Transfer additional control data in USB Audio 2.0 Reference software

Post by rkn »

Hello,

I have successfully made the USB Audio 2.0 Reference Software working on my hardware prototype.
Everything fine so far.
Now I need to transfer additional data (like channel routing, filter parameters etc.) from my host to the XMOS device. The user should be able to set these parameters by a GUI applications. Any ideas how to make this? My idea would be to add another endpoint and make this a Virtual Com Port or something like this. Is that possible?

Hello. You should be able to do this through the HID interface that is present in the IP:

Here is a stand alone project for the USB HID model that should offer more details for your requirement:
