Tool/software:
Hi,
I am looking for a solution to wake up my system from sleep state with a digital audio signal.
With analog inputs of the pcm1863 it works without any problem using the energysense interupts.
Would it be possible to set GPIO1 to DIN and use the DIN RX toggle interupt to detect if there is anything playing on the spdif input of my board ?
Or is it just possible to detect a pin toggle and not actually if there is any music playing, since spdif is not only zeros if nothing is playing?
Thanks in advance!
Sebastian
