Only 1 I2C port?

Posted by Chinab Chugh on June 6, 2011 at 9:04pm

Hi All!

I am using the ArduPilot Mega kit. I wanted to connect a Gumstix to the ATMega 1280 chip via the I2C port. But I just figured out that the magnetometer also uses the I2C only (it is connected via the IMU shield).

So, is there any other I2C port which I can use?

Or any suggestion on how to make the connection.

Thanks

Use the DIY Drones I2C hub/splitter.

I2C peripherals are addressable so you can daisy chain up to 127 depending on if you are using 7 or 10 bit addressing on a single connection.
