Hi, We are experiencing "glitches" on the ACcelerometer values once in a while. we are using 52Hz rate. expected values are 1000mg +-100mg on the Z Axis. Once in a while we see several samples going down significantly.

Hi,We have been using LSM6DSOX in our Pool Alarm Unit.The Device is floating horizontaly in the pool and valid Z axis Acceleration is around 1000mg.We are currently facing a problem that is caused by seldom "glitches" on the Accelerometer values.Devi...

LSM6DSO ACC and GYR setting

Hi,I am using LSM6DSO to measure acceleration and angular velocity. To save the power of device, I want to use accelerator in most case. Some conditions, the gyroscope will need to open. I used the function 'lsm6dso_fifo_xl_batch_set', 'lsm6dso_fifo_...

When can I write to INT1_CFG in the LIS3DH?

I am using the LIS3DH MEMS motion sensor. To generate interrupts when motion exceeds a threshold, I need to set certain flags in the INT1_CFG register (address 0x30). The manual says: Write operation at this address is possible only after system boot...
