OLED驅動原理—IIC通信：

這里是基礎原理，可以大致瀏覽即可，有個基本印象：

下圖為 0.96寸單色OLED，他們有四個針腳：VCC GND SCK SDA?

?前倆個就是供電的，后倆個是IIC通信接口，與單片機通信。

SSD1306 單色 0.96 OLED 顯示屏特性

OLED顯示屏可以從最大160度的各個角度觀看。
該顯示器支持 3v 和 5v 電源，這使得它可以與 3.3V 和 5V 邏輯一起工作。
SSD1306驅動程序及其庫使OLED可以通過簡單的命令顯示字符和位圖。
不同顏色的 OLED 也可供選擇，甚至不同尺寸也可供選擇。
與 LCD 相比，OLED 顯示屏尺寸更小，顯示效果更好

0.96 寸OLED顯示屏所用的驅動IC為SSD1306；

其具有內部升壓功能；所以在設計的時候不需要再專一設計升壓電路；

當然了本屏也可以選用外部升壓。

SSD1306的每頁包含了128個字節，總共8頁，這樣剛好是 128*64 的點陣大小。

由上圖可知，0.96寸OLED有八頁，128列，每一頁又有8小行：

對于一個0.96寸OLED，有8頁（也可以稱為8個水平掃描線）和128列。通過8頁和128列，可以操作所有64x128個像素點。

第一步是控制頁數：

OLED屏幕的每一頁都是由一組水平掃描線構成的，每次只能顯示一頁。通過控制頁數的切換，我們可以在屏幕上顯示不同的內容。總共有8頁，可以通過指令來切換到目標頁。

第二步是控制列數：

在每一頁上，OLED屏幕有128列。列數確定了水平方向的像素點位置。我們可以通過指令來選擇在特定頁上的目標列。

這樣，我們可以通過控制頁數和列數的組合來操作到所有64x128個像素點。可以根據需要在特定的頁和列上顯示圖形、文字或其他內容。

程序理解與設計：

1.操作時序—寫命令、寫數據：

由上圖可知，在通過IIC嘗試控制OLED時，有倆個主要的操作：1.寫數據0x40 ? 2.寫命令0x00

?因此寫指令與寫數據的操作過程完全一致，只是寫入指令與數據的寄存器不同，一個是0x00,一個是0x40，選擇好了寫入的寄存器是指令還是數據后，就能傳遞我們具體的指令或者數據了：

/**********************************************
// IIC Write Command
**********************************************/
void Write_IIC_Command(unsigned char IIC_Command)
{IIC_Start();Write_IIC_Byte(0x78);            //Slave address,SA0=0IIC_Wait_Ack();	Write_IIC_Byte(0x00);			//write commandIIC_Wait_Ack();	Write_IIC_Byte(IIC_Command); IIC_Wait_Ack();	IIC_Stop();
}
/**********************************************
// IIC Write Data
**********************************************/
void Write_IIC_Data(unsigned char IIC_Data)
{IIC_Start();Write_IIC_Byte(0x78);			//D/C#=0; R/W#=0IIC_Wait_Ack();	Write_IIC_Byte(0x40);			//write dataIIC_Wait_Ack();	Write_IIC_Byte(IIC_Data);IIC_Wait_Ack();	IIC_Stop();
}

二、清屏命令：

接下來講解一下清屏命令，從這個命令我們可以初步明白一下：寫命令與寫數據具體代表什么，以及8頁，128列，究竟是怎么操作的：

首先是整了一個寫入函數，這個函數沒有別的意思，就是整合了Write_IIC_Command（）與Write_IIC_Data(），起到了有命令寫命令，有數據寫數據的效果，主要是方便后續程序編寫，不管寫數據還是命令，直接調用它就行了。

它有倆個參數：第一個參數dat是數據，第二個參數cmd就是選擇這個dat數據是寫入命令寄存器的還是寫入數據寄存器的。

期間還寫了倆個宏定義，用來提醒自己，這里的步驟是寫命令寄存器的還是寫數據寄存器的：

#define OLED_CMD  0	//寫命令
#define OLED_DATA 1	//寫數據void OLED_WR_Byte(unsigned dat,unsigned cmd)
{if(cmd){ Write_IIC_Data(dat);}else { Write_IIC_Command(dat);}
}

