国庆假期即将结束,回顾这些天的休息调整,今天拿出来STM32G4 NUCLEO G431RB板子,结合之前工程资料,点点OLED屏。之前发了提问贴,谢谢各位网友的鼎力相助,Keil在线下载提示内部命令错误是Keil版本的原因导致,所以重新安装了5.28的版本,并安装了板极间支持包,底层标准接口动态库,然后很顺利的就实现了在线下载、调试。本来原计划9月份下旬点亮手中的OLED屏的,但是手头的OLED模块不知道什么原因,一接通G4NUCLEO31RB的VCC,模块的屏与FPC连接的地方烫手,然后拿到其他开发板上验证,确定是OLED模块已经短路破损,然后在淘宝上淘了一块OLED模块,今天拿出来来调试调试这个模块。( o* r P; O4 A; {+ `% E$ y) e- r: j
模块是采用IIC的接口,所以结合基于STM2G431RB的原理图,将SCL连接上GPIOB8,SDA连接上GPIOB9# f$ N( H4 d+ N( |8 t8 H
