[STM32F407-Discovery] Sometimes music is not played through USB Audio.

Hi.I used USB_OTG_FS as Audio Device Class on STM32F407-discovery.I connected PC and STM32F407-discovery with USB device.When I played music, sometimes sound is not occurred on STM32F407-discovery.I found that epnum in USBD_LL_DataOutStage is always ...

Where to download STM32Cube middleware for audio PDM to PCM conversion, from. The pare has a download option , and the option is not active

kindly help me in downloading the STM32 PDM to PCM convertor driver for F4 series microcontroller

X-CUBE-STL - Safe Limited Speed

Hi,I would like to use the X-CUBE-STL on a STM32F446RE to trigger a STO (safe torque off) and a SLS (safe limited speed) with PLc. The STO is no problem at all, since the controller can trigger that directly by using two input GPIOs and one output GP...

Resolved! STM32F407 USB audio stream problem! AUDIO_AudioCmd_FS gets called only once.

Hello everyoneI am trying to implement a simple soundcard from using STM32F407G-DISC1 board.It utilizes STM32F407. I am using CubeIDE version 1.10.1I configured the USB to be Full-speed Device Only. And I configured the middleware as Audio class.I se...

Stereo PDM microphones(2 mics) data acquisition using PDM2PCM middleware, i want to find code example for such situation.

Hello, i would like to know how to use your PDM2PCM middleware for 2 microphones processing data, if you have some examples for it - it would be perfect.I was able to get the good sound for mono(with 1 mic) when i get the board for stereo sound, i ca...

stm32 audio class device, the device cannot start (code 10)

I am trying to stream audio from my PC to my STM32F411CEU (custom development board) with USB. Using STM32CubeMX I configured my MCU as audio device class. When I plug STM32, the PC reckognizes MCU as STM32 Audio Device but there is an error, the dev...

self test for functional test

hii'm firmware engineer and using stm32f4 seriesrecently, i found the st mcu provides a self test libraryso, i has looked into related docs and library files (X-CUBE-CLASSB)but, i can't download any of library files (it's called STL)why?has their pol...

Can I modify the STM32F4 USBD Example to have the device work in 16000 Sample rate instead of 48000?

Hi,I took an example code that implements USBD AUDIO device and ported it to the STM32F411E-Discovery board. Now I can play music from my computer using this board connected to the audio jack.This example works when I set the sample frequency to 4800...

Resolved! STM32F407 Discovery. AudioUSB device. 2 Isochronous USB EP (IN EP and OUT EP) do not work simultaneously

Hi. I am currently trying to implement USB headset on my old STM32F407 Discovery board.In USB descriptor I have simple topology with two input terminals, 2 out terminals and feature unit. Also I describe two streaming interfaces (IN and OUT) and one ...
