'[PIC] Microchip TCPIP Stack is a lot!'

Hello,

    I'm porting one application I've developed using a PIC18 and an
RTL8019AS to a new platform.

    This new platform uses a dsPIC (right now, a dsPIC33FJ12MC202) and
an ENC28J60.

    I'm studying Microchip's TCPIP stack and I'm founding it overly
complex for this task. I just need basic Ethernet protocols (ARP,
PING/ICMP) and UDP for data transmission/reception. I've done this with
minimal code using the RTL8019.

    Microchip's ENC28J60.c seens to have all the functions I need for
basic acess. ARP, ICMP, UDP etc I can implement on my own way (simple,
direct to the point and fast routines) but it uses a lot of snippets
that's on another files and I'll have a big job sorting what I need and
what I don't.

    Someone here have already done this? Using just ENC28J60.c (and
ENC28J60.h) and the necessary supporting code from other files?

    Any alternatives? I would preffer not to reinvent the wheel. If you
already have done something I can use but preffer not to give it free,
we can negotiate the rights to use it.

    Thank you all and best regards,

    Brusque

I've used the Microchip TCP/IP stack on both 24H and 18F chips without too
much trouble. I just include the files I think I'll need in the project.
When the compiler complains about something missing, I add that file to
the project. I think it's possible to include a good subset of all the
files for limited functionality. In my case, I'm using DHCP, my own TCP
protocol, HTTP2 and MCPFS2 (I think that's the name of it... it's their
file system for web pages). Remember also to look in the utilities
directory for a program to generate the tcp configuration files. It saves
a lot of work.

Good luck!

Harold

    that was a good sugestion. Thanks.

    Last friday, I've spent all day dealing with the TCP/IP stack and
have managed to use it with my setup. Then I've removed most of the
things I don't need and now I have my hardware working and a starting
firmware to work with.

    We've been thinking about using Davicom's DM9003 or Micrel's
KSZ8842-16MQL in some new gadgets. These devices seens amazing and I'm
trying to get some evaluation boards.

    I'm also looking for someone who have experience with those devices
(or others with integrated switchers). I'm willing to pay for someone to
write the low-level routines for us.

    Best regards,

    Brusque

Edson, I think I mentioned earlier on this list that I've used a
KS8995.  I'm curious why you would choose a part (KSZ8842-16MQL) with
an 8/16bit bus i/f rather than one with SPI/I2C?

Alex
