LSM6DSL Accelerometer data deviation

Hi,We are using LSM6DSL for one of our products and in that we have noticed that the Z-axis Accelerometer deviates due to change in temperature for a stable orientation as shown below which is affecting pitch of the product  by -1 to -2 deg.    The I...

FIFO Readout not working properly

Dear ST- Community, we are currently implementing a new function to our existing device with the following function: We want to detect, when the device is tilted. This function is not time critical at all. The most important fact is energy consumptio...

Resolved! LIS2DW12 Unable to communicate through I2C

Hi, I am using the LIS2DW12 on my board communicating over I2C with the nRF52840.  I have not yet been able to communicate with the accelerometer at all, and all attempts to read or write end the same way (see screenshot)I have the CS and SA0 lines b...

Resolved! LIS2HH12 activity/inactivity interrupt behavior

I have configured the activity/inactivity function, but I only get the interrupt raised on inactivity, not on activity. Is this function supposed to be able to alert me to both activity and inactivity? Or is it just inactivity that raises the interru...
