    How to get linear acceleration(Gravity compensation) from the BMA423?

    Hello Everyone,

    I am using BMA423 with ESP32 and programming it on the Arduino IDE. I am trying to get the linear acceleration out of it. But i am struggling to find my way, since i am a newbie with the sensor. I would appreciate any help.

    Thanks in Advance

    Hello an336,

    Do you mean performs FOC(Fast Offset Compensation) on BMA423?

    i mean to remove the effect of gravity so i only get the acceleration in case of linear movement of the sensor.

    i cannot find a fast offset compensation in data sheet,but previously I gave it a try with the manual offset compensation, but i wasn't able to do go nowhere

    Hello an336,

    BMA423 outputs raw data without linear acceleration. Linear acceleration requires an algorithm.

    If you use BHI160 or BHI260, the sensor supports the output of linear acceleration.
