Custom GPIO pin config

[malkie]

Hi everyone, Im new to retrobox, i was looking for an alternative to retropie and this looks like a far better os! I have a pi zero with a controller already soldered to the gpio so i want to have a custom pin config. I looked at the mk_arcade_joystick_rpi notes on https://github.com/Pinuct/mk_arcade_joystick_rpi and it says you can do this by runnning the following command: modprobe mk_arcade_joystick_rpi map=5 gpio=Y-,Y+,X-,X+,start,select,a,b,tr,y,x,tl (swapping these out for your pins) I tried putting this in the recalbox.conf file first with the following and the system fails to boot: # ------------ D3 - GPIO Controllers ------------ # ## GPIO Controllers ## enable controllers on GPIO with mk_arcarde_joystick_rpi (0,1) controllers.gpio.enabled=0 ## mk_gpio arguments, map=1 for one controller, map=1,2 for 2 (map=1,map=1,2) controllers.gpio.args=map=5 gpio=3,2,4,17,10,9,27,22,-1,-1,-1,-1 I also tried every possible combination of the above before i noticed the following in the log file: [       10.87] : loading module mk_arcade_joystick_rpi args = map=5 so it looks like the extra arg is not getting through for some reason. I tried dissabling it in the config then manually running the following from ssh and this worked for map=1 but not for map=5 gpio=3,2,4,17,10,9,27,22,-1,-1,-1,-1 modprobe mk_arcade_joystick_rpi map=5 gpio=3,2,4,17,10,9,27,22,-1,-1,-1,-1 If anyone can help that would be ace, otherwise i have a painfull night of re-wiring ahead of me Thanks Malkie

ok, i just noticed that this code was written 19 days ago (10 days after 4.0.0-beta3 came out lol) so the reason it wasn't working is because i have the wrong version of mk_arcade_joystick_rpi installed i have read the instructions on how to install the latest version and they don't work on my recalbox install, i have some linux knowledge, mostly ubuntu for websites and raspbian for fun so please go easy on me: -firstly i am ssh as root but can't change anything on the drive becuase its read only? -secondly the instructions keep using commands that dont exist e.g. sudo and dkms? -thirdly all the repo links are out of date and point to an old location, i fixed this but it makes me feel that the instructions might be out of date? sorry for all the questions thanks adam

Hello,

I'm trying to remap GPIO pin configuration on my Raspberry Pi3 for my project.
I have made a personalized GPIO mapping that I can't change so I have to make Recalbox compatible with it.

It looks like you've already made it so maybe you can help me. I really need you help because I'm working with school team (I'm their teacher) and we're running out of time...

I hope you can help us !

Thank you.
