I’m new to CAN and am trying to understand a certain command on my truck’s CAN bus.  I’d like to record the data, break it down, and then resend it. Could the Komodo CAN Interfaces help me?

Thanks for your question! The Komodo CAN Duo Interface, as well as the Komodo CAN Solo Interface, can definitely help you record, analyze/break down, and send CAN data.  The main difference between the two units is that Komodo Duo interface has 2 CAN channels where you simultaneously monitor two different buses or record and send data at the same time.  The Komodo Solo interface has one CAN channel and can monitor or send data.

There are many ways to connect to the Komodo interfaces: you can use the Komodo GUI software, Data Center Software, and the Komodo Software API.

Here is a summary of the software tools and how they can be used with the Komodo CAN interface:

• The Komodo GUI Software provides full access to all Komodo interface functionality - you can do the work without writing custom software to control the Komodo interface: you can send data, do some basic monitoring, and batch commands. You can easily interface with accessory boards such as the CAN/I2C Activity Board Pro, configure GPIO settings, use the Batch Mode to deliver specific CAN data packets and more.
• The Data Center Software is purely a bus monitoring software application that displays real-time captured CAN bus data, which can then be filtered. This also simplifies your work by eliminating the need to write custom software to control the Komodo interface. To help you analyze the data, multiple views, such as Block, Hierarchical and more are available.
• The Komodo Software API is used to control the Komodo interface, and to customize a program for specific setup requirements. You will need to write your software applications, but the API gives you the most control over the Komodo interface.  The API supports multiple OSs (Windows, Linux, and Mac) and multiple languages (C, Python, Visual Basic, and C#), it also includes examples that can be used as-is or customized for your specific needs. For more information about Komodo API, please refer to the section 5 of the Komodo CAN Interface User Manual.

We provide other tools that can help you advance your understanding and usage of the Komodo CAN interface.

• The CAN/I2C Activity Board Proi s an excellent development tool for the embedded systems developers, which can be used with the GUI Software as well as API.

• For online tutorials and guidelines, we have articles in our knowledge base. We also have a video that shows you how to use the Komodo CAN Interface with the Data Center Software to analyze and capture and analyzed CAN traffic data
• You can also leverage the Komodo CAN interface with other tools such as the uTasker. You may find this useful, especially for the development, troubleshooting and simulation of microprocessors. You can see an example of using the Komodo CAN interface and the uTasker together on youtube.
