Hello,I'm using the IMP34DT05 available with the STEVAL-MIC003V1 kit to record audio the nucleo-f401re. I'm using the PDM2PCM library to convert the PDM stream to PCM data. The audio is recorded at 8kHz.I have tried reproducing 1kHz tone on the micro...
On the BL47E-IOT01A2 there are two mems microphones (MP34DT01) both connected to DFSDM1_DATIN2. I'm trying to extract the data from just one of those boards and convert it to PCM using a DFSDM filter. I've configured DFSDM Channel 2 to connect to PDM...
Hi,At Application Note 5027: "Interfacing PDM digital microphones using STM32 MCUs and MPUs" it described how to connect PDM microphone to SPI I/F of STM32. My question is:at SPI I/F clock is active only when there is SPI transaction, how can I caus...
Hi, I spend a lot of days trying to undestanding Microphones_streaming from X-CUBE-MEMSMIC1. That is very complex example and brillant at the same time. I want to extract the part for usb audio in streaming (device to pc), but it is a little crazy. i...
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......
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...
Hi, I connect X-NUCLEO-CCA02M1 to my NUCLEO-F401RE. I am using SPI1 for the communication between devices. For what I have understood the function below convert N bit (for me N = 8) in a integer. Since i want to stream via UART those bit how can i pr...
Hello, I'm working on a project involving voice recognition. So, I used the stm32 sensory library to complete this project and the MP23DB02MM digital MEMS PDM microphone. However, I only found one example that used STM32H747I-DISCO, so I ported it to...
Hello, I am able to successfully compile X-CUBE-MEMSMIC1 (version 5.6.0), UltrasoundFFT for STM32L4R9ZI-STWIN (STEVAL-STWINKT1) - as Debug .bin file. However, when I run it on the STWINKT1, the host Utility/GUI (UltrasoundFFT.exe) does not run. It is...
