Configuration-Free Wireless CAN Bus Bridge Connects Two CAN Bus Networks With Different CAN Bus Bitrates
Kvaser, a specialist in CAN Bus (Controller Area Network) development, introduced their Air Bridge Light HS, a wireless CAN Bus bridge to connect CAN networks. Comprising a preconfigured pair of plug-and-play units, with integrated antennas and rugged housings, the Kvaser Air Bridge Light HS provides a method of raw CAN Bus data exchange. Kvaser Air Bridge Light HS, [...]
Data Acquisition from Light-Duty Vehicles Using CAN Bus, Including OBD-II, SAE J1939 Protocols
The Society of Automotive Engineers (SAE) has published a book that guides readers on how to collect and evaluate data from CAN Bus in-vehicle networks of light-duty (LD) vehicles. Data Acquisition from LD Vehicles Using OBD and CAN by Eric Walter and Richard Walter addresses product engineers, service technicians, fleet managers, and all interested in acquiring data efficiently [...]
Touch Encoder With SAE J1939 Interface Replaces Conventional Touch Displays, Keypads And Rotary Switches
The Touch Encoder by Grayhill is a fusion of the functionality of standard touch displays, keypads and rotary switches that can support various languages or end product configurations. Whether it's robotics, automation, or other user interface applications, anyone can design a custom experience with great options. The new Touch Encoder technology applies to many markets, especially where shrinking [...]
Building Embedded Systems With ARM Technology For Industrial And Commercial Applications
Practical Microcontroller Engineering with ARM Technology presents the full scope of components and materials related to ARM Cortex–M4 microcontroller systems.Chapters 2 through 9 provide the fundamentals and detailed discussions about ARM Cortex-M4 MCU applications with the most universally used peripherals such as flash memory, EEPROM, ADC, DAC, PWM, UART, USB, I2C, SSI, LCD, and GPTM. [...]
Intelligent CAN Bus Data Logger Device With Two CAN Bus Ports
The CAN-Logger200 from ICPDAS is equipped with two M12-designed CAN Bus interfaces and an exchangeable SD card for temporary data storage. A DIP (dual in-line package) switch activates/deactivates the integrated 120 Ohm termination resistor. The user can individually set the CAN Bus bitrate (up to 1 Mbit/s), the CAN Bus protocol (11‑bit identifier base frame format or 29‑bit [...]
Ruggedized CAN Bus - IoT Gateway Connects Vehicles To The Cloud Via Wireless Or Cellular Interfaces
TTControl, a joint-venture company of TTTech Computertechnik and Hydac International, introduced an end-to-end solution connecting vehicles and mobile machines via a cloud platform for data processing and analysis. The product was designed to enable OEMs (Original Equipment Manufacturer) and fleet owners to optimize their fleet management and machine design. It also serves to assure the availability [...]

Microcontrol announced its μCAN.8.dio-Snap I/O module with CANopen FD support. For more than 20 years, Microcontrol - based in Troisdorf near Cologne/Germany - has specialized in producing CAN applications for demanding industries as, for instance, mechanical and automotive industries but also renewable energy and medical technology. They provide solutions to transmit analog measurement signals to a Fieldbus interface [...]
Engineering Note: Reverse Engineering Of CAN Bus Communication
There are many applications, in which one may need to reverse engineer CAN Bus communication. Examples are automotive competitor analysis, telematics applications such as fleet management, and disabled driver applications. The typical reverse engineering process is concerned with moving a sensor and watching the CAN Bus network for message changes. For example, wind down a door [...]
Engineering Note: Implementing SAE J1939 In Vehicle Design
Heavy-duty commercial and off-highway vehicles, such as agricultural and construction equipment, pose various electrical and mechanical engineering challenges. These vehicles must be efficient, durable, and reliable as they have long service lives in demanding environmental conditions that can include extreme temperature, dirt, dust, and altitude. A key consideration during commercial and off-highway E/E architectural definition is the SAE [...]
Controller Area Network (CAN Bus) - Bit Timing And Synchronization
The following is an excerpt from A Comprehensible Controller Area Network by Wilfried Voss. As was explained in Chapter 7.1 - Bit Coding the CAN standard uses the Non-Return-to-Zero (NRZ) bit coding, which provides a maximum of data transport capacity, but in turn lacks sufficient means of bit synchronization between sender and receivers in a CAN network.Bit Stuffing, i.e. the [...]
