MPU-9150 Sensor results

Using Arduino Programming Questions
#1

Hello Guys,

I am using the library MPU-9150 which is a 9-axis accelerometer/gyroscope/magnetometer. It's working but results are un-readable for me. So I am sure it's about maths problem but can't get any clue about where to start of...

I just would like to get a temperature in °C. Angles in degree. Acceleration in g, and compas in degree.

Link to the library: GitHub - sparkfun/MPU-9150_Breakout: Example code and PCB design files for the MPU-9105, 9DOF.

Here the results:

Thanks for your answer.

Try this
The MPU9150 is just a MPU6050 with a manometer attached the same way you would with a separate chip.

Lets see if this will get you going.

Also try the attached code to get calibration Numbers for the DMP

Hello,

Thanks for your answer. I tested quickly the sketch but I have to adapt it somehow. I will have some time free this week end so I'll let you know :slight_smile:

thanks
