Welcome to the J1939 Development Center, your resource for practical SAE J1939 programming and embedded system development. Whether you are developing a custom ECU, designing a CAN gateway, building a data logger, or creating a vehicle simulator, this section brings together tutorials, programming examples, development tools, and technical resources to help you build real-world J1939 applications.
The focus is on practical implementation rather than theory. Here you will find the ARD1939 protocol stack, programming examples, development hardware, technical articles, and information on my books—all designed to help engineers and embedded developers accelerate their SAE J1939 projects with confidence.

ARD1939 is an open-source SAE J1939 protocol stack for Arduino, ESP32, Teensy, and other embedded platforms. It provides a practical foundation for developing ECUs, CAN gateways, data loggers, and diagnostic applications, and serves as the software platform for the programming examples throughout this website and my J1939 development projects. 
J1939 Development for Embedded Systems is a practical guide to developing SAE J1939 applications on Arduino, ESP32, Teensy, and other embedded platforms. Through real-world programming examples and the open-source ARD1939 protocol stack, the book takes you from protocol fundamentals to building complete J1939-enabled embedded applications. 
Programming Examples provide practical, fully explained projects that demonstrate key SAE J1939 concepts and embedded programming techniques. Covering Arduino, ESP32, Teensy, and the ARD1939 protocol stack, these examples help you develop real-world J1939 applications with confidence. In preparation…
Development Hardware includes a carefully selected range of tools for SAE J1939 monitoring, simulation, diagnostics, and embedded development. These are the same hardware platforms used throughout the tutorials, programming examples, and development projects featured on this website. In preparation…This is a work in progress… Further information will be added frequently.
