Coin Inserter on GPIO-Pin
-
Hi all,
I build a small box with a photodiode that recognizes an interrupt when a coin falls inside the box.
I want to connect it to a GPIO-pin and configure it as the insert-coin-button.All iam looking for is a way to set this up in a config file, but I could not figure out where.
I am using libretro for the arcade games, where I want to use this feature.
Do I have to edit the retroarch.cfg? And how?It is important that I keep the feature of pressing Select and Start to exit games, because Select is the Default key for inserting a coin.
Any ideas.
Thank you vefy much.Christoph
