Hello Everyone!I am working on a project with 4 mems microphone and I want to get the estimated angle (sound source localization) using Acoustic SL library, but I don't know how to get it?I have Nucleo-F401RE board and I want to locate sound source w...
Hello!I want to interface 4 PDM microphones with STM32F401RE's SPIs in stereo config(like in the pic above), I have a problem of how to get its data using pdm to pcm library. As the data will be alligned in this form(M1bit1, M2bit1, M1bit2, M2bit2......
Hello!I am working on a project with 4 mems microphones and I want to get the angle of sound(sound source localization) using xcubememsicmic1 sound expansion pack but I don't know how can I get it?Anyone who has experience in mems technology and soun...
Please help me. I am trying to configure pins for reading the data coming from 2 microphones mount in a X-NUCLEO-CCA02M2. To read the data I am using a NUCLEO-F401RE. I read all the documentation for tthe expansion but nothing is working. In this mom...
Hello!I need to interface 4 PDM microphones with Nucleo-F401RE(I2S1 and I2S2) in stereo mode.Is it possible to connect 4 PDM microphones with F401RE?Please provide me with a simple circuit diagram and a sample code to how to get data from these mics ...
To make a successful read via the spi bus of the fifo in rouding mode should return 7 bytes, the tag byte plus 3 words but the device does not return correct data or count as a successful fifo (and update the fifo size). What data is returned is rubb...

The LSM6DS3's datasheet recommends setting BDU=0 for the FIFO's status and data registers, which makes sense in my opinion.The LSM6DS33's datasheet recommends setting BDU=1 for the same register block, however. I can't find any recommendations for s...
I am using two PDM microphones(mems transducer) with STM32 to measure the intensity and if the intensity of the left microphone is higher than the right one then an LED should turn on and vice versa.We measure the intensity of analog signals like whe...
