USBX Audio Class Microphone example

[nico23]

Hi,

I've implemented a USBX Audio device correctly using ThreadX and the USBX Middleware on an STM32U5 (working as a speaker).

I would like now, to implement a microphone using the same USBX Middleware. For that, I would like to figure out if there are some sort of examples where the microphone is implemented (including device descriptors).

I'm seeing this old conversation https://community.st.com/t5/stm32-mcus-products/usbx-mic-streaming-on-wba65/m-p/851912#M288041, but no follow-up has been provided.

I don't mind an example of any other microcontroller, but I would really love to see it implemented with USBX Middleware

Thanks

No one knows?

Hi @nico23 

I got the information. Recording example will be available in next release of x cube H7

Do we have an ETA?

Thanks

Hi @nico23,

Apologies, but I can't share an exact ETA on the forum. However, the release is expected to be available approximately by Q1 2026.
