I’ve got my RPi set up. It’s awesome. I’m using a USB SNES pad, and it works really well. The the moment I have to use a keyboard to quit out of games. I want to use a GPIO button, like on the “RetroPie GPIO Adapter”.
Am I correct in that I should be connecting to pin 16 (GPIO 23)? 23 has a low pull down, so do I just connect a 1k ohm resistor and a push button to 3v3?
So I’ve gone ahead and given it a go. And it doesn’t do anything, so it’s not set up by default. I’ve searched high and low for the code, and I can’t be the first person to ask about this. Can anyone help me?
