MEMS (sensors)

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...

Dear @Imen DAHMEN​ ,Is there any plan to have the PDM2PCM library in the Middleware for STM32WL microcontrollers?Thank you much.

LIS2DE12 - is it possible to set & reset INT1 & INT2 pins (or any other pin) on wakeup

Hi, I was looking at LIS2DE12 and I am aware that it can send a wakeup signal to the CPU. In my design I want to enable the power on PMIC chip directly through its enable pin. So I want to do something like this:Shake the deviceLIS2DE12 sets its pin ...

Hi 1. Is there a way to extract out the gravitational acceleration from accelerometer reading using MotionDI library? 2. what does the gravitational vector signify in MotionDI library output?

I just want to measure the translational acceleration and wipe out the effect of gravitational acceleration from the accelerometer reading. I know this can't be done with accelerometer alone, but can it be done with MotionDI library which uses both t...

How to import stm32 PCM data into my computer

I'm trying to convert a PDM data stream from a MEMS microphone into PCM. I think I managed to get a code working and now I want to verify that the acquisition is good. In my test code, I store all the PCM data into "uint16_t pcm_data[30000];"While in...

I have two stm32 boards STM32F103ZE and STM32F103RC I am trying to use an ultrasonic sensor in a project, the code works on the STM32F103RC board and but doesn't work on the other, I changed configuration and pins but still nothing, what could cause this
