If you work with SAE J1939 long enough, there comes a point where generic CAN monitoring software is no longer enough. You need an application that is tailored to your own project, whether that means displaying proprietary parameters, automating diagnostics, logging data, testing ECUs, or integrating J1939 into a larger…

If you are serious about developing CAN or CAN FD applications, there is one tool that will save you more time, eliminate more frustration, and improve your software quality more than almost anything else: a professional CAN analyzer. Many engineers begin by connecting a microcontroller to a CAN network, sending…
A customer recently asked me a seemingly simple question: “Can I use your JCOM1939 Monitor software with my existing IXXAT CAN-to-USB interface?” Although the question was specifically about SAE J1939, the underlying issue has nothing to do with J1939. It is a problem that has existed in the CAN Bus…
SAE J1939 development has evolved far beyond traditional automotive Electronic Control Units (ECUs). Today, engineers can build J1939-enabled systems using low-cost embedded platforms such as the ESP32 and the Raspberry Pi. While both platforms can successfully communicate on a J1939 network, they serve very different purposes. The question is not…
The PiCAN series from Copperhill Technologies is a line of CAN Bus interface boards (HATs) designed for the Raspberry Pi. These add-on boards are widely recognized as powerful and versatile, enabling seamless integration of the Raspberry Pi with Controller Area Network (CAN) bus systems. CAN bus is the robust vehicle…
Developing on the CAN Bus using higher-layer protocols—like SAE J1939, NMEA 2000, or CANopen—offers powerful features in vehicle, marine, and industrial systems. Yet this versatility comes with complexity. Whether you’re using off-the-shelf hardware (like PiCAN, Teensy, ESP32) or designing custom CAN hardware, having the right tools and a systematic troubleshooting…
Developing applications and hardware for CAN Bus (Controller Area Network) can range from hobbyist projects to professional-grade industrial systems. Regardless of whether you are working with protocols such as SAE J1939 (heavy-duty vehicles), NMEA 2000 (marine electronics), or CANopen (industrial automation), there are some universal tools and practices you’ll need.…
