DMA控制见【0.96寸 OLED屏实现1500Fps的帧率】STM32 软件、硬件SPI、I2C驱动总结

OLED SPI 端口定义

本节引自STM32驱动0.96寸OLED液晶屏(12864液晶屏) —— 小牧同学
在这里插入图片描述
两种屏幕的引脚数不一样,左边的有7个引脚,而右边的只有6个。其次,端口的标号也不完全一样,第一个分别标为GND,VCC,D0,D1,RES,DC和CS第二个分别标为GND,VCC,SCL,SDA,RST,D/C。

七针OLED引脚定义


GND — 接地端口
VCC — 接3.3V电源端口
D0 — CLK时钟信号(等同于上面的SCL)
D1 — 数据端口(等同于上面的SDA)
RES — 复位端口(等同于上面的RST)
DC — 数据/命令选择引脚(等同于上面的D/C)
CS — 片选引脚(低电平有效,也就是所需要接低电平,我实际试验过不接该引脚也是可以正常使用的)

六针OLED引脚定义


GND — 接地端口
VCC — 接3.3V电源端口
SCL — CLK时钟信号端口
SDA — MOSI数据端口
RST — 复位端口
D/C — 数据/命令选择引脚
