This example shows you how to create, receive and process messages using information stored in DBC files. This example describes the workflow for a CAN network, but the concept demonstrated also applies to a CAN FD network.

Load .dbc Files and Create Messages Vector CAN Database Support. Vehicle Network Toolbox™ allows you to use a Vector CAN database. The database .dbc file contains definitions of CAN messages and signals. Using the information defined in the database file, you can look up message and signal information, and build messages.

With the add_block (Simulink) and set_param (Simulink) functions of Simulink, one can add and fully configure Vehicle Network Toolbox™ blocks to add network communication to a basic algorithm. The DBC file contains the CAN messages and signal details. The primary focus is to programmatically configure CAN and CAN FD Pack and Unpack block ...

candb = canDatabase('dbfile.dbc') creates a handle to the specified database file dbfile.dbc. You can specify a file name, a full path, or a relative path. MATLAB ® looks for dbfile.dbc on the MATLAB path. Vehicle Network Toolbox™ supports Vector CAN database (.dbc) files.

With the add_block and set_param functions of Simulink, one can add and fully configure Vehicle Network Toolbox (VNT) blocks to take a basic algorithm and add network communications. The DBC-file contains the CAN messages and signal details. The primary focus is to programmatically configure CAN and CAN FD Pack and Unpack block parameters. This ...

Replay Pre-Recorded CAN Data. Data logged from a CAN network is provided in the file CANExplorerData.mat. The data is saved in timetable format and the time range spans about 60 seconds. Replay the CAN data onto MathWorks Virtual 1 Channel 2 for CAN Explorer to receive on MathWorks Virtual 1 Channel 1 in the same MATLAB instance.

All the messages in the log file are imported as an array of CAN message objects. After importing, you can analyze, transmit, or replay these messages. canMessageImport assumes that the information in the imported log file is in a hexadecimal format, and that the timestamps in the imported log file are absolute values.

2020年5月8日 · While you cannot concatenate multiple DBC objects or attach multiple to the same CAN Channel, there is a workaround for accomplishing the same end result. Generally, the reason you would want to do this is because your message definitions are split between two different database files, and therefore you need both DBC files to decode all of your ...

In the same way, make a connection between the output port of the CAN Pack block and the input port of the CAN Transmit block. The CAN Configuration block does not connect to any other block. This block configures its CAN channel for communication. Step 6: Specify the Block Parameter Values
