+# HOW-TO_REVERSE – Praxisleitfaden fürs CAN-Reverse-Engineering
+
+Dieses How-To ist dein Werkzeugkasten, um aus nackten Frames echte Signale zu destillieren. Es ist kein Orakel, sondern ein **Experimentier-Protokoll**: miss, verifiziere, falsifiziere. Nutze es zusammen mit der GUI/CLI (Splitter, Explorer, Batch-Analyzer, Range-/Unsupervised-Fit).
+
+---
+
+## 0) Vorbereitungen (Daten sammeln wie ein Ingenieur)
+- **Zustände trennen**: *Zündung an*, *Motor aus*, *Motor an Leerlauf*, *Schieben*, *aufgebockt Hinterrad drehen*, *kurze Fahrt*.
+- **Aktoren toggeln**: Blinker, Bremse, Licht, Lüfter → generiere Ground-Truth für Bits/Flags.
+- **Nur RX** analysieren, wenn deine Hardware parallel TX sendet (Störmuster vermeiden).
+
+---
+
+## 1) Frame- & ID-Ebene zuerst
+- **Repetition Rate (Hz)**: Zyklische Sensor-IDs senden stabil.
+  - *Daumenwerte*: WheelSpeed 20–100 Hz, RPM 10–50 Hz, TPS/APS 20–100 Hz, Lenkwinkel 50–100 Hz, Temperaturen 1–10 Hz.
+- **Jitter** der Periodizität: Streuung der Inter-Arrival-Times. Niedrig = sauberer Zyklus.
+- **DLC-Stabilität**: schwankende Payload-Länge → ggf. ISO-TP / Multiplex.
+- **Change-Density**: Anteil Frames mit Payload-Änderung. Zu hoch → Counter/Checksumme, zu niedrig → Status/Träge.
+
+---
+
+## 2) Byte/Bit-Signaturen
+- **Bit-Flip-Rate** pro Bit: ~50% → Flag/Event; sehr regelmäßig → Pattern/Timer.
+- **Rolling Counter**: 4/8-bit Sequenzen (0..15/255), oft konstant steigend.
+- **Checksumme**: Byte hängt deterministisch von anderen Bytes ab; häufig letzte Position.
+- **Endianness**: 16-bit LE/BE testen. Monotone Trends/kleine Deltas weisen auf richtige Byteordnung.
+- **Quantisierung**: typische Schrittweiten (z. B. 0.5 °C, 0.25 km/h).
+
+---
+
+## 3) Physik als Filter (Slew-Rate & Grenzen)
+Miss **ΔWert/Δt** robust (95-Perzentil, nicht Max):
+- **Temperaturen**: sehr träge → ΔT/s ≪ 1 °C/s.
+- **Fahrgeschwindigkeit**: 0→100 km/h < 1 s unrealistisch; grob ≤ 30–50 km/h/s (Straße).
+- **RPM**: schnelle Sprünge möglich, aber nicht teleport. 1k→8k in 1–3 s plausibel.
+- **Lenkwinkel**: schnell, aber begrenzt; **Jerk** (ΔΔ/Δt) nicht absurd.
+
+Alles, was diese Checks bricht, ist selten dein gesuchtes physikalisches Signal (oder deine Skalierung ist falsch).
+
+---
+
+## 4) Korrelation & Kausalität
+- **Cross-Korrelation**: RPM ↔ WheelSpeed (Gang drin), Brake-Bit ↔ Pressure, Blinker-Bit ↔ Blinkfrequenz (~1–2 Hz).
+- **Gang** aus Ratio (RPM/Speed) ableiten und Kandidaten validieren.
+- **Event-Marker** setzen und zeitgleichen Byte-Kipp suchen.
+
+---
+
+## 5) Protokoll & Multiplex
+- **ISO-TP**: Muster `0x10 len …` (First Frame), `0x21…` (Consecutive). Enthält selten einzelne Sensorkanäle.
+- **Multiplexer**: Ein Byte schaltet die „Seite“ der Payload um. Erkennbar am Sprungverhalten.
+
+---
+
+## 6) Statistik-Fingerabdrücke
+- **Unique-Ratio** = |unique|/n. Zu klein → Flag/Konstante; moderat → analog.
