Hi Group, I have a few questions about creating a custom device connected
to the
internet. The device will have two primary functions
1) act as an embedded (dynamic) web server with the ability to download new
html code
remotely
2) act as a conduit to a microcontroller where TCP/IP packets can be sent
and
received with a simple protocol riding on top to control stuff (say switches
and lights
for arguements sake) Interface to microcontroller could be parallel, SPI or
RS232.

The device would act as one or the other and sometimes both. At this point
there
is no particular requirement for amount of html code, speed, cost, security
etc.
I have a Coldfire development kit and have the option of writing the code
from
scratch based on PD tcp/ip routines but I don't want to spent months
creating
the ability to download dynamic web pages remotely.
I have also looked at some devices like the Digi connect ME or XPort
devices.
It would appear that they would make a good stand alone web server but it is
not clear if they are restrictive in terms of sending raw tcp/ip packets. I
also
don't know if I can download web pages remotely to these devices.
I can provide more details if this description is too generic but I also
don't want
to make this post too lengthy. Basically I am looking for any advice
concerning
off-the-shelf modules vs. writing the code from scratch and pros and cons of
each.
Thanks,
Max
