Data Acquisition from HD Vehicles Using The SAE J1939 CAN Bus
Modern vehicles are equipped with electronic control units (ECUs) to control various subsystems such as the engine, brakes, steering, air conditioning, and infotainment. These ECUs (Electronic Control Units) are networked to share information, and output directly measured and calculated data. The SAE J1939 in-vehicle network is a data goldmine for enhanced maintenance, measuring vehicle performance and its [...]
LIN Bus Serial Analyzer Development Tool For Automotive Applications
The LIN Serial Analyzer development tool enables the user to monitor and communicate to a LIN (Local Interface Network) bus using a Personal Computer (PC). It is a powerful tool that can be used to send messages, monitoring the bus traffic, perform error checks, and filter messages. There are many other features, allowing the user to [...]
SAE J1939/13 Off-Board Diagnostic Connector Deutsch HD10-9–1939
The SAE J1939/13 document defines a standard connector for diagnostic purpose. The connector is a Deutsch HD10 - 9 – 1939 (9 pins, round connector). According to the document, the connector supports both the twisted shielded pair media (as defined in SAE J1939/11) as well as the twisted unshielded quad media (as defined by ISO 11783-2). The designations [...]
ARM Cortex M4 Single-Chip MCU Supports CAN Bus, USB, Bluetooth for IoT And Gateway Applications
Renesas introduced its RA4W1, an MCU with an integrated CAN Bus, USB, and Bluetooth 5.0 Low Energy (BLE). The single-chip MCU includes a 48 MHz, 32-bit Arm Cortex-M4 core, and Bluetooth 5.0 core delivered in a 56-pin QFN package.The MCU enables designers of embedded systems to develop IoT (Internet of Things) endpoint devices for Industry 4.0, [...]
SAE J1939/16 Automatic Baud Rate Detection Process
The SAE J1939/16 document outlines the methods used to detect the baud rate of an SAE J1939 network segment by ECUs that can adjust their CAN baud rate while in use. The specified approach provides a reliable method to detect the CAN baud rate of that network segment without interrupting network communications. SAE J1939/16 defines the following requirements [...]
Single-Board ARM i.MX6 Computer Supports CAN Bus, WiFi, And Bluetooth
Versalogic introduced its Swordtail VL-EPC-2702 as part of a product series of ARM‑based embedded computers. It comes with an ISO 11898‑2‑compliant CAN Bus interface, which supports the 29-bit identifier extended frame format (CAN 2.0B) for SAE J1939 applications.Available with either the NXP i.MX6 Quad (quad-core), or the i.MX6 Duallite (dual-core) processors, the board carries an onboard Wi‑Fi, Bluetooth, [...]
SAE J1939 And The Challenging Migration From Classical CAN To CAN FD and CAN XL
The Society of Automotive Engineers (SAE) Truck and Bus Control and Communications Subcommittee has developed a family of standards concerning the design and use of devices that transmit electronic signals and control information among vehicle components. SAE J1939 and its companion documents have quickly become the accepted industry standard and the vehicle network of choice for off-highway [...]
Embedded ARM Cortex-A35 Modules With Up To Three CAN FD Interfaces
TQ-Systems (Germany) introduced their TQMa8xx and TQMa8xxs embedded modules that feature three, and respectively two CAN FD interfaces. The TQMa8xx module offers integrated graphics, a DSP (Digital Signal Processor) for audio processing, and security-related functions. To meet various requirements, three CPU (Central Processing Unit) alternatives with a dual-core or quad-core ARM Cortex-A35 processor are available. Each core supports a [...]
Introduction To The NMEA 2000 Marine Networking Standard
NMEA 2000 is a marine networking standard created and administered by the National Marine Electronics Association (NMEA). The NMEA is an association of marine electronics manufacturers, dealers, and technicians. The NMEA 2000 standard describes a low-cost, moderate capacity, bi-directional, multi-transmitter, multi-receiver instrument network. Typical data on a network using this standard include position latitude and longitude, [...]