//清屏函數,清完屏,整個屏幕是黑色的!和沒點亮一樣!!!	  
void OLED_Clear(void)  
{  u8 i,n;		    for(i=0;i<8;i++)  {  OLED_WR_Byte (0xb0+i,OLED_CMD);    //設置頁地址（0~7）OLED_WR_Byte (0x00,OLED_CMD);      //設置顯示位置—列低地址OLED_WR_Byte (0x10,OLED_CMD);      //設置顯示位置—列高地址   for(n=0;n<128;n++)OLED_WR_Byte(0,OLED_DATA); } //更新顯示
}

我們可以看到，整個函數一進入就是進行一個8次的循環，每次循環進入：

首先就會先選擇哪一頁需要清空，而OLED共有八頁，因此需要循環八次來選擇0~7這八個頁號~

其次選擇哪一列需要清空，因為這是個屏幕，我們使用平面直角坐標系里確定一個點來理解，如果OLED是橫向顯示的，前面的頁就好比確定了Y坐標，這里的列就是確定了X坐標，這樣，先確定了Y，再內套一個循環128次，依次選擇一列上的X進行清空。

綜上：這個函數總共是8*128個循環操作，才使得OLED全部清空~~~

三、初始化SSD1306顯示：

這部分初始化分為單片機IIC引腳的初始化、以及對SSD1306寫入一些必要命令的初始化

在單片機IIC引腳的初始化方面不多說，而對SSD1306寫入一些必要命令方面，我們可以通過我的注釋看出，有對比度、反顯等可以設置，具體寫入什么進行設置可以百度，我這配的都是正常的通用設置：這種寫命令，一般都是先寫寄存器，在寫數據設置：

//初始化SSD1306					    
void OLED_Init(void)
{ 	GPIO_InitTypeDef  GPIO_InitStructure;                  //定義初始化結構體RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOB, ENABLE);	 //使能APB2端口時鐘GPIO_InitStructure.GPIO_Pin = GPIO_Pin_6|GPIO_Pin_7;	 //初始化B6,B7GPIO_InitStructure.GPIO_Mode = GPIO_Mode_Out_PP; 		   //推挽輸出GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;      //速度50MHzGPIO_Init(GPIOB, &GPIO_InitStructure);	               //初始化GPIOBGPIO_SetBits(GPIOB,GPIO_Pin_6|GPIO_Pin_7);							delay_ms(100);                               OLED_WR_Byte(0xAE,OLED_CMD);//--display off                    關閉顯示屏OLED_WR_Byte(0x00,OLED_CMD);//---set low column address        設置低列地址 OLED_WR_Byte(0x10,OLED_CMD);//---set high column address       設置高列地址OLED_WR_Byte(0x40,OLED_CMD);//--set start line address         設置起始行地址OLED_WR_Byte(0xB0,OLED_CMD);//--set page address               設置頁地址OLED_WR_Byte(0x81,OLED_CMD); // contract control               設置對比度控制OLED_WR_Byte(0xFF,OLED_CMD);//--128                            對比度值設置為128OLED_WR_Byte(0xA1,OLED_CMD);//set segment remap                設置段重映射OLED_WR_Byte(0xA6,OLED_CMD);//--normal / reverse               設置正常顯示/反向顯示OLED_WR_Byte(0xA8,OLED_CMD);//--set multiplex ratio(1 to 64)   設置多路復用比率（1到64）OLED_WR_Byte(0x3F,OLED_CMD);//--1/32 duty                      設置Duty值為1/32OLED_WR_Byte(0xC8,OLED_CMD);//Com scan direction               設置COM掃描方向OLED_WR_Byte(0xD3,OLED_CMD);//-set display offset              設置顯示偏移OLED_WR_Byte(0x00,OLED_CMD);//                                 設置顯示起始行OLED_WR_Byte(0xD5,OLED_CMD);//set osc division                 設置振蕩器分頻OLED_WR_Byte(0x80,OLED_CMD);//                                 設置振蕩器分頻值為80OLED_WR_Byte(0xD8,OLED_CMD);//set area color mode off          設置區域顏色模式關閉OLED_WR_Byte(0x05,OLED_CMD);//                                 設置區域顏色模式值為05OLED_WR_Byte(0xD9,OLED_CMD);//Set Pre-Charge Period            設置預充電周期OLED_WR_Byte(0xF1,OLED_CMD);//                                 設置預充電周期值為F1OLED_WR_Byte(0xDA,OLED_CMD);//set com pin configuartion        設置COM引腳配置OLED_WR_Byte(0x12,OLED_CMD);//                                 設置COM引腳配置值為12OLED_WR_Byte(0xDB,OLED_CMD);//set Vcomh                        設置VcomhOLED_WR_Byte(0x30,OLED_CMD);//                                 設置Vcomh值為30OLED_WR_Byte(0x8D,OLED_CMD);//set charge pump enable           設置充電泵使能OLED_WR_Byte(0x14,OLED_CMD);//                                 設置充電泵使能值為14OLED_WR_Byte(0xAF,OLED_CMD);//--turn on oled panel             打開顯示屏
}

