Hello,

I'm a newbie to this newsgroup and the LPC21xx.

I plan to port the Ethernut (www.ethernut.de) OS/stack to the 
LPC2116. Before I start I was wondering whether anybody has already 
started this exercise?

The Ethernut OS has already been ported to a Samsung based ARM, I was 
going to use this as a starting point. 

Many thanks,

Lee

Not me, But I don't think there's a device called LPC2116!? 
You should consider an external memory map processor LPC22xx when
interfacing to "memory based" components ... for more overall speed...

Properly not a bad idea

Many thanks,

Ah.. Sorry I meant the LPC2114, I was also considering the LPC2214 to 
allow for future larger memory requirements.

We're currently porting our PowerNet stack to LPC2106. PowerNet 
includes multi-threaded Telnet and HTTP/web servers. With an 
external Ethernet chip it all fits in about 100k of code. I'll 
report the final figures and performance when it's finished.

So the conclusion is that you can use a single chip for this 
kind of job. External serial EEPROM or DataFlash is probably a 
good idea for web page storage.
