Abnormal results from accelerometer and gyro from IMU

Hi

I am a (very) new developer working on the xiao ble and I am just exploring certain functionalities of the xiao ble.

I am using the readFloatAccelX() and other similar functions to get the readings of the x,y and z coordinates from the accelerometer and the gyro while having the device placed stationary.

However instead of getting static values, they keep changing. May I know if there is anything wrong with my way of getting the values? Thanks!
