My LIS3DH seems broken, and the self test results are weird

Hi, I'm using the LIS3DH to detect body movement, but I'm suspecting that the accelerometer is defective as the samples do not seem reasonable (for example, when testing a single axis and turning it all around, it won't go from 1 to -1 g).I wrote a p...

LPS33W vs LPS33HW, and looking for caps

Hi,My company is starting to develop an environmental sensor and we've found the LPS33W sensor to be a nice choice. I have 3 questions surrounding this sensor.I've just found the LPS33HW, that seems to be the same sensor but launched a couple of year...

SPAD Initialization error?

Posted on January 23, 2017 at 18:28I implemented the VL53L0X API in my embedded project. while the call to DataInit works fine (or, at least returns a status OK), I am getting a VL53L0X_ERROR_REF_SPAD_INIT from StaticInit.Any ideas what this means? ...

Resolved! Motion processing feature on MEMS Hardware

@Eleon BORLINI​ Greetings of the Day Currently I am using LSM6DSM as my IMU. Now in this sensor I need to write my own function to obtain the quaternions and then based on that obtain the roll, pitch and yaw of the system. The question that I have is...

Resolved! LSM6DSL filtering chain for static gravity measurement

Hi,I want to measure a static object and approximate tilt angle with accelerometer only data.With 303AGR e-compass I can easily configure the filters so a low pass filter can be set up in no time.With LSM6DSL I am a bit lost on where or what filter I...

[LSM6DS3] unbalanced angle

Hello,I use the gyroscope of an LSM6DS3 to command the rotation of a robot. I read the different axis with a 50ms period and I use the gyro internal timestamp to get a precise timing of each sample and I integrate the angular speed using the trapezoi...

AppMEMS#0: how to practically build a high performances, low cost and low power sensor application with ST devices?

Have you ever wondered how to build a working application that consumes little and costs little, but that guarantees high accuracy and meets your desiderata? If so, this series of posts will help you implement your own application with ST sensors, in...

H3LIS331DL output seems not correct

Hi, i'm testing H3LIS331DL and the configuration is as below:Normal mode, 1000Hz sampling, +/-400gSensor data is read by MCU under 1ms timer. If sensor is placed upside or downside, the output value of is verified to be normal (+1/-1g value).However ...
