    USB Audio Class 2 for PSOC5?

    user_274318315

      Hello. Mightily impressed by the 5LP development kit and PSOC Creator.

         

      I am trying to write a modest bit of firmware for a USB audio class 2 compliant device for use with Apple hosts. Yes, I know I could use class 1 given the full-speed only capabilities of the PSOC5, but I need to make this UAC2 compliant.

         

      There are some questions arising:

         

      1. Does anyone have a working UAC2 example?

         

      2. The audio descriptors list in 'Configure USBFS' appears to be missing a UAC2 Type 1 format type descriptor as defined in section 2.3.1.6 of the Frmts20 final document*. Is there a way to add to new custom descriptor template to the USBFS configuration tool? 

         

      3. If the answer to 3 is no, what is the best way to incorporate a new descriptor format? I'm loathe to modify machine generated code ... 

         

      Any help welcomed.

         

      BR.
