SAE J1939 Programming with Arduino - ARD1939 - J1939 Protocol Stack for Arduino
This post is part of a series about SAE J1939 ECU Programming & Vehicle Bus Simulation with Arduino. The most interesting project in this book is, of course, the fully functional SAE J1939 protocol stack for the Arduino, the ARD1939. ARD1939 supports the full protocol, SAE J1939/21 (Network Management, Address Claim Process) and SAE J1939/81 (Transport Protocol, the transport of messages [...]
SAE J1939 Programming with Arduino - J1939 Data Traffic Monitoring
This post is part of a series about SAE J1939 ECU Programming & Vehicle Bus Simulation with Arduino. In the following Arduino sketch, “data traffic monitoring” means nothing else but receiving and displaying SAE J1939 data messages (Refer also to chapter Receiving J1939 Message Frames). Rather than creating a new project, we will only need to add a few code lines [...]
SAE J1939 Programming with Arduino - J1939 Network Scanner
This post is part of a series about SAE J1939 ECU Programming & Vehicle Bus Simulation with Arduino. Just like the previous project (See chapter Receiving and Responding to J1939 Request Frames) we will be using the SAE J1939 Request Message, in this case to inquire node addresses from the vehicle network. The Request Message (a.k.a. the Request for Address Claimed [...]
SAE J1939 Programming with Arduino - A Simple SAE J1939 to USB Gateway
This post is part of a series about SAE J1939 ECU Programming & Vehicle Bus Simulation with Arduino. I deem it necessary to provide a definition of “SAE J1939 to USB Gateway,” because there are several variants of gateway applications.If you browse through the Internet in search for J1939 gateways, you will primarily find CAN gateways that support the [...]
SAE J1939 Programming with Arduino - Receiving J1939 Message Frames
This post is part of a series about SAE J1939 ECU Programming & Vehicle Bus Simulation with Arduino. This Arduino project provided a bit of a challenge after I had forgotten my own advice.Note: In order to test a CAN/J1939 application, you need at least two CAN/J1939 nodes to establish a network communication. The second node can be another Arduino [...]
SAE J1939 Programming with Arduino - SAE J1939 Monitoring Examples
This post is part of a series about SAE J1939 ECU Programming & Vehicle Bus Simulation with Arduino. The following chapter is primarily about SAE J1939 data monitoring, i.e. the Arduino projects as described work mainly in “Listen-Only” mode. Any bidirectional communication with the vehicle bus requires an SAE J1939 protocol stack implementation, specifically the address claim process. Without a node (source) [...]
SAE J1939 Programming with Arduino - Arduino Code (Sketch)
This post is part of a series about SAE J1939 ECU Programming & Vehicle Bus Simulation with Arduino. The Arduino code is quite simple and virtually self-explanatory. However, let me lose a few words on the program’s structure.First of all, depending on the CAN Bus shield used for this programming sample, please make sure you set the proper CS [...]
SAE J1939 Programming with Arduino - SAE J1939 Monitoring And Simulation
This post is part of a series about SAE J1939 ECU Programming & Vehicle Bus Simulation with Arduino. As I wrote before, both versions of the Arduino used in this book, the Uno and the Mega 2560, are well suitable for SAE J1939 monitoring and simulation projects. Until now, the simulation of SAE J1939 data traffic involved the purchase of expensive [...]
SAE J1939 Applications with the Arduino
This post is part of a series about SAE J1939 ECU Programming & Vehicle Bus Simulation with Arduino. In general, there are three different intentions for connecting to a J1939 vehicle network: Mere monitoring, processing, and display of network data traffic. All functions as described under 1. but extended by [...]
SAE J1939 Programming with Arduino - Message Design
This post is part of a series about SAE J1939 ECU Programming & Vehicle Bus Simulation with Arduino. For this programming sample I have randomly chosen two PGNs from the vast selection of available parameter group numbers. They are: PGN 65267 – Vehicle Position, provides the vehicle’s latitude and longitude. Transmission Repetition [...]
