First off: I have patched up the adapter on a breadboard and the FFP works great.
As far as I know, the FFP is complete. Everything works. [...]
Oh that's amazing, I thought it wasn't implemented yet because of Grendel's first post in the other thread. Guess I should have read this whole thread before posting. I still have to try it out though as I have sold off my FFP's power supply a few years earlier in (what appears to be now) a not so smart move, thinking I would never use it again.
[...] I'm not sure what you mean when you say you "have an extra midi port available" [...]
Well what I meant was that I have a midi keyboard with a midi output on it (and a lot of patchcables to cut up). But gladly it seems I'll "just" have to write a standard FFB plugin for KSP.
Now I still have some questions about the firmware. Am I correct in thinking that the adaptffbjoy-r54.hex
is basically the same as the 3DPro32u4-10.hex
firmware but with FFB support and 4 extra trim pots/axes?
About the trimpots. Yes, they were intended (and used) for additional analog axis and primarily I myself put them since I wanted to have my rudder pedals, elevator trims and rudder trims in the same controller when playing my favorite combat flight sim IL-2. Anyone is free to use these additional axis for anything or just leave them unused. I have them connected to pedals and a couple of quality pots I have mechanically attached to a side of my Sidewinder so I can easily reach them with my fingers while playing. I was actually still missing a couple more of these analog axis for the wheel breaks of an airplane (like some commercial pedals have), but as the pedals I made for myself didn't have enough mechanical parts, the wheel break axis were still left out from the adapter project too. It is quite easy (for a programmer with basic AVR-skills) to have these additional axis. And I think there is still room for some additional buttons too if desired.
I would love to turn this adapter into a little control box with a small joystick for translation, some switches and a big abort button. So I'm rather interested in the additional buttons that can be added.
Futhermore I am having a little trouble with getting the extra axes to work with a logitech pedal I have, but I'll try it with a normal 10k pot first before asking for help.
