**enc28j60**
- 1 先把arduino 的IDE装好
- 2 下载EtherCard库文件【下载地址】
EtherCard is a driver for the ENC28J60 chip, compatible with Arduino IDE. Adapted and extended from code written by Guido Socher and Pascal Stang.
EtherCard是ENC28J60芯片的一种驱动，与Arduino的开发环境兼容。项目借鉴并扩展了Guido Socher与Pascal Stang的代码。

3 添加到Arduino IDE的开发库里面，重启Arduino程序就可以使用了
操作方式如图 - 4 连接arudino uno和enc28j60
PIN Connections (Using Arduino UNO):
VCC - 3.3V
GND - GND
SCK - Pin 13
SO - Pin 12
SI - Pin 11
CS - Pin 8 # Selectable with the ether.begin() function
最终连线图
- 5 设置一下本地网络以及arduino的网络，如果用192.168.1.0/24网段，最好把无线网先断了
