hy,
I would like to use your NUCLEO-F446RE board platform with X-NUCLEO-CCA01M1 and X-NUCLEO-CCA02M1 expansion board, using the FP-AUD-SMARTMIC1 software.
In reality we have a configuration like the figure in the annex
where external codecs are not used but only the adc and dac internal to the micro.
Is there anything more suitable? it would seem so, as explained in your AN2812 application with analogue microphones. Are there more nearby boards or demo boards more suitable for using open source firmware as an echo canceller?
