我最近得到了一个arduino和wifi sheild，但我遇到了wifi库特别是udp类的问题。当我没有文件夹中的WiFiUdp.h和cpp文件时，连接和一切正常。我可以上网，发送数据，获得绿灯和蓝灯，建立连接和发送数据。但是当我在草图中包含wifiudp.h时，我收到了一堆错误。错误列在下面。我从github获取了我的库，下载了它，提取并将其填充到库中，就像我在github上做的其他一切一样。它不是我的代码，因为当我在arduino网站上使用wifisendreceive示例时，我上传它时会遇到相同的错误。某些东西在github的'master'arduino文件中无法正常工作。有没有人遇到过我正在处理的相同问题，有没有人知道如何解决这个问题？我知道尽可能多的错误，它可能不包括或定义某些东西，我只是不知道在哪里和什么。错误解释了它不工作的地方，但问题是它们中有很多。这是错误。感谢任何能够阐明这个udp课程的人。顺便说一句，这只是错误的一半。我不允许在体内发送超过3000个字符。错误是来自不同文件等的相同类型。

多重定义意味着您要么多次链接相同的符号，要么多次包含一个标题而没有正确的包含保护。在您的情况下，看起来您有一个WiFi和WiFi1文件夹包含相同的库链接（多次链接相同的符号）。 - 乔
