Adding TCP/IP Ethernet to PIC - how?

[flotulopex]

Here is a test thingy I have running part of the time. http://mackrackit.com/mac/ichip/ichip.html

Hi mackrackit,

Thanks a lot for this example; sure, it'll help a lot for a start

I'd like to ask a few questions here and hope some of you can give a neophyte-style answers. And please, forgive-me if my questions sound stupid, I just have no clue what the answers are!

1.- Assuming I connect a well-configured ConnectOne NANO LANReach module to a network (office or so), is it going to be "pingable" just like if I ping another PC?

2.- What is different between the possible protocols the module supports? Is it only the way the data is organized in the packet?

3.- Is there a difference if the module is directly connected to a PC or the module is connected to a network (i.e. via a switch)?

4.- What makes a module's address unique? The IP address and the port? Or is it the MAC address?

That's enough for now

Yes - but only if you've written PIC code to respond to a ping.

2.- What is different between the possible protocols the module supports? Is it only the way the data is organized in the packet?

This is is too big a topic to discuss meaningfully here. Try...http://en.wikipedia.org/wiki/Internet_Protocol

3.- Is there a difference if the module is directly connected to a PC or the module is connected to a network (i.e. via a switch)?

No, except you will probably need a cross-over cable for the direct PC connection.

4.- What makes a module's address unique? The IP address and the port? Or is it the MAC address?

The MAC address is usually fixed and unique. the IP address is changeable.

That's enough for now

Good - I'm tapped out. Maybe mackrackit can elaborate on my answers.
