Hello,
I´d like to do some FFT tests. I don´t have an Audio Adaptor Board.
So, how to start? I found the Audio System Design Tool for Teensy Audio Library. I guess there I have to connect the ADC input to the fft256 analyze module.
Copy the code into the Arduino IDE and try to adapt the FFT example.
Hardware: The audio input into the circuit as described in the Audio System Design Tool information - 4 restistors, 2 capacitors, input to A2.
Is there any obvious mistake in this plan? Or an important step I missed so far?
Thanks for any hint!
Stefan
