Hi, we have been asked to develope a simple Ethernet I/O node; the board should be able to send input status and receive output configuration via Ethernet packets. This would be our first project including Ethernet (we have already designed similar systems based upon RS485 or CAN networks); any suggestions about basic books/faq/documentation? We normally use AVR and Renesas 300H in our designs, but the customer is suggesting MC9S12NE64 from Freescale. Thanks! Capoccetta

What sort of through put do you require? Are you going to be a master or slave? There are lots of options but more specifics are required. If you are wanting to use TCP or UDP then I would suggest the following link as a start. http://www.tcpipguide.com/ Regards, Richard. http://www.FreeRTOS.org

Are you going to be a master or slave?My node should be connected to industrial PC's; I/O's (16/32 bits) should be refreshed every 10/20 ms; I'm almost sure the peripheral will be a slave.>If you are wanting to use TCP or UDP then I would suggest the following link >as a start. >http://www.tcpipguide.com/Very interesting link, thanks!
