Hi there,
I have an old Denon tuner that I would like to convert into a network streamer.
It will then have room for a RaspberryPI with a DAC and a power supply unit.
The plan is to replace the current display with one of the small, inexpensive OLED displays and continue to use the current buttons.
Now to my actual question:
I have found the circuit diagram for the button board and all but one (which ins’t important) of the 16 buttons are arranged as a 4x4 matrix.
Is it possible to manage such a buttonboard with the GPIO plugin or only individual buttons?
Thank you very much for your help.
