Hi Folks,
yesterday I received my first Teensy4.1 (after using ++2.0 for long time) and i was very excited to try out the audio libary. In the end, I was very frustrated and now I hope you can help!
I was trying the Example > Audio > Analysis > PeakMeterMono with the input at A2/16, but serial monitor shows nothing. I put a "Serial.print("AAA");" after the first "if(fps > 24)" and it was printed. If I put it after the 2nd if (peak1.available(), it's not printed.
I tryed the advised circuit but also a funktion generator with adjustable offset without any result. On the serial monitor just happens nothing.
After I made a test with the example "readPin" and this was working very fine. I supplyed an external DC Voltade to Pin 16 and got plausible values at the serial monitor. So the pin A2/16 and ADC seems to be ok.
Do you have any ideas? I really have no plan what to do.
Thanks a lot!
Regards from Germany,
Ben
