Lpc2000

Hi all,

Since there are a bunch of knowledgable microcontroller
and Linux developers that read this list, I want to
describe a concept and see if anyone has developed
parts.

I want to look into connecting devices using networking
interfaces. In some cases the 'network' will be a
simple point-to-point link using a serial port (PLIP)
or the parallel port (PLIP), or a real network controller
(eg. like the CS8900's on the Olimex boards and others).

To see how PLIP works, I've just setup a couple of
Linux boxes and I can ping between them. I have a way
to go before understanding all the low-level details, but
at least I have a starting point to 'hack on'.

Now, at some point I'd like to replace the second
Linux box with an LPC. The caveat is now the LPC needs
to implement the other side of the PLIP protocol,
and include a TCP/IP stack for dealing with packets.

Yeah yeah, not the most efficient way to deal with
things, this is purely for entertainment at the moment.
I can however think of applications where it would make
sense to waste a little processing power to gain the
advantage of having multiple independent socket
communications between devices. (For example;
communicating between a host processor and another
processor running on a PCI board - networking
without a network interface).

I haven't played with LwIP yet, I have an Olimex board
that I'll use at some point with the CS8900 interface.
But I was wondering if anyone had used SLIP or PLIP
in applications (LPC or not really)?

Of course I will share my results.

Happy Thanksgiving! (to all the Americans out there anyway)
