Resolved! I'm looking for a mems or IMU sensor solution can be measured X. Y, Z axis tilt within 0.05 degree repeatability.

Resolved! Lsm9ds1 datasheet says, gyro sensitivity is 8.75 mdps/lsb for full scale +-245 dps. To convert raw data to mdps should we use 245/32768 or 8.75/1000.0 ?

regarding the ISM330DLC I downloaded the datasheet. I have few questions. Where can I see the bandwidth for the gyroscope and the accelerometer. That sensor is programmable. How can I program it? Do you have a video or training for tat sensors?

Resolved! I am using Sensortile.Box which has a analog microphone. I thought whether DFSDM filter can be used. Kindly confrm STM32L4R9ZI supports internal ADC to use DFSDM .

Resolved! X-CUBE-AI

hi, am doing a keyword spotting in SensorTile_Box. I have done TFlite model and analyzed in MX tool, generated C code. Now, I want to know where the execution takes place. I want to use LED when it recognizes the voice. But, I didn't know where to wr...

Resolved! MTBF/FIT data of LIS3DHTR (3-axis accelerometer)

Hi,We are working on product reliability calculation and need LIS3DHTR's MTBF and FIT data for the same.Can you please share it?Thanks,Hitesh

Resolved! LSM6DSL anti-aliasing filters do not appear to be implemented despite setting appropriate registers according to the datasheet.

I am using the LSM6DSL for a high frequency vibration measurement involving the accelerometer sensor only (gyroscope is turned off). Output data rates are variable between 400-3.3kHz. A recent frequency sweep experiment (0-6kHz applied on external sp...

Temperature drift LSM303AGR

we made a compas with the LSM303AGR. it is with endusers already. the problem we encounter is that the RAW sensor values drift with temperature change. we tested fom -8C Celcius to +29C Celsius. the RAW values drift substantially. we have set the Com...

Resolved! How long does it take to turn on the heater in MEMS HTS221?

Resolved! Issues in Configuration of the 'ST acoustic libraries' for audio sampling from default value 16k to 96k in the X-CUBE-MEMSMIC1 example

I have been going through the X-CUBE-MEMSMIC examples on the STWINKt development board. There are two examples 'AMicArray_Acoustic_SL' and 'AMicArray_Microphones_Streaming' are given. AMicArray_Acoustic_SL - is sampling audio at 16k and providing the...
