What kind of microphone you plan to use?
If analog mic, you can use the Delta Sigma.
If digital microphone, you could interface using I2S or PDM, both blocks can be implemented in UDBs.
Analog mic I want to connect.But mic does not have USB.
Hi, have a similar question, i have a KY 038, an unknown 3 pin mic, and Electret mic, i have tried those 3 mics with The Delta Sigma, but nothing, not even noise, I know those mics are working properly because I tested them on an Arduino,
This is for a DTMF decoder, I've teste with wires adn it works fine, but with those mic is a completely different history.