+- **Entropy** pro Byte → Daten/Checksumme vs. Status.
+- **Plateaus/Hysterese**: aktualisiert nur bei Δ≥Schwelle.
+
+---
+
+## 7) Scale/Offset systematisch schätzen
+- **Scale-Raster**: Dekaden + praxisnahe Werte (0.0625, 0.1, 0.25, 0.5, 0.75, 1, 2, 5, 10 …).
+- **Offset** via **Intervall-Überdeckung**: wähle das Offset, das die meisten Samples in [rmin, rmax] bringt.
+- **Vorzeichen prüfen**: signed/unsigned, ggf. negative Scales zulassen.
+
+---
+
+## 8) Workflow-Cookbook
+1. **Splitten** (Logs → Traces).  
+2. **ID-Explorer/Batch**: Periodizität, Change-Density, 8/16-bit Plots.  
+3. **Range-Fit** mit physikalischen Ranges *und* **Slew-Limits** (Δ/Δt) + **Rate/Jitter-Constraints**.  
+4. **Cross-Checks**: Kandidaten gegen andere Kanäle testen (RPM↔Speed, Brake↔Pressure).  
+5. **Iterieren**: Range/Constraints verfeinern, Plots sichten, Hypothesen anpassen.
+
+---
+
+## 9) Typische Fallen
+- Falsche Endianness → Teleports.  
+- Counter/Checksumme im selben 16-bit-Wort → zuerst trennen.  
+- DLC<8 → 16-bit-Kombis fehlen; keine Dummies einstreuen.  
+- ×10/×100-Skalierung: Δ/Δt wirkt absurd groß.  
+- BCD/ASCII in Diag/Odometer – nicht physikalisch.
+
+---
+
+## 10) Ziel: Berichte statt Bauchgefühl
+Automatisiere Tests & Schwellen. Lass Skripts einen **Analysebericht** schreiben: „PASS (smooth, low jitter, rate ok)“ vs. „FAIL (jitter, slope99 zu hoch, hit-ratio zu klein)“.  
+Das minimiert Confirmation Bias – und macht Ergebnisse reproduzierbar.

+# Kettenöler – CAN Reverse-Engineering Toolkit
+
+Toolsuite (GUI + CLI) zum Analysieren von CAN-Logs im **Kettenöler-Format**.
+Funktionen: Logs **splitten** (pro CAN-ID), **explorative Visualisierung** (8-/16-Bit, LE/BE), **Batch-Analysen** über viele `.trace`, **Ranking** plausibler Signale und **Range-Fit** (lineare Abbildung `phys = raw*scale + offset`), optional **unsupervised** ohne vorgegebene Range.
+
+---
+
+## Features (Überblick)
+
+* **Einheitliche GUI** (`main.py`) mit globalem Header (Workdir, Ordnerstruktur, Log-Auswahl).
+* **Gemeinsame Trace-Auswahl** in allen Trace-Tabs (gleiches Panel, synchronisiert über Tabs):
+
+  * **ID Explorer** (Multi-Select)
+  * **Traces Batch-Analyse** (Multi-Select oder kompletter Ordner)
+  * **Range-Fit** (Single-Select, supervised *oder* unsupervised)
+* **Splitter**: Logs → `.trace` pro CAN-ID (`traces/…`, inkl. `overview_ids.csv`).
+* **Einzel-ID-Explorer**: Plots aller Byte-Kanäle (8-Bit) und Nachbar-Wortkombis (16-Bit LE/BE) + Kurzstatistik.
+* **Batch-Analyzer**: Kennzahlen/Plots für alle `.trace` in einem Ordner, globales Ranking.
+* **Range-/Unsupervised-Fit**:
+
+  * *Supervised*: findet `scale` & `offset` für Zielbereich `[rmin, rmax]` (Offset via Intervall-Überdeckung, Scale aus plausibler Menge).
+  * *Unsupervised*: identifiziert „ruhige“ physikalische Kandidaten ohne Range (Smoothness/Varianz/Rate/Spannweite).
+* **Output-Hygiene**: Ergebnisse stets unter `analyze_out/<timestamp>_<tool>/…`, optionale Zeitstempel-Unterordner verhindern Überschreiben.
