TīmeklisWhat is J1939? • It is a standard maintained by the Society of Automotive Engineers (SAE) • The standard defines how information is transferred across a network to allow ECUs (i.e. computers) to communicate information. (e.g. vehicle speed) • Think of J1939 as a software specification that rides on top of a CAN bus. TīmeklisIn practice, J1939 conversion is often done by extracting the 18-bit J1939 PGN from the CAN ID and the DBC ID and then comparing the PGNs. The method depends on your software. In the CANedge tools like asammdf and our Python API tools, loading a J1939 DBC will automatically make the tools use J1939 PGN matching.
