When the target DBC file and ECU follow the SAE-J1939 standard, the CAN reader application of the provider should read
PGN(Parameter Group Number)-based Data rather than CAN frames directly. Otherwise it is possible to miss signals from
large-sized messages that are delivered with more than one CAN frame because the size of each of these messages is bigger
than a CAN frame's maximum payload of 8 bytes. To enable the J1939 mode, simply put --use-j1939 in the command when running dbcfeeder.py.
Support for J1939 is provided by means of the can-j1939 package. The J1939 feature is in Alpha status (see KUKSA Component Maturity ) as no public test cases or example configurations exist.
