Is sensor fusion accelerometer and gyro calibration data constant over time
Is MetaMotion accelerometer and gyro calibration data (for sensor fusion) constant over time. That is to say: if I read high-accuracy calibration data for the accelerometer and gyro, will those values always be the same for the same metamotion device? Given that they aren't affected by environment I would think yes, but want to make sure.
Essentially what I want to do is calibrate the devices myself, and have the calibration data in the database. I realise magnetometer won't be constant, however I'm using IMU_PLUS
Comments
As far as I am aware, they are.
Depending on your use case, it is migjt be better to use the macro system to program the calibration data onto the boards themselves.
Thanks. I saw that in the documentation, but am unsure of the exact process. Is there a test case for that in the c++ repo?
There are general macro test cases but none specifically for this example.
