Design Concept: Ethernet Controller For Embedded IoT Systems And Automotive Networking

We at Copperhill Technologies have plans to create gateways for automotive networking, which includes serial protocols such as Automotive Ethernet, CAN (Controller Area Network), and LIN (Local Interconnect Network). The following focusses on the Ethernet part of the concept, where Ethernet also applies to Internet-of-Things (IoT) and Industrial-Internet-of-Things (IIoT) applications. The basic idea is to build [...]

Quick Reference: Controller Area Network - CAN Bus - Versus Industrial Ethernet

At first glance, a comparison of the two networking technologies, Controller Area Network (CAN Bus) and Industrial Ethernet may appear as a battle between David and Goliath. On one side, you have the clear underdog, CAN Bus with its 1 Mbit/sec baud rate, its limited network length, and a maximum data length of 8 bytes per message. [...]

SAE J1939 Message Format And Interpretation Of PGNs

It happens on a regular basis that I am contacted by a user of our SAE J1939 ECU Simulator Board With USB Port, complaining that our device does not display a PGN correctly or modifies the PGN before transmitting. The real problem here is a misinterpretation of the PGN and its purpose. For instance, a PGN [...]

The Benefits Of Controller Area Network - CAN Bus - For Embedded Applications

The following is an excerpt from  A Comprehensible Controller Area Network by Wilfried Voss. Controller Area Network, like any field-bus system based on serial communication, will reduce wiring, which was initially considered only as an advantageous side effect.  Distributed control, i.e., the use of a multi-processor system, will consequently result in increased performance, and the vastly reduced costs [...]
