Indicating the sample rate and format


#1

I wonder how difficult it would be to indicate the incoming sound’s sample rate and format (PCM/DSD) by the board. The OLED connection is only a pass-through from VIM’s PIN header, so the Tone Board cannot use it itself.

It could be enough to connect some LEDs to the XMOS, but the firmware would need to be modified, I suppose. There is probably not enough free I/O pins available to indicate all the combinations, so that some multiplexor would probably be needed?
