Hello.. well my on going project to write a TCP/IP stack on a pic is still "on going" and with the holodays here I'm going to get a good chunk of it out of the way. I'm still using slip to connect it to my PC, but recently I'v come to realize how much simpler life would be if I used 10baseT Ethernet. Basicaly because the chips that deal with this have more memory for packets then the pic does ! Any way. I have searched around and found this one http://www.embeddedethernet.com/ But the price of US$80 is a bit off-putting, seeing as I can pick up a complete PCI card from DickSmith (AKA RadioShack) for $10-15 nowdays. I've found others that use old ISA NIC's but I'd rather use something else. So does any one know of other solutions, for embedded mcus that dont cost so much? I know, I know, TCP/IP done a thousand times before on a PIC. but I'm doing it to learn, not to be new. Thanks DaveC

But if you want a board with Ethernet and MCU on board, the cheapest one I know of is to buy a $30 router (wireless even) and take over the Flash. I don't remember where I have seen this discussed, maybe in comp.sys.arm, but this is a really cheap way to get hardware that will talk Ethernet. I bought a four port switch for FREE after rebate, I don't know if that will do the same job as what you need. If I open it up right now, I won't be able to send off this post! 8-O -- Rick "rickman" Collins rick.collins@XYarius.com Ignore the reply address.

Your MCU won't do PCI, so it's not an option. However, you should be able to do ISA with enough I/O lines (about 16-17, IIRC)> I've found others that use old ISA NIC's but I'd > rather use something else.You want cheap and MCU-capable, this is your path. In the $10 range for an NE2000 ISA card. About $2 for the socket from Digikey. If you're adventuresome, you could jump straight to an etched PCB with a surface-mount RTL8019AS NE2000 Ethernet controller. However, life will be much easier if you prototype with the ISA card first - pin connections and drivers would be identical. See this AVR-based ISA-card breadboard project for ideas. It could be adapted to PIC, and it's got free schematics: http://www.picoweb.net> So does any one know of other solutions, for > embedded mcus that dont cost so much?If you consider $80 too high, this probably isn't much better, but it's an option: http://www.edtp.com If you want cheap, use ISA. Cheap and non-ugly, buy a proto board. More budget... use chips, design your own board.

The code for the Samsung SNDS-100 (KEB50100) board is said to run on this. The S3C4510B is a great chip for this sort of work.

you might consider IPu8930 from IPsil http://www.ipsil.com/products/d8930.htm Available from Adilam Electronics in Australia www.adilam.com.au Comments - Ipsil has preliminary data on their IP�8932 which combines a webserver, Ethernet MAC layer, and TCP/IP controller all on a single chip. This allows the one chip with 20 digital or analog inputs to display webpages without the need of a microcontroller. Ipsil has WebHolesT technology which allows holes (simular to server side includes principles) to be filled in with values from the I/O ports. If you do happen to need more complexity, you can add a microcontroller and talk via standard TCP/IP socket calls.

This will sound silly but I am already writing my own so only need 10baseT Ethernet connectivity for the PIC mcu DaveC

If you use http://focus.ti.com/lit/an/slaa137a/slaa137a.pdf as a reference it should not really be such a big deal. Markus

The SMSC91C9x devices are easy to write code for, and the CS8900 is fairly easy, so go with one of these. If you haven't got it a copy of Jeremy Bentham's book "TCP/IP Lean" is a must.