四、開啟與關閉指令：

這是OLED開啟與關閉的函數，主要原理也是向它的寄存器寫數據命令，可以快捷開啟關閉OLED，一般程序初始化時會關閉OLED，防止亂顯示，初始化完成后打開即可：

有時開機刷新比較慢，像素可能會一行一行刷出來，這時可以先調用 OLED_Display_Off（），在緊接著調用刷新顯示的函數，然后在調用OLED_Display_On（），像素就不會一行一行刷出來了~~原理就是等他刷新顯示的函數循環加載完成了，再整個打開OLED：

//開啟OLED顯示    
void OLED_Display_On(void)
{OLED_WR_Byte(0X8D,OLED_CMD);  //SET DCDC命令OLED_WR_Byte(0X14,OLED_CMD);  //DCDC ONOLED_WR_Byte(0XAF,OLED_CMD);  //DISPLAY ON
}
//關閉OLED顯示     
void OLED_Display_Off(void)
{OLED_WR_Byte(0X8D,OLED_CMD);  //SET DCDC命令OLED_WR_Byte(0X10,OLED_CMD);  //DCDC OFFOLED_WR_Byte(0XAE,OLED_CMD);  //DISPLAY OFF
}

五、OLED坐標設置：

這是設置OLED顯示繪制起點的函數，每種文字，圖像都有占用的范圍，比如宋體漢字，每個字一般占用16*16像素,而字母可以占用更少的像素區域~~：

//坐標設置
void OLED_Set_Pos(unsigned char x, unsigned char y) 
{ OLED_WR_Byte(0xb0+y,OLED_CMD);OLED_WR_Byte(((x&0xf0)>>4)|0x10,OLED_CMD);OLED_WR_Byte((x&0x0f),OLED_CMD); 
}

?如圖可以更直觀理解一個中文字是怎么點亮的，小框代表一個中文字需要占用的像素區，大框就是OLED全部顯示區，Y坐標代表頁，X坐標代表列。

六、常用ASCLL碼字符字庫：

?這是常用ASCLL碼字符字庫，分倆種大小：12*6以及16*8的字母：這個直接復制使用即可：

//常用ASCII表
//偏移量32
//ASCII字符集
//偏移量32
//大小:12*6

七、字符顯示函數：

?這是在指定位置顯示一個字符的函數，X,Y是它的起始區域，chr就是該字符的ASCLL碼，Size是選擇它的顯示占用像素點，16*8還是12*6（本質上是引用六中的常用字庫）；

//在指定位置顯示一個字符,包括部分字符
//x:0~127
//y:0~63
//mode:0,反白顯示;1,正常顯示				 
//size:選擇字體 16/12 
void OLED_ShowChar(u8 x,u8 y,u8 chr,u8 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++)OLED_WR_Byte(F8X16[c*16+i],OLED_DATA);OLED_Set_Pos(x,y+1);for(i=0;i<8;i++)OLED_WR_Byte(F8X16[c*16+i+8],OLED_DATA);}else {	OLED_Set_Pos(x,y);for(i=0;i<6;i++)OLED_WR_Byte(F6x8[c][i],OLED_DATA);}
}

程序設計：

在坐標（0,0）處打印一個大寫的A（16*8像素），

在坐標（12,0）處打印一個小寫的b（12*6像素），

并全屏閃爍（每0.5秒）。

主函數代碼：

之前其余函數代碼都一個個講了，因此這里只貼出主函數代碼：

#include "main.h"int main(void)
{	init_ALL();     //初始化所有函數while(1){OLED_ShowChar(0,0,'A',16);OLED_ShowChar(12,0,'b',12);		OLED_Display_On();delay_ms(500);OLED_Display_Off();delay_ms(500);}
}//初始化所有函數：
void init_ALL(void)
{SysTick_Init(72);         //初始化滴答計時器
//	Timer2_Init();						//初始化定時器2i2c_GPIO_Config();	      //IIC初始化	OLED_Init();              //初始化OLED屏幕OLED_Clear();             //清空屏幕數據
}
