+//该程序使用了3个GPIO输入引脚和1个GPIO输出引脚，以及1个PWM通道。
+//
+//程序中定义了三个按钮的GPIO引脚，以及一个LED的GPIO引脚和PWM通道。然后在`app_main`函数中初始化GPIO和PWM，并创建三个GPIO中断处理函数分别处理三个按钮的按下和长按操作。
+//
+//对于按钮A和B，按下按钮时会逐步增加或减小LED的亮度，而长按按钮时，每500毫秒亮度会逐步减小或增加。对于按钮C，按下时切换LED的开和关。
+//
+//最后，在`app_main`函数中通过一个死循环让程序一直运行。
+//
+//请注意，本程序的实现可能与您的ESP32板的具体规格有关，需要根据您的板的规格进行调整。
