I am trying to find out what example code I can use with the Xadow IMU 6DOF. You built your library for this module on top of the i2cdevlib code at github. Other examples using this library require the use of an interrupt. Specifically, it is required that the MPU’s INT pin is connected to the ATmega32U4’s Pin 19 (which is Digital Pin 2/SDA on an Arduino Leonardo).
It is very confusing to figure out whether this is possible on the Xadow.
I looked at the eagle files of the the Xadow main board and the Xadow IMU. To me, it looks like on the Xadow, the Pin 19 of the ATmega is connected to PD1/SDA/D2 and line 10 on the FPC interface, and then SDA on the MPU6050.
The INT of the MPU, however, seems not connected to the bus. Is that correct? If yes, does this mean that there is no way to use interrupts with the combination of Xadow main board and Xadow IMU?
