错误信息：'PinNumber' was not declared in this scope 解决方法：这个错误通常出现在变量名或者函数名没有正确定义的情况下。请检查你的代码，确保变量名和函数名都已正确声明并且没有拼写错误。错误信息：'serial' was not declared in this scope 解决方法：这个错误通常出现在你使用了串口通信的情况下

问如何处理Arduino中M5Stack库抛出的编译错误EN在程序运行的过程中，如果发生了错误，可以事先约定返回一个错误代码，这样，就可以知道是否有错，以及出错的原因。在操作系统提供的调用中，返回错误码非常常见。比如打开文件的函数open()，成功时返回文件描述符（就是一个整数），出错时返回-1。
Compilation error: 'WiFi' was not declared in this scope Other Steps to Reproduce Attempting to verify or upload the code returns the error. Reverting to previous versions, such as 2.0.14 stops this issue from happening, but ESP32-H2 is not supported in this version. Even the earliest versi...
