GPIO is over my head!

[powelly52]

Im trying to use a snes gamepads PCB as a hardwired controller into the Raspi Zero's GPIO pins.

so far i have each button wired to a useable pin and a shared ground wired to the ground.

i have retropie installed and running rom's which work fine with a keyboard inserted.


from what I've read i need a driver to make the GPIO pins register the button presses as inputs for emulation station to read as up down A B Ect.

i have tried retrogame with no luck.. i followed the instructions as best i could and think i did everything to the letter but no luck, none of the buttons wired to the GPIO do anything.

i have just found another driver called mk arcade joystick

but i just dot understand the instructions... at all


can anyone give me an idiots guide to this working?

or link me to a retropie download with it already all installed?

please help me!

Just use Gpioneer.

Follow the simple instructions on that page, and it basically does it all for you.

I used adafruit keyboard press gpio driver called retrograme.

Gpioneer is the business. Quick tip: Run a keyboard through the OTG and run it from there. I couldn't get it to register keypresses while running it from SSH.
