Device firmware for 16 channel class 2 audio

simmania — Sun, 24 Jan 2021 20:53:27 GMT

Hi,
We are investigating if we can use a i.MXRT MCU for our product. This product will include 16 channel audio output. So we need USB firmware that supports class 2 audio output.

We have seen the 'Composite CDC (serial COM) + 2-channel audio input / output' example. This seems to be an interresting starting point. But is this easily adaptable to 16 channels?

Hi simmania,

No, there isn't such examples which use more than two channel.

Regards,

Jing

Will it be easy to adapt the 2 channel example to 16 channels? Like changing a few constants from 2 to 16? And off course taking care of the audio samples.
