JCOM1939 Monitor Software - A Critical SAE J1939 Diagnostic and Analysis Tool
The JCOM1939 Monitor Software is a specialized tool designed to interface with and monitor data on the SAE J1939 communication network. SAE J1939 is a standardized protocol commonly used in heavy-duty vehicles, agriculture equipment, and industrial machinery for onboard diagnostics and data communication. This essay explores the features, applications, and significance of JCOM1939 Monitor Software in [...]
Improvements to our JCOM1939 Monitor & Simulation Software for Windows
Our SAE J1939 gateways are steadily gaining popularity, so we developed a dedicated website that focuses on the associated JCOM1939 Monitor Software for Windows. Since July of this year, we have added new features, some small and some significant improvements.With version 3.50.00, we have ceased support for older gateways, specifically those sold before 2022. The processors in [...]
Impact of Cybersecurity Regulations on CAN Bus Embedded Development
Across the globe, regulatory bodies issue rules and regulations related to the cybersecurity of electronic devices. Among the strictest are those from the EU, including the Cybersecurity Act (CSA) and the Cyber Resilience Act (CRA), which all manufacturers of electronic embedded network devices are required to follow. While some manufacturers may temporarily avoid adopting a “security [...]
OBD2 Bluetooth Scanner for iPhone, Android, and Windows
The OBDLink MX+ is a unique wireless OBD adapter that transforms any iPhone, iPad, or Android device into a professional-grade diagnostic scan tool, trip computer, and real-time performance monitor capable of accessing manufacturer-specific vehicle data. The newest addition to the OBDLink family is even faster, more reliable, and features richer than its predecessors. It is the only wireless [...]
OBD2 Bluetooth Scanner with App for iOS & Android
The V011 OBD2 Scanner provides a complete diagnostic solution, thoroughly understanding your vehicle's condition. It supports a variety of performance tests, including fast reading of DTCs, access to electronic emission readiness, turning off the CEL or MIL, resetting monitors, reading live data, retrieving the vehicle's VIN, checking battery health, accessing freeze frame data, reviewing sensor data, [...]
ESP32 Processor: CAN Bus Topology and Termination Resistors
This post is an excerpt from our application note Controller Area Network (CAN) Development with ESP32. It is my experience that newcomers to the technology overlook the importance of termination resistors. Missing or misplaced resistors can lead to transmission errors or even prevent transmission altogether. The general rule is that if you connect to an existing, fully [...]
Python Code Example for CANgineBerry’s CANopen Manager
Embedded Systems Academy has released a new software update for the CANgineBerry. This update includes a Python example designed to streamline network management for developers using Linux, Windows, and macOS. The example utilizes the provided CANopen Manager firmware to visualize and efficiently manage devices on a CANopen network. The CANgineBerry goes beyond basic CAN interfaces by handling [...]
ESP32 Development Kits with Onboard CAN Bus Controller
The ESP32 is a low-cost, low-power system-on-chip microcontroller with integrated WiFi and dual-mode Bluetooth. It is equipped with a Tensilica Xtensa LX6 microprocessor in dual-core and single-core versions. The microcontroller features built-in antenna switches, RF balun, power amplifiers, low-noise receive amplifiers, filters, and power management modules. It is the successor to the ESP8266 SoC. There are [...]
ESP32 Processor: Internal SJA 100 CAN Bus Controller
This post is an excerpt from our application note Controller Area Network (CAN) Development with ESP32.The ESP32 integrates a CAN Bus controller compatible with the NXP SJA1000. Thus, it is CAN 2.0B (ISO 11898, a.k.a. Classical CAN) specification-compliant.As with the SJA1000, the ESP32 CAN Bus controller provides only the data link layer and the physical layer [...]
ESP32 Processor: Adding a CAN Bus Transceiver
This post is an excerpt from our application note Controller Area Network (CAN) Development with ESP32.As a quick reference, I want to address the need for a CAN transceiver. As mentioned in the previous chapter, the ESP32 has an internal CAN Bus controller. However, this doesn't mean you can directly connect it to a network. You [...]
