IIS2DLPC Threshold Interrupt

Coming from the IIS2DH which had a simple threshold interrupt by axis that worked great. Can we achieve a similar thing with the IIS2DPLC? Specifically I want to do the following:If an axis exceeds a threshold value it will persist an output (INT1 or...

Hello! Can you let me know about the alignment error and bias instability terms of ISM330DLC model MEMS-IMUs? I have obtained the data sheet but I am not able to see these parameters I need. Thank you very much indeed!

We are making a market analysis on MEMS-IMUs in a private company and we would like to make fair comparisons between different IMU sets and we determined a few performance parameters for comparison. ISM330DLC is in our area of interest and we would l...

How can I determine the value of the register ACT_DUR for a given ODR and a given desired return-to-sleep duration for LIS3DH?

In the data sheet, it is written: Sleep-to-wake, return-to-sleep duration 1 LSb = (8*1[LSb]+1)/ODR. How should I interpret that. It seems equation but is it? If one solves with respect to 1LSB, he/she would get: 1LSB = 1/(ODR-8) but it makes no sens...