+* **Projektdatei** (`Projekt.json`): speichert Workdir, Subfolder, Log-Auswahl, aktiven Traces-Ordner, etc.
+* **„Neuester Split“**-Button: springt in den jüngsten Unterordner von `traces/`.
+
+---
+
+## Repository-Komponenten
+
+* **GUI**
+
+  * `main.py` – zentrales Frontend mit Tabs (Multi-Log Analyse, ID Explorer, Traces Batch-Analyse, Range-Fit).
+* **CLI-Tools**
+
+  * `can_split_by_id.py` – Splittet Logs nach CAN-ID → `.trace`.
+  * `id_signal_explorer.py` – Visualisiert/analysiert eine `.trace` (8-Bit, 16-Bit LE/BE) + `summary_stats.csv`.
+  * `trace_batch_analyzer.py` – Batch-Analyse für viele `.trace` + globales Ranking.
+  * `trace_signal_fitter.py` – **Range-Fit** (scale/offset) **oder** **Unsupervised-Fit** (ohne Range).
+
+> Optional/Alt: `can_universal_signal_finder.py` – ursprünglicher Multi-Log-Analyzer (Ranking auf Rohdatenebene).
+
+---
+
+## Installation
+
+* **Python** ≥ 3.10
+* Abhängigkeiten: `pandas`, `numpy`, `matplotlib`
+* Setup:
+
+  ```bash
+  python3 -m venv .venv
+  source .venv/bin/activate      # Windows: .venv\Scripts\activate
+  pip install -r requirements.txt
+  ```
+
+---
+
+## Logformat (Kettenöler)
+
+Eine Zeile pro Frame:
+
+```
+<timestamp_ms> <TX|RX> 0x<ID_HEX> <DLC> <byte0> <byte1> ... <byte7>
+```
+
+Beispiel:
+
+```
+123456 RX 0x208 8 11 22 33 44 55 66 77 88
+```
+
+---
+
+## Projekt-/Ordnerstruktur
+
+Ein **Workdir** bündelt alles zu einem Fahrzeug/Projekt:
+
+```
+<Workdir>/
+  Projekt.json           # GUI-Einstellungen
+  logs/                  # Input-Logs
+  traces/                # per-ID .trace (vom Split)
+  analyze_out/           # Ergebnisse; je Run eigener Timestamp-Unterordner
+```
+
+**Namenskonventionen**
+
+* Split-Ergebnisse: `traces/<timestamp?>/0x<ID>_<ursprungslog>.trace`
+* Outputs: `analyze_out/<YYYYMMDD_HHMMSS>_<tool>/…`
+
+---
+
+## Modelle-Ordner & Git
+
+Wenn du pro Modell arbeitest, z. B.:
+
+```
+models/
+  Triumph 2023/
+    logs/
+    traces/
+    analyze_out/
+    Projekt.json
+```
+
+Lege in `models/` folgende **`.gitignore`** ab, damit `traces/` und `analyze_out/` **in jedem Modell-Unterordner** ignoriert werden – `logs/` und `.json` bleiben versioniert:
+
+```gitignore
+*/traces/
+*/traces/**
+*/analyze_out/
+*/analyze_out/**
+
+traces/
+traces/**
+analyze_out/
+analyze_out/**
+
+# optional: typos
+*/analyze.out/
+*/analyze.out/**
+analyze.out/
+analyze.out/**
+```
+
+Leere Ordner wie `logs/` ggf. mit `.gitkeep` befüllen.
+
+---
+
+## GUI-Benutzung
+
+```bash
+python3 main.py
+```
+
+### Globaler Header (immer oben)
+
+* **Workdir** wählen, **Logs scannen** → Liste aller gefundenen Logfiles (Multi-Select).
+* Subfolder einstellen: `logs`, `traces`, `analyze_out` (alle **parallel** im Workdir).
+* **Projekt speichern/laden** (`Projekt.json`).
+* Beim Workdir-Wechsel/Projekt-Laden setzt die GUI den **aktiven Traces-Ordner** automatisch auf `traces/` bzw. den **jüngsten** Unterordner.
