OLED的驱动分析一下：

void OLED_Init(void)
{
OLED_RST=0;
DelayMs(50);
OLED_RST=1;    //从上电到下面开始初始化要有足够的时间，即等待RC复位完毕

OLED_WrCmd(0xae);//--turn off oled panel
OLED_WrCmd(0x00);//---set low column address
OLED_WrCmd(0x10);//---set high column address
OLED_WrCmd(0x40);//--set start line address  Set Mapping RAM Display Start Line (0x00~0x3F)
OLED_WrCmd(0x81);//--set contrast control register
OLED_WrCmd(Brightness); // Set SEG Output Current Brightness
OLED_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 display
OLED_WrCmd(0xa8);//--set multiplex ratio(1 to 64)
OLED_WrCmd(0x3f);//--1/64 duty
OLED_WrCmd(0xd3);//-set display offset  Shift Mapping RAM Counter (0x00~0x3F)
OLED_WrCmd(0x00);//-not offset
OLED_WrCmd(0xd5);//--set display clock divide ratio/oscillator frequency
OLED_WrCmd(0x80);//--set divide ratio, Set Clock as 100 Frames/Sec
OLED_WrCmd(0xd9);//--set pre-charge period
OLED_WrCmd(0xf1);//Set Pre-Charge as 15 Clocks & Discharge as 1 Clock
OLED_WrCmd(0xda);//--set com pins hardware configuration
OLED_WrCmd(0x12);
OLED_WrCmd(0xdb);//--set vcomh
OLED_WrCmd(0x40);//Set VCOM Deselect Level
OLED_WrCmd(0x20);//-Set Page Addressing Mode (0x00/0x01/0x02)
OLED_WrCmd(0x02);//
OLED_WrCmd(0x8d);//--set Charge Pump enable/disable
OLED_WrCmd(0x14);//--set(0x10) disable
OLED_WrCmd(0xa4);// Disable Entire Display On (0xa4/0xa5)
OLED_WrCmd(0xa6);// Disable Inverse Display On (0xa6/a7)
OLED_WrCmd(0xaf);//--turn on oled panel

OLED_Fill(0x00);  //初始清屏
OLED_SetPos(0,0);
}
