BSP_AUDIO_OUT_Play() Buffer Size Parameter

I am programming an SMT32F69I-DISCO board to output a SINE wave. I am having trouble with the Size parameter of the BSP_AUDIO_OUT_Play() function. I have a buffer of 100 that I am filling with my SINE values:int16_t dataI2S[100];Here are my calls of...

How to properly use a driver file / How to send sound to Line Out [STM32F769I-DISCO]

Hello, I'm quite a newbie and I'm sorry if I don't understand something simple :\STM32CubeIDE 1.7.0, STM32CubeMX 6.3.0I would like to make a simple synthesizer on STM32F769I-DISCO. Right now I managed to modify the example repository "STM32Cube_FW_F7...

Resolved! F7: SAI 24 bit audio samples to SRAM via DMA in bytes?

Hello,I'm trying to get some audio samples with 24 bit resolution from the SAI (RX, connected to an external ADC) into SRAM via DMA.When DMA data sizes / alignments are set to WORD (32bit) for peripheral and memory everything works fine.To save some ...

Best way to sample ADC at 48kHz for buffer manipulations (FFT, etc)?

I'm trying to make a guitar pedal using the ADC on my F767ZI. I want to be able to perform an FFT and other functions on a buffer of data sampled at 48kHz.I wanted to use the ADC DMAs and use the equation Tconv = 12.5cycles + SampleTime, but I have n...

STM32F7508-DK not supporting the audio input?

Hi,I'm wondering why the STM32CubeF7 1.16.1 package only supports "microphone 2" (INPUT_DEVICE_DIGITAL_MICROPHONE_2) within stm32f7508_discovery_audio.c / BSP_AUDIO_IN_OUT_Init() ?Is there a technical reason to do so?I would like to record audio thro...

How to set DFSDM Configuration so that LPF cut-off frequency is 1 KHz on MP34DT01-M using STM32F779NI-EVAL?

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...

[STM32F769I-EVAL] Can I use both the Audio and Ethernet functionalities at the same time on an application?

So this question arises because the jumpers 3 and 6 of the board switch between either Audio or Ethernet, and I'm not sure in what capacity they're mutually exclusive or not.As an example imagine an application for audio streaming over Ethernet:can I...

Hello Experts Could anyone suggest me how to convert the raw PCM values received in log file be to mp3 or .wav formats .And if there any libraries that could be included or any method? after conversion storing that into sdmmc and play that as loopback?

The Acquired PDM signal is from VM3000 mic and PDM2PCM conversion using stm32f745?could the acquired values be played as loopback to verify whether the acquired sound is in audible frequency to human ears? How could this be validated? all suggestions...
