I have not necessarily tried any of the products, software, advice, etc., but here are some links in case they help. Feel free to email me with comments or fuller reviews of anything you check out.
offers TCP/IP software, free for commercial or non-commercial use. It had a favorable comment on the LPC mailing list. Also, similar or related to above? http://www.sics.se/~adam/lwip.
is another source of Philips
NXP LPC ARM boards. I have the Tini2106 (formerly named TiniARM)
but have not tried it yet. It looks beautiful (and tiny). Their
Tini2131 at $37 (including $8 shipping, sales tax extra) looks
interesting also.
looks like a lot of good information about NXP (and other) ARM chips and also MMC/SD interfacing and GNU ARM tool chains for Windows.
This link has not been working for me for the past year or so. This is a fork, so to speak, of an earlier version of Riscy Pygness. It is licensed under the GNU GPL (unlike Riscy Pygness which is MIT/BSD). I gave my permission (not that it was necessarily needed). If the project is still active, please email me a better url.
