I’ve decided to upgrade my pit and get a Force sensitive mod for my stick. I’m currently using a stock Warthog, and I love it. the grip is fantastic. However, there is only one mod for it, which is the very expensive FSSB-R3 made by RealSimulators. The product seems to be a very good piece of engineering, and is a drop in replacement for the WH, slap the grip on the base and you are done. However, mounting in in a proper stick base is somewhat more problematic. The other Force-sensing mod is the FCC3 by ViperCore.nl it is somewhat cheaper, community proven for years. However, it has a major drawback, it requires the Cougar PCB to work. I have a cougar, but I refuse to use it 🙂 (see my TQS controller series).
But a lack of controller never stopped me 🙂 So I opted for the FCC3 and started to dig into my Cougar to understand what will be required.
In this post I’ll dive into the grip wiring and bit ordering, and all the other fun things I had to dig into a whole bunch of documents to find.
I have been quite for too long 🙂 with the release of BMS4.33 followed by the Israeli Theater, I’ve had not much time to update the blog. However the Pit has been going places 🙂
first of all, I’ve replaced by 27″ 1440p display with a 40″ 4k computer monitor. I’m still tweaking graphics options, to get the performance to where I want it.. but it looks good!
I’ve also finally re-wired my pit, and installed the ICP, making things even better 🙂
in addition, I’ve been tweaking with the TQS adapter, trying to add a curve to the microstick, allowing better finetuned control in game.
I’ve also published on github a little GUI wrapper for avrdude that allows a quick upload of images to ATMEGA 32u4 chips, I use it to quickly upload new FW to the throttle and ICP, but I assume others might find it usefull for other things as well.
Everything is already available in the download page.
You can browse the code and download all the stuff you need (including a pre-compiled Hex, ready to be uploaded to your device – incl. a simple script to help with it for those of you who only want it to work :))
Here is a small clip showing how it looks in windows.
Now let’s dig into some technical stuff (only if you want to) 🙂
Following input and assistance from “Moon” and “AiRdAncE” the VP community, I’ve been pointed to the real FFI font, “MilSpec 35588“.
I’ve adjusted size and removed unneeded chars to create a new custom FFI font pretty much in the correct size to match a real face plate. Once I have one fabricated, I’ll adjust the font some more – but for now that is good enough IMHO
As always, the code is available on github.

I’ve been Working on some way to streamline performance as much as I could. The biggest performance limiter, is the drawing of the big screens (DED/PFD),
One of the tricks I’ve thought might help was to switch the display from 2 bit color mode to 1 bit (4 shades of “grayscale” to only “black and white”) theoretically – a 100% boost, it practice I have discovered I had a bug in the code all along. Apparently U8Glib has a switch to handle displays bigger then 240pixels, I’ve known about it but as long as I’ve been using the grayscale mode, I’ve been unaware of it (because the part that didn’t work was black). once I’ve switched to BW mode – it lit up casing stripes on the screen.
To fix this, and simply basic installation, I thought about including the entire U8Glib library, with the required change in the folder. Unfortunatly, the Arduino IDE does not allow this, So I’ll be including a ZIP file with the modified library for easy import into the IDE.
I’ve also found out that my plan to flip the DED display (to allow better weight distribution in the case) is a very bad idea as putting in “rotate 180” on the screen almost halfs the FPS.
I’ll be working on this some more till the PCBs arrive – but I think this is pretty much the limit as far as my ability to optimize the code to improve refresh rate.
