OpenRMS is an open platform for Slot car Race Management written in Go.

The motivation for starting this project is, my experience getting into slot cars, and the software tooling around the hobby is for the most part closed source, and in many cases unmaintained, platform dependent.

The idea is to create an open source race management system capable of supporting multiple vendors such as Scalextric, Carrera or Oxigen.

Other than supporting as many vendors as possible, The community should be extend OpenRMS with the features need, it could be better support for Arduino, it could be having yellow flags light up around the track if a car has crash.

Last it must be platform independent, the goal is to be able to run it on a Raspberry Pi, eliminating the high entry price of a computer with a Windows license. The goal is to release a version that will work on both Mac OS, Linux and Windows

I'm no expert in frontend development, I would like to ask the community for any help with the frontend part of this project. Also if you have any comments, suggestions on new features or changes or you want to help extend openrms with support for other systems then Oxigen please let me know.

To get it running start by downloading the version that matches your platform. Windows, Linux amd64 & arm (RapberryPi) is supported.

See detailed guide for windows here

Linux does not require any dependencies, all you need to do is identify your Oxigen dongle device name. to find the oxigen device simply plugin the dongle and execute dmesg in a terminal, note: on some systems this requires elevated privileges, if that is the case run sudo dmesg instead. look for the following 4 log lines:

[   80.311293] usb 1-1: new full-speed USB device number 7 using xhci_hcd
[   80.461950] usb 1-1: New USB device found, idVendor=1fee, idProduct=0002, bcdDevice=10.00
[   80.461955] usb 1-1: New USB device strings: Mfr=0, Product=0, SerialNumber=0
[   80.463802] cdc_acm 1-1:1.0: ttyACM0: USB ACM device

the last line in the output example shows the device name ttyACM0. write the name down and edit the config.yaml file, find the implement section and change the port to /dev/<devicename>.

implement:
  plugin: oxigen
  oxigen:
    port: /dev/ttyACM0

now go to running OpenRMS.

To build run make openrms

When you have openrms build run ./openrms. if you have want to set a path for the configuration file set the -config flag: ./openrms -config <file>

Configuration is done via the config.yaml file. edit the file with the settings that matches your setup.

OpenRMS is build in a modular way, it's build around 3 different plugin types:

• Implement
• Rule
• Telemetry

Messages are passed around each component using either events coming from the implement, and commands sent to the implement.

Rules are then applied to each event, and each change made by a rule is sent to the implement via a command. A rule can subscribe to individual changes, and make changes to the state.

The full sequence diagram can be seen below:

The implement is the connector, this plugin type provides connectivity between your hardware for example the Oxigen Dongle.

The rule is the definition of rules which are in effect during a race. for example fuel simulation

The pit stop process is a little different from seen else where, for example while the car is being "worked on" the car is disabled an unable to move. The process does not start immediately, and the process can only be started once each time the car enters the pit lane. Therefore, the pit stop must be confirmed by not pressing the power lever and either pressing the track call/brake button for at least 1 second, or simply just wait for 5 seconds.

Optional plugin type which allows all metric collected to be shipped of to a database like InfluxDB

Please note we have a code of conduct, please follow it in all your interactions with the project.

1. Ensure any install or build dependencies are removed before the end of the layer when doing a build.
2. Update the README.md with details of changes to the interface, this includes new environment variables, exposed ports, useful file locations and container parameters.
3. Increase the version numbers in any examples files and the README.md to the new version that this Pull Request would represent. The versioning scheme we use is SemVer.
4. You may merge the Pull Request in once you have the sign-off of two other developers, or if you do not have permission to do that, you may request the second reviewer to merge it for you.
