Resolved! Hello ST Experts , I have a three VM3000 PDM mems interfaced to a STM32f745IETx controller , via I2S2, I2S1 lines and another in SAI2_SAIB block , how do I configure three such in programming while using PDM2PCM middleware , can anybody help me ?

The help will be greatly appreciated . I have to write this raw data extraction of PCM values in onto sdmmc sd card . And could anyone explain me how does the PDM2PCM functions for the mems than ST PDM microphones? I usually find examples of stm32 co...

STM32CUBEMX- Error while Analyzing the model.

Hi ST Member, Am getting the following error while Analyzing the model file in Stm32CubeMx."ImportError: cannot import name 'get_all_providers' from 'onnxruntime.capi._pybind_state' (C:\Users\Systemname\STM32Cube\Repository\Packs\STMicroelectronics\...

Resolved! Hello all, 1)How to calculate the dB SPL for a MEMS mic captured PCM values in a log file .?? What are the in particular parameters of the mic ics43432 ? 2)How do we add the acoustic_dB library to a STM32f4xx ?

My second question continues to be the how can this PCM value be converted to .wav format?i still need a deeper understanding into this domain , anybody over here can post suggestions ,links technical articles and can share their experiences for my l...

Resolved! Hello Experts of ST community, I have mems mic and stm32f4xx nucleo board and collected the pcm format data in a log files. Now my query is how to convert them into .WAV format ? and How to validate the the values are exactly accurate?

Can someone help me figuring out how do we conclude the obtain pcm values are accurate and can there be any references to validate it and test it back?Any suggestions please help?

Hello experts , I have a query on how to acquire a PCM audio 2000 to 4000 samples nearly from a PDM out conversion of a MEMS mic and display them on UART/USART for every 2 or 5 seconds? Can any expert help me with a coding part. Thanks in advance

MEMS mic -ICS43432+ STM32f4xx nucleo board.i have given a 168MHz HSE clock configuration and used a PDM2PCM middleware too with a 32KHz audio frequency with I2S in master receive mode. and DMA in SPI2_RX DMA1 Stream 3, in the STM32Cube MX.The oscillo...

Resolved! Hello ST Experts , I am new to STM32 development environment i had a query regarding how to interface MEMS microphone ics43432 with STM32F4xx nucleo 64 board , their clocking configurations in STM32cubeMX and the usage of PDM2PCM middleware.

The 1 bit PDM data output should be converted to a 16 bit PCM data format using this and what peripherals should be used in STM32cubeMX and the obtained PCM should be converted into .wav file and display it on UART/USARTWhat is the process could anyo...
