I am an engineering student doing a project on controlling a lab throgh a remote user to LPC2378 microcontroller placed in lab. For the remote user to enter the details and recieve information i have designed a website in asp.net using Visual Basic language. Now i want to link the site to the LPC2378 through ethernet. Please could any one help me with this.
So the website is, in fact, entirely irrelevant to the microcontroller (LPC2378).
You need to devise some protocol for transporting the required commands from the server to the microcontroller, and the microcontroller's responses back to the server.
You could do this using "raw" sockets, or you could use one of the higher-level protocols such as Telnet, FTP, HTTP, etc, etc, etc,...
This is a fundamental part of the design of your project!
For a tutorial on sockets, see: www.frostbytes.com/.../sockets.html (BSD), Or: www.frostbytes.com/.../winsock.html (Windows)
