Tcpip

[Darrenmac]

I am looking at starting a project that is basicly a digital/analouge I/O board that is accesable via the internet (or WLAN). The pic side as far as I/O controls would be easy but how do I connect it to the internet? Is there any modules available (similar to those 433MHz Tx & Rx modules) that allow me to send and receive serial data and convert it into TCPIP?

Lantronix xPort is about $50 US. They have virtual comm port software which will let you send & receive with the xPort module using serial methods.

I've been playing around with the Rabbit RCM3710 and the development kit HERE (http://www.imaginetools.com/products/EthernetStarterKit.shtml). It's programmable in C, but pretty easy to catch on to.

Thanks Rhino, that is the sort of thing that I am looking for (much better to lern as well than to plug in a box). Have you had any problems or found anything that I should be aware of before buying one of these kits. Once this has been mastered what do you need to make a working web server(other than programming time).

Can this be done on a pic?

I've just played around with it in my free time.... which isn't very often. I'd like to get back into it. There is quite a bit of source code available to demonstrate how to utilize the webserver, i/o, and email capabilities of the module. I figured if I'd use a pic to gather info from sensors, then send the data over the usart to the rabbit to store and show on the webserver.

Just found a book on Amazon called TCP/IP Lean. It teaches tcp/ip for embedded systems like pic's. Has anyone found any thing like this that is a free download?
