Hey everyone! I'm working on a university project using BNO055 in order to come up with a filter algorithm for MEMS IMUs. I recorded some data while the chip lay exactly horizontal on the ground as to examine the remaining offsets after the calibration routine and found small offsets (~ 0.2 m/s^2). As I'm trying to find the "true" offset, I would like to get the raw, uncalibrated accelerations out of my data. I saved the calibration profile for each of my experiments, but I'm not sure as how to interpret the numbers given in the calibration profile. For example, I have "calibrationData.accel_offset_x = -21", what does the -21 mean? Is it maybe bits in relation to the sensitivity given in the data sheet? Also, I was wondering if you could give my any more information about how the calibration algorithm in the firmware works exactly? And, last but not least: Can you tell me how to interpret the "radius" parameter in the calibration profile? Thanks in advance! Louisa
