Description

The acceleration readings of the MPU9x50 currently looks pretty random (using a breakout board). I recall that students were able to track nearby tram traffic with the acceleration data, but now there is a +/- 2g noise on the data.

Steps to reproduce the issue

Flash the test app, connect an MPU9x50 breakout, observe the reported readings.

Expected results

The reported acceleration vector is about 1g in length and points roughly in the same direction while the sensor is not moving.

Actual results

The acceleration vector is jumping like crazy both in direction and length.
