I am finishing up my streamer project and I have added 3 hard buttons on my front panel. I have assigned two for web radios with the “GPIO Radio Buttons” plugin and they worked properly. I then assigned the third button for calling the random playlist with the " Gpio Random" plugin, but pressing the button gets no response at all.
I cannot use gpio3 as said in the example of the plugin, because my I2S dac card is occupying this pin, so I use gpio 26 instead. But I don’t quite understand the “pins with interrupt” as recommended in the plugin. Isn’t the interrupt of pins assignable and already assigned when Volumio boots up? So, is there a default gpio pinout list with such?
This is the last step of my project, and I hope somebody can help me with this plugin, thanks.
