Buttons not detected as gamepad

[bjornthor21]

Hello I am trying to setup a little controller with 8 buttons, 4 for the dpad and the other 4 are (Start, Select, A, B), keep in mind this is a homebrew controller, i managed to go through the config and every button was detected and saved but when i boot up and i am asked to setup a gamepad it says "no gamepads detected" and it does not respond to anything from the buttons.

thanks for your software it is amazing

my setup:

Raspberry pi model 3B+ Retropie 4.8 running on sd card pins: 29, 31, 33, 35, 37, 40, 38, 36 (every pin from 1 to 28 is occupied by agn lcd screen)

Thanks again for your software. i really respect every single one that releases software open source! :), let me know if you have any questions

ok, couple of things to check first

1) make sure you start gpionext after config by running gpionext start 2) you can use jstest to test the controller by typing gpionext test 1 (if you have multiple joysticks you can use 1,2,3,4 to test each)

If both of those are working, then its most likely a problem with a retropie config. In which case I would suggest trying to set up your controller as a gpionext keyboard and see if that works.

hello and thanks for the quick reply i did what you suggested but no luck. i reinstalled gpionext and went through the config again with with no success. i dont know if it is relevant but i run the config program with this command which you supplied sometime ago: sudo python3 /home/pi/GPIOnext/config_manager.py --pins 29,31,33,35,37,40,38,36

i tried the "gpionext test 1" but i get this message:

cat: '/sys/devices/virtual/input/input*/name': No such file or directory Could not find GPIOnext Joypad 1 in virtual devices

i then tried to setup the controller as a keyboard which did not seem to work

if it makes a diffrence i am connected to the pi using ssh

I just realized, did you set the pins flag? gpionext set pins 29,31,33,35,36,37,38,40

If not, it will error out when it gets to a pin that is already being used by something else.

If it's not working after setting the pins, then it's probably hitting an error somewhere. Stop gpionext by running:

'gpionext stop'

Then run it manually

'sudo python3 /home/pi/GPIOnext/gpionext.py --pins 29,31,33,35,37,40,38,36'

That should let you easily see what error you are getting

Hey that's great! I'm glad it's working for you! I really appreciate the enthusiasm for something I've made.

I don't currently take donations, but given what's going on in the world I think it would be great if you made a donation to Refugees International or YOUR favorite charity!
