CAN Dashboard
HANtune can be used to present CAN-traffic in a human readable format. That means that the raw CAN-data is converted to physical values and presented along with the appropriate name and unit. To be able to do this, a descriptive file is needed which contains this information: the DBC file.
These files have the following convention:
CAN-Message: The entire message frame, belonging to one CAN-ID
CAN-Signal: One CAN-Message contains one or more signals. A signal has a unit and name, e.g. oilTemp [°C]
To start using HANtune as a CAN-dashboard, the following two elements are needed:
A CAN database file (DBC) which matches the messages on the CAN-bus. This file with the .dbc file extention following the .dbc (quasi-) standard. This file defines the identifier, name, scaling, offset, etc. of CAN massages, enabling HANtune to present the raw CAN-data in a human readable format.
- In the side-tab “Project Data” there is a folder named “DBC files”. Right click this folder and choose “Add DBC file”
- Browse to the DBC (*.dbc) file which you want to use, select it and press “Open”
- The file has now been added to your project but is not loaded. To load, double click on the DBC file which you want to load or right click and choose “load file”
(For more info go to: Chapter xx how to add a DBC file)
A Layout which contains tabs with editors and/or viewers. A default Layout called “Unnamed” is already available and loaded. You can find the CAN messages in the “CAN elements” side tab.
Editors: can be used to send CAN-messages to the CAN-bus
Viewers: can be used to visualize CAN-messages from the CAN-bus
To create an editor (send CAN-messages):
- Go to the tab “CAN Elements”
- Search for the CAN-signal which needs to be sent
- Drag-and-drop the CAN-signal to your layout (empty white space)
- Choose the right type of editor

To create a viewer (visualize CAN-messages):
- Go to the tab “CAN elements”
- Search for the CAN-signal which needs to be showed
- Drag-and-drop the CAN-signal to your layout (empty white space)
- Choose the right type of viewer

You are now ready to connect to the target. Check the communication settings by clicking the menu item “Communication” (top of screen), “Communication settings”. If these settings are correct and your target is powered on and connected to the PC, press F5 and click “Connect and request” to connect.
For more info on establishing a connection see: chapter 0 how to make a connection with a controller
To save your project: click “File”, “Save Project as…” in the menu. Choose a filename and the path where to save your project and click “Save”. Your project will be saved as a .hml file.
Hint: Try to use multi-select! Some editors and viewers are capable of showing more than just one signal or parameter.
