SensorTile.box and Nucleo IDB05A1

Have you a sample code in mbed for read value of accelerometer characteristic from SensorTile.box with X-Nucleo IDB05A1

FIFO usage and sample storage based on interrupt.

Hi, I am using LSM6DS3TR-C sensor. In my application, I require two buffers to store MEMS samples. One buffer contains data before the event and second buffer after the event.Currently, I am using continuous-to-FIFO mode for my application and two in...

Can I use calculated "MLC Features" of the LSM6DSOX in an application processor?

The LSM6DSOX offers a MLC that calculates powerful features like mean, variance, energy, etc.I did not see a way to just read them from an application processor and use them in my own application. Is it possible to access the results of the feature c...

Regarding LSM6DSLTR. Do you see any problems with lack of data or readouts from LSM6DSLTR. See further decription in the "Details box" below

Dear STM Sensor specialist ..I have a customer who up until now have used 1 LSM6DSLTR on his powerboard.Now they designed a new powerboard with 2 pcs LSM6DSLTR and now they are facing some read out issues.Electrically it is a copy of the old design ...

Audio sampling rate mp34dt05-a

I am using the mp34dt05-a mems microphone and receive the PDMdata stream. Now I want to do the signal processing as recommended in application note AN5027: "Interfacing PDM digital microphones using STM32 MCUs and MPUs". Thus after receiving the PDM ...

Where to report bugs for sensortile.box?

Hi, just want to give some reply on "bugs" I found in my sensortile.box.1. Battery capacity always showing 0% even after loading for 2 days and voltage is showing 3.9V2. The date of my logfiles jumped from 31.12.2019 to 01.01.2000. :)3. The csv files...

Resolved! FIFO usage and tap interrupt.

Hi, I am working with LSM6DS3TR sensor and need some advice on FIFO usage. I have followed sample code from the ST's GitHub page but still have some questions. I am using continuous-to-FIFO mode and tap interrupt.I see samples on my screen when inter...

Resolved! Calibration LSM303 DLHC Magnetometer

Dear friends, help me please solve the problem that I encountered during the calibration of the LSM303 DLHC magnetometer. I use the technical documentation stm32 AN3192 for calibration. After rotation of the sensor along each axis and data collection...

What is the significance of Window Length while making a MLC configuration?

I know the theoretical values of sample length and window length. However, I do not know if this parameter is linked to the Accelerometer ODR, or the MLC ODR. Currently, my MLC is at 104 Hz, while my Accelerometer ODR is at 6666 Hz. What calculation/...

Is a 10 seconds initial period needed to read correct PDM data?

We have a IMP34DT05 interfaced with a STM32L486 on PDM. We are observing that, after the clock to the MEMS is enabled and the sampling is started, in the first 10 seconds unexpected db values are calculated (higher than expected: 80 db). Then, the v...
