我們是采用鄭州中景圓的0.96寸的oled屏，單片機(jī)為stm32F103，通訊方式是三線SPI，下面是屏的簡(jiǎn)單介紹

主要由裸屏和底板PCB組成，裸屏由SSD1306驅(qū)動(dòng)，這也是一種較為廣泛使用的led驅(qū)動(dòng)芯片。

得到一塊新的屏幕，最重要的就是看能否點(diǎn)亮，點(diǎn)亮了才能使用做各種顯示應(yīng)用。就是需要SPI驅(qū)動(dòng)程序移植一下，問(wèn)題不大。

1.配置SPI，初始化，采用硬件SPI方式驅(qū)動(dòng)

GPIO_InitTypeDef  GPIO_InitStructure;
	SPI_InitTypeDef SPI_InitStructure;
	
//	RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOB, ENABLE);
	RCC_APB2PeriphClockCmd(RCC_APB2Periph_SPI1, ENABLE);//使能SPI1時(shí)鐘
	
	
	/* 配置OLED_DC(PA6),OLED_RST(PA4) */
 	RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA,ENABLE);
	GPIO_InitStructure.GPIO_Pin = GPIO_Pin_6|GPIO_Pin_4;	
 	GPIO_InitStructure.GPIO_Mode = GPIO_Mode_Out_PP; 		 
	GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
 	GPIO_Init(GPIOA, &GPIO_InitStructure);
	
	/* 配置SPI1的 SCK(PA5),MOSI(PA7)引腳 */ 
	GPIO_InitStructure.GPIO_Pin = GPIO_Pin_5| GPIO_Pin_7; 
	GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP;
	GPIO_Init(GPIOA, &GPIO_InitStructure);

	SPI_InitStructure.SPI_Direction = SPI_Direction_2Lines_FullDuplex;	/* 設(shè)置SPI單向或者雙向的數(shù)據(jù)模式 */
	SPI_InitStructure.SPI_Mode = SPI_Mode_Master;		/* 設(shè)置SPI工作模式:設(shè)置為主SPI */
	SPI_InitStructure.SPI_DataSize = SPI_DataSize_8b;	/* 設(shè)置SPI的數(shù)據(jù)大小:SPI發(fā)送接收8位幀結(jié)構(gòu) */
	SPI_InitStructure.SPI_CPOL = SPI_CPOL_High;			/* 選擇了串行時(shí)鐘的穩(wěn)態(tài):時(shí)鐘懸空低 */
	SPI_InitStructure.SPI_CPHA = SPI_CPHA_2Edge;		/* 數(shù)據(jù)捕獲于第二個(gè)時(shí)鐘沿 */
	SPI_InitStructure.SPI_NSS = SPI_NSS_Soft;			/* NSS信號(hào)由硬件（NSS管腳）還是軟件（使用SSI位）管理:內(nèi)部NSS信號(hào)有SSI位控制 */
	SPI_InitStructure.SPI_BaudRatePrescaler = SPI_BaudRatePrescaler_4;	/* 定義波特率預(yù)分頻的值:波特率預(yù)分頻值為4 */
	SPI_InitStructure.SPI_FirstBit = SPI_FirstBit_MSB;	/* 指定數(shù)據(jù)傳輸從MSB位還是LSB位開(kāi)始:數(shù)據(jù)傳輸從MSB位開(kāi)始 */
	SPI_InitStructure.SPI_CRCPolynomial = 0;			/* CRC值計(jì)算的多項(xiàng)式*/
	SPI_Init(SPI1, &SPI_InitStructure); 				/* 根據(jù)SPI_InitStruct中指定的參數(shù)初始化外設(shè)SPIx寄存器 */
 
	SPI_Cmd(SPI1, ENABLE); /* 使能SPI外設(shè) */
	
	//OLED_CS=1;
//	OLED_RS=1;
    OLED_RST=1; 
	delay_ms(100);
	
	OLED_RST=0;
	delay_ms(100);
	OLED_RST=1; 

采用硬件SPI的方式，不用IO口來(lái)模擬SPI的時(shí)序了，但是OLED屏上電后需要相關(guān)的設(shè)置，都是廠家提供的初始化代碼

2.如何點(diǎn)亮OLED并顯示呢

需要通過(guò)取模軟件PCtoLCD2002取出你想要的漢字，比如字體大小等都可以設(shè)置，我們顯示電子星球

并建立多維數(shù)組，存儲(chǔ)字模，

const unsigned char Hzk[][16] = {
 {0x00,0x00,0xF8,0xF8,0x88,0x88,0x88,0xFF,0xFF,0x88,0x88,0x88,0xF8,0xF8,0x00,0x00},
{0x00,0x00,0x1F,0x1F,0x08,0x08,0x08,0x7F,0xFF,0x88,0x88,0x88,0x9F,0x9F,0xF0,0xF0},/*"電",0*/

{0x80,0x82,0x82,0x82,0x82,0x82,0x82,0xE2,0xE2,0xB2,0x9A,0x8E,0x86,0x82,0x80,0x80},
{0x00,0x00,0x00,0x00,0x00,0x40,0xC0,0xFF,0x7F,0x00,0x00,0x00,0x00,0x00,0x00,0x00},/*"子",1*/

{0x00,0x00,0x00,0xBE,0xBE,0x2A,0x2A,0xEA,0xEA,0x2A,0x2A,0x3E,0x3E,0x00,0x00,0x00},
{0x00,0x44,0x46,0x4B,0x49,0x49,0x49,0x7F,0x7F,0x49,0x49,0x49,0x49,0x41,0x40,0x00},/*"星",2*/

{0x04,0x84,0x84,0xFC,0xFC,0x84,0x94,0x50,0xD0,0x90,0xFF,0xFF,0x91,0x17,0x96,0x90},
{0x20,0x60,0x60,0x3F,0x1F,0x10,0x10,0x18,0x4D,0xC7,0xFF,0x7F,0x07,0x0F,0x19,0x10},/*"球",3*/

主函數(shù)調(diào)用SPI寫(xiě)函數(shù)就可以了

同樣的方法顯示welcome，看最后顯示效果
