Simtezilo is an application for processesing live Gran Turismo 7 telemetry data and transforming it into haptic feedback for tactile transducers (aka bass shakers), voice-based race notifications via Discord, and visual dashboards for web browsers and Raspberry Pi displays.

Background

Simtezilo arose from a fairly simple idea of getting some audio feedback about race state so that on-screen overlays could be disabled when racing in VR (Virtual Reality). During early experimentation the idea quickly evolved into a solution for producing full haptic feedback through tactile transducers, with support for running on a small Raspberry Pi to avoid the need for a bulky desktop or laptop machine that other existing solutions require.

The gt-telemetry library was the first component to be built, providing an easy way to read telemetry from the game using Golang. This library is still a core part of Simtezilo.

Today Simtezilo outputs haptic feedback through audio devices, voice notifications through Discord, and provides both a web-based dashboard and an SPI LCD interface for Raspberry Pi hardware.

Output interfaces:

• Haptics — Chassis bumps and impacts, engine geometry specific vibration characteristics, transmission gear changes
• Pit Radio — Discord based voice notifications for race laps, lap times, progress as well as fuel and tyre advice.
• Web UI — Browser-based configuration and telemetry
• SBC Hardware — LCD GUI and button support for on-device configuration and race data display

Supported platforms:

• Raspberry Pi (primary target)
• Linux
• MacOS
• Windows

Installation and documentation

Visit the Simtezilo website for all installation and configuration documentation.

Development

See development.md

Quick-start

Ensure the install Go version matches or exceeds the value in go.mod.

1. Setup config to replay a demo recording

   sed 's/"source":.*/"source": "file:\/\/.\/data\/replays\/demo.gtz"/' support/simtezilo.conf > simtezilo.conf

2. Start Simtezilo

   make run

The haptic signal should now be output through the currently enabled audio output device.
