This is UIPEthernet version 1.59
An plugin-replacement of the stock Arduino Ethernet library for ENC28J60 shields and breakout boards. Full support for persistent (streaming) TCP-connections and UDP (Client and Server each), ARP, ICMP, DHCP and DNS.
Just include 'UIPEthernet.h' instead of 'Ethernet.h' and use all your code written for the stock Arduino Ethernet lib!
UIPEthernet is written as a wrapper around the mature uIP Stack by Adam Dunkels, which provides the low-level implementation for all supported protocols. To overcome the memory-constrains (a 'regular' uIP-application does all processing in RAM) the ENC28J60 internal memory is used for all stream buffers (in and out). Only 400-600 Bytes of Arduinos RAM are used (depending on the number of concurrently open connections). As of Flash-memory a ATmega368-based Arduino is the minimum requirenment.
This library is written by Norbert Truchsess <norbert.truchsess@t-online.de>
uIP was written by Adam Dunkels of the Networked Embedded Systems group at the Swedish Institute of Computer Science.
This library was inspired by the SerialIP implementation by Adam Nielsen <malvineous@shikadi.net>, actually I took this code as a starting point, but in the latest versions there are very few lines left.
Installation
------------
To install the libraries, you need to place them into your "libraries" folder. You can find it within your Arduino IDE distribution within the "hardware" folder.
C:\> cd [path to Arduino distribution]\libraries
C:\> git clone https://github.com/ntruchsess/arduino_uip UIPEthernet
Be sure to restart the IDE if it was running.
On a Mac, you will want to create a folder named "libraries" in in the "Documents" -> "Arduino" folder within your home directory. Clone the project there (and restart the IDE, if it was running during this process).
$ cd ~/Documents/Arduino/libraries
$ git clone https://github.com/ntruchsess/arduino_uip UIPEthernet
Or you download the zipped version of the library from https://github.com/ntruchsess/arduino_uip/releases, and copy the contained directory UIPEthernet to [path to Arduino distribution]\libraries\UIPEthernet.
If you are running Arduino-IDE 1.5.x use release-version 1.59 or checkout branch 'Arduino_1.5.x'
Additional information can be found on the Arduino website: http://www.arduino.cc/en/Hacking/Libraries

Advanced Chat Server
A simple server that distributes any incoming messages to all
connected clients but the client the message comes from.
To use telnet to your device's IP address and type.
You can see the client's input in the serial monitor as well.
Using an Arduino Wiznet Ethernet shield.
Circuit:
* Ethernet shield attached to pins 10, 11, 12, 13
* Analog inputs attached to pins A0 through A5 (optional)

* NOTE: UDP is fast, but has some important limitations (thanks to Warren Gray for mentioning these)
* 1) UDP does not guarantee the order in which assembled UDP packets are received. This
* might not happen often in practice, but in larger network topologies, a UDP
* packet can be received out of sequence.
* 2) UDP does not guard against lost packets - so packets *can* disappear without the sender being
* aware of it. Again, this may not be a concern in practice on small local networks.

Digital Pot Control
This example controls an Analog Devices AD5206 digital potentiometer.
The AD5206 has 6 potentiometer channels. Each channel's pins are labeled
A - connect this to voltage
W - this is the pot's wiper, which changes when you set it
B - connect this to ground.
The AD5206 is SPI-compatible,and to command it, you send two bytes,
one with the channel number (0 - 5) and one with the resistance value for the
channel (0 - 255).
The circuit:
* All A pins of AD5206 connected to +5V
* All B pins of AD5206 connected to ground
* An LED and a 220-ohm resisor in series connected from each W pin to ground
* CS - to digital pin 10 (SS pin)
* SDI - to digital pin 11 (MOSI pin)
* CLK - to digital pin 13 (SCK pin)

* The MySensors Arduino library handles the wireless radio link and protocol

* The sensors forms a self healing radio network with optional repeaters. Each
* repeater and gateway builds a routing tables in EEPROM which keeps track of the
* network topology allowing messages to be routed to nodes.

*
*
* DESCRIPTION
* The EthernetGateway sends data received from sensors to the ethernet link.
* The gateway also accepts input on ethernet interface, which is then sent out to the radio network.
*
* The GW code is designed for Arduino 328p / 16MHz. ATmega168 does not have enough memory to run this program.
*
* LED purposes:
* - To use the feature, uncomment WITH_LEDS_BLINKING in MyConfig.h
* - RX (green) - blink fast on radio message recieved. In inclusion mode will blink fast only on presentation recieved
* - TX (yellow) - blink fast on radio message transmitted. In inclusion mode will blink slowly
* - ERR (red) - fast blink on error during transmission error or recieve crc error
*
* See http://www.mysensors.org/build/ethernet_gateway for wiring instructions.
