基于STM32F103ZET6主控平台实现(SPI接口)OLED液晶屏驱动
2024-04-10 04:22:31
一个热爱代码的工程师，唯有凭借双手不断敲打，才可以快速提升实力！
本文谨以记录，日后相忘时再作复习，代码没有贵贱，既来之则安之。
OLED液晶屏产品图和效果图
由上图我们知道：OLED液晶屏分别有GND VCC SCL SDA RES DC 六个引脚接口
通信协议：OLED与STM32的通信是基于SPI协议
引脚连接：
查阅STM32F1的原理图得知OLED/CAMARA接口引脚定义
-->
-->
-->
-->
结合原理图和OLED的六个引脚可以推算出：
GND ---- GND
VCC ---- PD3
SCL ---- PG13
SDA ---- PC0
RES ---- PC2
DC ---- PC4
连接好后开始编写代码：
