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:

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();
