LIS2DH Raw output data noisy
I am reading the 3-axis data while turning on Inverter and cold cathode tube.The 3-axis data is too noisy. Is LIS2DH affected by external noise?Also, How can i reduce the noise on the raw data? (e.g. Exrta sheelding)

Problem while programming with Algo builder
Hi,I use Algo Builder to test the sensortile.box, but I can't program the board using the algobuilder software (after I have compiled) in order to test the functionality, even if it seems to be possible to program the microprocessor using directly ...
Resolved! What is happening in time-domain output if the Low pass filter (LPF2) of iis3dwb was set to 1333 Hz?
What is happening on vibration data output in time-domain if the low pass filter (LPF2) of iis3dwb was set to 1333 Hz? Does the vibration data output in time-domain cannot show any vibration data of 6.3 kHz frequency? Please advise. Thanks!
Hi, I can't use the MP34DT01 built-in microphone of the B-L475E-IOT01A board. Does anyone know how to do it?
Hi, I'm developing my first project on an embedded system, more specifically I'm using the B-L475E-IOT01A board. My idea is to use the MP34DT01 built-in microphone but I'm having a number of problems:BPS audio drivers for the board do not seem to be ...
LIS3MDL large power consumption
Posted on June 22, 2016 at 19:45I am using the LIS3MDL magnetometer on a custom PCB I recently designed. In addition to the sensor, the PCB has an STM32F101 and a HopeRF LoRa radio. I am measuring current consumption by the LIS3MDL much larger tha...
Resolved! LIS2DH questions
I have a project with LIS2DH accelerometer and I want to measure values each 20 seconds, turning LIS2DH off between measurements.So, I tried to turn power on, wait 5ms, write 0x10 to CTRL_REG3 (turn on DRDY on INT1), then 0x1F to CTRL_REG1.Then I wai...
Is it possible to extend a linux driver to support software triggers over their existing hardware interrupt ?
Hi all, I am currently attempting to extended support to the lsm6ds linux driver(https://github.com/raspberrypi/linux/tree/rpi-5.10.y/drivers/iio/imu/st_lsm6dsx) which supports the ISM330DHCX. It currently supports interrupt based buffering. I'd like...
Why does LPS25HB show wrong pressure value?
I'm using LPS25HB in my card. I can take correct temperature value but I can't draw pressure data as correctly. It show me that my Pressure is approximately 500 hpa but actually my pressure value is approximately 500 hpa. Is there any solution for th...
Resolved! How to use IIO triggered buffer?
I use ASM330LHH as Linux IIO.Source and DTS were added.We found that /sys/bus/iio also added a device.I also checked reading data in direct mode from sysfs.Therefore, I think there is no problem with the H/W connection.I want to use Trigger mode to ...
