Calibration using MotionAcc library
I am using the industrial IIS2DH accelerometer in our vibration analysis product. I am collected data using the data-ready interrupt. For improving data accuracy I want to perform some calibration on data. I have found the following document. "Gettin...
Problem with enabling onboard MEMS microphone using SAI interface on STM32H735IG discovery board
/* SAI configured in Mode: Pulse Width Modulation using MicroPhones pairs (1-2) and CK2 as clock */ static void MX_SAI4_Init(void) { hsai_BlockA4.Instance = SAI4_Block_A; hsai_BlockA4.Init.Protocol = SAI_FREE_PROTOCOL; hsai_BlockA4.Init.AudioMo...
Resolved! LIS3MDL Power Down Mode Issue
Hi,We are using LIS3MDL in our application and current consumption in Power-Down mode is 0.2mA which is quite high but it should be 1uA as per the datasheet.Any suggestion on why I am unable to achieve 1uA level as mentioned in the data sheet?Regards...
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...
