Read this thread: http://www.elektroda.pl/eboard/viewtopic.php?t=30310
It about PICDEM.net, a PIC web server.

Download TCP/IP Lean II eBook (TCP IP Lean_Ed2.part1.rar to TCP IP Lean_Ed2.part5.rar) uploaded by liuerwu: http://www.elektroda.pl/eboard/viewtopic.php?t=43694
In chapter 12 you will find a description of PICDEM.net
Also download tcp_ip_lean_2nd_ed.zip uploaded by cdcll, it's the CD for TCP/IP Lean II.

still very confused. i'm new to all this so pls bear with my silly questions. i've got a tcp/ip stack already from microchip and i don't know if i require all the bits in it. what bits exactly from the stack do i need to connect my PIC to a network that already exists?

Hi Bereton,

You should be awarded for your question : what bits exactly from the stack

Can you be more specific ? Which bits you're talking about ?

Do you have a full overview of what TCP/IP stack means and how things are going on Microchip's application ?

I know you have something in mind when you ask about bits, but can you elaborate a little bit ?

Regards,
Silvio

I think I can attempt to further explain your question Bereton. You want to transmit and recieve data from your PIC directly to the internet with out a PC yes. Based on the capabilities of a PIC the best you can do is simple I/O operations and signal aquisition such as A/D. If you go through the TCP/IP stack specification, you will discover that you can setup up http service, UDP or SMTP for email,etc. However for your application and considering the capabilities of a PIC I might suggest investigating the UDP protocol because it seems to be the simplest to implement and HTTP if you wish to interface to a web page. Once sorted simply investigate how you tunnel TCP/IP via ethernet which the C libraries supplied by microchip will do for you. At the end of the day, critical investigation of how the TCP/IP stack is arranged might be adivisable. Without this knowledge the sea of information available already will blow your mind away.

you can have a look at mi site and find my proyect "pic16f877 and rtl8019as ISA CARD" with source code in C
I hope it will help you.

See www.orlin.com for the OT731 Kit - a PIC16F877 connected directly to the Internet via a On-board modem.

Available to buy online.

As I found in ME's message, I tried to download the TCP/IP Lean ebook to download, but I do not found the topic may be because of it is moved due to long time !

Anyway, any idea to get this TCP/IP Lean ebook from one place ?
