Release v2.02

We are pleased to announce the release of CAN Data Converter v2.02.
This version introduces CAN database consistency checking functionality, significantly improving the reliability of data conversion.

CANDataConverter

✨ New Features

CAN Database Consistency Check

  • DLC (Data Length Code) Validation
    • Automatic comparison between DLC defined in CAN message definitions and actual CAN data DLC
    • Automatically skip inconsistent data and continue processing
    • Log inconsistency information for data quality visibility

🔧 Improvements

  • Enhanced Data Conversion Robustness

    • Prevent crashes and processing errors caused by invalid CAN data
    • Ensure conversion process stability through proper handling of DLC-mismatched data

  • Improved Troubleshooting Efficiency

    • Detailed error logging enables quick identification of data quality issues
    • Record information about skipped messages to support data validation

📝 Behavior Specification

When DLC mismatch is detected:

  1. Skip processing of the corresponding CAN message
  2. Output warning message to log file (Message ID, Expected DLC, Actual DLC)
  3. Continue conversion process with valid data only

🐛 Bug Fixes

  • Fixed program crashes caused by inconsistencies between CAN data and dbc definitions

📦 Requirements

  • Python 3.8 or higher
  • Required libraries: cantools, asammdf, pandas, openpyxl

📖 Usage

For detailed usage instructions, please refer to the README.

Release v2.02

CANデータ変換ツールのv2.02をリリースしました。
このバージョンでは、CANデータベース（.dbc）との整合性チェック機能を追加し、データ変換の信頼性を大幅に向上させました。

✨ 新機能

CANデータベース整合性チェック機能

  • DLC（Data Length Code）検証機能の実装
    • CANメッセージ定義のDLCと実際のCANデータのDLCを自動比較
    • 不一致が検出された場合、該当データを自動的にスキップし、処理を継続
    • 不一致情報をログに出力し、データ品質の問題を可視化

🔧 改善内容

  • データ変換の堅牢性向上

    • 不正なCANデータによるクラッシュや処理エラーを防止
    • DLC不一致データを適切にハンドリングすることで、変換処理の安定性を確保

  • トラブルシューティングの効率化

    • 詳細なエラーログにより、データ品質の問題を迅速に特定可能
    • スキップされたメッセージの情報を記録し、データ検証を支援

📝 動作仕様

DLC不一致が検出された場合の挙動：

  1. 該当CANメッセージの処理をスキップ
  2. ログファイルに警告メッセージを出力（メッセージID、期待DLC、実際のDLC）
  3. 正常なデータのみを対象として変換処理を継続

🐛 バグ修正

  • CANデータとdbc定義の不整合によるプログラムクラッシュを修正

📦 動作環境

  • Python 3.8以上
  • 必要なライブラリ：cantools, asammdf, pandas, openpyxl

📖 使い方

詳細な使用方法については、READMEをご参照ください。
