GPIO Mapping for Arcade Project

Wed Oct 26, 2016 9:48 pm

Hello, Raspberry Pi Novice here,

I'm starting bartop arcade project and decided to use a raspberry pi 3 and not sure what to use to connect the joysticks and buttons. Am I able to use the GPIO pins to do this or do I need some sort of USB controller, like an iPAC?
If I can use the GPIO pins is there any delay, if this is a good solution what are is the pin-out for a two player control panel.

Any advice would be greatly received!!!

Are you going to use Retropie?
It sound like you are building a 2-player cab.

I used GPIO (no lag) on my bartop builds using RPI1 & RPI2 for single player, but due to the extra buttons for my 2-player bartop (using RPI3) I used a USB controller. Then you just have a USB cable going to the RPi compared to loads of wires.

There are quite a few USB controller options, KADE, iPAC, clones or even hack a USB keyboard. You can configure all the mame controls to keyboard keys.

Thanks for your reply,
Yes I'm planning to use RetroPie and will be a 2-player cab, I will take a look at the USB controller option!
Sounds like you have built a few of these, are there any pitfalls with controller configuration?

Thanks
