Arduino Mega2560 ENC28J60和RFID无法正常工作

Question

我是新来的，所以请不要为我的愚蠢而生气。 我有一个项目，我必须读取RFID UID代码（此部分的工作原理就像一个超级按钮），然后将其发送到连接到C＃应用程序的数据库，然后接收响应（0或1）。 我的问题（目前）是arduino不发送任何数据。 也许有人可以帮助我？

这是我的arduino代码：

我将EtherCard.h库和ENC28J60以太网模块用于arduino。

Answer 1

ENC28J60与Arduino UNO不兼容，与其他SPI设备一起使用时，很可能与MEGA2560不兼容。

您应该使用使用W5100的默认Arduino Ethernet Shield。

我遇到了与ENC28J60相同的问题，尝试了许多设置，最后得到了W5100，它可以使用默认的以太网库直接使用。
