ESP32点亮0.96寸LED

考虑在上一篇的写那个项目中添加一个屏幕的显示，OLED屏幕为淘宝购买的6针型号蓝绿双色的屏幕，通过四线SPI与ESP32连接。

OLED屏电路图

OLED实物图

这是连接好运行后的图，有点乱。

OLED与ESP32连线方式

其中oled.h中有关于管脚的定义，可以查看。

程序实现

程序参考的是淘宝老板发送例程中的C51程序，修改下就能运行，使用的是SDK为ESP-IDF4.2，在examples/get-start/hello_world例子。在Linux下面编译，下面为具体的代码。

编译时需要在main文件目录下的CmakeLists.txt文件中添加需要的c文件

idf_component_register(SRCS "hello_world_main.c""oled.c"  #添加需要编译的文件INCLUDE_DIRS "")

在Linux环境下，通过idf.py build编译后，使用idf.py -p /dev/ttyUSB0 flash命令就能烧写到ESP开发板。
