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: **broken link removed**
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?
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.
