Anyody knows where I can buy an LPC3180 development board? I also need embedded linux for it with USB host and HID support, also I need the GNU C++ compiler for it that supports the co-processor built into the LPC3180. I been looking for weeks cant find none of those.I'm desperate, and need it immediately! please reply to nsmith@islandlogix.com Thanks
Wow you must be late on a project. Development always takes its due
time.

A development board for the LPC3180 cannot be trustworthy or tested.
Since the LPC3180 has never been manufactured and there arent any
samples available. I'm impatient for those too, I'll bet philips will
just be distributing their first batch as samples.

Start developing with the LPC2880 chips since they should be similar
enough (except for ARM7 instead of ARM9). I'm waiting for the Olimex
boards which should be next month. Also waiting for their L2290-8M
boards.

Even when they're out, you cant have them immediately.

digikey seems to have them http://www.digikey.com/scripts/DkSearch/dksus.dll?PName?Name=568-3242-ND&Site=US

Hmm, so that Nohau LPC-3000 board sitting on my co-worker's desk running his code must be a figment of my imagination, and the 138 pieces Digi- Key shows in stock must have been something I ate... --Gene
Wow, I stand corrected. The standardics.nxp.com site shows it as
planned instead of sampling.

I must not be on their favorite customer list.
