How do I add Gran Turismo 7?

[Osaka78-on-GitHub]

Hi I'm searching for a way to run a motion rig that works on Gran Turismo 7 but with out Windows.

I'm a Linux user and have been testing what we have so far for to grab GT7 Telemetry for Motion Rigs on Ubuntu. It's a lot, mainly Python.

But I haven't found much to get the Telemetry into the motors without using a Windows PC.

I fired up Motion-Master and it loaded up great on Ubuntu. So that's a great sign.

I searched your code to see where the telemetry is connecting but I couldn't find it. I think it's in the Motion-Master/.git/objects/pack folder but not sure

How do I connect the GT7 Telemetry to Motion Master?

Thanks

Hey @Osaka78-on-GitHub , thank you for your interest in this project!

In most racing game you will be able to open a UDP port within the game's settings, unless it is open by default. In /main/packets.js is where I am actually parsing the UDP packet according to the FH5 UDP specification:

if (game === "FH5") {
rpm = Math.floor(Buffer.from(msg.slice(16, 20)).readFloatLE() * 100) / 100;
xAccel = Math.floor(Buffer.from(msg.slice(20, 24)).readFloatLE() * 100) / 100;
yAccel = Math.floor(Buffer.from(msg.slice(24, 28)).readFloatLE() * 100) / 100;
zAccel = Math.floor(Buffer.from(msg.slice(28, 32)).readFloatLE() * 100) / 100;
yaw = Math.floor(Buffer.from(msg.slice(32 + 24, 36 + 24)).readFloatLE() * 10000) / 100;
pitch = Math.floor(Buffer.from(msg.slice(36 + 24, 40 + 24)).readFloatLE() * 10000) / 100;
roll = Math.floor(Buffer.from(msg.slice(40 + 24, 44 + 24)).readFloatLE() * 10000) / 100;
gear = Buffer.from(msg.slice(319, 320)).readUInt8();
throttle = Buffer.from(msg.slice(315, 316)).readUInt8();
brake = Buffer.from(msg.slice(316, 317)).readUInt8();
maxRPM = Math.floor(Buffer.from(msg.slice(8, 12)).readFloatLE() * 100) / 100;
}

The Node.js backend of this project will listen for UDP packets on the port specified on the input page, so that should match the GT7 UDP output port.

Adding support for GT7 would be as easy as doing some research to figure out how the UDP packet is structured to extract the data from it. If you figure it out and would like to make a pull request I would gladly merge!

Ok it's beyond me. I don't know where to start to change Python to Java. Thanks anyway. This looks promising though. Did you ever find out if there's any Johnny Five motor control boards that can control big motors that can lift 100kg? I looked and looked but Johnny 5 seems like tiny motors only
