Arduino to Arduino I2C communication

1

I am trying to setup I2C communication between two arduino Nano’s but cant seem to establish communication.

I think the problem might be that XOD nodes assume that the Arduino is always considered the master. But I need to be able to configure 1 arduino as a slave and 1 arduino as a master.

Is there any libraries that can assist me?

Or perhaps I am doing something wrong.

Any assistance would be appreciated.

I2C slave mode does not exist in XOD yet (due to lack of interrupt control). Here is an example of communicating between boards using UART: Controlling LEDs via UART — Exchanging Text-based Data Between Two Boards — XOD
