How to measure gyro sensitivity with extremely high accuracy?
Hi,My company uses the ASM330LHH for dead-reckoning applications and we are trying to improve the performace of the gyro with our own calibration of rotation sensitivity. After calibration, we want the gyro sensitivity accuracy to be 0.1 % or better ...
LSM6DSV half precision error at ~180 degrees
Hi,We're using the lsm6dsv's SFLP algorithm to calculate IMU rotation. Recently however we noticed that the resulting rotation has big gaps at around the 180degree mark. We believe this is because of the half float precision, specifically because the...
Unable to calibrate LPS22DF
I am using a python script to update the One Point Calibaration register 1Ah, 1Bh. I put values in but the resultant reading of the normal pressure registers in 28h, 29h, 2Ah are way off. Does anyone have a script that might show exactly how it is do...
Resolved! IIS3DWB: Issues with RMS Accuracy Using IIS3DWB on Z-Axis at Higher Frequencies
Hi, I’m working with the IIS3DWB accelerometer to acquire single-axis data (Z-axis) using the following setup:Full Scale: ±16gSPI Mode 3 at 10 MHzTarget ODR: 26,667 HzI have attempted different methods to read the Z-axis data. First, I tried reading ...

Hello awsome peaple of the ST fourms,I've been writing a program on the MB1551-U585AI1-D01 STM32U5 dev board, after getting DMA working and writing some AzureRTOS aware platform functions for the MEMS sensors on the board I have been very successful ...
Gravity problems on IIS3DWB
Hello community, I am an electronics engineer at the CNRS in Montpellier (France). I am currently working with the IIS3DWB vibration sensor When I use the LFP2 low-pass filter, the action of gravity is added to the measurements. I use the following d...
Resolved! LSM6DSV16X Sensor Fusion (SFLP): Does It Use Filtered or Raw Data?
Hello all,I am working with the LSM6DSV16X and trying to determine whether the Sensor Fusion Low Power (SFLP) algorithm processes raw or filtered accelerometer and gyroscope data. Specifically, can I adjust filtering settings (e.g., LPF2 bandwidth) b...
Resolved! X-CUBE-MEMSMIC1 : libhs_datalog.so for Raspberry Pi 5 or source code available?
@SimonePradolini Hi Simone,Can I get a 64 Bit version of libhs_datalog.so for Raspberry Pi 5 of the X-CUBE-MEMSMIC1 expansion software package please?Or the source code to compile it?Unfortunately DATALOG_V1.5.1 just provides a 32 Bit version libhs_d...
LPS25HBTR pressure reading decreasing over time
I have bought a MKI-165V1 to test LPS25HBTR,but I find that the pressure value is decreasing for a long time ,from 1014.117 to 1002.970 in an hour.It is not stable,the next is my initial code,what is the reason for ituint8_t data = 0x90;HAL_I2C_Mem_W...
