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! |

With wires |

Hello! sure with wires, but with which protocol? Serial or I2C possible? I need also some example but did´n found right now. |

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 |
