GPIO input for joysticks - Retrogame or GPIOnext
« on: January 03, 2019, 04:55:30 pm »
Does anyone here use the GPIO pins for input? I used them on a box controller I made and I am thinking of using them again on my next bartop. On my first one, I used retrogame but I have recently figured out GPIOnext. One of the things I found was to turn off the hot key delay to help lag.
Code: [Select]
gpionext set combo_delay 0
Does anyone use either? Do you notice a lag at all? I did not really notice any on my box controller.

The thing I like about those options is the fact that I can set the controllers as keyboard and then when you plug in a USB controller, you can use either for player one and two or you can make the plugged in controllers be player 3 and 4 instead for 4 player games. Just wondering if anyone else is going this route.

Works great for me.  No problems at all really.  Just a bit more extra work especially with the Pi Zero.  Cuts down on cost.
If I had only one wish, it would be for three more wishes.
