Bonjour,

Le GPIO sur le PI5 n'est pas opérationnel, pour y brancher des boutons entre autres.
On y travaille pour une prise en charge dans une future version si une solution est trouvée.

En contournement, l'utilisation d'un encodeur USB est préconisée. Je laisse répondre les spécialistes pour l'installation/configuration, n'en possédant pas.

Welp, I don't know how I did it, but I managed to fix the issue. it really was the recalbox-user-config.txt. I made sure to delete all my userscripts, pasted in this code in the user config: dtoverlay=gpio-fan,gpiopin=14,temp=60000 and connected my resistor wire to the corresponding GPIO pin and now it works exactly how I want.

I started noticing the fan was actually starting and stopping while the box was on after moving everything to a new SD card. I don't think it was the card that fixed it as I copied everything in both the recalbox and share drives to the new image, overwriting everything with my configs. The only difference is I removed the bash and python scripts I was experimenting with in the userscripts folder. The user-config still had the previous line of code and actually started working.

I still had one problem as I was still using GPIO 3 instead of 14, and the fan would stay on if I quit recalbox through the menu instead of a hard power down by holding down the button. Switching to GPIO 14 like I originally wanted and updating the code to match the pin fixed this, thankfully. Now I have a properly functioning mini fan that came with the case.

Tl;Dr;

If you buy a Geekpi case for Raspberry Pi 5, buy a EZ fan2 for it with some extra wires. Install the 5v and ground wires into pins 4 and 6 like the Geekpi instructions say, and add your new resistor wire to pin 8 (GPIO 14).

Set up your recalbox as recommended, doing the first time boot and setup so it creates the needed files.

Open up your recalbox-user-config.txt located in the root of the RECALBOX drive either on your computer or via a network.

Paste in dtoverlay=gpio-fan,gpiopin=14,temp=60000 in a free line.

#Add a comment line above the code like this to write down it's the fan control code if you'd like

reboot

And that should work. I will experiment to see if why it didn't work for me before might have been because I wrote 55000 for the temp and that was too low or not, but I'm satisfied with 60 degrees as a trigger.

I will also quickly mention that the EZ fan2 does fit in the rather compact case. Just tuck it under the board with the wires in an "S" shape.

I still think it would be nice if there could be a GPIO fan control menu in emulationstation like Raspberry Pi OS has, but I managed to work around it.

Thanks for listening and hope this helps someone in the future.

@Khelann49 si c'est le cas c'est un peu embêtant , ne pas pouvoir avoir accès a l'usb pour un clavier ou une cléf est très handicapant . J’espère que ce n'est juste qu'un problème de carte sd

I have the same problem. I had a Raspberry Pi 3 that worked with my normal GPIO arcade controller, now I switched to a Raspberry Pi 5 and the controller doesn't work

@Nazgulh Il les détectais avant et là il met manquant, pourtant j'ai bien pris le bon pack placé au bon endroit.
De plus, la config manette est à refaire à chaque démarrage ... bizarre

(le WIFI ne marche tjrs pas non plus mais j'ai branché réseau pour que les drivers du Xi-mo se donwload au démarrage/

@Pitch64 👍

Bon, après de multiples essais, j'ai trouvé une config qui marche ! 😊
Avec ce P2K :
0:a = space ;; fire
0:r1 = F0 ;; pause
0:start = F1 ;; Abandon
0:l1 = F2 ;; Son
0:y = 1 ;; 1
0:x = 2 ;; 2
0:select = enter ;; enter
1:a = space ;; fire
1:j1left = H ;; left
1:j1right = J ;; right
1:j1up = Q ;; up
1:j1down = A ;; down

Et avec également la config Retroarch suivante (Menu rapide/touches/touches du port 1), sur le port 1 mais ça active le joystick du 2ème joueur... :

C'est uniquement les GPIO controller analogiques que j'ai renseigné (avec up, down, left, right)
Il faut également pour Menu rapide/touches/touches du port 2, enlever "A" dans GPIO controller 2 Bouton A.
Et ça marche ! Trop bien.
