一.OLED的简单说明

0.96寸七针OLED:

  • CS:OLED片选信号;
  • RST(RES):硬复位OLED;
  • DC(RS):命令/数据标志(0,读写命令;1,读写数据)。

接线如下:D0,D1分别接SPI_CLK,SPI_MOSI

二.Cubemx的配置

三.根据时序图写驱动程序及自定义显示程序

驱动程序:

{				  
	if(cmd)
	{
		OLED_DC_Set();//命令/数据标志位置为1,则表示传送的是命令字节
	}
	  
	else
	  OLED_DC_Clr();//命令/数据标志位置为0,则表示传送的是数据字节		  
	  OLED_CS_Clr();//片选信号为低,表示选中OLED
	  HAL_SPI_Transmit_DMA(&hspi2,&dat,1);//oled.c文件唯一修改的地方,这里是利用了hal库提供的SPI传送函数
	  OLED_CS_Set();
	  OLED_DC_Set();	  
}

	OLED_WR_Byte(0XAF,OLED_CMD);  //DISPLAY ON
}
//关闭OLED显示
void OLED_Display_Off(void)
{

	OLED_WR_Byte(0X10,OLED_CMD);  //关闭电荷泵
	OLED_WR_Byte(0XAE,OLED_CMD);  //DISPLAY OFF
}
