I’m trying to hook up an old G27 brake pedal using the X11-upper port. I think I have understood the wiring diagrams correctly, though I’m not having any luck getting it configured. The image below shows how I have linked up the potentiometer to the cable.
When I go to the configure analog inputs tab in the Simucube software, and enable the pedal, the raw value hovers around 14-17. But when I compress the pedal, the raw value increases but is not stable. It will spike everywhere between the compressed and uncompressed value. I have tried ground the +5v tab of the potentiometer to the metal casing of the pedal, and grounding the pedal to the simucube base/electronics unit. But none of these seem to make any difference. Could anyone guide me as to what I’m doing wrong?
