LIS2DW12 Bias issue

Hi MEMS experts,I am using LIS2DW12 to measure the movement with very rough distance.I tested it by measuring the X-axis only, but it seems to be biased to positive direction.I mean, Moving it to the positive direction : it starts having the + accele...

On IIS2MDC, can I read X,Y,Z, and temperature from I2C in 1 sequence or is there something than requires separate reads between axis and temperature data??

I have the IIS2MDC along with LSM6DSL accel / gyro on a board with stm32L451 uC. Accel / gyro work fine. uC reads status byte then if any axis has new data ready it reads all from temp to accel (0x20-0x2d) in 1 ST hal fn call multi byte read: HAL_I...
