CAN Bus Interface For the Raspberry Pi 2/3 Comes With Various Options
The PiCAN2 board series by Copperhill Technologies provides CAN Bus capabilities for the Raspberry Pi 2 or 3. The boards (with the exception of the dual isolated interface) use the Microchip MCP2515 CAN controller in combination with the MCP2551 CAN transceiver. There is an easy to install SocketCAN driver, and programming can be accomplished in C [...]
CAN Bus Data Traffic Simulation With Arduino Due
When working on a CAN bus or SAE J1939 project, it can be extremely helpful when the expected CAN Bus data traffic can be simulated rather than connecting your system to a running vehicle or automation control. The following project does exactly that with little effort for designing CAN data frames and their frequency. As [...]
SAE J1939 to USB Gateway Allows Easy Communication And Analysis Of Truck, Bus Network
The SAE J1939 ECU Simulator Board With USB Port by Copperhill Technologies provides a powerful, yet easy-to-manage connection to a J1939 network, allowing the reception, monitoring & analysis, and transmission of PGNs (Parameter Group Numbers) as defined by the SAE J1939-71 Standard. The gateway supports the full SAE J1939 Standard, including Network Management (Address Claim, SAE J1939/81) and [...]
How To Use The Native USB Of The Arduino Due For High-Speed Communication
It seems to be an obvious statement, but there are many applications for the Arduino Due that require high-speed communication in a range that goes beyond regular UART baud rates, i.e. several Mbits/sec. Naturally, USB comes to mind, but surprisingly there are some obstacles when it comes to accessing the Arduino Due's USB ports. The [...]
Bosch Automotive Electrics and Automotive Electronics: Systems and Components, Networking and Hybrid Drive
This book represents a complete reference guide to automotive electrics and electronics. This new edition is the definitive reference for all automotive engineers, and it has been compiled by one of the world's largest automotive equipment suppliers, the Robert Bosch GmbH. The book also includes new and updated material.As in previous editions, the various topics [...]
SAE J1939 Project With Arduino Uno/Mega2560: Requesting & Simulating Vehicle Identification Number (VIN)
This post describes an Arduino project (sketch) that requests the Vehicle Identification Number (VIN) from an SAE J1939 vehicle network. Before I go into the technical details, let me describe the hardware configuration. First, as shown in the picture, I used an Arduino Uno with a CAN Bus Shield. In order to simulate the SAE J1939 vehicle bus, [...]
Dual CAN Bus Interface For Arduino Due: Controlling the LEDs
The following explains how to control the LEDs on our jCOM.CAN.DUE and jCOM.CAN.DUE-X boards. The experienced Arduino programmer may frown since all necessary information is available (LED1 = GPIO 14; LED2 = GPIO 15). Consequently, this post is for the novice Arduino programmer or those who are primarily interested in embedded Controller Area Network programming. Just as a reminder, [...]
Arduino Due: Dual CAN Port Test Sketch With LED CAN Traffic Indicators
In a previous post ( Arduino Due: Dual CAN Port Test Sketch), I demonstrated how to read and write the two CAN ports on the Arduino Due. The post explains that the two CAN ports on the Arduino Due are practically useless without their respective CAN transceivers. CAN transceivers convert a regular TTL signal from the CAN controller [...]
Arduino Due: Dual CAN Port Test Sketch
Let me, first of all, stress the point that the two CAN ports on the Arduino Due are practically useless without their respective CAN transceivers. CAN transceivers convert a regular TTL signal from the CAN controller into a differential voltage, which in turn contributes to the vast reliability of a Controller Area Network. For more [...]
Development Of Microcontroller-Based Projects Using The CAN (Controller Area Network) Bus
Controller Area Network (CAN) was originally developed for use as a vehicle data bus system in passenger cars. Today, CAN controllers are available from over 20 manufacturers, and CAN is finding applications in numerous other fields, such as medical, aerospace, process control, automation, and more. This book, Controller Area Network Projects, was written for students, practicing [...]
