Step count is non-zero even though object is stationary (LIS2DS12)

Hello ST,I am using LIS2DS12 sensor for step detection application. I read the step count register every 1 minute and reset the count value. I observe that even if the object is stationary, the step count register has a non-zero value (The value vari...

Can we use ISM303DAC for detecting vehicle's presence by sensing deflection in earth's magnetic field when vehicle (Ferromagnetic material) enter/depart parking area.

Hello Team ST,Greetings !We are looking for the presence detector sensor for our smart parking project. In this we expect magnetometer sensor to detect deflection in magnetic field and it will give interrupt whenever there is change. Rest of the time...

LSM6DSxx Gyro "Ringing"

I'm trying to use several different IMUs in the LSM6DS family (LSM6DSOX and LSM6DSO32). Both of them are exhibiting "ringing" on the three gyro axes when exposed to shock (knocking the PCB against a table). It almost looks like there's no anti-aliasi...

the sensory library does not work at all.

Hello, I'm working on a project involving voice recognition. So, I used the stm32 sensory library to complete this project and the MP23DB02MM digital MEMS PDM microphone. However, I only found one example that used STM32H747I-DISCO, so I ported it to...

Read lsm6dso32 data via libiio

We are trying to use lsm6dso32 accelerometer/gyroscope connected to a custom hardware (non-st) via i2c. What we want to achieve is reading measured values continuously, ideally via libiio (buffered).We are building a custom linux (kernel version 5.4)...

in LSM6DS3TR The accelerometer is activated from power-down by ODR_XL[3:0] in CTRL1_XL (10h) the gyroscope is activated from power-down by ODR_G[3:0] in CTRL2_G (11h). For combo-mode what we have to do?
