可以选择I2C1，也可以选择I2C2，或者同时选择，同时运行

配置时钟信号

为节约空间，选择这两个，然后选择GENERATE CODE

二、HAL_I2C_Mem_Write

I2C_HandleTypeDef *hi2c：I2C设备句柄

uint16_t DevAddress：目标器件的地址，七位地址必须左对齐

uint16_t MemAddress：目标器件的目标寄存器地址

uint16_t MemAddSize：目标器件内部寄存器地址数据长度

uint8_t *pData：待写的数据首地址

uint16_t Size：待写的数据长度

uint32_t Timeout：超时时间

返回值： HAL_StatusTypeDef ， HAL 状态（ OK ， busy ， ERROR ， TIMEOUT ）

向OLED写入命令的封装：

void Oled_Write_Cmd(uint8_t dataCmd)
{HAL_I2C_Mem_Write(&hi2c1,0x78,0x00,I2C_MEMADD_SIZE_8BIT,&dataCmd,1,0xff);
}

向 OLED 写数据的封装：最大的区别是目标器件的目标寄存器地址变成了0x40

void Oled_Write_Data(uint8_t dataData)
{
HAL_I2C_Mem_Write(&hi2c1,0x78,0x40,I2C_MEMADD_SIZE_8BIT,&dataData,1,0xff);}

三、初始化Oled（官方手册上面有）,清屏函数，调入图片的亮点到数组，显示函数。

初始化Oled:

void Oled_Init(void){
Oled_Write_Cmd(0xAE);//--display offOled_Write_Cmd(0x00);//---set low column addressOled_Write_Cmd(0x10);//---set high column addressOled_Write_Cmd(0x40);//--set start line address  Oled_Write_Cmd(0xB0);//--set page addressOled_Write_Cmd(0x81); // contract controlOled_Write_Cmd(0xFF);//--128   Oled_Write_Cmd(0xA1);//set segment remap Oled_Write_Cmd(0xA6);//--normal / reverseOled_Write_Cmd(0xA8);//--set multiplex ratio(1 to 64)Oled_Write_Cmd(0x3F);//--1/32 dutyOled_Write_Cmd(0xC8);//Com scan directionOled_Write_Cmd(0xD3);//-set display offsetOled_Write_Cmd(0x00);//Oled_Write_Cmd(0xD5);//set osc divisionOled_Write_Cmd(0x80);//Oled_Write_Cmd(0xD8);//set area color mode offOled_Write_Cmd(0x05);//Oled_Write_Cmd(0xD9);//Set Pre-Charge PeriodOled_Write_Cmd(0xF1);//Oled_Write_Cmd(0xDA);//set com pin configuartionOled_Write_Cmd(0x12);//Oled_Write_Cmd(0xDB);//set VcomhOled_Write_Cmd(0x30);//Oled_Write_Cmd(0x8D);//set charge pump enableOled_Write_Cmd(0x14);//Oled_Write_Cmd(0xAF);//--turn on oled panel	}

清屏函数

void Oled_Screen_Clear(void){char i,n;Oled_Write_Cmd (0x20);                    //set memory addressing modeOled_Write_Cmd (0x02);                    //page addressing modefor(i=0;i<8;i++){Oled_Write_Cmd(0xb0+i);               //éè??ò3μ??·￡¨0~7￡?Oled_Write_Cmd(0x00);                 //éè????ê??????aáDμíμ??·Oled_Write_Cmd(0x10);                 //éè????ê??????aáD??μ??·   for(n=0;n<128;n++)Oled_Write_Data(0x00); 			}	
}

设置图片的点阵,可以通过电脑画图软件画

通过取模软件生成数据将图片的亮点放到数组：

unsigned char bmpImager[] = {/*--  调入了一幅图像：E:\丁1.bmp  --*/
/*--  宽度x高度=128x64  --*/
0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,

显示函数：

void Oled_Show_Image(unsigned char *image)
{unsigned char i; unsigned int j;for(i=0;i<8;i++){Oled_Write_Cmd(0xB0 + i);//page0--page7//每个page从0列Oled_Write_Cmd(0x00);Oled_Write_Cmd(0x10);//0到127列，依次写入0，每写入数据，列地址自动偏移for(j = 128 * i; j<(128 * (i+1));j++){Oled_Write_Data(image[j]);}}
}

四、主函数

直接在while(1)循环之前添加即可。

//1. OLED初始化Oled_Init();//2. 选择一个位置//2.1 确认页寻址模式Oled_Write_Cmd(0x20);Oled_Write_Cmd(0x02);Oled_Screen_Clear();Oled_Show_Image(bmpImager);
