Hi,
You may want to have a look at the protocol-on-chip solution by Wizne
(see http://www.iinchip.com). The IIM7010A is a piggy-back modul
containing the W3100 processor with TCP/IP stack, and the physical 10/10
Ethernet interface plus RJ45 connector. It can be connected to the hos
AVR via TWI. This approach saves you a lot of headache, code space
development time and licensing questions.
Plus the achievable performance is far better compared to a software-onl
solution.
I used this module on our "AVR Playground" Experimental board (http:/
www.avrcard.com).
Regards,
Hans

i mean A/D not A/C - a language mistake, A/C is in polish
if you have some interesting experiences or materials mail me:
gxo at wp dot pl

Yes i think i have a lot stuff and code laying arround for that project

same here, i just didn't connect the sram,casued by error in chip select...
fixed now...
bot the project is cancled, due to another HC12 uC(only need transformer and
RJ45 externaly) and FPGA
http://rapzak.mine.nu
(will do some debug on it today)

you mean by this?
checking state of <=100 input datalines, and

I think so:)
i think i will be able to mailyou some different things if you prefer :)

Hello
Anyone has used a TCP/IP on AVR??
I'm planning to build a system consisting of ATMega128 + external SRAM +
RTL 8019. I'm thinking of use "uIP TCP/IP Stack".
It will be sending about 200-500 bytes of data to the server on TCP,
doing 8 A/C conversion, checking state of <=100 input datalines, and
setting ~30 datalines each second.
My question is:
What will be performance of that system? Will AVR runing at ~15Mhz be
able to do all this tasks?
Any help will be appreciated
