stm32f2 usb sound card

I want to develop USB streaming sound card using stm32F2xx series.

I can use stm32cubeMx and AC6 sw4stm32, but cannot use other IDE.

I found,

- UM0424 STM32F10XXX 

- STM3210B-EVAL - STM3210E-EVAL - STM32L152-EVAL- STEVAL-CCA021V1 

- AN2739 F103 

But all of these sample sources can not use in sw4stm32. 

The stm32cubeMX code works well enumeration USB audio class, but the PC's streaming sound are not arriving on my board.

I want to catch the streaming data from PC in the endpoint 1(out), but anything not arrived.

Please let me know the best, short way what I can do.

Or let me know the AC6 

sw4stm32 sample code of USB sound card sample source.

Tks.

Hi

‌,

Welcome to the STM32 Forum, hope you will find here all what you need as help. Then don't hesitate to share your knowledge with other member

Please note that there is already a ready to use example for Audio application in the package STM32CubeF2.

As described in its readme.txt file: it is aa typical application on how to use the STM32F2xx USB OTG Device peripheral and I2S peripheral to stream audio data from USB Host to the audio codec implemented on the STM322xG-EVAL board.

You find the SW4STM32 example in this path:STM32Cube_FW_F2_V1.4.0\Projects\STM322xG_EVAL\Applications\USB_Device\AUDIO_Standalone\SW4STM32\STM322xG-EVAL_USBD-FS.
