Design Of Proprietary Parameter Group Numbers (PGNs)
For a brief introduction to PGNs, see our post SAE J1939 Message Format and Interpretations of PGNs.As the name Proprietary Parameter Group Numbers implies, the SAE J1939 standard supports Parameter Groups in PDU1 and PDU2 Format that manufacturers can assign for their specific needs, which includes the design of the data field in the message. [...]
SAE J1939 Data Traffic Generator For Diesel Engine Network Simulation
I am writing this post in response to multiple inquiries from newcomers to the SAE J1939 technology. Most questions are in the nature of "Can your device simulate any PGN, for instance, engine speed in rpm?" or "Can your device simulate a 2014 Tonka Flex diesel engine?" The short answer is yes, but things are [...]
Four Channel CAN Bus to USB Gateway Using The Arduino Due
In the past, I frequently received inquiries regarding the availability of a four-channel CAN Bus gateway. Such devices exist in the marketplace; however, they are usually costly, and, after all, they don't support easy customization or programming. While we at Copperhill Technologies have the ability to create such a gateway, this is primarily a matter [...]
Arduino-Due-Based SAE J1939 Programming Kit - Quick Start Reference
Unleash the power of the Arduino Due with ARM Cortex-M3 processor to develop and test your SAE J1939 application, may it be an SAE J1939 to USB protocol converter, an SAE J1939 Bridge, an SAE J1939 data monitor, and many more. The SAE J1939 Programming Kit comes with many programming samples, including a full-blown SAE J1939 [...]
Testing NMEA 0183 For The PICAN-M - NMEA 0183 & NMEA 2000 HAT For Raspberry Pi
PICAN-M - NMEA 0183 & NMEA 2000 HAT For Raspberry Pi Our PICAN-M (M = Marine) is a Raspberry Pi HAT with NMEA 0183 and NMEA 2000 connection. The NMEA 0183 (RS422) port is accessible via a 5-way screw terminal. The NMEA 2000 port is accessible via a Micro-C connector. The board comes with a 3A SMPS (Switch [...]
Embedded ARM Modules For IoT Applications Support Two CAN FD Ports
The TQMax4xxl modules by TQ Systems represent an LGA (Land Grid Array) based on the Sitara AM243x microcontroller and the AM64xx processor with up to six cores from Texas Instruments. Possible applications include servo motor controllers (for robotics), industrial gateways, data collectors, and small edge servers in production, providing data for the cloud. The module size of [...]
Wireless IoT Project Development with the ESP32
The ESP32 represents a low-cost, low-power System-on-Chip (SoC) microcontroller with integrated Wi-Fi and dual-mode Bluetooth. The ESP32 series utilizes either a Tensilica Xtensa LX6 microprocessor in dual-core and single-core variations, Xtensa LX7 dual-core microprocessor, or a single-core RISC-V microprocessor and includes built-in antenna switches, RF balun, power amplifier, low-noise receive amplifier, filters, and power management [...]
Advanced IoT Programming Using The Raspberry Pi 4 And Python 3
Python is an interpreted, object-oriented, high-level programming language with dynamic semantics. Its high-level built-in data structures, combined with dynamic typing and dynamic binding, made it very attractive for Rapid Application Development. It is used as a scripting or glue language to connect existing components. Python's simple, easy-to-learn syntax emphasizes readability and therefore reduces the cost of [...]
SAE J1939 250k/500k Baudrate Converter Using Arduino Due With Dual CAN Bus Port
In the past months, customers have approached me regarding a CAN Bus baud rate converter for SAE J1939 networks. The original SAE J1939 Standards Collection was limited to a baud rate of 250k, basically to keep things simple and reliable. I don't know what triggered the decision to add the additional 500k baud rate. From [...]
SAE J1939 Protocol Converter Supports Modbus And Ethernet Connectivity
Axiomatic Technologies announced the release of their AX141810, a Modbus router with CAN Bus and Ethernet connectivity. It is available in two variants. The protocol converter is user-configurable via a web browser, featuring data exchange between a CAN Bus network, specifically SAE J1939, EIA-485, and Ethernet.The unit integrates one isolated extended frame format CAN Bus interface, [...]
