Hello!

What is the easiest way to connect an ATmega Controller to the Carambola?
I need a lot of I/O´s and it must work "outside" of the carambola.

Thank you!

Carambola 2 has SPI and I2C protocols, but both of which are software simulated and can only work in master mode. USB is also a viable option, but neither I, nor anyone else could answer which is the best/easiest way as that is very skill-set and application dependent.

As for examples you could read viewtopic.php?f=13&t=833, viewtopic.php?f=13&t=782, viewtopic.php?f=13&t=832, search for older posts and also on other (especially OpenWRT) forums.

I did I2C - very simple

grab this https://github.com/devthrash/I2C-slave-lib/ and hook up I2C (two wires + 2 pull up resistors)

You can get this solution running very quickly
