古鲁冥想错误: ESP32上的核心1恐慌(禁止加载)
因此，我试图创建一个网络服务器，用一个ESP32点亮多个LED。当按下按钮时，服务器将发送一个GET请求。这是以前的工作，只有一个LED和一个按钮的HTML页面。这段代码就是，只要有更多的按钮和变量。但是，当我将它上传到ESP32并打开串行窗口时，我得到如下信息：

我不知道这意味着什么或者我做错了什么。我试过：
1-最小化变量(在变量的前缀中添加无符号、const等)
2-将变量放入局部函数的作用域
有人能帮忙吗？如果你愿意的话，我会非常感激的。(我对Arduino编程完全陌生，所以我不知道该怎么做)。下面是代码：

你使用的是GPIO引脚连接到ESP32 32的闪存芯片。当你用pinMode()重新编程的时候，你会干扰ESP32 32读写闪存的能力，它就会崩溃。
const unsigned int outputfw = 2;
const unsigned int outputlt = 4;
const unsigned int outputrt = 7;
const unsigned int outputbw = 6;引脚6和7连接到SPI闪存芯片。它们在应用程序中通常是不安全的。它们通常也不表达在ESP32的突破板上。
试着用13和14这样的安全引脚来重建固件，而不是6和7，你会发现它不会像它那样崩溃。
也许你把突破板的密码和GPIO的密码搞混了？为了找到正确的GPIO引脚，你需要参考板的插脚。ESP32 Arduino代码指的是GPIO引脚号，而不是插板引脚号。
对于如何使用ESP32 GPIO引脚以及哪些引脚是安全的，这里有一个非常有用的参考。
