Hi, simracer fans
I just wanted to show you my last project.
After seeing the Steph Bord and V8Ben videos I wanted an FFB Happ steering wheel too !
But, instead of hacking a logitech board, I built my own FFB controller:
It's based on a Blueboard LPC1768H (I have also a version for LPCXPRESSO), 34$.
The main specs are:
- 1 kHz refresh rate output signal (ie: for AMC)
- 1 kHz refresh rate for USB data coming from game (even if most games actually update the data only 60-100 times per sec.)
- incremental rotary encoder for the steering wheel position (I'm using a 2048CPR, 8192 position per rotation, on direct drive)
- compatible with G25 pedals (and shifter soon)
- configuration via OLED display (soon)
- FFB monitoring, to avoid clipping (currently via serial port, and on OLED soon)
- no need to any driver
To drive the motor, I'm currently using an AMC servo drive, but I will build my own motor controller once the firmware is finished (for brushed and brushless motors).
I also removed the mechanical stop of the steering wheel, since it's managed with the motor (the steering angle is configurable).
This setup is more strong and fun than my G25 (I rediscover rFactor that I disliked before).
I can have strong FFB effects without clipping.
I think to provide a firmware soon (maybe for few bucks or donation).
