* UIPEthernet EchoServer example.
|
|
*
|
|
* UIPEthernet is a TCP/IP stack that can be used with a enc28j60 based
|
|
* Ethernet-shield.
|
|
*
|
|
* UIPEthernet uses the fine uIP stack by Adam Dunkels <adam@sics.se>
|
|
*
|
|
* -----------------
|
|
*
|
|
* This Hello World example sets up a server at 192.168.1.6 on port 1000.
|
|
* Telnet here to access the service. The uIP stack will also respond to
|
|
* pings to test if you have successfully established a TCP connection to
|
|
* the Arduino.
|
|
*
|
|
* This example was based upon uIP hello-world by Adam Dunkels <adam@sics.se>
|
|
* Ported to the Arduino IDE by Adam Nielsen <malvineous@shikadi.net>
|
|
* Adaption to Enc28J60 by Norbert Truchsess <norbert.truchsess@t-online.de>
