BMP bmp;

顯示函數(shù)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的倍數(shù)，則整除后加1補上
	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);
	}
}

主函數(shù)編寫

?顯示效果如下
