ENC28J60在51单片机上的移植（uIP0.9）的请教 其中电路图 程序是卖家送的。谢谢大家，有会
我现在是把卖家给的51的代码下载到STC89C516RD+中，能正常显示WEB SEVER的网页。其中51单片机与ENC28J60的连接接口定义在SPI.H中。我发现INT引脚好像并没有用到。而且WOL网络唤醒也没有用到。
（1）但是不稳定。不知道是不是没有时基的原因。因为我看程序中好像是直接延时完成的。
（2）而且不清楚怎么更改HTTPD.C中不同的网页对应的显示内容。这个里面是uIP0.9在51上的移植。希望懂的朋友给帮个忙啊。
我主要是想把DS18B20的温度上传到网页中。谢谢……
这里是卖家给的资料，全部放在这里供大家使用。
里面有电路图，程序（51 AVR STM32）ourdev_650945MVERES.rar(文件大小:1.89M) (原文件名:网络模块 卖家资料.rar)
其中51的程序、STM32程序我都测试通过。只不过 感觉都不太稳定，特别是51的基于uIP0.9的，感觉有点复杂。 好像判断网页与单片机控制的服务器通信的控制在这里面，但是不太清楚是怎么控制的。谢谢……

} 楼主，请问在连网时ping的是哪个ip是ping uipopt.h的UIP_IPADDR宏定义的那个ip吗？那个ip是自己设定还是必须是当前电脑的ip？我一直不知道到底ping哪个ip
