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...
Resolved! Question about SAI configuration with a MEMS microphone
I want to connect a MEMS microphone to my stm32 using its SAI interface. I found a document called "Interfacing PDM digital microphones using STM32 MCUs and MPUs" which gives some examples about how to do it.My question is about the configuration :Wh...
Resolved! Question about my code to get data from PDM microphone and convert it to PCM
I'm trying to get data from PDM microphone and convert it to PCM data. This is my first project on stm32 and I'm starting to debug the project. Could you take a quick look at my code and say if you notice something wrong ? Some part of the code come ...
Resolved! Unable to convert PDM data to PCM data using pdm2pcm
I'm using a stm32wb55RG. I'm trying to get data from a MEMS PDM microphone and convert it into PCM data. I'm using SAI PDM interface and DMA. So far, I think I manage to receive the PDM data (I get some values from the SAI interface) :I don't know if...

1. Does the MotionDI library output the gravitational acceleration along with linear acceleration as I am getting it in the lin acc. data? 2. How to wipe out the effect of gravitational acceleration in linear acceleration? Sensortile kit is used.
Sensortile kit is used and linear acceleration is fused output from gyroscope and accelerometer,the sensor is kept with z-axis of accelerometer being parallel to gravity (screenshot attached).
LSM6DSM on SensorTile using SPI?
I would like to know what I am doing wrong or what register setting on the LSM6DSM that I missed setting?Using a sensorTile (STM32L476JG) that is connected to LSM6DSM. APB1 Clk = 16MHz.My settings are : My code is trying to read WHO_AM_I register on...
