Hi!I have followed the tutorial on Youtube.•STM32L4 training: 07.3 Advanced peripherals - Hands-on DFSDM(L476) And now I have some data in playbuff.But I couldn't find any information about the data. Is there anyone knows what kind of format is it? ...
Hi - I'm trying to get a single PDM mic (ST MP34DT01-M) working with an STM32H7, using SAI. It's outputting static when I send the DAC each SAI *freq* interrupt. Some questions:Is the DFSDM peripheral required? If so, what does the value of the SAI x...
Hello,I am working on application that would use microphone array. Together with STM32H735IG board I decided to use STEVAL-MIC001V1 microphone array connected via DFSDM interface. I based my project on example available in CubeMX - DFSDM_AudioRecord ...
Hi, I am evaluating MEMS microphone for our application. I am using on board microphone MP34DT01-M in STM32F779NI-EVAL. I am using DFSDM example in STM32F7cube package and able to hear the speech. Now I want to filter the frequencies higher than 1KHz...
Hi. I have STM32F769i-disco board and i want to execute DFSDM audiorecord example in my board.I have some trouble when executing the DFSDM_audiorecord examples which exists in STM32F769i-eval Board. But i compile it but it doesn't playback..what ...
Board: STM32H747I-DISOSDK: STM32Cube_FW_H7_V1.6.0Pin: PD3(CLK), PC7(DATAIN3)Problem: Filter->DMA bufer OK. HAL_DFSDM_FilterRegConvCpltCallback and HAL_DFSDM_FilterRegConvHalfCpltCallback function enter normally, but the data is wrong(always the same...
Hi,I'm working on a project where I need to make "sound recognition". In my case, I have to detect the nature of an object (paper, metal, glass etc.) based on its sound. To do that I envisage to use deep learning and thus to use the STM32CubeAI p...
I am using STM32F413CG MCU , I'm trying to interface DFSDM to have audio samples to send it to I2SI am running DFSDM audio clock at 61.44MHZ and clock divider is 20 , FOSR = 64 , Sinc 4 Filter , right shift =0 my problem is that DFSDM output array va...
I have a project running successfully for the L4 with a modified version of the X-CUBE-MEMSMIC1 software. I want to port my project to the H743ZIT6. I have the USB audio portion working, but I am struggling with the DFSDM setup. I want the setup to b...
Hi, I am working on STM32F412G Discovery Board to capture audio data from Digital MEMS. For that, I've found an example in the below pathSTM32Cube_FW_F4_V1.24.0\Projects\STM32F412GDiscovery\Examples\DFSDM\DFSDM_AudioRecord\.But I want to write the mi...
