C++ 别针赢了'；t设置为高，Wemos ESP8266
我正在处理一个小问题：当我尝试将引脚0设置为高电平时，它没有响应。我通过web界面控制引脚：。 我已经检查过了，根本没有电压，我已经尝试过使用其他引脚，没有成功。我想这个bug在我的代码中，特别是在INL1中。当我通过另一个脚本（TESTscript）手动将pin设置为high时，它的响应良好 正常代码：C++ 别针赢了'；t设置为高，Wemos ESP8266,c++,c,esp8266,C++,C,Esp8266,我正在处理一个小问题：当我尝试将引脚0设置为高电平时，它没有响应。我通过web界面控制引脚：。 我已经检查过了，根本没有电压，我已经尝试过使用其他引脚，没有成功。我想这个bug在我的代码中，特别是在INL1中。当我通过另一个脚本（TESTscript）手动将pin设置为high时，它的响应良好 正常代码： #include <ESP8266WiFi.h> const char* ssid = "RCwifiModule"; const char* pass

或者使用此链接：如果您尝试用草图使该引脚处的led闪烁？@Juraj它可以工作，问题具体在inl1中，然后创建一个最小的示例problem@Juraj我真的不知道问题出在哪里。Viable INL1对任何事情都没有响应。即使管脚更改或将名称INL1更改为INLeft.INL1也不是常量，它无法响应任何内容。
