Question from Predictive Maintenance Webinar 29th of April: Hello, in order to compute the ISO Velocity RMS, how can you remove the inclination of the MEMS from the raw aceeleration data using the DWB internal filters?

It is possible to enable the internal IIS3DWB high pass filter (HPF), this option then removes the DC component of the acceleration - the earth gravity. In the webinar we mentioned MotionSP middleware (FP-IND-PREDMNT1), which outputs RMS speed directly but this SW needs to run on STM32.
