Any CAN Bus, SAE J1939, NMEA 2000 Development Requires the Right Testing Tools
I want to reiterate a point made in a previous post ("A Beginner's Guide to SAE J1939 Embedded Software Development"): When developing and testing your CAN Bus application, may it be Classical CAN, CAN FD, CANopen, SAE J1939, or NMEA 2000, you need to connect your device to a functional network. One solitary node connected to your [...]
Data Acquisition from Heavy Duty Vehicles Using SAE J1939 CAN Bus
Modern vehicles have electronic control units (ECUs) to control various subsystems such as the engine, brakes, steering, air conditioning, and infotainment. These ECUs (or ‘controllers’) are networked to convey information and output measured and calculated data to each other.This in-vehicle network is a data goldmine for improved maintenance, measuring vehicle performance and its subsystems, fleet [...]
NMEA 2000 / SAE J1939 Data Scanner with BLE Interface for iOS Applications
This post is a follow-up on NMEA 2000 Data Scanner with Bluetooth, BLE for Android, iOS, PC Applications. In this new post, I also include SAE J1939, since NMEA 2000 is based on J1939. Also, in this particular case, instead of the NMEA2000-compatible 5-pin M12 connector, I used a DSUB9, which applies to the CAN Bus and [...]
NMEA 2000 Data Scanner with Bluetooth, BLE for Android, iOS, PC Applications
Our N2K-BT gateway functions as a NMEA 2000 to Bluetooth data scanner for any host device with a Bluetooth or BLE (Bluetooth Low Energy) port, such as PCs, phones, or tablets. Therefore, it supports operating systems such as Windows, Linux, iOS, Android, and more. In addition, the wireless communication protocol employs easy-to-read and easy-to-process ASCII [...]
Agricultural Control Unit Supports Isobus, SAE J1939, and CANopen Connectivity
The EC44 Agri control unit by Epec (Finnland) supports Isobus communication for agriculture applications. In addition, the device can upgrade existing systems to Isobus connectivity when used as a gateway. The Isobus-compliant device allows plug-and-play compatibility between tractors and other agricultural equipment (e.g., seeders or fertilizers) from different manufacturers and brands. Legacy implementations operated via customized human-machine interfaces (HMI), i.e., [...]
SAE J1939 Enabled Temperature Scanner Monitor up to 20 Thermocouples and Two RTDs
Axiomatic, a designer and manufacturer of electronic controllers and power management converters, introduced their AX180800 temperature scanner that monitors up to 20 thermocouples and two RTDs. The device features two SAE J1939 interfaces. The channels are independently configurable as Type J, K, B, E, N, R, S or T thermocouples, measuring exhaust, winding, and fluid temperature. All temperature data are [...]
ESP32 Based CAN Bus, SAE J1939 and NMEA 2000 to Bluetooth Gateway
The following is a follow-up on our post Controller Area Network (CAN), SAE J1939, NMEA 2000 Wireless Module for IoT and ELD Applications. The CAN Bus, SAE J1939 and NMEA 2000 to Bluetooth Gateway is the first product of a new series of wireless gateways for IoT (Internet of Things), ELD (Electronic Logging Devices), and other applications. At the [...]
Controller Area Network (CAN), SAE J1939, NMEA 2000 Wireless Module for IoT and ELD Applications
Due to the global shortage of electronic components, we at Copperhill Technologies began rethinking our strategy regarding new developments. Luckily, that change turned out to be a blessing in disguise because the transition from NXP LPC to the ESP32 processor opened the door to more industrial and automotive applications, especially those involving wireless transmissions for [...]
Thomson Electrak Linear Actuator with SAE J1939 Interface for Railway and Industrial Applications
For many years I maintained the view that the SAE J1939 protocol, specifically its advanced network management capabilities, provides many great features to support any industrial application. SAE J1939 is an ingeniously designed protocol with very little protocol overhead, requiring only a minimal memory footprint that benefits the use of small embedded systems. I am now [...]
CAN Bus Analysis Software Supports SAE J1939 and CANopen Data Monitoring and Recording
The CANexplorer 4 by Sontheim is a modular, efficient, and intuitive field-bus analyzing software. It represents years of experience working with complex machine and vehicle CAN Bus networks. The modular structure delivers all critical features for analyzing and logging CAN Bus network traffic, like classic text-based traces, graphs, bar graphs, LEDs, filters, and triggers. Furthermore, the software [...]
