怎么实现基于STM32F103ZET6主控平台的设计？

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IIC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：
