CAN Bus and SAE J1939 Wiring Requirements And Trouble-Shooting
Controller Area Network (CAN) is a serial network technology that was originally designed for the automotive industry, especially for European cars, but has also become a popular bus in industrial automation as well as other applications. The CAN bus is primarily used in embedded systems, and as its name implies, is a network technology that provides [...]
SAE J1939 ECU Simulation And Data Monitoring Under Linux
Our JCOM.J1939.USB gateway board is a high-performance, low-latency vehicle network adapter for SAE J1939 applications. It allows any host device with a USB COM port to monitor SAE J1939 data traffic and communicate with an SAE J1939 vehicle network. The board supports the full SAE J1939 protocol according to J1939/81 Network Management (Address Claiming) and J1939/21 [...]
Non-Contact Rotary Position Sensor With J1939 Output For Vehicle Applications
Curtiss-Wright’s Industrial division has launched the NRH27C, a non-contact rotary position sensor which is suitable for on- and off-highway vehicles utilizing CAN Bus communications. The full range of the digital output span corresponds to a rotation of 360°, and the positional information is determined by the angle of the supplied magnet relative to the sensor body. The maximum [...]
CAN Bus And SAE J1939 Recording and Simulation Using the Raspberry Pi
The Raspberry Pi is a series of small single-board computers developed in the United Kingdom by the Raspberry Pi Foundation to promote the teaching of basic computer science in schools and in developing countries. The original model became far more popular than anticipated, selling outside of its target market for uses such as robotics. Peripherals (including [...]
SAE J1939 Turbo Interface for Raspberry Pi - Firmware Update
The jCOM.J1939.RPi, an SAE J1939 interface for the Raspberry Pi, is not an RPi HAT in the common sense. The board incorporates an ARM processor with CAN transceiver for use on the Raspberry Pi while allowing the operation with any other RPi-compatible board.By combining our J1939 port interface, the Raspberry Pi, an SAE J1939 cable, and [...]
"C" Programming The SAE J1939 Turbo Interface for Raspberry Pi

HMS Introduces IXXAT USB-to-CAN FD (Flexible Data Rate) Gateway
The IXXAT PC interfaces for CAN FD and CAN are typically used for control, monitoring, analysis or configuration purposes. HMS now introduces the IXXAT USB-to-CAN FD — a USB-connected version which is ideal for mobile analysis and configuration. More interface standards will soon be supported, as IXXAT CAN FD versions for Mini PCIe, PCIe 104, XMC and [...]
A Guide To Designing Embedded Hardware And Creating New Computers And Devices
Embedded computer systems literally surround us; they are in our cell phones, PDAs, cars, TVs, refrigerators, heating systems, and more. In fact, embedded systems are one of the most rapidly growing segments of the computer industry today. Along with the growing list of devices for which embedded computer systems are appropriate, interest is growing among [...]
Authentication And Encryption for SAE J1939 And Other CAN Bus Protocols
At the time when the Controller Area Network (CAN) standard was designed, security was not a requirement. The primary usage of the CAN Bus was considered complete; possible intruders or attackers would simply not get physical or remote access to the network. However, today it is more and more common that devices connected to a CAN [...]
The Car Hacker's Handbook For Deeper Understanding Of Embedded Systems In Modern Vehicles
Modern cars are more computerized than ever. Think infotainment and navigation systems, Wi-Fi, automatic software updates, and other innovations that aim to make driving more safe and convenient. However, vehicle technologies haven not kept pace with today's more hostile security environment, which might leave millions of cars vulnerable to attack. The Car Hacker's Handbook will give [...]
