J1708 to J1939 Conversion Made Smarter: The Truth Behind Protocol Gateways
I regularly receive inquiries about converting from SAE J1708/J1587 to SAE J1939. Most often, the goal is to bridge old and new technologies—for example, connecting a modern J1939-based dashboard to a legacy J1708-based diesel engine. There are other scenarios, but this one comes up frequently. The logical next step is to look for a protocol [...]
Error Reporting in SocketCAN with Specific Reference to the MCP2515 CAN Controller
SocketCAN is a set of open-source CAN drivers and a network stack, included in the Linux kernel, which allows CAN devices to be accessed via standard socket APIs. It provides a flexible and extensible framework for CAN communication, diagnostics, and application development. One powerful feature of SocketCAN is error reporting via special CAN frames, which is [...]
Unlocking Vehicle Intelligence: A Practical Guide to CAN and LIN Bus Networks
Modern vehicles contain dozens of electronic control units (ECUs) that must communicate reliably to coordinate engine, transmission, braking, body functions, and more. Two key networking technologies enabling this in-car communication are the Controller Area Network (CAN) and the Local Interconnect Network (LIN). CAN and LIN buses each have distinct architectures and roles: CAN is a [...]
