Is it advisable to connect the Arduino 9-Axes Motion Shield with Raspberry Pi because the official guide says that the only way to power that shield is by stacking it on top of an Arduino board.
For a moment, let's say that the shied does get powered on through RPi (using its 5V and GND pins). How do we read the data serially (I2C) through the RPi as there are no libraries installed for the shield like we have in the Arduino IDE which gives out well defined data for the three axes.
