LIS2DH12 HOWTO Convert Register value to mg value

Hi,  I am using the LIS2DH12 to interrupt me on an inertial wake.  I am running in Low Power mode with a scale of 4G.  After verifying that the X axis produced the force that caused the interrupt I read the X_OUT_L and X_OUT_H registers to get the 2'...

LSM6DSV16X: wrong WHO_AM_I read on SPI interface

Hello,I am trying to interface a Nordic MCU to a LSM6DSV16X, but I cannot get the communication to work.I am using 2 dev kits for this test setup, a nRF5340-DK and a STEVAL$MKI227KAA I got from the STEVAL-MKI227KA. VDD/VDD_IO are both 3V, CS/SPC/SDI/...

Lis3dh reading not repeatable/stable

HiWe are developing a project in which we are using LIS3DH to calculate the angle and based on that angle we stop/start an actuator.The sensor is mounted on a PCB which is aligned along x axis i.e. when stationary the acceleration in x axis is 1g * 9...

LSM6DSO analog anti aliasing

Hi,I would like to confirm if setting LSM6DSO ODR to 6.66KHz and LPF2 to ODR/10 (resulting to 666Hz bandwidth), then setting a FIFO decimation factor of 8 (resulting to 833hz FIFO ODR) will work in preventing aliasing for signals above 417Hz? We have...
