Fanatec Static Paddles (DIY)

[capitan_penurias]

Hello !

I build a complete static paddles for Fanatec wheelbases, including the electronics needed to connect the paddles to the SHIFTER2 port. The main advantage of this project is that you can design your own sequential shifter and plug it into the base directly, avoiding using a microcontroller (and a usb port). All the parts are 3D printed.

Thanks! Definitely please pit it together with the rest documentation, will save me some troubles to create GIT branches

It will take me some time to actually make it as just now ordered parts, but theoretically looks good.

Cheers!

Thanks!

It's me again. I believe I am done with coding. I guess it should work if I have not mistaken something generally, double checked pinouts - think it is the correct ones. X/Y values are reverse to what somebody normally expect, but did not wanted to redraw everything.

Code is compiling well, I will have to learn tomorrow how to run it in MPLAB simulator to see if all is well.

Here is what I have for now, most probably this is it:

Edit: I really suck at writing code, had to redo most of it. Ran it on the MPLAB simulator, now seems to work fine.

Any chance you’d assemble a kit for those of us without access to a printer/materials?

Thanks

The H-pattern Fanatec shifter is completed and works like a charm! Pretty satisfied with it.

Here you can see domo of the adapter:

And complete documentation is here:

https://www.diy-sim.com/guides/projects/item/universal-fanatec-shifter-interface

I saw on GitHub somebody is making progress on interfacing pedals - this would be something interesting to look into, handbrake compatibility is also quite tempting as well.
