Chip select operation on MEMS sensor ISM330DLC and others.

Hello,I'm just looking at the CS pin operation of ISM330DLC and other ST mems sensors. It seems the when (CS=1) its in I2C mode. When (CS=0) its in SPI mode.Where I'm using multiple devices on an SPI channel with a sepearate CS for each device, what ...

Hi, we are working with LSM6DSL sensor, we need some info regarding the sensor. In the configuration sequence of sensor is it possible to change ODR with out turning OFF sensor an turning it ON back ?

LSM6DSO CS pin config for I2C mode

Hi - I intend to use the LSM6DSO chip in I2C mode. Can you let me know if the CS pin can directly be pulled to VDD or needs resistor to VDD? IF so what may be recommended value/

Hi, We are working with LPS25H connected in I2C. Working fine. But getting 6.5mBar Pressure deviation comparing with our standard Barometric pressure meter. Please kindly suggest what to do??

LIS3DH Temperature calibration and drift over reset cycles

Understanding that the temperature sensor on the LIS3DH provides a relative value rather than absolute... Is it possible to calibrate this value for an individual sensor against a known measured temperature and then use the relative changing value to...

LSM303DLHC heading calculation

Hello everyone. I have been struggling with creating the tilt compensation compass. I have prepared the code which is based on demo firmware but I don't receive reliable output. I mean, when I rotate the development board, the heading value doesn't l...

Mems Library IKS01A3 e-compass

Hello eveyone, I used LSM6DS3 mems that I would like to get quaternion data, without MAGNETIC. Can I use MotionEC_Run function and without MAGNETIC?And then, I try to run MotionEC_Run(&data_in, &data_out) function under the STM32CubeExpansion_MEMS1_...

LSM9DS1 Library

Who knows where can get LSM9DS1 Library for STM32?I ever find the X-CUBE-MEMS Library, but I didn't find LSM9DS1 library. And then, If it can use, but its magnetometer different to X-NUCLEO-IKS01A3of LIS2MDL. How should modify by its library?

Reading HALL Sensors values from HALL interface

Hi dear members, I am trying to understand complete how to drive bldc motor.And I would like to use hall interface in stm32.how can I manage to read commutation using hall sensors which registers I couldn't find it in reference manuel.And also how ca...
