IIS3DWB offset calibration is missing

[Pavel_Levkoev]

Hello All,

is it normal that the data in the offset calibration registers disappears after a power restart?

Hi @Pavel_Levkoev ,

Welcome to ST Community!

Do you mean registers: 73h, 74h, 75h?

[Pavel_Levkoev]

Yes exactly,  and register  CTRL6_C (15h) with USR_OFF_W bit.

at the moment, I have to save calibration values to non-volatile memory and set them every initialization. It seems to me that something is wrong here, because logically such calibration is mainly used for correction and displacement after soldering/assembly. I.e. ideally only once.
