MEMS (sensors)

Choice of cost-sensitive microcontroller(possibly STM8L) to control 868MHz wireless sensor module with battery power - "home safety".

Types of sensors: "water leak", "temperature / fire", "gas leak", "PIR" and "AC leakage". The sensor module will connect to the LoRa transceiver (+ MCU): ATSAMR34/R35 (Atmel).

VL53L1´S API implementation for Microchip devices: Doubts.

Hi friends,I´m trying to include a Vl53l1 in my project. I am working with a PIC32MX440 microntroller.I have filled with correct functions in the files vl53l1_platfom.h and .c to use the APIs with my hardware.The commication with the sensor is right...

In ISM330DLC, is odr equals to smaling frequency? if not how to calculate the sampling frequency to calculate the FFT

What should we consider as sampling frequency to perform vibration analysis using ISM330DLC?

Hi, we are using ST ISM330DLC for measuring vibration. Our main aim is to capture accelerometer data and perform frequency analysis by computing FFT (1K and 2K points). However, we are not able to identify the sampling frequency. What should we consi...

In the release log of acoustic BF (V2.1.2 / 04-Oct-2018) it says: "Bug fixed for microphone distance" What exactly was the bug and what exactly changed?

H3LIS331DL sensor readings do not change

I'm using the STEVAL-MKI153V1 evalulation board together with a Nucleo F443RE board and the STM reference driver implementation from github.The code is basically the read_simple.c example provided by STM adapted to mbed.I've checked the I²C communica...

Device Tree Initialization of RTC M41T80 Clock-Provider

Hi everyone,we are using an M41T80 RTC on our custom linux board. This RTC has a CLK-OUT feature which is per default to ON and 32kHz. We have another chip wired and depending to that clock signal.On kernel version 4.1.15 there was no feature to enab...

Is there any sequence that should be done before reading the registers value on LIS3DHH accelerometer?

Hello,I try run accelerometer LIS3DHH on Nucleo F411RE. I want check register WHO_AM_I value. I set address on 0x8F (0x0F address register and 0x10 value as set accelerometer to read data from register.) I always receive value 0x00 from register. I r...

LSM6DS3 3D Gyroscope best ODR Selection

Hello all,We have interfaced LSM6DS3 with a wireless microcontroller by I2C for .I want to know how do I select the best ODR value?Is there any standard methods for selecting ODR?According to datasheet I found that if ODR is high the current consumpt...
