Mini PCI-E Module with Classical CAN, CAN FD, and GNSS
Antzer Tech, a subsidiary of Innodisk, introduced their GADN-FD7L0 PC interface card, which integrates CAN (CAN bus 2.0 a/b, OBDII, SAE J1939), CAN FD, and GNSS features into one mini PCI-E combo module. The board comes in a standard Mini PCI Express form factor. It supports USB 2.0 and two independent CAN FD ports with data-phase bit [...]
ECU and GPS Modules with CAN, CAN FD, SAE J1939 Connections
PEAK-System presented several innovative I/O products with Classical CAN and CAN FD connections in this year's Embedded World trade show. The versatile control unit PCAN-MicroMod FD ECU integrates customer-specific accessories for automotive applications. For this purpose, the device offers a CAN FD connection and a combination of analog and digital I/Os. The I/O processing and message [...]
Telematics Gateway for Real-Time SAE J1939 or ISOBUS Data Monitoring
The CANUp telematics gateway by Technoton measures the operational parameters of vehicles and equipment and reports their performance. The core feature of the CANUp gateway includes the utilization of edge/fog computing methods, which detect 10,000+ possible parameters of vehicle or equipment operation and send generated operation reports to a web-based telematics server and directly to a user via [...]
Compact and Robust Joystick Supports SAE J1939, CANopen Interfaces
Genge & Thoma AG introduced its series of joysticks for industrial and mobile applications with CANopen and SAE J1939 connectivity. The products address applications, including off-road vehicles and vehicle body applications. The SK 60 joystick is a versatile product with several options with various haptic characteristics. The product is available in numerous configurations, with up to three [...]
ESP32 DC Motor PWM Speed Control (Pulse Width Modulation) - The Hidden Facts
Lately, I have worked on two projects requiring DC motor control per PWM (Pulse Width Modulation). What both projects had in common was a profound lack of documentation regarding PWM control, specifically the side effects that have a significant impact on the programming. This post aims to point to these quirks that may cause considerable headaches [...]
Thomson Electrac HD Linear Actuator - Fatal Error Flag at Low Speed
As part of a customer project, I was asked to develop a hardware system to control a linear actuator, specifically the Thomson Electrac HD model with SAE J1939 interface. The Electrac Linear Actuator is a great product, and it is always rewarding to see the application move. Yet, working on this application was, at times, [...]
Thomson Electrak HD Linear Actuator - Multiple Actuators in the Same Network Will Empty the Batteries
Back in April 2022, I published a post, Thomson Electrak Linear Actuator with SAE J1939 Interface for Railway and Industrial Applications intending to use the gained knowledge and publish it in form of an application report. However, after months of working with this product (time frame, not efforts), I still discovered what I call undocumented “oddities.” These [...]
SAE J1939 Diagnostic Device Includes a PGN, SPN Database
The handheld PCAN-Diag FD device from PEAK-System supports diagnosing communication on a CAN (FD) network. In addition, a separately available module extends the functionality to analyze SAE J1939 data traffic. The SAE J1939 Standard describes communication in utility vehicles via CAN Bus. The standard specifies messages and data for transmitting diagnostic and control information using PGNs (Parameter Group Numbers) and [...]
SAE J1939 - Simulation of Request Message with J1939 to USB Gateway
The above image shows my SAE J1939 test setup with three nodes connected through our CAN-Bus Hub with 7 Ports and DC Power Connection. They are: SAE J1939 to USB Gateway in Plastic Enclosure... SAE J1939 ECU Simulator Board With USB Port... PEAK PCAN-USB Pro FD - CAN, CAN FD, and LIN Interface for High-Speed USB 2.0... The PCAN-USB [...]
SAE J1939: Simulation of Analog and Digital Signals with the JCOM1939 Monitor Software
The JCOM1939 Monitor Software is ideal for monitoring, recording, analyzing, and simulating SAE J1939 data traffic. The system works in combination with our SAE J1939 gateways. This comprehensive and easy-to-use, easy-to-understand Windows software displays not only SAE J1939 data traffic but also scans the network, simulates an ECU (incl. full node address negotiation features), and responds [...]
