I am trying to run AcousticBF (Beamforming library v3.1.0 from XCUBE_SMARTMIC_V2.4.0 pack) on STM32H747 development board, but on the output I get only a tone signal, and no audio hearable from Mics. - The inputs are two PDM mics, and the PDM signal ...

I know that the library X-CUBE-AUDIO is not compatible with H7 series (only F4 and F7 is supported), but it can be very useful on the H7 mcu, too.Is there any way to make it run on the H747 cpu on M7 core?I want to use mainly SVC (SmartVolume) functi...

Hello, I trying to trace audio signal by SWV Data Trace Timeline graph? I cant do it. I can show normally only 10Hz signal. Higher frequency signals make a mismatch in timeline graph. I m using STM32F769 mcu, with coreClock: 216Mhz, SWO Clock: 2000kH...

Update:Now I can precompile the beamforming sources without any warnings, but the output is still only a signal tone.

Create Source Folder for filesystem where source files are available, instead of simple folder. See attachement.Right click on project - New - Source FolderAnd now the compiler can find the source files in Source Folder

I have tried this, but still not works.And I have tried to initialize the SDR (Sound Detector) from the same X-Cube-Audio library pack, but it also returns the same error.

Hello,After enabling crc peripheral by __HAL_RCC_CRC_CLK_ENABLE(); I have tried to call hcrc.Instance->CR |= CRC_CR_RESET; or __HAL_RCC_CRC_FORCE_RESET(); but function pSvcPersistentMem = malloc(svc_persistent_mem_size); pSvcScratchMem = malloc(s...

STM32H747 - Use SVC (SmartVolume control) from X-CUBE-AUDIO lib

Is there a way to use ST AcousticBF from X-CUBE-MEMSMIC1 lib in PDM mode, to use together with dfsdm peripheral? We can also use SAI peripheral, for 4-6 microphones. So what is better SAI or DFSDM?

Which is the highest frequency signal that the SWV Data Trace Timeline graph can show?
