Kvaser's Leaf v3 Supports Classical CAN and CAN FD in Silent Mode
Every professional CAN Bus development, may it be Classical CAN, CAN FD, or higher layer protocols such as SAE J1939, require a data monitoring device for a proof of functionality. Kvaser has introduced such a device, the Leaf v3 interface supporting Classial CAN and CAN FD in optional Silent Mode. The Leaf series depicts one of the [...]
Dual Isolated CAN Bus PCIe Expansion Card for Industrial, Automotive Applications
Cervoz Technology, a supplier of embedded components for the industrial PC market, has extended its industrial modular expansion cards line with the MEC-CAN-2802i, which provides two isolated CAN CC (Classical CAN) interfaces. The expansion card delivers a cost-effective solution for integrating CAN CC ports into embedded computer systems, especially in hostile environments. The board incorporates an M.2 [...]
Dual-Channel Linear Actuator Control Module with ESP32 Processor
As part of a customer project, I, with the help of a capable hardware designer, developed an embedded system to control two linear actuators, specifically the Thomson Electrac HD model with SAE J1939 interface. The Electrac series of actuators supports two higher-layer protocols (HLP) based on Controller Area Network (CAN): CANopen, and SAE J1939. CANopen is [...]
Industrial Strength Dual CAN FD Interface in Mini PCIe Format
The VL-MPEu-C1 module by Versalogic, compliant with the Mini PCIe format, is a tiny and rugged dual-channel CAN Bus add-on interface. It supports CAN-FD for high-speed data transfer but is still fully compatible with CAN 2.0 A and CAN 2.0 B (Classical CAN). It supports additional CAN functions, including message acceptance filtering, listen-only mode, and wake-up [...]
Micro CANopen Libraries for Embedded CANopen and CANopen FD Higher-Layer Protocols
Embedded Systems Academy (EmSA) announced the release of its Micro CANopen libraries as Open-CMSIS-Pack compliant with the Common Microcontroller Software Interface Standard (CMSIS) by ARM. The release simplifies CANopen implementation in embedded systems. Previously, the Micro CANopen libraries were part of selected NXP MCUXpresso software development kits (SDKs). Along with NXP's recent support release for MS [...]

Know OBD2 Before You Start That Development Project
We at Copperhill Technologies offer a variety of CAN (Controller Area Network) devices for developing automotive and industrial embedded systems. In that capacity, we receive frequent inquiries regarding OBD2 (Onboard Diagnostics). OBD2, or Onboard Diagnostics Second Generation, is a vehicle diagnosis system found in modern cars and trucks. The OBD2 system collects data from sensors and [...]
SAE J1939 250k/500k Baudrate Converter with Arduino Due - Source Code Included
The introduction of 500 Kbps (see SAE J1939/14) as an alternative to 250 Kbps, required clarifications on how to solve problems that come with incorporating devices supporting different baud rate settings in the same network. One solution comes with automatic baud rate detection. The SAE J1939/16 document outlines the methods used to detect the baud rate [...]
