# Third-party and separate-license notices OpenHaldex is a mixed-license project. This file records separate copyright, license, and provenance boundaries; it does not place all listed material under one license. ## SignalScope / Chris SignalScope is Chris / Bored Systems' independent, reusable CAN framework. The generic engine is licensed under the MIT License in `LICENSES/SIGNALSCOPE-MIT.txt`. The current OpenHaldex application uses SignalScope for CAN ingress, DBC decode, declarative mutation, replay, caching, recording, and forwarding. ## OpenHaldex / A Banging Donk - Project: OpenHaldexT4 - Author: A Banging Donk - Repository: A Banging Donk originated the public OpenHaldex platform and foundational Gen 1 control work. The current public repository does not contain a license file. This project preserves attribution but does not invent a license on the author's behalf. Any direct reuse must rely on permission actually granted by the author or on a separately licensed downstream expression. ## Required OpenHaldex-C6 MIT notice - Project: OpenHaldex-C6 - Copyright: 2026 Forbes Automotive - Repository: - License: MIT; full notice in `LICENSES/OPENHALDEX-C6-MIT.txt` During development, portions of the current Gen 5 compatibility package were translated with reference to this MIT-licensed source. The copyright and license text are therefore retained with distributed legal notices for that package until its remaining compatibility expressions are independently re-derived and verified against primary DBC/capture evidence. This is a license-compliance notice, not product credit or endorsement. It does not assert ownership of Volkswagen Group CAN facts, message identifiers, signal mappings, captured observations, Chris's independent vehicle validation, or the current SignalScope/OpenHaldex SS implementation. Gen 2 and Gen 4 compatibility in this edition were independently validated against Bored Systems' DBC library and vehicle evidence and are not attributed to this source. The current diagnostic pressure calibration and normalized output table are likewise part of the OpenHaldex SS diagnostic/calibration implementation, not credited to this source. ## Earlier OpenHaldex-S3 / Chris - Project: OpenHaldex-S3 - Author: Chris / SpringfieldVW - Repository: - License of published snapshots: MIT; full notice in `LICENSES/OPENHALDEX-S3-MIT.txt` Previously published S3 source and S3-authored material already received under MIT remain under that grant. The current proprietary application license does not revoke rights in those earlier copies. ## Velonic Admin UI / Techzaa The OpenHaldex firmware interface in `data/` includes selected and customized assets derived from the Velonic Admin template by Techzaa, licensed through ThemeForest for this end product. Velonic-derived assets remain subject to the purchased ThemeForest license. They are not licensed under MIT or the OpenHaldex personal binary grant and may not be extracted or redistributed as a standalone template or stock asset. The full Velonic package, PHP demos, documentation, and unused components are not part of this project. ## Firmware and browser dependencies The build and UI include separately licensed libraries and assets, including Arduino-ESP32/ESP-IDF components, ArduinoJson, autowp-mcp2515, Bootstrap, Chart.js, fonts, and icon sets. Copyright and license notices embedded in those packages continue to apply. A proprietary binary release must preserve all required notices and satisfy the applicable object-code/relinking obligations, including any LGPL-covered Arduino-ESP32 components. This notice is not a substitute for the release's complete dependency inventory. ## DBC and OEM diagnostic data `protected-sources/dbc/vw_pq35_46_acan_v5.20.6.dbc` was generated from a Volkswagen K-Matrix workbook. The other raw DBC definitions under `protected-sources/dbc/` and the normalized diagnostic library at `protected-sources/diag/diagnostic-library.json.gz` are likewise build-only sources. The diagnostic library and generated firmware projections were built from ODIS/MCD/ASAM project resources and captured diagnostic evidence. Those facts establish technical provenance, not redistribution permission. The raw DBC and diagnostic sources are not copied into the LittleFS `data/` tree. The production build transforms them into packed DBC databases and bounded diagnostic query records inside an authenticated firmware-embedded asset pack. This packaging boundary does not create or expand redistribution rights in the underlying definitions. The project license does not relicense Volkswagen, Audi, ODIS, ASAM, or other OEM-derived definitions. Their distribution rights must be reviewed before a public firmware/filesystem package is published. Keeping the application source private does not by itself grant rights to distribute embedded data. ## Trademarks and affiliation Volkswagen, Audi, Haldex, ODIS, VCDS, LILYGO, Velonic, Techzaa, and other names belong to their respective owners. Names are used for compatibility, provenance, or identification. OpenHaldex is not sponsored by or affiliated with those parties.
