Is LSM6DSL zephyr driver compatible with LSM6DSR ?

Hi, I am trying to create test the STEVAL-MKI194V1 for a test vehicle, which has LSM6DSR. However, I do not get an initialization response from it using the Zephyr device tree. So, I did a test (without the DSL driver) with the spi shell which gives ...

Resolved! LIS2DH12 bypass capacitor

Hi, I'm putting down a LIS2DH12 accelerometer on a new PCB. The datasheet calls for an aluminum capacitor on VDD, but the eval board (STEVAL-MKI151V1) shows a small capacitor that looks like a ceramic. I don't know for sure because I can't find the B...

How to Change Sampling Frequency for ST BLE Sensor App

Hello STM32 Community,I’m currently working with the STEVAL-PROTEUS1 evaluation board, which integrates an STM32WB5MMG microcontroller and an IIS2DLPC MEMS accelerometer. I’m using the board together with the ST BLE Sensor mobile app, and it works gr...

Practical water resistance of LPS33HW LPS27HHW or LPS28DFW

Although these devices are technically "water resistant", they are sometimes described as "water proof" (even in STM materials), and the data sheet permeability of the gel is quite low. Clearly these devices can survive immersion for at least several...
