Lpc2000

Hi all

I have been away for a while but did make a few postings in the past
concerning a project I have been working on with the LPC2106 and 
Freescale MC9S12NE64 as TCP/IP co-processor.

Finally there is something which may be interesting for you to take a
look at.

I have an NE64 running on the DEMO9S12NE64 at the following address
http://212.254.22.36/

The software, including TCP/IP has been developed from scratch (using
OpenTCP as initial reference) and compiled using the GNU compiler (of
course). It is possible to use this as LPC2106 co-processor via SPI 
or simply as SPI/LAN connection with the code on the LPC2106.

The example is explained on the in-build web page in more detail but
after experimenting a little have settled for the following 
solutions:
- I did use TELNET initially but dropped it for HTTP and FTP
parameterising / file loading [strangely neither TELNET not FTP were 
a part of OpenTCP when I looked at it]. For HTTP I use a 16k page as
file system allowing updates via drag and drop to FTP. On the NE64 it
is a good compromise since it is then possible to use the remaining
48k FLASH without paging (and the overhead and complications which
come with it).

The application which is presented also support LAN/RS232 conversion
plus some other things.

At the link there is a web cam and you can send an Email to the demo
and see it receive it (on LCD). I can also control the display over
the Internet using a special application and will have a program
available in the near future allowing anyone to control it from a
control panel.

I would be interested to hear from anyone with similar interests or
comments on the demo.
