Serial over Ethernet - Webserver

[mackrackit]

I have used the wifi version of that part some and it is almost that easy.

I did not use it as a web server because it will only do port 80 and the systems I work with have port 80 used by Apache.

It can be used to send and receive serial data via Ethernet. Jeremy and I tested this by sending "text" messages to each others terminal.

I have used it mostly as a remote data logger. Information is collected by a PIC®, sent to the module with the appropriate commands to and/or FTP the data to a server and send out an email.

This is no longer running, it was just a test. The web page lived on the server and would pull the temperature data from the file the iChip FTPed. That was how I got around the port 80 problem. The PIC® code is also on the web page.

Dave, looks fairly simple

I might order one of these to try at some point. DT wrote the routines to display each channel of the thermostat via serial, and I was hoping that this device would do the same in HTML (I read that it can store web pages).

It's not critical yet, I want to get some headway with the PCB design for the thermostat project first

Yes it will serve web pages. This is from memory so I may be off a bit...

The web page memory is something around 128kb. You create the HTML with whatever you use for that, then the iChip has software you can download to convert you HTML into an image file that lives on the iChip. You can have "parameters" in the HTML that become dynamic via serial input.

Like I said, from memory. Only played with that part a little.

And the Manufacturers web site carries a mass of information and a very good tech support forum.

Thanks Lester,

This gives me more scope, and price wise £26 is not a huge outlay.

Lester, looking at your site and Tibo's there seems a lot to choose from.

Any idea of price and availability of http://www.crownhill.co.uk/tibbo/EM202.php - EM202 unit and is this a suitable unit for converting the TX / RX TTL lines from a PIC to Ethernet ?

The EM202 is an older part, the above links show suitable replacements.
