leds4sim

This is a quite simple daemon for sending car sim telemetry into a MOZA device (for now, TSW wheel specifically). Existing software like monocoque, while being great overall, is not quite fit for use with "civilian", not racing, cars. So this piece takes telemetry info from a memory-mapped file containing info from SDK (in my case, SCS Truck sim SDK) and sends it to the wheel via its interface directly, not using a midlayer like simapi. (But, as the telemetry info is specified in the config file by its memory-mapped locaions, this software can be used with simapi too.)

Disclaimer: it's still pretty raw work-in-progress, so expect changes in logic and configuration.

Using release binaries

The .deb package is provided for deb-based distros. Check its dependencies.

There's also a statically build executable, for those who want to test it without installation, or just prefer it this way. Don't forget to unxz it and make it executable (chmod +x).

Building from source

Build dependencies

• libserial
• libconfig++
• libxdg-basedir

Building

cmake -B build
cd build
make

Configuration

The configuration file is mandatory and needs to be either in the current directory (takes priority), or somewhere in XDG-compliant location (standard priorities apply), usually ~/.config/leds4sim.conf. See libconfig documentation for general structure of the configuration file, and comments in conf/leds4sim.conf.
