LIS3DH high pass filter cutoff frequency for 1344Hz

Hello,I'm working on LIS3DH sensor and trying to configure the HPF in high resolution mode. I couldn't find the cutoff frequency for 1344Hz ODR neither in the datasheet nor application note. Can anyone help me regarding this?

What frequency Should I use for 48khz audio sampling with SAI Interface

I am using a stm32wb55 and I want to acquire PDM data from a MEMS microphone and convert it into PCM. I want to use the SAI PDM interface.I have a doubt about the frequency I should put there :I want to use a decimation of 64. In the reference manual...

STEVAL-MKI197v1 with NUCLEO-F401RE (Expansion board X-Nucleo-IKS01A2)

I implemented the machine learning core on STEVAL-MK197V1 using UNICO-GUI. How can I access this data in F401re?

I'm using STEVAL-MKI182V2 with STEVAL-MKI109V3. So first I tried to check data with the Unico GUI. Then after I integrated the "ism330dlc_read_data_polling.c" example code in my application. But controller is getting stuck while reading the "whoIam regi"

MotionMC does not calibrate my Magnometer in real-time.

Hello everyone,We have successfully setup MotionMC lib in our project in order to calibrate the magnometer embedded in the MPU9250 IMU chip. When the board is turned on, after 15-45 sec (depending on rotating the board), MotionMC calculates the soft&...

Is it possible to receive Bluetooth data as non-root in BlueSTSDK_Python?

The current script in BlueSTSDK examples (https://github.com/STMicroelectronics/BlueSTSDK_Python) needs to be run as root to scan for bluetooth devices in the vicinity. Question is if it is possible to connect to a bluetooth device and receive data w...

How to read and write to SD the iis3dwb sensor at maximum rate?

Hi, I'm using the STEVAL-STWINKT1B development board to read the iis3dwb accellerometer and write to the sd as in the HSdatalog example.To do this I use freertos and fatfs.I created the project first on CubeMx where I set the parameters to read SPI, ...

Hello, Why can I not use 'Program with bootLoader' for FOTA in function packs like 'en.fp-sns-allmems1_firmware_v4.1.0', and 'en.fp-sns-allmems2_v2.1.0' that provide two different binaries?

Hardware: SensorTile.boxThe project readme.txt file suggests that the software should start from the memory address 0x08004000 in FLASH. How can I change this when I am downloading the software from the Android app? The board has to be restarted aft...
