The MK-312 supports 3 audio modes I’m guessing
- Audio1: Mic/Mono input sampled through the ADC
- Audio2: Stereo Input sampled through the ADC
- Audio3: Stereo input routed to a comparator / schmitt trigger and into INT0 & INT1
Has anyone compared a physical MK-312BT to ‘the other one’ in a “side by side” comparison to see if these are functionally and performance wise identical ?
The component values in the Audio chain seem very high in the MK312 and simulations are not working.
AFAIK the LM324 model is correct, Tested it with some basic op-amp circuits and gave expected results.
But I am human and could have misread some stuff in building the audio path
Any input here is welcome.
