I got my Teensy 3.1 with Audio Board working, however one thing I would like to accomplish is determining dbu values from the line in. (Accurate VU meters)
Is this even possible with the library at all?
I was able to do this with an Arduino Uno and voltage divider (5v -> 2.5v) on the ADC to get good results there. Unfortunately the Arduino Uno is a bit slow with the ST7735 LCD. AFAIK the Teensy 3.1 cannot take in 5V for analog reference can it? (Would blow it up?).
I think I killed a 2nd Teensy I have as well It is no longer recognized by the PC at all.
