利用stm32f103的SPI1和OLED屏连接。引脚连接:
            DC-----------PE0
            RST----------PE1
            SCL----------PA5
            SDA----------PA7
关键SPI配置代码：
         /* SPI1 Config -------------------------------------------------------------*/
      SPI_InitStructure.SPI_Direction = SPI_Direction_2Lines_FullDuplex;
      SPI_InitStructure.SPI_Mode = SPI_Mode_Master;
      SPI_InitStructure.SPI_DataSize = SPI_DataSize_8b;
      SPI_InitStructure.SPI_CPOL = SPI_CPOL_Low;
      SPI_InitStructure.SPI_CPHA = SPI_CPHA_1Edge;
      SPI_InitStructure.SPI_NSS = SPI_NSS_Soft;
      SPI_InitStructure.SPI_BaudRatePrescaler = SPI_BaudRatePrescaler_16;
      SPI_InitStructure.SPI_FirstBit = SPI_FirstBit_MSB;
      SPI_InitStructure.SPI_CRCPolynomial = 7;
      SPI_Init(SPI1, &SPI_InitStructure);
      /* Enable SPI1 */
      SPI_Cmd(SPI1, ENABLE);

试了试16*16和32*32汉字点阵都能成。
