Question 1

How to simulate CAN signals without physical hardware in CANdevStudio?

Accepted Answer

Use virtual CAN interfaces like vcan on Linux by loading the kernel module and setting up a virtual device, then configure the CanDevice backend as 'socketcan' with the interface name. Alternatively, use cannelloni for Ethernet-based tunneling, as described in the VCAN and Cannelloni sections.

Question 2

CANdevStudio vs Vector CANoe: which is better for automotive testing?

Accepted Answer

CANdevStudio is a cost-effective, open-source tool ideal for simulation and extensibility with scripting, while Vector CANoe offers comprehensive commercial features and support for complex, enterprise-grade testing. Choose CANdevStudio for flexibility and savings, but opt for CANoe if you need certified tools and extensive protocol support.

Question 3

How to add a custom CAN device plugin in CANdevStudio?

Accepted Answer

Use the templategen tool to generate a new component skeleton, then modify the source files to define inputs, outputs, and logic. Build the project with CMake, and the plugin will integrate automatically, as outlined in the 'Adding new components' section.

Question 4

Does CANdevStudio support J1939 or other proprietary CAN protocols?

Accepted Answer

It supports generic CAN simulation with DBC files for signal definitions, but specific protocols like J1939 require custom components or scripting. The modular architecture allows extensions, but out-of-the-box support is limited to standard CAN features.

Question 5

How to filter incoming CAN frames by ID in CANdevStudio?

Accepted Answer

Use the CanRawFilter component with Qt regular expressions to define rules for accepting or dropping frames based on ID or payload. Rules are matched top-down, and examples are provided in the CanRawFilter section, such as using '^[23]..$' for IDs in the 0x200-0x300 range.

Question 6

What are the system requirements for running CANdevStudio on Windows?

Accepted Answer

Requires Visual Studio 2019 redistributables for standalone packages, and Qt libraries if not using the bundled version. Prebuilt packages are built with VS2019, and setup involves CMake configuration, as detailed in the Windows build instructions.
