Given that the Madgwick filter implementation is correct, I pass acceleration values measured in Gs, gyro values measured in rps (radians per second) and Magnetometer values measured in uT, while sampling time is. There are only two filter settings that require attention: the gain, and the sample frequency. The volume was main-tained at 400mlbyaseptic addition ofsterile distilled water. I have zero experience with c code and tanslating it and have limited experience with LabView. By inspection, when the first measurement is noise free, the filter ignores the second measurement and vice versa. // the filter is updating at a ~150 Hz rate using the Madgwick scheme and ~200 Hz using the Mahony scheme. The filter is ported from Sebastian Madgwick's paper, "An efficient orientation filter for inertial and inertial/magnetic sensor arrays".
