RE: [cosmacelf] Olduino ethernet success
- you're right david, the wiznet seems to do a lot more. I went with the module I chose because it was $10 and the smaller form factor seemed like it would be easier to adapt to the olduino. I am a big fan of the spi serial bus so i was happy the enc supported that. In the end it was a gratifyingly hack-y thing to do and i don't regret my choice(much). I'll keep plugging at this thing til I hit a wall. If you get something going with the wiznet maybe we can link them up.

The W5100 takes care of many details with built in IP, TCP, and UDP. I
haven't written any code for it yet but I did Google up an example:
One thing I liked about it is it has a memory mapped interface (32K)
that would be a lot faster on an 1802 than serial.
