Thoses sketchs for the arduino enables you to send it DMX in art-net. You can send 512 channels from VVVV thruth the DMX (art-net Sender) node.

This works with Duemillanove and UNO, on Arduino 22 software.

Contents:

• art-net receiver.pde wich analyse if packets received are really art-net. see the universe, opcodes. Store in a buffer_dmx values. Up to you to do what you want with it.

• art-net receiver RAW.pde doesn't analyse anything. Just store the incoming packet as if it was an art-net packet. Dangerous if you use it in non closed and very controlled network.

• art-net et tlc.pde wich enable you to use a TLC5940NT to increase heavely number of output dimmable you can have on your UNO.

TLC5940 has 14 output and is daisy chainable. Unfortunately, use of Ethernet Shield and TLC on a same arduino board is physically conflicting.
For this a hack of the headers in the arduino core header, the ethernet library, and the TLC library.
Wiring is changed from the usually wiring you may find around.
An html doc ( in french and english ) is included in the folder.
This hack is Tofe86 arduino's contribution on the topic of ethernet / TLC conflict.

Just done a little test with my whitecat here:
