acctelemetry-go

Simple Go library to read Assetto Corsa Competizione telemetry

Runs only on Windows!

How to use

ACC must be running. Otherwise, telemetry.Connect() will fail with an error.

Methods StaticPointer(), PhysicsPointer() and GraphicsPointer() returns pointer to shared memory, so data will change over time. It's up to client code to create snapshot of the data if they wish so.

RealtimeCarUpdate() is read from UDP broadcast and it returns instance of latest RealtimeCarUpdate state.

Example:

see examples/main.go

Configs:

see telemetry_config.go
