Hi there,
Iam a novice wrt ethernet and iam starting to learn the same by using LPC2378 based Keil MCB2300 board, to control a device(just On/Off functionality).
Please could you tell me if i could achieve this by implementing a ethernet driver and an application on top of it or is it that i would need a TCPip stack.
Also, if TCPip stack isn't needed then, when and for what type of situation one would need to include it.

regards,
CRP

VSCP (http://www.vscp.org) has been working in this direction
http://www.vscp.org/wiki/doku.php/vscp/spec/phy/vscp_over_ethernet But
AFAI know ther has not been any real testsystems yet. It should work though.

Cheers

You certainly don't need a complete TCP/IP stack but it is easier if you use one. The most commonly used interface to the network is the web browser. So, if the device can implement an HTTP server, all manner of control can take place. There are many devices on the market that do this.

This is just one of MANY similar devices that implement a web server to provide control: http://www.sparkfun.com/commerce/product_info.php?products_id=274

The uIP stack is pretty small. It has very limited functionality but it is useful for implementing projects in small uC. I used the stack on an LPC2106 with an external ethernet module http://www.sparkfun.com/commerce/product_info.php?products_id=200 to grab MP3 files from a web server on my workstation and play them. This was a very interesting first project for my prototype board: http://www.sparkfun.com/commerce/product_info.php?products_id=269 and an MP3 chip: http://www.sparkfun.com/commerce/product_info.php?products_id=519

I have also used the uIP stack to make a TCP connection to an HP LaserJet. Once the connection is made, I can send HPGL strings and use the printer as a simple plotter.
