Ethernet/LAN interface

Archiver

Hi,

I found this little interface.

There is basic stamp code in the application notes section.

Has anyone used this, and does anyone know a similar
module with a serial interface (preferable I2C), because this one uses 16
I/O pins.

Hi,
What I did was use two shift registers (one serial in-paralell out, one paralel
in-serial out) for the data bus (D0..D7) and one more (serial in-paralell out)
for the control and address bus (A0..A3, /RD, /WR, /AEN). By this form I only
used 9 pins (3 for each register).
A better way is to use an I2C bus expander, like the PCF8575C (16 I/O I2C bus
expander):

Hope this would help
