Hello,由于是第一次开发mems传感器,在开发ASM330lhh过程发现静止状态下角速度和加速度的偏差较大,没有趋向于0,不是很清楚啥原因,是否配置存在问题,如下是我的配置,以及观测到的数据。

角速度和加速度0-2分别是X,Y,Z轴的数据。

Hello, since this is my first time developing a MEMS sensor, I found that the deviation between the angular velocity and acceleration in the static state is large and does not tend to 0 during the development of the ASM330lhh. I am not sure why, and I wonder if there is a problem with the configuration. Below is my configuration and the observed data.

Angular velocity and acceleration 0-2 are data of X, Y, and Z axes respectively.
