Now they tell me! What I learned AFTER the enc28j60 hack-a-rama
David schultz on the cosmac elf web site commented that 1400 lines was a lot of code for my ping example and that the wiznet-based arduino shields did a lot more of the work for ethernet attachment. He provided a link to what woud be a much simpler starting point for getting an 1802 on the net. It’s code for an avr to use a wiznet based shield – it’s much simpler and more compact and it’s all in one file rather than broken into a bunch of libraries and classes. If I had realized how much simpler this would have been with wiznet I would have sprung for the more expensive module. I might still get one to play with but frankly, the 200-300 ma the ethernet modules use seems prohibitive and i’d rather leapfrog to wifi if i can find one similar.
The code and discussion are at http://www.seanet.com/~karllunt/w5100_library.html
and there’s hardware at at http://www.robotshop.com/seeedstudio-wiznet-ethernet-arduino-shield.html
The Seeed stuio shield actually looks pretty good – there would be room to put some extra female headers for interfacing.
