Do you know the following characteristics (typical values) on the gyroscope and accelerometer of LMS6DSM : - Scale factor - Axis misalignment - Bias stability ?

Hi @NPoth.1 ,
yes, I can share you some characterization / bench measure data -especially on the last two parameters-, since they are not in the datasheet:
- Scale factor: the LSM6DSM is digital, so the exact conversion factor from voltage to digits depends on the internal ADC. However, the sensitivity -that depends on the selected Full Scale-, is defined in the datasheet, p.23: for the accelerometer, (milli)g stands for 9,81m/s^2 (/1000), the Earth gravity acceleration, while dps stands for degree per second. For example, in the FS=2g case the accelerometer sensitivity is 0.061 mg/LSB, meaning that a variation of 1 bit in the data output refers to an increase of 0.061 milli-g sensed.
- Axis misalignment (i.e. "cross axis" parameter, or non orthogonality):
- For the accelerometer (X to Y, X to Z, Y to Z):
- For the gyroscope (Pitch to Roll, Pitch to Yaw, Roll to Yaw):
- Bias stability:
- For the accelerometer:
- For the gyroscope:
