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, [...]
Programming the SAE J1939 ECU Simulator Board Using Visual Studio C#
The following refers to a Visual Studio C# application, representing a very simplified version of our jCOM1939 Monitor - SAE J1939 Monitor, Analyzer, And ECU Simulator. The jCOM1939 Monitor Software is a tool to monitor, analyze, and simulate SAE J1939 data traffic. The system combines our jCOM.J1939.USB that functions as an SAE J1939 to USB (or UART) [...]
SAE J1939 Protocol Stack Sketch for Arduino Due
The availability of Controller Area Network (CAN) interfaces in combination with other interface technologies explains the vast popularity of the ARM Cortex-M3 processor in the CAN and SAE J1939 industry. The processor provides the means to easily and quickly create applications like CAN/J1939 gateways, CAN Bridges, J1939 ECUs, J1939 Data Logger, and many more. The Arduino Due [...]
