Will AUDIO class support UAC2? #19

Closed xu-yingjing closed 1 week ago

xu-yingjing commented 3 weeks ago

Hello,

I'm using this library on STM32H7RS's project to implement a USB sound device. The STM32H7RS has USB_OTG_HS ip and internal HS Phy, so it can easily achieve USB high speed. However, this library implements USB AUDIO Class based on UAC1.0 which does not support USB High Speed.

Hi @xu-yingjing,

Your question has been forwarded to our development teams. I will get back to you as soon as I have their answer.

With regards,

Hi @xu-yingjing,

According to our development teams, the so called classic core USB library only supports the UAC 1.0. In case you need UAC 2.0, please move to the USBX library.

You can find the library in this repository. STM32H7RS applications can be found here.

With regards,
