SAE J1939 250k/500k Baudrate Converter with Arduino Due
The introduction of 500 Kbps (see SAE J1939/14) as an alternative to 250 Kbps, required clarifications on how to solve problems that come with incorporating devices supporting different baud rate settings in the same network. One solution comes with automatic baud rate detection. The SAE J1939/16 document outlines the methods used to detect the baud rate [...]
Programming Thomson Electrac Linear Actuator - Sleep Mode
This post represents an excerpt of Thomson Electrac HD Linear Actuator Motion Control per CAN Bus. The application note is available in eBook and Kindle format, and it includes a free downloadable source code. More Information... In this post, I am explaining the actuator's sleep mode, which, if not fully understood, may cause some headache during the development [...]
Programming Electrac Linear Actuator - ACM, AFM Data Frames
This post represents an excerpt of Thomson Electrac HD Linear Actuator Motion Control per CAN Bus. The application note is available in eBook and Kindle format, and it includes a free downloadable source code. More Information... In this post, I am explaining the Actuator Control Message (ACM) and Actuator Feedback Message (AFM).Thomson Electrac Linear Actuator - ACM Design The [...]
SAE J1939 Display Units for Off-Highway Industrial Engines
The Enginemonitor displays by B-Plus are expansion tools, especially for industrial engines with SAE J1939 interfaces. They enable users to retrieve information from mobile machines and communicate commands directly. Thanks to their robust housings and protection level, the devices can operate directly in the cab and the outdoor area of mobile machines. Due to various device versions, the [...]
LIN Bus Simulation Device Controlled by Windows Software
The Baby-LIN-II by Lipowsky Industrie-Elektronik is a compact system for controlling a LIN BUS network via USB. The PC works as a LIN monitor, LIN Master, or LIN Slave. The system also supports operation in stand-alone mode and allows the execution of continuously running sequences without a PC. In addition, the galvanic isolation guarantees interference-free data transmission. The [...]
ESP32 Development Board Controls Dual Isolated CAN Bus HAT
I am following up on a series of posts I wrote on the topic of connecting an ESP32 processor to Raspberry Pi HATS. The result of this development is the espBerry. The espBerry DevBoard combines the ESP32-DevKitC development board with any Raspberry Pi HAT by connecting to the onboard RPi-compatible 40-pin GPIO header. The purpose of the [...]
Contactless CAN Bus, SAE J1939, OBD-II, SAE J1708 Reader
CAN (J1939) and J1708 networks transport multiple valuable information for telematics of vehicles and stationary objects, such as engine parameters, ABS, EPS, diagnostic codes (DTC), and much more. Crocodile contactless readers are used in telematics systems to gather data from digital buses without breaking the insulation of wires and electrical contacts and without sending active requests [...]
Programmable CAN Bus to USB, Bluetooth, BLE, WiFi Gateway
For the longest time, I had resisted the idea of creating my version of a CAN-to-USB gateway, primarily due to the vast competition. A professional CAN/J1939 development requires a professional CAN-to-PC solution to monitor data traffic. I am pleased with the PEAK PCAN-USB device, as shown in the above image. However, not everybody is willing [...]
Selection Criteria and Requirements for a Telematics Gateway
The March 2023 issue of the CAN Newsletter, a CiA (CAN-in-Automation) online publication, posted an article on the selection criteria and requirements for a Telematics gateway. With cars evolving towards network technologies, OEMs (Original Equipment Manufacturers) require telematics solutions that boost seamless communication within and outside the vehicle. The device should be cloud-enabled, connectable to servers for real-time [...]
PCIe Board with 4-Port Isolated CAN FD for Applications
Sunix (Taiwan) manufactures CAN (FD) interface cards for commercial, agricultural, military, government, recreational, and other industries. Their recently introduced CAN4F00SI PCIe card offers four isolated CAN FD ports. The interface cards can self-diagnose and repair data errors to meet the demand for accurate UAV (Unmanned Aerial Vehicle) control in mission-critical applications. The mission computers, autopilot computers, actuators, [...]
