Import, Export, and Decode Vehicle Data

Import, decode, and export vehicle network log files in MATLAB using Vehicle Network Toolbox (VNT).

When to Use

• Reading .mf4/.mdf/.dat, .blf, .asc, or .txt vehicle bus log files
• Decoding raw CAN/CAN FD frames to signals via DBC or ARXML databases
• Demultiplex signals from raw CAN/CAN FD frames via DBC databases in the case of simple multiplexing (R2026a or earlier)
• Decoding LIN frames via LDF databases (R2025a+)
• Handling polymorphic return types from VNT read functions
• Writing MATLAB timetable data to MDF/MF4 files with mdfWrite
• Writing CAN/CAN FD message data to BLF files with blfwrite
• Converting unsupported timetable types (logical, categorical, cell, datetime columns) for MDF export