+
+### Einheitliches Trace-Panel (in allen Trace-Tabs)
+
+* Links: Liste der `.trace`
+* Rechts: **Traces-Ordner wählen**, **Workdir/traces**, **Neuester Split**, **Refresh**, (optional **Alle**, **Keine**)
+* Änderungen am Ordner/Liste wirken **sofort in allen Tabs**.
+
+### Tab: Multi-Log Analyse
+
+* Ranking direkt aus Logs (Include/Exclude-IDs, optional Range mit `scale/offset`).
+* Output: `analyze_out/<ts>_multilog/…`
+* Optional: „Jede Logdatei separat“ → je Log eigener Unterordner.
+
+### Tab: ID Explorer
+
+* **Split** (aus Header-Logauswahl): Logs → `.trace` nach `traces[/<ts>]`, plus `overview_ids.csv`.
+  Danach wird der neue Traces-Pfad **automatisch aktiviert**.
+* **Einzel-ID Analyse** (Multi-Select):
+
+  * Plots: Byte\[0..7] (8-Bit) + LE/BE für Paare (0-1 … 6-7)
+  * `summary_stats.csv` pro Trace
+  * Output: `analyze_out/<ts>_id_explore/…`
+
+### Tab: Traces Batch-Analyse
+
+* Nutzt die gemeinsame Trace-Liste.
+* **Ohne Auswahl** → kompletter Ordner; **mit Auswahl** → es wird ein Subset-Ordner gebaut (Hardlinks/Kopie) und nur dieses analysiert.
+* Parameter: `--rx-only`, `scale`, `offset`, `range-min/max`, `top`, `--plots`.
+* Output:
+
+  * je Trace: `*_combostats.csv` (+ Plots),
+  * global: `summary_top_combinations.csv`
+  * unter `analyze_out/<ts>_trace_batch/…`
+
+### Tab: Range-Fit (Single-Select)
+
+* **Zwei Modi**:
+
+  1. **Supervised** (Range-Min/Max gesetzt): findet `scale` & `offset`, maximiert **Hit-Ratio** im Zielbereich.
+     Output: `<trace>_encoding_candidates.csv` + phys-Plots (Top-N).
+  2. **Unsupervised** (Range leer): bewertet Kandidaten nach **Smoothness**, **Spannweite**, **Varianz**, **Rate**, **Uniqueness**.
+     Output: `<trace>_unsupervised_candidates.csv` + Roh-Plots (Top-N).
+* Optionen: `nur RX`, `negative Scale erlauben` (nur supervised), `Min. Hit-Ratio`, `Min. Smoothness`, `Plots Top-N`, `Output-Label`.
+* Output: `analyze_out/<ts>_rangefit/…`
+
+---
+
+## CLI-Quickstart
+
+### 1) Splitten
+
+```bash
+python3 can_split_by_id.py logs/run1.log logs/run2.log \
+  --outdir <Workdir>/traces/20250827_1200 \
+  --rx-only
+```
+
+### 2) Einzel-ID-Explorer
+
+```bash
+python3 id_signal_explorer.py <Workdir>/traces/20250827_1200/0x208_run1.trace \
+  --outdir <Workdir>/analyze_out/20250827_1210_id_explore
+```
+
+### 3) Batch-Analyse
+
+```bash
+python3 trace_batch_analyzer.py \
+  --traces-dir <Workdir>/traces/20250827_1200 \
+  --outdir <Workdir>/analyze_out/20250827_1220_trace_batch \
+  --rx-only --plots --top 8 \
+  --range-min 31 --range-max 80
+```
+
+### 4) Range-/Unsupervised-Fit (eine `.trace`)
+
+```bash
+# Supervised (z. B. Kühlmittel 31..80°C)
+python3 trace_signal_fitter.py <trace> \
+  --rmin 31 --rmax 80 \
+  --outdir <Workdir>/analyze_out/20250827_1230_rangefit \
+  --plots-top 8 --min-hit 0.5 --allow-neg-scale
+
+# Unsupervised (ohne Range)
+python3 trace_signal_fitter.py <trace> \
+  --outdir <Workdir>/analyze_out/20250827_1240_unsupervised \
+  --plots-top 8 --min-smooth 0.2
+```
+
+---
+
+## Algorithmen & Heuristiken
+
+* **Kombinationen**:
+
+  * 8-Bit: `D0..D7`
+  * 16-Bit (adjazent): LE & BE für Paare `(0,1)…(6,7)`
+    *(32-Bit & bit-gepackte Felder: auf der Roadmap)*
+
+* **Prefilter** (für „ruhige“ physikalische Größen):
+  Mindestanzahl Samples, nicht (nahezu) konstant, keine exzessiven Sprünge (p95 der |Δ| relativ zur Spannweite).
