I was wondering, can you record audio via the SAR ADC pins.
The idea is to record audio from an analogue source such as a standard Radio via an Aux cable.
To do this one would need an ADC converter for audio and thus I would like to know if the SAR ADC would work.
I have done this on a RPI, but needed an IQaudio Codec Zero sound card using Alsa mixer and it’s Linux come line function “arecord”.
In summary I would like to know if:
Is this is possible on the Le Potato without an additional Sound Card.
if not would the IQaudio sound card work with this board.
Are there any sound cards compatible with this board.
