GPIO work in retropie but not in retroarch #28

jefflequeux commented 8 years ago

I use GPIO with this config:

{  22,     KEY_LEFT     }, // Joystick (4 pins)
{  23,     KEY_RIGHT    },
{  17,     KEY_UP       },
{  27,     KEY_DOWN     },
{  24,     KEY_LEFTCTRL }, // A/Fire/jump/primary/RED
{  10,     KEY_LEFTALT  }, // B/Bomb/secondary/YELLOW
{   9,     KEY_Z        }, // X/BLUE
{  25,     KEY_X        }, // Y/GREEN
{  18,     KEY_SPACE    }, // Select
{   4,     KEY_ENTER    }, // Start
{  11,     KEY_A        }, // L Shoulder
{   8,     KEY_S        }, // R Shoulder
{  13,     KEY_1        }, // PiTFT Button 2
{  19,     KEY_2        }, // PiTFT Button 3
{  26,     KEY_3        }, // PiTFT Button 4

It works great on retropie interface but not in game, retroarch doesn't recognize this GPIO, doesn't know why.

Maybe this issue is somehow related to this issue?

But in my case, I can play all the games in all the emulators except for the one in the my issue.

Please see the README for this repository for directions on setting up a UDEV rule; this should make retroarch recognize these inputs. You may need to further edit /opt/retropie/configs/all/retroarch.cfg to match the keys you've set up (the config isn't carried over from emulationstation for some reason).
