Switch on/off GPIO buttons plugin v0.8.1

Help and Support

Hello,

I’ve build a Volumio player with a Raspberry Pi4, the 7 inch RP touch screen and the Hifiberry DAC2 pro.
Using a RF usb remote control for controle volume, next track etc.

After installing the GPIO buttons plugin v0.8.1 I’m trying the switch on/of Volumio with a push button normally open/closed using GPIO 17 and a ground pin.

Making en short connection between GPIO 17 and ground does not trigger any event.

lack of substantive knowledge at my side but can someone help me on how to implement it?

thanks in advanced

I don’t know if gpio pin number 3 can be used with the Hifiberry DAC2 pro, try it then reboot and check if it works now.

Wouldn’t go there…
GPIO2-3 (pins 3 and 5) are used by our for configuration
GPIOs 18-21 (pins 12, 35, 38 and 40) are used for the sound interface

I guess you have this DAC:

Then no, GPIO03 is already used by the DAC

Sorry late update,
I already manage to work this dac together with touch screen on my raspberry pi 4.
