Because I'm working on a project with electricians that already made a board that collects the buttons input and resend it to the Raspberry. That creates a layers between the buttons/joysticks and the mother board of the RPI3.
The problem is that the mapping made on the electricians's board is different that the one used by default on Recalbox.

We're running out of time and we can change de board. Is there a way to modify the default GPIO mapping to make it compatible with our mapping ? I hope you can help us !

@paradadf already tried it but it doesn't work... I created a very simple .lus file that show a square, zipped it and renamed it but it doesn't launch on my RPI3 running Recalbox...

Other suggestions?

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.

Hi everyone !

I'm currently trying to run a Lua file (a game small developed by a small team) on lutro which is in Recalbox (OS running on a raspberry pi3 on v18.07.13). After many tries, I and my group discovered that only .lutro files can be launched on lutro. However, I can't find any way to create a .lutro file or to convert a .lua file into a .lutro file. The final goal is to launch a game coded in lua on a raspberry pi3. What it does now: It runs .lutro games perfectly (the ones who already exists on internet), but it doesn't launch Lua files, it runs the game for 2 seconds and automatically exits the game (With nothing showing up on the screen).

I would need help very soon, my group's time is running out.

Thank you !

Hello everyone!

I and my group need to do a personalized GPIO mapping for the Recalbox OS (v18.07.13) running on our Raspberry Pi3.

Our plan is to plug to our raspberry pi3 : 2 joysticks and 10 buttons. Originally there's a standard GPIO mapping pre-configured by default in Recalbox, but when the project began we didn't know that and now we have a personalized GPIO mapping that we can't change. We need to change the Recalbox mapping to match with our project.

That's why we need to re-map the GPIO pins in a way that we can have 2 GPIO controllers

Could you help me please? Time is running out...
