Hi,
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.
