Hi
I want to use multiple 9 DOF units ( http://www.sparkfun.com/products/10736) together for motion detection . They use i2c to communicate with the sensors on board and the default firmware outputs this data on the serial line. I was wondering it would be possible to have an Arduino as an i2c master that would communicate with the atmega on the IMU boards. So I suppose it could be described as 1 master (Arduino) with multiple slaves (the IMU board) that in turn have multiple slaves (the sensors).
These links to arduino multiple mastrer solutions have been great but those “masters” don’t have slaves.

If it isn’t possible, has anyone a solution that would allow several i2c sensors with the same address to be used together.
Cheers
