I made a SimHub plugin to control the PXN V12 Lite LED bar using game RPM telemetry
Hey everyone,
I’ve been messing around with the PXN V12 Lite wheel and wanted to make the built-in LED bar actually useful in games through SimHub.
After a bit of USB/HID packet digging, I managed to get the wheel’s LEDs working with live RPM telemetry. I turned it into a small SimHub plugin.
GitHub repo:
https://github.com/5nax/PXN-v12Lite-Led-Control---Simhub-Plugin
Current features:
- RPM-based LED bar
- Green/orange/red RPM zones
- Limiter flashing
- Custom limiter colour, including purple/custom RGB
- Adjustable limiter LED count
- Brightness control
- Reverse LED order
- RPM smoothing
- Fallback max RPM
- HID scan for VID/PID
- Idle modes, including individual LED control
- Settings panel inside SimHub
The limiter logic is set up as a hard override, so when the limiter hits, the normal RPM LEDs stop and only the limiter flash runs. That avoids the messy overlap where green/orange RPM LEDs keep showing under the flashing limiter.
Tested on my PXN V12 Lite:
VID: 0x11FF
PID: 0x1112
Packet header: 64 41 E0 02
Visible LEDs: 10
It is still early and unofficial, so other PXN firmware versions might behave slightly differently. I added a HID scan option so people can check their own wheel details.
Would love feedback from anyone else using a PXN V12 Lite with SimHub. If someone can test it on another unit, that would help heaps.
