You have USB cntrolle and ADDITIONALY you wired few buttons to GPIO?
Ok, when i install gpioneer does it affect usb buttons in any way? (so, when i have my usb joystick and buttons perfectly configured and i install gpioneer it will not switch off usb buttons? – so i can use usb for joystick and buttons and ONLY two flipper buttons wired GPIO ADDITIONALLY?
It’s not USB OR GPIO ?
And does it matter which gpio pins i connect to side flipper buttons?
Once installed, you just type in the URL of the pi, and it will bring up the GPIOneer configurator to program your buttons. What’s nice is you can change them at any time very simply. Your other choice is retrogame. It does basically the same thing as GPIOneer, but it is not as flexible.
