Why Teensy Is One of the Best Microcontrollers for CAN Bus Applications
When engineers begin working with Controller Area Network (CAN) systems, one of the first questions is usually, "Which microcontroller should I use?" The answer depends on the application, but one platform consistently stands out for its combination of performance, flexibility, and ease of development: Teensy. Originally developed by PJRC, the Teensy family has earned an excellent [...]
ESP32 CAN Data Logger over Wi-Fi and Bluetooth: Build a Remote CAN & CAN FD Monitoring System
Industrial machines, commercial vehicles, agricultural equipment, marine electronics, and factory automation systems all generate valuable information over the CAN bus. The challenge is rarely collecting the data—it's accessing that data without being physically connected to the network. Imagine monitoring an engine from your office, recording CAN FD traffic from inside an industrial cabinet without opening the [...]
Building High-Speed Data Loggers with Teensy: From CAN Bus to Connected IoT Systems
Data logging has evolved far beyond simply recording CAN messages to a memory card. Today's engineers expect real-time visualization, multi-channel data acquisition, remote connectivity, cloud integration, and support for modern protocols such as CAN FD—all while maintaining deterministic performance and low latency. If you are designing a professional-grade data logger, the choice of hardware platform can [...]
Build a Professional SAE J1939 Test Bench for Under $200
Imagine you're developing—or simply testing—a J1939 device. Perhaps it's a dashboard, a CAN gateway, a telematics unit, a data logger, a display, or a diagnostic application. You don't have access to a truck, and even if you did, you probably wouldn't want to leave the engine running all day just to verify that your software [...]
Turning a Raspberry Pi into a Professional CAN Data Logger
One of the greatest advantages of the Raspberry Pi is its ability to transform from a low-cost single-board computer into a surprisingly capable engineering platform. Add a CAN Bus interface, and it becomes much more than a hobbyist computer—it becomes a powerful tool for data acquisition, diagnostics, and embedded systems development. Whether you're troubleshooting a machine [...]
SAE J1939 Development: Why Every Engineer Needs a Stable J1939 Test Network
Developing an SAE J1939 application should be challenging because of your application logic—not because your test environment keeps changing. Unfortunately, that’s exactly what happens in many development projects. An engineer designs a new J1939 ECU, writes the firmware, connects it to another prototype node, and immediately starts chasing communication problems. The problem is that both nodes are [...]
Arduino Due Dual CAN Bus Development Platform for Rapid CAN Bus and SAE J1939 Prototyping
One of the biggest obstacles in CAN bus development is not understanding the CAN protocol itself—it is finding a development platform that lets you move from an idea to a working prototype without spending weeks configuring hardware, writing low-level drivers, or debugging interface electronics. Whether you are developing an automotive controller, an industrial CAN node, an [...]
Developing SAE J1939 Applications with ARD1939 and Copperhill Technologies Hardware
One of the challenges of developing SAE J1939 applications is finding a protocol stack that is both affordable and flexible enough for prototyping, education, and custom embedded projects. To address this need, we developed ARD1939, a portable C++ SAE J1939 protocol stack that serves as the software foundation for many of our development projects and examples. Originally [...]
Analog to NMEA 2000 Converter: Upgrade Legacy Boat Sensors to Digital NMEA 2000 Monitoring
Many boats still rely on traditional analog gauges and sensors for monitoring engine performance and tank levels. While these systems are reliable, they cannot share information with modern multifunction displays (MFDs), digital dashboards, chartplotters, or onboard monitoring systems. An Analog to NMEA 2000 Converter bridges that gap by translating analog sensor signals into standardized NMEA [...]
Raspberry Pi CAN FD and 10BASE-T1L: Building Industrial IoT and Embedded Networking Solutions
The Raspberry Pi has become one of the world’s most popular embedded computing platforms. It is inexpensive, powerful, runs a full Linux operating system, and supports countless programming languages and development tools. Yet many engineers quickly discover a limitation when they move from software development into real-world industrial applications. The Raspberry Pi provides Ethernet, USB, Wi-Fi, Bluetooth, [...]
