Arduino框架下ESP32重启原因串口信息输出示例

Arduino框架下ESP32重启原因串口信息输出示例

---

当前示例代码编译基于固件版本：2.0.4

在程序开发初期debug是非常有必要的。用于排查和分析程序重启原因，从而改进和优化代码。

这里使用的程序烧录的板子型号为：ESP32C3

• 该程序示例可以在：C:\Users\Administrator\AppData\Local\Arduino15\packages\esp32\hardware\esp32\2.0.4\libraries\ESP32\examples\ResetReason路径下找到。
• 本示例不需要安装第三方库，但是需要引用对应的核心库当中的头文件才行。
