Hi all,
I think I have a ground problem. I have a Teensy 3.2 and audio adapter set-up as seen in the image. The touch pads work when plugged into USB power or if i touch a ground connection or some parts of the circuit (the 1/4 jack socket, the side of the screen etc).
I did read in another post Paul asked what happened when you touch a wire (gently) from the ground on the teensy to the ground on the audio output (in this case the mono audio amp out to the speaker) and this make the circuit crackle and die.
Is there any way to make this work without adding a ground wire that you have to touch as well as the pad or doing capacitive sensing with 2 pins instead of the touch pins?
What am I missing?
Thanks,
Asha
