Building High-Speed Data Loggers with Teensy Need to capture, process, and transmit large amounts of CAN Bus data in real time? A modern data logger should do much more than simply record messages. Discover how the Teensy platform enables high-performance data logging with Classical CAN, CAN FD, multiple CAN channels, and Ethernet for Industrial IoT, gateway, and edge computing applications—all while remaining compatible with the Arduino IDE.

Most engineers troubleshoot CAN networks by watching messages. The CAN controller is watching the network itself. The latest JCOM1939 Monitor now displays the controller's Transmit Error Counter (TEC), Receive Error Counter (REC), and current error state (Error Active, Error Passive, Bus Off), giving you immediate insight into wiring faults, missing termination, baud-rate mismatches, and malfunctioning CAN nodes. If your CAN interface driver doesn't provide access to these error counters, you're missing one of the most valuable diagnostic tools available.

Ever wondered why your CAN-to-USB interface doesn't work with every CAN application? A customer recently asked if they could use our JCOM1939 Monitor software with an existing IXXAT interface. The short answer was "No"—and the reason reveals a long-standing challenge in the CAN Bus industry. In this article, I explain why CAN hardware and software are typically tied to the same manufacturer, why there is still no universally accepted interface standard, and how that realization shaped the design philosophy behind our own products: Keep It Simple.

After years of teaching SAE J1939, I came to one conclusion: Embedded developers don’t need to understand every detail of the standard before writing their first application. That’s why I’m writing a completely different book. Instead of following the structure of the SAE documents, J1939 Development for Embedded Systems takes a programmer-first approach, focusing on the concepts you actually need to build working applications using Arduino, ESP32, Teensy, and other embedded platforms. Even better, every example is based on the open-source ARD1939 protocol stack, so you’ll be working with real code—not just theory.
