Feasibility of USB UAC Transmission with nRF52833 and Example Inquiry

[deep_dive]

I have connected a Digital MIC to the nRF52833 and aim to transmit the voice data captured by the MIC via USB 2.0 Audio Class (UAC).

Upon consulting with the agency, they confirmed that while the nRF52833 does possess the necessary functionality to achieve this, there are currently no available examples or code snippets to guide implementation.

To clarify my understanding, I have the following questions:

1. Is it possible to transmit MIC-captured audio data using USB UAC with the nRF52833?

2. Are there any existing examples or sample code available for this specific implementation?

There is a sample headset for UAC1 that have only UAC1 audio IN and not playback. This is something you most likely wont be able to run on nRF52833 due to the limitations of memory on this variant.

I want to clarify something. You said, 'There is a sample headset for UAC1 that has only UAC1 audio IN and not playback.' Does that mean that the speaker output works but the microphone input does not? You mentioned that both are possible through the test, but I want to be clear about which one is fundamentally supported between the speaker and the mic. According to you, there could be issues due to the limitations of memory on this variant, so I want to clearly understand what is fundamentally possible.
