What I was referring to is that writing to an external address is simpler and faster than communicating by I2C or SPI. And this board can do this.Ok so what are you trying to communicate with?
The Wiznet chip is a good example, you could place parallel ADs, alphanumeric LCDs, memory...
I'm not trying to communicate, I don't even own a Mega board. But that it would be a nice thing to have, it would...
So this will work with anything that uses a compatible parallel interface. There's nothing stopping you from doing it, go try it out. I think all you need to do is read from and write to pointers beyond the AVRs internal memory and the AVR will automatically use the external interface when it needs to. Try it out and disassemble the compiled C code to see if the assembly is going to do what you expect.
