Have anyone used Davicom DM9000A with AVR?
Im interested in result of that project.
Im going to use this ethernet IC in 8 bit mode with AT90CAN128.
I have done DM9000A simple driver. DM9000A register set is more simple than RTL8019AS. Fast and easy to program and small footprint (tqfp48). I recommend it to new projects.
Here's the simple driver (not final, but works):
PC -> can128 @8MHz Ping result is cc. 500us (non-interrupted version on can128).
