acevo-sdk

acevo-sdk is a Python SDK for Assetto Corsa Evo log parsing and shared-memory telemetry.

It packages the reusable telemetry foundation extracted from SimLaps so other projects can build on ACE data without reimplementing log parsing, binary decoding, or shared-memory capture.

This is an independent community SDK. It is not official Kunos Simulazioni or Assetto Corsa software.

Install

pip install acevo-sdk

For local development from this repository:

python -m pip install -e ".[dev]"

What It Includes

• ACE log parsing for sessions, laps, sectors, validity, player identity, car, track, tyre compound, setup notes, and fuel signals.
• Live shared-memory capture for ACE physics, graphics, and static regions on Windows.
• Decoders for captured shared-memory bytes.
• Reusable dataclasses for laps, sessions, stints, frames, capture metadata, and shared session state.
• Track catalog helpers and bundled track catalog data.

What It Does Not Include

• SimLaps API submission.
• Discord notifications.
• Personal-best cache.
• Desktop UI.
• Signing, anti-cheat, or server security helpers.
• HTML telemetry reports, AI prompts, or the larger telemetry analyzer pipeline.

Those belong in downstream applications for now.

Use Cases

• Build lap-tracking apps like SimLaps that parse ACE logs, detect sessions, laps, sectors, validity, and send structured data to a custom backend.
• Capture live shared-memory telemetry for dashboards, overlays, stream widgets, engineering tools, or race-control utilities.
• Decode saved raw shared-memory dumps offline for reverse engineering, debugging, analysis notebooks, or regression tests.
• Build coaching tools that consume lap, sector, car, track, fuel, tyre, and telemetry signals, while keeping AI/report generation in the downstream app.
• Create personal data pipelines that export ACE session data to JSONL, SQLite, DuckDB, Parquet, spreadsheets, or analytics services.
• Build test fixtures and validation tools for ACE telemetry integrations without each project reimplementing log parsing and binary decoding.
• Prototype future setup/tuning tools on top of stable decoded telemetry and catalog APIs.

Parse Logs

import asyncio
from acevo import LogParser


async def main():
    parser = LogParser()
    sessions = await parser.parse_file()
    for session in sessions:
        print(session.track, session.car, session.best_lap)


asyncio.run(main())

You can pass a specific log file or directory:

parser = LogParser(r"C:\Users\you\Saved Games\ACE\Logs")

Capture Shared Memory

Live shared-memory capture is Windows-only because ACE exposes telemetry through Win32 file mappings.

import asyncio
from acevo import TelemetryCapture


async def main():
    capture = TelemetryCapture(hz=20)
    await capture.start_capture()
    await asyncio.sleep(30)
    frames = await capture.stop_capture()
    print(f"captured {len(frames)} frames")


asyncio.run(main())

If your application already knows whether the game is running, you can inject a callback:

capture = TelemetryCapture(game_running_callback=lambda: True)

When no callback is provided, the SDK does not enforce game-process detection.

Decode Raw Bytes

from pathlib import Path
from acevo import decode_graphics, decode_static

graphics_bytes = bytes.fromhex(Path("graphics_frame.hex").read_text().strip())
static_bytes = bytes.fromhex(Path("static_frame.hex").read_text().strip())

graphics = decode_graphics(graphics_bytes)
static = decode_static(static_bytes)

print(graphics)
print(static)

Public API

Status

acevo-sdk is Alpha software. Version 0.1.0 is the first extracted SDK release, so public APIs may change while real downstream use cases settle.
