Wondering if anyone has any recommendations for a good TCP/IP stack.
I just assumed that if we switched to an ARM processor, there would be 
lots of stacks available, but I'm not finding many.

Several I've looked at are in the $10K range (very nicely done I'm 
sure, but too expensive for a small project).  Several embedded stack 
companies are now out of business also...

Main requirements are to support as many TCP levels as possible, in a 
minimal amount of RAM...for something under $1K.

Thanks in advance!

Generally I'd say that TCP/IP stacks would be written mainly in C and 
thus CPU neutral. Have a grub around various LGPL and similar 
offerings. With LPC21xx, your biggest worry is probably going 
to be keeping the RAM footprint small. Look at http://dunkels.
com/adam/uip/size.html which has been crafted for small size.

I agree. Look at uIP, it took me less than a sunday afternoon to port it to an eZ80 board with a CS8900 controller. And I didn't have the driver for CS8900. My experience was very good with uIP 0.6; meanwhile 0.9 was released and it fixed some bugs that I have to fix myself in the 0.6 version (yes, this also happened in the same afternoon). So give it a try, I don't think you'll regret it.

I only know it, have not used it yet.

Try LwIP on top of uCOS-II.

You can find ARM ports for uCOS-II on my site; and
also uCOS_LwIP port.

Hope this is helpful!

You can buy the book!

There is an excellent text "TCP/IP lean" available from amazon.com. It's really clear and easy to read.

It contains and describes code for all the layers, and decribes a small web server for the pic (hey! thats go to be a small foot print) 

The book comes with a CD of the source code.

It is missing PPP code, but this can be downloaded. I have PPP for the pic that i could email you

Subject: Looking for TCP/IP stack

Wondering if anyone has any recommendations for a good TCP/IP stack.
I just assumed that if we switched to an ARM processor, there would be 
lots of stacks available, but I'm not finding many.

Several I've looked at are in the $10K range (very nicely done I'm 
sure, but too expensive for a small project).  Several embedded stack 
companies are now out of business also...

Main requirements are to support as many TCP levels as possible, in a 
minimal amount of RAM...for something under $1K.

Thanks in advance!

Thanks for the heads up on this!  And of course no good deed goes 
unpunished, maybe you could answer another question...

Just wondering how the uIP (or LWIP?) compares to the stack that came 
with the eZ80 board - (I thought their stack was complete and free to 
use, full blown stack etc...)

We are also looking at using a eZ80 instead of the Phillips ARM part..
Any thoughts on the eZ80 would be Greatly appreciated (I don't like 
eZ80 parts myself, but could use some justification other than 
personal preference :)

Thanks!
Ralph

It's quite simple really, I only had the board and the C compiler, not the TCP/IP stack. The eZ80 is a nice processor, but it's no match for an ARM IMHO. If you're not set on the ARM, why don't you try the DS80C400 from Maxim? You get quite a decent stack on the chip itself...

Yes, I purchased TCP/IP Lean, and got the "embedded" stack running in 
DOS  (and I wrote a PPP interface for it too :(.  However, this stack 
does very little error handling, no references to RFCs, no support for 
out of sequence packets and no real socket interface.

As I found several bugs just playing with one connection, I am not 
comfortable with the code.  With no support and no upgrades (I did 
purchase the add-on WiFi module) and no forum to improve the code, it 
is little more than a science project with a book attached...

I am looking forward to working with the LwIP or uIP as these appear 
to be comprehensive stacks and they have an open source environment...

Thanks,
Ralph

Wiznet (www.wiznet.co.kr)is manufacturing TCP/IP stack IC W3100A.I2C 
interfacing feature is also available .you can interface this to 
LPC210X I2C pin

The problem with solution like the one from Wiznet is that they can 
dissappear tommorow (remember Seiko S7600). When you make a choice 
between software and hardware stack have it in mind.
