USB Audio device programming
I have a custom board using a PDM output digital mic running into the CY8C5667LTI-LP009 MCU. I use a slightly edited version of the source code found here. I programmed the MCU using the MiniProg3 over SWD with the Cypress Programmer 3.23.1 and it all seemed to go smoothly. However, when I plug in the board via USB to a mac or PC the thing doesn't enumerate. Does anyone have any nuggets of info on why this might be happening?
Is there some special way to program the MCU so that it will enumerate as a USB audio device or should it work when programmed the way I mention?
Ive attached the schematic in case that helps.
Any help would be much appreciated and virtual beer tokens can be sent!
