Adding TCP/IP Ethernet to PIC - how?

The Mouser issue is really with the USA's Homeland Security Department created after 9/11 which is staffed with bureaucrats who are all trying overly hard to be sure they won't be the one to miss the next terrorist. It's more than a bit ironic that they want to prevent the export of a device that was imported to begin with.

I'm not trying to make you the bad guy, merely trying to point out the reality. I used to run an international operation (US subsidiary of a European company) so I have different point of view. The manufacturers, besides not wanting to get bogged down in minutia, probably see a potential liability if they provide too much help and detail especially for another company's product. Like Homeland Security they err on the side of caution although it's those other terrorists (trial lawyers) who worry them.

I realize that there's a fine line on these (and other) forums between a beginner asking for help and asking that someone do all the work for them but, maybe you should have responded earlier that you had read the docs (citing them with some specifics) for a particular device but still needed help getting started. That may have elicited some help from myself, mackrackit, Charles Linquis, ioannis or ????. Maybe I didn't read your earlier posts as carefully as I should but I don't recall getting the feeling that you were a complete beginner. Plus, the ConnectOne and WIZNet docs do

at least show "what codes" are needed to initialise the ethernet adapter, and then how/what is expected to be sent to the adapter to get it to do "whatever"....

After all, that's where mackrackit got the info he used to get his device working. And it's why I recommend those specific devices - because I know they have provided all the needed detail. I think you either did not look hard enough or did not understand the manuals.

Section 4.1 of the WIZ110SR User Manual (Version 2) available as a PDF on their website shows step-by-step how to configure the device over the serial link. You can experiment from a PC and then connect to your PIC serial port and send the serial commands that way. If you are asking how to establish a UDP or TCP link or do SNTP, SMTP, etc. that is not part of their instructions but you can read the Internet RFCs - most of the protocols use plain text commands or you can look at Tibbo's examples which, while written for their device in their Basic dialect are easily converted for use elsewhere.

ConnectOne has a Programmer's Manual that details all of their ATi+ serial commands for configuring and communicating via the serial link. IIRC you need the manual for the specific chip used in the device you use. The docs are at...http://www.connectone.com/support.asp?did=42
