LOGITECH DRIVING FORCE GT CALIBRATION DRIVER

The default configuration files for the Momo Racing, the DFGT and the G27 contain these new parameters. To fix this, I added joystick correction parameters to the configuration files, that can be configured in a new РІР‚СљJoystick correctionsРІР‚Сњ panel of the existing РІР‚СљOverallРІР‚Сњ panel (in gimx-config). The existing GIMX axis translation parameters (dead zone, sensitivity, acceleration) do not allow to translate the pedal axes back to an absolute range. with 255 the rest value) to a relative range ( with 32767 the rest value). When using Logitech wheels in both GNU/Linux and Windows, the pedals axes are translated by the operating system from an absolute range (e.g. This removes the need for a calibration step! I realized that modifying all the Joystick and Gamepad usages to the Multiaxis Controller usage in the HID report descriptor makes the kernel not to apply undesired deadzones.

One issue that arises when using UHID is that the generic HID input driver applies deadzones to all axes, which is a questionable choiceРІР‚В¦ Anyway, this complicates the setup as this requires to calibrate the wheel. Fortunately, the UHID driver allows to pipe the HID input reports from libusb (userspace) to the HID input driver (kernelspace). On GNU/Linux, it uses the libusb, which sadly canРІР‚в„ўt be used at the same time as the HID input driver. In a previous post I explained that I built a cross-platform (GNU/Linux and Windows) HID communication layer with asynchronous read and write capabilities.
