MEMS (sensors)

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...

LIS2DE12 - What is low-power mode

Hi,Can some one explain what is low power mode. It is mentioned in page 45 in the data sheet. But no where it is explained. I would like it to work in low power mode and wake up on certain condition (also cause INTERRUPT) and go back to low power mod...

LIS2DE12: Movement detection over interrupt question

Hello there,I have a question about this sensor. I'll be using it as a low-power device on a PIC, which is most of the time in sleep mode, and will wake up on interrupts from various devices. I want to configure this sensor so it will notify the PIC ...

Problems with X-CUBE-MEMS1 and STM32CubeMX integration

Hi, I am following the guide "Getting started with the STMicroelectronics X-CUBE-MEMS1 software package for STM32CubeMX" to try the example "DataLog" with the X-NUCLEO-IKS01A2 and the NUCLEO-L4R5ZI-P. I am using a MacBook Pro with STMCubeMX 4.26.1 an...

SelfTest functionality followed Application Note AN-5005, using LIS2DH12. What is the MIN ST_X and MAX ST_X mean in the Application note AN5005?

LIS2DH12 is Configured with BDU=1, Normal Mode, FS=2G. While doing the below step after collecting the data, in non-selftest mode and self mode. We followed the steps detailed in the Application Note AN-5005 and each axis has to be checked as below|M...

LIS2DH12 what is the range of values that is expected in x, y and z axis? We have Configured the LIS2DH12 in the normal mode
