What controller chip?

-------------------------------

I think it's ENC28J60 but i have to check this.

I wrote ENC28J60 test routines for SPI and UDP, released under the GPL:

After that I re-wrote it in PIC asm, but that does not help you with an Atmel. But you could use the C code to see how to drive that chip, or even compile it with the right I/O. No TCP, I do not know if there is a free TCP stack for that micro of yours.

Uff, thank you i will take a look at it.

Tell what do you think is it possible to connect multiple atmel controllers on one web server PC ? This would solve a bunch of problems for me.

Do you know if there is some tcp stack that i can buy ( for atmel ) ?

I really do not know, have zero experience with Atmel.

loop_the_loop: The world changed, I have some Raspberry Pis now, running Linux. If you need networking of any kind, that is likely the way to go as far as price / performance / ease of programming goes. (Full free GPL OS, and excellent networking for LESS than I can make a PIC board with ethernet, connectors, SDcard interface, and HDMI HD video out.. 35 $, enclosures available cheap too.

No, but goto loop_the_loop

I usually take the simple route and drop an XPort onto the board. It's not perfect but it is fairly bulletproof.

### lwIP is a lightweight implementation of the TCP/IP protocol stack. The focus of the lwIP TCP/IP implementation is to reduce RAM usage, thus making lwIP suitable for use in embedded systems with very limited resources.

Features

• TCP/IP suite description
• 32-bit AVR\xc2\xae UC3 lwIP port source file architecture
• Web, TFTP, SMTP servers:

- Network configuration

- DHCP protocol
