MEMS ACCELEROMETER LSM6DSV16X Remove Gravity

[FilipeLourenço]

I am using steval mkbox-pro with FP-SNS-DATALOG2 to get acceleration from the subway train.

How can i remove the gravity effect in measurements from the LSM6DSV16X accelerometer?

Thanks @Andrea VITALI.

I will try to do the implementation.

Hello @Andrea VITALI 

After reading all the design tips that you recommended, i saw that DT0060 using gyro was the best since i am going to do acquisition on a moving subway train, so i have linear acceleration too.

But in DT0060 i have to get the initial orientation, how can i do that? Using DT0058 (acc+mag) just for the first value of acquisition(when i know that the sensors are not moving)? Does DT0058 also works without using low power accelerometers?

Another question, you talked about doing the magnetometer calibration...I have to calibrate all the sensors that i want to use? Or it's already calibrated? I am using LSM6DSV16X and LIS2MDL.

Thanks again for the help!
