I’ve managed to get a rotary encoder for volume with it’s click button for mute working and started wondering what my options are for adding another rotary encoders or buttons to the board. I’ve essentially used up the GPIO pins on the DAC. I would like to be able to move through the queue and possibly power the system up and down.
I’ve searched hi and low only to find others looking for the same answers. I basically need to know what PI GPIO pins are available and how to connect components to them with the Digiamp plugged into the RPI. I’m still very new to all of this so please bear with me.
Thanks in advance.
