Anybody using AVR and ethernet interface? Which TCP/IP stack are you using?
yes.
WizNet’s 811MJ module.
The cheap module includes on-board:
Ethernet MAC/PHY/RJ45
IP
TCP
ICMP, UDP, ARP
4 Socket interfaces, each with TX and RX buffers
SPI or parallel interface.
So much easier than a microprocessor-resident IP stack.
In the AVR, I’ve implemented my own C code for
DHCP
DNS
SMTP
SNTP
chron
HTTP server
Dynamic HTML
under the free AVRx RTOS.
