CAN Bus, SAE J1939, NMEA 2000 Programming With ESP32, Supporting USB, Bluetooth, BLE, And WiFi
The ESP32 Series of modules by Espressif supports the integration of WiFi, Bluetooth, and Bluetooth LE for a wide range of applications, most prominently for IoT (Internet of Things). For instance, using WiFi ensures connectivity within a large radius. Using Bluetooth allows the user to easily detect (with low-energy beacons) a module and connect it to [...]
AI Vehicle Computer For Machine Learning, Computer Vision, Sensor Fusion Supports Two CAN Bus Interfaces
Syslogic Industrial Computing introduced its AI railway computer RSL A3 for AI-assisted railroad applications. It comes with two CAN Bus interfaces. The device utilizes the recent Nvidia Jetson AGX Xavier industrial System on Module (SOM), created for challenging environmental conditions. The module features a 512-core Nvidia Volta GPU with 64 Tensor cores, two Nvidia deep learning accelerators, two [...]
The Two Elements of the SAE J1939 Protocol Stack
Any SAE J1939 hardware must support SAE J1939/1x and SAE J1939/21; otherwise, they’re useless because these standards describe the CAN bus physical layer and the basic protocol features. That part is sufficiently covered (i.e., for demonstration purposes) by our CAN shield, while the cabling and connectors may not necessarily J1939-compliant. A fully functional SAE J1939 protocol software [...]
Guide to SAE J1939 - Transport Protocol (TP) Message Packaging and Reassembly
The following is an excerpt from A Comprehensible Guide To J1939 by Wilfried Voss. Certain parameter groups may require more than the eight data bytes supported by the CAN standard. The SAE J1939 standard, namely the Transport Protocol Function, supports message lengths up to 1785 bytes. If a program group requires more than eight data bytes (9…1785 bytes) and [...]
Telematics Gateway For Automatic SAE J1939 and ISOBUS Scanning and Parsing
The CANUp telematics gateway by Technoton couples the functionality of two vehicle data interfaces, a digital-to-analog converter and an online GPS tracking device. The gateway scans and automatically parses 10 000 SAE J1939/71 and ISOBUS parameters and transmits selected data to a web-based telematics server or by email/SMS to a user. It applies edge computing algorithms for onboard [...]
CAN Bus Bolt Connects Industrial Machinery And Devices to Wireless Networks, WiFi And Bluetooth
HMS Networks introduced its Anybus Wireless Bolt CAN gateway, providing CAN Bus communication via WiFi or Bluetooth. The device builds on the success of Anybus Wireless Bolt, which is applied to wireless Ethernet access. Like its predecessor, the gateway for bolt-on-machine mounting is suitable for heavy-duty machinery and demanding industrial applications. Applications include warehouse installations and AGVs (Automated [...]
Programmable Maritime Application System Based on Raspberry Pi Supports NMEA 2000 Functionality
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. GPS status. Steering [...]
Programmable CAN / CAN FD Router And Data Logger Comes With Optional Ethernet Port
The PCAN-Router Pro FD by PEAK-System is a six-channel CAN FD router and data logger, which is now offered with an RJ-45 Ethernet interface as an option. The programmable router comes with custom firmware which is loaded using the CAN Bus network. In addition, the provided development package includes multiple C/C++ programming samples for employing the capabilities [...]
SAE J1939 Data Scanner Monitors Multiple PT1000 Inputs From A Diesel Engine
Axiomatic Technologies introduced their AX184200 20 PT1000 RTD scanner with CAN Bus (SAE J1939) connection. It features rugged packaging and watertight Deutsch IPD connectors for an IP67 rating. The system does not require additional programming or configuration. The scanner monitors 20 2-wire PT1000 inputs from a diesel engine and forwards the temperature information to the engine control [...]
