求助加载第三方库一调用就报错无法编译

RT，有没有大佬知道这是什么情况

在百度上找了一上午也没有成果

把库初始化一下在编译！

ChenRuiStudent

请问解决了吗   我也是遇到了同样的问题，怎么初始化库

库有问题，你换个库就行了

意思是i2c错误，库没有引用，管脚没有设置，实体没有开始。
库不能这样只写一句include的，IDE的报错告诉你：年轻人要讲武德！

我这个错误是怎么回事,不知道哪里出问题了

"WiFi.h" 对应多个库
已使用： D:\Program Files (x86)\arduino1\hardware\espressif\esp32\libraries\WiFi
未使用：D:\Program Files (x86)\arduino\libraries\WiFi
exit status 1
为开发板 ESP32F 编译时出错。

提示这两个库spi赋值要求。

"WiFi.h" 对应多个库，把后面一个删了。

不知道怎么搞赋值，我可以把这几个ino文件发给你，麻烦你给我跑出来对应的bin文件可以吗？感谢。QQ:1491001066

你好，哥哥，麻烦有空的话可以给我那几个ino 文件编译一下吗，编译成bin文件就行，感谢
