One of the first questions engineers ask when starting with SAE J1939 development is: “Which hardware platform should I use?” The good news is that there is no shortage of choices. Over the years I have worked with numerous embedded platforms, development environments, and operating systems. They all have their…

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…
If you spend enough time around CAN Bus and SAE J1939 discussions, you’ll eventually encounter a statement along these lines: “Why implement a J1939 stack in firmware when Linux already supports J1939?” It’s a fair question. Modern Linux kernels include native J1939 support as part of the SocketCAN framework, and…
