延时函数：

/**************OLED驱动程序用的延时函数****************/
void Delay_nms(uint nms)  //延迟函数{uint i,j;for (i=0;i<nms;i++){for(j = 0;j<MCLK/4000;j++);}}

I2C初始化，并包含引脚初始化：

void I2C_Init()                   //I2C初始化{CLK_PCKENR1 |=0x01;          //使能I2C外设时钟PB_DDR &= 0x30;             // 把PB4、PB5设置为低速率开漏输出模式。原来的是  0xcf  30PB_CR1 &= 0xcf;             //PB_CR2 &= 0xcf;             //I2C_CR1 = 0x00;             //禁用I2C模块I2C_FREQR = 0x10;           //输入时钟频率为16MHzI2C_TRISER = 0x11;          //0x10+1I2C_OARH = 0x40;            //七位地址模式I2C_OARL = 0xa0;            //自身地址0xa0I2C_CCRL = 0x50;            //  16M/ 100k/ 2I2C_CCRH = 0x00;            //  标准模式I2C_CR1 = 0x01;             //I2C使能}

I2C写操作（一个字节）：

void I2C_Write_Byte(uchar DeviceAddress,uchar Address,uchar Data){//uchar temp =0; while ((I2C_SR3 & 0x02)!= 0);       // 等待I2C总线空闲  位1：1是总线上有通信I2C_CR2=0x01;                         //while ((I2C_SR1 & 0x01)== 0);        // EV5,起始信号已经发送I2C_DR=(DeviceAddress & 0xfe);       //发送从器件物理地址，最低为0，写操作while ((I2C_SR1 & 0x02)== 0);        //地址已经被发送temp = I2C_SR1;temp = I2C_SR3;while ((I2C_SR1 & 0x80)== 0);        //  等待发送寄存器为空I2C_DR = Address;                    //发送要写入的寄存器地址while ((I2C_SR1 & 0x04)== 0);        //等待发送完成while ((I2C_SR1 & 0x80)== 0);         //等待发送寄存器为空I2C_DR = Data;                      //发送要写入的数据while ((I2C_SR1 & 0x04)== 0);       //等待发送完成temp = I2C_SR1;                     //清零BTF标志位temp = I2C_DR;I2C_CR2=0x02;}

OLED写命令：

void OLED_WrCmd(uchar cmd)    {I2C_Write_Byte(0x78,0x00,cmd); }

OLED写数据：

void OLED_WrDat(uchar Data)    {//  只需要调用这个就可以I2C_Write_Byte(0x78,0x40,Data)I2C_Write_Byte(0x78,0x40,Data);}

OLED 设置坐标：

void OLED_Set_Pos(unsigned char x, unsigned char y)
{ OLED_WrCmd(0xb0+y);OLED_WrCmd(((x&0xf0)>>4)|0x10);//把变量X的高4位移到低4四位去，且和0x10取或运算（这里可看成+16）OLED_WrCmd((x&0x0f)|0x01);      //把变量X的值取低4位，且与0x01取或运算（最低位始终为1）
}

OLED全屏：

void OLED_Fill(unsigned char bmp_dat)
{unsigned char y,x;for(y=0;y<8;y++){OLED_WrCmd(0xb0+y);OLED_WrCmd(0x01);OLED_WrCmd(0x10);for(x=0;x<X_WIDTH;x++)OLED_WrDat(bmp_dat);}
}

OLED复位清屏：

void OLED_CLS(void)
{unsigned char y,x;for(y=0;y<8;y++){OLED_WrCmd(0xb0+y);OLED_WrCmd(0x01);OLED_WrCmd(0x10);for(x=0;x<X_WIDTH;x++)OLED_WrDat(0);}
}

OLED初始化：

void OLED_Init(void)
{Delay_nms(500);//初始化之前的延时很重要！OLED_WrCmd(0xae);//--turn off oled panelOLED_WrCmd(0x00);//---set low column addressOLED_WrCmd(0x10);//---set high column addressOLED_WrCmd(0x40);//--set start line address  Set Mapping RAM Display Start Line (0x00~0x3F)OLED_WrCmd(0x81);//--set contrast control registerOLED_WrCmd(Brightness); // Set SEG Output Current BrightnessOLED_WrCmd(0xa1);//--Set SEG/Column Mapping     0xa0左右反置 0xa1正常OLED_WrCmd(0xc8);//Set COM/Row Scan Direction   0xc0上下反置 0xc8正常OLED_WrCmd(0xa6);//--set normal displayOLED_WrCmd(0xa8);//--set multiplex ratio(1 to 64)OLED_WrCmd(0x3f);//--1/64 dutyOLED_WrCmd(0xd3);//-set display offset   Shift Mapping RAM Counter (0x00~0x3F)OLED_WrCmd(0x00);//-not offsetOLED_WrCmd(0xd5);//--set display clock divide ratio/oscillator frequencyOLED_WrCmd(0x80);//--set divide ratio, Set Clock as 100 Frames/SecOLED_WrCmd(0xd9);//--set pre-charge periodOLED_WrCmd(0xf1);//Set Pre-Charge as 15 Clocks & Discharge as 1 ClockOLED_WrCmd(0xda);//--set com pins hardware configurationOLED_WrCmd(0x12);OLED_WrCmd(0xdb);//--set vcomhOLED_WrCmd(0x40);//Set VCOM Deselect LevelOLED_WrCmd(0x20);//-Set Page Addressing Mode (0x00/0x01/0x02)OLED_WrCmd(0x02);//OLED_WrCmd(0x8d);//--set Charge Pump enable/disableOLED_WrCmd(0x14);//--set(0x10) disableOLED_WrCmd(0xa4);// Disable Entire Display On (0xa4/0xa5)OLED_WrCmd(0xa6);// Disable Inverse Display On (0xa6/a7) OLED_WrCmd(0xaf);//--turn on oled panelOLED_Fill(0x00); //初始清屏OLED_Set_Pos(0,0);
}

功能描述：显示8*16组标准ASCII字符?? 显示的坐标（x,y），y为页范围0～7

void OLED_P8x16Str(uchar x, uchar y, char ch[])   //8x16的字符串
{unsigned char c=0,i=0,j=0;while (ch[j]!='\0'){c =ch[j]-32;if(x>120){x=0;y++;}OLED_Set_Pos(x,y);for(i=0;i<8;i++)OLED_WrDat(F8X16[c*16+i]);OLED_Set_Pos(x,y+1);for(i=0;i<8;i++)OLED_WrDat(F8X16[c*16+i+8]);x+=8;j++;}
