Hello, I've built a quadrotor and have connected an MPU6050 accel/gyro to an Arduino Uno, successfully reading any gyro and accel outputs. I'm trying to keep it as simple as possible, so I'm not concerned with DMP at the moment and am only trying to read raw values, I'll implement my own conversions and filters later. The challenge I've been facing now is to feed a LSM303 tilt compass (https://www.sparkfun.com/products/retired/10703) through the MPU6050 ASDA and ASCL. I'm only trying to read the LSM303 magnetometer readings. The current wiring is as follows: LSM303: ----------- MPU6050: SCL <-------------> ASCL SDA <-------------> ASDA GND <-------------> GND with both voltages connected to the Arduino's 3.3v output. The main problems are: 1) How to setup the registries on the MPU6050 for a slave device. 2) How to read the aux ports from the MPU6050 and print them on the arduino serial monitor. I've attached the basic code, you'll notice I'm trying to keep it as simple as possible and for the time being am not using jrowberg's librairies to best understand the process. Any help would be greatly appreciated. Sensor_9DOF.txt
