I am using RTIMUlib to obtain values from a 9 axis IMU (MPU-9150). I am getting the ‘default’ data to be displayed OK (accel, gyro, Mag & Fusion). However I would like the accelerometer values to be displayed minus the gravity element. I have read on this forum that RTIMUlib should be able to provide that data but I cannot figure out how to get it. Please can anybody help?
