DM2PCM library for STM32WL microcontrollers missing

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

IIS3DWBTR Filter LPF2 frecuency response

Hello Community,We have been using the IIS3DWBTR sensor for some time and have observed some odd behavior regarding filters. We recently performed some experimental tests on the LPF2 Filter to corroborate the frequency response curves on page 20 of t...
