Why CAN Bus Is One of the Most Reliable Communication Systems Ever Created
When engineers design communication systems for vehicles, industrial machinery, agricultural equipment, marine electronics, and embedded control systems, reliability is often more important than raw speed. A lost message in a music streaming application may go unnoticed. A lost message containing engine speed, brake status, steering angle, or hydraulic pressure can lead to equipment malfunction, downtime, or [...]
CAN, SAE J1939, and NMEA 2000 Development with Raspberry Pi and PiCAN HATs
The Raspberry Pi has evolved far beyond its origins as an educational computer. Today, it serves as a powerful platform for industrial automation, vehicle networking, marine electronics, telematics, data logging, and rapid embedded systems prototyping. When combined with the PiCAN family of Raspberry Pi HATs available from Copperhill Technologies, the Raspberry Pi becomes a versatile CAN [...]
ESP32 TWAI Driver Explained: A Practical Guide to CAN Bus Programming
The ESP32 has become one of the most popular microcontrollers for CAN bus applications. Whether you are building industrial controllers, SAE J1939 devices, NMEA 2000 products, robotics systems, or automotive prototypes, the ESP32 provides a powerful and cost-effective platform with a built-in CAN controller. Yet, many developers are confused when they encounter the term TWAI in [...]
ESP32S3 CAN & LIN-Bus Board – Accelerating CAN-to-LIN Gateway Development
Modern vehicles and industrial machines increasingly rely on multiple communication networks. While CAN Bus serves as the backbone for critical control systems, LIN (Local Interconnect Network) provides a low-cost solution for intelligent sensors, switches, actuators, and body electronics. In many applications, engineers need a reliable method to exchange data between these two networks. The ESP32S3 CAN [...]
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 [...]
