    Hello everyone,
    I'm new here and would like to introduce myself in a few words:
    My name is Jürg, I'm 20 years old and from Switzerland (sorry for my English, I try my best). I recently finished my education as a software developer. My favourite programming languages are C and C#. I love to combine Hardware with High Level Tier Software in my spare time.

    It all started when I bought my G27 racing wheel from Logitech. Soon I had the idea to build my own simulator (starting with single peripherals). I was really lucky one day as I found an old Speedometer of a Seat Ibiza (97) that was quite cheap. I connected it to my Arduino Uno and now I'm able to control nearly every element (RPM, speed, fuel, warning lights, MDA display) of it. The plan is to send game data over serial port to my arduino, but the acquiring of data out of a game (especially DiRT 3) seems to be the hardest part of the project. I searched for informations for a couple of hours now, without any success. The only thing that worked was receiving motion data from DiRT 3 with a UDP client I wrote with C#, but I'm interessted in the gauge data. I would be so happy if someone could tell my how I get the data with C# or any other tips (Addresses/Offsets in Memory for example).

    Thx in advance for your answers!

    Hi

    Its possible to use the dbox driver which is bundled with codemasters/dirt3 on the PC
    to access some of the telemetry via a network socket. I dont know the structure of the
    protocol but you could use a protocol analyser to figure it out.

    Here's the process for activating the socket on the PC.

    Open hardware_settings_config.xml which is located in your savegame folder of the game.
    C:\Users\yourusername\Documents\My Games\DiRT3\hardwaresettings

    Open this file and look for a line that begins with:
    <motion enabled
    Replace this line with:
    <motion enabled=true ip=127.0.0.1 port=30500 delay=1 extradata=1 />

    Cheers

    My Motion Simulator:
    2DOF, 3DOF, Arduino, Motion platform

    if (extradata == 1)
    {
    //parse more packet data
    }


    i want to know packet structure and information.
    i can't find it.. T_T
