USB AUDIO STM32F401VC DISCOVERY BOARD CRACKING SOUND

[ssena.1514]

Hi,

I have already ported the USB AUDIO DAC application code to STM32F401VC Discovery board. After running the application I am getting noisy audio output from the codec.

Please check it & inform me if you found any mistake(it could be in configuration or audio sync or any other problem) .

And I have also attached the project file.

IDE KEIL MDK ARM

STM32F401VC Discovery Board

Thanks & Regards

Hello @ssena.1514​ ,

I recommend that you try to start with the example provided under our F4 firmware package and update it as needed.

The example is provided under this path: Firmware\Projects\STM32F401-Discovery\Applications\Audio\Audio_playback_and_record

I hope this helps you.

BeST Regards,

Walid

Thanks for replying....​

Actually there is no such example for stm32f401vc discovery board.But for stm32f407 there is such an example. I have also ported this playback & record application to 401 board and it's working fine.

But when I am porting the usb audio example from usb library it's not working correctly(noisy).

I have already verified the application ​& don't know where is the fault actually.

​Whether the fault is in codec or usb side.
