Other pin / button configuration. recompile? #43

Please fill the following form : What happened

Wanted to use this recalbox i2c driver to work with my kitsch bent i2c dmg button pcb. (http://store.kitsch-bent.com/product/expanded-dmg-button-pcb-i2c-version)

What should have happened Thought the configuration would work like expacted, but checked the pinout and found out, that this driver is using an another pinout configuration.

This is the pinout, used by the kitsch bent i2c controller: pinout:

GPA2 — B GPA3 — A GPA4 — R2 GPA5 — R1 GPA6 — X GPA7 — Y GPB0 — UP GPB1 — L1 GPB2 — L2 GPB3 — LEFT GPB4 — RIGHT GPB5 — DOWN GPB6 — SELECT GPB7 — START

this driver is running with other pinouts, which concludes in wrong / not working buttons.

Is it possible to recompile the driver, for use with the pinout above?

tried it by myself, but couldnt make it to a functional version.

Hey tarifari, i have the same problem but you are able to change the pin in this driver. See https://github.com/recalbox/mk_arcade_joystick_rpi/blob/master/mk_arcade_joystick_rpi.c#L186 and https://github.com/recalbox/mk_arcade_joystick_rpi/blob/master/mk_arcade_joystick_rpi.c#L189

after edit this file you will need to recompile...

But i´ve got another problem: my start button is not working (GPB 7) - all other buttons are working...
