I have started a new codeplex project called mip (managed Internet Protocol) to create a robust TCP/IP stack that is easy to use for .NET MicroFramework. Basically, if you have a .NET MF device with SPI support, you can now connect an enc28j60 based ethernet adapter to it without changing your firmware at all. That’s right, you can use the smaller firmware without ethernet and just add this library.
The basics are functional right now, but it has only been tested with a small sample web page and only with my 2-wire router. Please let me know if it works for you so I can check off different routers from the compatibility list. Also, if you have changes you want to make, please let me know! Or if you see it do something wrong, capture it with wireshark for me and send me the capture file…
Tested to work with ENC28 + CerbuinoBee
Also, tested with a generic enc28j60 module from ebay and the Cerb40. (wiring directions are in the intellisense tooltip of the enumeration in the Start method)