+
+* **Range-Fit**:
+  Für jeden Kandidaten `raw` wird über eine Menge plausibler **Scales** gesucht; für jedes `scale` wird das **Offset** via **Intervall-Überdeckung** bestimmt (`rmin ≤ scale*raw_i + offset ≤ rmax`). Ranking: Hit-Ratio ↓, dann Glattheit (p95 phys) ↑, Rate ↓, n ↓.
+
+* **Unsupervised**:
+  **Smoothness** = `1 − clamp(p95(|Δ|)/span, 0..1)`; zusätzlich **span**, **var**, **rate**, **uniq\_ratio**. Ranking auf diese Metriken.
+
+---
+
+## Tipps & Troubleshooting
+
+* **Keine Kandidaten (Range-Fit)**: `--min-hit` senken, `--allow-neg-scale` testen, Range prüfen, längeres/variableres Log nutzen.
+* **Alles wird gefiltert (Unsupervised)**: `--min-smooth` senken; ggf. `--rx-only` aktivieren.
+* **Leere/komische Plots**: DLC < 8 → teils keine 16-Bit-Kombis; Frames sehr selten → Rate niedrig.
+* **Ordner stets sauber**: Zeitstempel-Unterordner aktiv lassen; pro Run eigene Artefakte.
+
+---
+
+## Roadmap
+
+* 32-Bit-Kombinationen, bit-gepackte Felder.
+* Histogramme, Autokorrelation, Ausreißer-Detektoren.
+* vordefinierte Signal-Profile (z. B. *WheelSpeed*, *CoolantTemp*).

+trace_signal_fitter.py – Advanced Range-/Unsupervised-Fit mit Physik-Constraints & Bericht
+
+Modi:
+1) Range-Fit (supervised): --rmin/--rmax gesetzt → finde scale & offset, maximiere Hit-Ratio in [rmin, rmax].
+2) Unsupervised: ohne Range → plausible Rohsignale nach Smoothness/Var/Rate/Span.
+
+Neu:
+- Periodizität: Rate (Hz), Jitter (std der Inter-Arrival-Times), CV.
+- Slew-Rate: p95/p99 von |Δ|/s (supervised in phys-Einheit, unsupervised normiert auf Roh-Span).
+- Grenzwerte als Argumente (--rate-min/max, --jitter-max-ms, --max-slope-abs, --max-slope-frac, ...).
+- Zusätzlich signed 16-bit Varianten (le16s/be16s).
+- JSON + Markdown-Bericht pro Trace mit PASS/FAIL und Begründungen.
+
+Logformat (Kettenöler):
+<timestamp_ms> <TX|RX> 0x<ID_HEX> <DLC> <byte0> <byte1> ... <byte7>
+
+Outputs:
+- supervised: <trace>_encoding_candidates.csv, Plots, <trace>_report.md, <trace>_report.json
+- unsupervised: <trace>_unsupervised_candidates.csv, Plots, <trace>_report.md, <trace>_report.json

- * @brief Header file for configuration settings and EEPROM operations in the ChainLube application.
+ * Defines EEPROM layout versions, configuration and persistence data structures,
+ * and the public functions for storing, loading, formatting and validating
+ * configuration/persistence records.
  *
- * This file defines configuration settings for the ChainLube project, including default values,
- * EEPROM structures, and functions for EEPROM operations. It also defines enums for different sources
- * of speed input, GPS baud rates, and CAN bus sources. Additionally, it includes functions for EEPROM handling
- * such as storing, retrieving, and formatting configuration data.
- *
- * @author Marcel Peterkau
- * @date   09.01.2024
+ * Notes:
+ * - The system always boots with defaults in RAM; EEPROM is optional.
+ * - DTC handling for EEPROM availability and integrity is centralized in EEPROM_Process().
