Featured Examples

Get Started with J1939 Parameter Groups in MATLAB

Create and manage J1939 parameter groups using information stored in DBC-files. This example uses file J1939.dbc. Creating and using parameter groups this way is recommended when needing to transmit data to a J1939 network.

Replay J1939 Logged Field Data to a Simulation

Replay J1939 data from a BLF-file acquired from a J1939 system in a real-world application, such as a vehicle running in the field. The Simulink model runs a simple horsepower estimator algorithm to trigger a fault that might have occurred in the field. The example takes you through a part of the model-based workflow using field data to recreate a fault that was present in the Simulink algorithm before it was deployed onto an ECU, and can be extended to test any algorithm model to debug faults.
