Programming PiCAN Boards with Python: A Practical Guide for Raspberry Pi CAN Applications
The Raspberry Pi has become one of the most popular platforms for developing CAN bus applications. Whether you are working with industrial equipment, agricultural machinery, marine electronics, automotive systems, or SAE J1939 networks, combining a Raspberry Pi with a PiCAN board provides a powerful and cost-effective development platform. One of the biggest advantages of this setup [...]
Why CAN Bus Refuses to Die: What CAN FD and CAN XL Reveal About the Strength of Classical CAN
For more than 25 years, I have been working with CAN (Controller Area Network) technology. During that time, I have lost count of how many times industry experts, analysts, and technology journalists predicted its imminent demise. First, it was Ethernet. Then came FlexRay. Later, it was Automotive Ethernet. More recently, CAN FD and now CAN XL have been presented [...]
CAN Bus Programming in Python for Automotive, Industrial Automation, and Robotics
The Controller Area Network (CAN bus) is a resilient, lightweight, and efficient communication protocol originally developed by Bosch in the 1980s for in-vehicle networks. It allows multiple microcontrollers (ECUs) and devices to communicate without a central host, using a multi-master, message-oriented design. Over the decades, CAN bus has expanded beyond its automotive roots into domains [...]
Mastering CAN Bus: Essential Guide to Understanding and Troubleshooting Vehicle Networks
In today’s world of connected vehicles and industrial automation, understanding the details of networked communication protocols has become a pivotal skill for engineers and technicians alike.

Migrating Legacy CAN Systems to Modern Architectures: Practical Steps & Pitfalls
The Controller Area Network (CAN) protocol has been the backbone of reliable embedded communication for decades. From passenger cars to heavy-duty trucks, from industrial machinery to marine electronics, CAN has delivered deterministic, robust, and low-cost networking. But as data demands grow—driven by autonomous features, connected vehicles, and Industry 4.0—Classical CAN’s 1 Mbit/s bandwidth and 8-byte [...]
Classical CAN vs. CAN FD in Automotive, Medical Devices & Robotics – Key Differences and Usage
Controller Area Network (CAN) is a robust serial bus widely used in embedded systems across industries like automotive, medical devices, and robotics. “Classical” CAN (the original CAN 2.0 standard) has served reliably for decades in vehicle ECUs, industrial machines, and more. However, modern systems demand higher data throughput and efficiency than classical CAN’s 1 Mbit/s [...]
