W5200如何连接入YEELINK啊？
小白一枚，不懂W5200的设置，UNO板和LM35，求大侠帮忙:(技术人员不在吗？？都休息了？ 请看下产品资料库，里面有相关介绍的啊。 和普通ethernet 一样用 ，换个库文件就好， 有样例的。
具体哪个地方有问题呢？ 我用测试教程里面的w5200 web server重新定义为一个server，板子正常，6路数据都可以内网显示，过一段时间将yeelink用w5100+uno的代码刷uno，可以连上jeelink，数据也有，但是过不了多久，就没有了，这是怎么回事？？w5200不能用w5100的代码库的吗？重新写的话，怎么写啊，太复杂了，我用的是LM35+UNO+W5200，本人小白一枚，大侠多多包容，感激不尽。 undead2003 发表于 2014-6-9 00:35

W5200的库和W5100是不一样的，只能向下兼容，产品页面或者wiki上都有下载的。
把圆来的给删了，换上新的就可以了 00000---基础小白求救，折腾好久了，没办法，基础不是差的问题，是空白，请求Grey大侠帮忙编写一下，红色部分LM35的代码：我根本就不懂呀，

Yeelink官方应该就有w5100和yeelink链接的样例程序和教程的吧？你试试直接用官方的资料。据我所知，对于w5200和w5100的差异其实主要是socket接口性能更强一些。所以arduino的库更新下，其他所有函数和功能都是完全兼容的！
1.建议先不要自己修改功能，使用官方样例
2.跑通后添加功能 lauren 发表于 2014-6-11 13:41

真的很奇怪，你的方法我也用过，不行，但是用官方的WEBSERVER来刷一次之后，再用YEELINK的样例程序就可以了，现在在测试能顶多久？？ 顶了10分钟，开始出现乱码，重新刷yeelink的样例程序，就恢复正常，还在看…… 奇怪了，为什么一定要刷一次这个webserver，然后Yeelink的样例也可以，自己写的代码也都可以了？？有技术人员吗？告知一二？ 反复尝试，发现DFrobot这块板子很有特点，一定要按照test程序里面的重新定义一下针脚才行，然后结合yeelink的上传程序就可以正常工作了，废话不说，代码如下：

?.哦？需要重新定义引脚？难道是nRST/nPWDN/nINT引脚和官方引脚不匹配？ lauren 发表于 2014-6-16 14:42

有这种可能性，WIKI里面就是需要重新定义引脚，但库里面大部分样例程序都没有定义引脚，这有点奇怪。
Anyway，感谢楼主分享经验！ undead2003 发表于 2014-6-12 20:48
