I have seen on so many sketches the use of sgtl5000_1.volume(n.n) and the use of knob = analogRead(Analog) to manage the volume.
.
My questions are so many. When I use one or the other.? Do I need both.? What controls what? My final goal is to use a touchscreen icon to increase/decrease the vol. but, I am not sure if I still need the Analog pin set up for this purpose. I am running out of pins, or better, I am trying to maximize the use of pins. I have a 3.6, 4.1, and the two audio shields REV C/D. Thanks very much
