Designing a CAN Bus device that performs well under ideal conditions is relatively straightforward. The real challenge begins when the network no longer behaves as expected. In the field, connectors loosen, ECUs lose power, messages are delayed, wiring deteriorates, and configuration errors inevitably occur. A robust CAN device must continue…

If you are serious about developing CAN or CAN FD applications, there is one tool that will save you more time, eliminate more frustration, and improve your software quality more than almost anything else: a professional CAN analyzer. Many engineers begin by connecting a microcontroller to a CAN network, sending…
If you’ve worked with SAE J1939 long enough, you’ve probably experienced the frustration of connecting two devices to a CAN bus and seeing… absolutely nothing happen. No engine data. No diagnostic messages. No responses to requests. Just silence. The good news is that most J1939 communication problems are caused by…
One of the questions that recently crossed my mind was whether our existing SAE J1939 gateways and monitoring tools could be useful in the agricultural sector, specifically for monitoring ISOBUS networks. The short answer appears to be: Yes, in many cases they can. The longer answer is a bit more…
This book provides a hands-on introduction to Controller Area Network (CAN) bus technology through practical projects using the Arduino Uno and the Raspberry Pi 4. By working with readily available CAN bus interface modules, readers learn how to design, build, debug, and test CAN-based systems without the need for specialized…
