MEMS (sensors)

Resolved! What is MEMS sensor hardware self test principle?

 Dear all:From this diagram we can see that, gyro test is calculate whether the difference between the two data values is within the range.I want to know Write 04h to CTRL5_C (14h) Enable, What does the hardware do? What does it mean if the data ...

Resolved! Which techniques are used in IIS3DWB ST's libraries (Motion_SP) to determine velocity(mm/s) from acceleration measurements(g) ? Theoretical foundation from functions "MotionSP_SwSpeedRmsFilter" and "MotionSP_TD_SpeedEvalFromCircBuff".

There is too much uncertainty ? Would be possible to use this measurements to evaluate mechanical vibration according to ISO10816-3 ?

Resolved! IIS2DH aliasing at low ODR settings

AFAIK the IIS2DH has no anlog anti aliasing filter. So will aliasing occure if I use low ODR settings and the input signal is frequency is higher than ODR/2? Because in our test we are getting quiten often spikes in the signal output signal. And if t...

Resolved! hello everyone! I am using LSM6DSO in a small project for tilt control and interrupt generation.

I use the register settings from the documentation:1. Write 80h to FUNC_CFG_ACCESS // Enable access to embedded functions registers2. Write 10h to EMB_FUNC_EN_A // Enable tilt detection3. Write 10h to EMB_FUNC_INT1 // Tilt interrupt driven to INT1 pi...

Resolved! Good night. I have a LIS2DH12TR over an ATSAML21E17B. I´m reading the values of axis (x,y,x) transforming the values to degres (from -90º to 90º) but I need degrees from 0 to 360. I have tested a lot of formulas but nothing. Any idea? Ty.

This is the configuration of accelerometer:// Enable Block Data Update lis2dh12_block_data_update_set(&dev_ctx, PROPERTY_DISABLE); // Set Output Data Rate lis2dh12_data_rate_set(&dev_ctx, LIS2DH12_ODR_100Hz); // Set full scale lis2dh12_full_scale_set...
