EtherCard
The EtherCard library implements a network driver for the Ether Card board. It is derived from code by Guido Socher and Pascal Stang, and hence licensed as GPL2. Includes an "etherNode.pde" webserver demo.
Starting with Arduino IDE 1.0beta2, the source code and and issue tracker have moved to GitHub.
For the Arduino IDE 0022, download as ZIP archive, and put the "EtherCard" folder inside a "libraries" folder next to your sketches.
