X-CUBE-USB-AUDIO Sychronization Characteristic

[ESawa.1]

Hello together,

i'm using the X-CUDE-USB-AUDIO expansion pack with the Development Board STM32F769 Discovery Kit. We plan to integrate it later on into our product. The example project for playback and recording works fine. But we wonder which synchronization pattern is used in those examples?

We checked the manual UM2195 and USB offeres 3 modes (Asynchronous, Synchronous, Adaptive) there it seems that the devices runs in "Asynchronous" mode. Is this really the case? Is this mode supported by native OS drivers on MAC and Windows (Adative Driver), or do we need to write one on our own?

Best regards,

Eric
