arduino通过ENC28J60连接以太网

**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

• 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
