我试图用我的 ESP32 做一个“家庭重量”并使用 IBMCloud 显示值,但是我遇到了 Arduino IDE 和我的代码的一些问题。
我收到此错误:
Arduino:1.8.5(Windows 10),Tarjeta:“ESP32 开发模块,QIO,80MHz,4MB(32Mb),921600,无”
C:\Users\XX\Documents\Arduino\IBM_Watson_Connect\IBM_Watson_Connect.ino:8:25:致命错误:ESP8266WiFi.h:没有这样的文件或目录
编译终止。
退出状态 1 ESP32 开发模块卡的编译错误。
我正在使用 ESP32 开发板。我的代码是这样的:

}
有些地方提到缺少库,未正确选择板,未更新库..我都检查了.. Arduino已更新,库已安装和更新,选择了正确的板(我实际上有尝试了所有其他与 Esp32 相关的板,结果相同)
