As seen in the video below, when the compass unit is set at an angle, the heading output varies significantly-as much as 100 degrees according to the project write-up.Using the MPU9250 to get Real-time Motion Data Code and explanation for getting directional and motion data from the raw sensor outputs. ![]()
