Arduino Breakout Board Connects Classic CAN Bus and CAN FD Networks
Many users involved with CAN Bus programming (and exploring the extended capabilities of CAN FD) may not be aware that Classic CAN Bus and CAN FD are excluding each other due to compatibility issues. For more detailed information, see our post CAN FD On A Legacy CAN Bus Network Is Not A Good Idea Due To [...]
RobotDyn - Data Logger Shield For Arduino - Development Resources
To mention it upfront, we don't sell the data logger shield for the Arduino. As a matter of fact, I bought this board out of pure curiosity, because it fits and complements our Arduino-Based ECU Development Board With Dual CAN Bus Interface. This combination bares the potential for creating a low-price CAN Bus data logger.I was [...]
CAN Bus Router Connects Classic CAN And CAN FD Networks And Operates As A CAN Bus Recorder
PEAK-System Technik has extended its product range with its programmable PCAN-Router Pro FD, which connects the data traffic of up to six CAN FD or classic CAN Bus networks. The routing from CAN Bus to CAN FD or vice versa enables the integration of new CAN FD applications into existing CAN 2.0 systems.Note: Classic CAN Bus [...]
Tablet PC For In-Vehicle Networks Supports CAN Bus - SAE J1939 And Gigabit Ethernet Interfaces For IoT Applications
The X7R from Waysion Technology (China) is a 7-inch tablet PC designed to operate within truck in-cab and other applications within harsh environments.A CAN Bus interface maintains data communications via an extension cable, and it supports the 29-bit CAN-identifier. If required, the SAE J1939 higher-layer protocol can be implemented using an additional converter. The device receives data from CAN [...]
Control Unit With Two CAN Bus Ports Supports CoDeSys Programming
Epec has released the Ec44 control unit, representing a new member of the Epec product. The controller comes in a new enclosure and a 46-pin Leavyseal connector with lever locking. The controller has a powerful 32-bit processor and large internal memory for application and parameters, two CAN Bus ports, Codesys 3.5 programming, and 16 inputs and outputs. The [...]
The Difference Between SAE J1939 And CAN Bus - The Extended CAN Bus Protocol
The following is an excerpt from A Comprehensible Controller Area Network by Wilfried Voss. The standard CAN message frame uses an 11-bit message identifier (CAN 2.0A), which is sufficient for the use in regular automobiles and any industrial application, however, not necessarily for off-road vehicles.The Society of Automotive Engineers (SAE) Truck and Bus Control and Communications Subcommittee [...]
JCOM1939 Monitor Software - New Version 3.31.00
Our SAE J1939 ECU Simulator Board With USB Port allows any host device (e.g., PC) with a USB COM port to monitor SAE J1939 data traffic and communicate with the SAE J1939 vehicle network, which makes it also suitable to simulate SAE J1939 data traffic. The simulation of SAE J1939 signals (i.e., PGNs) is a [...]
SAE J1939 Data Monitoring And Simulation With The Arduino
The following is an excerpt from SAE J1939 ECU Programming & Vehicle Bus Simulation with Arduino by Wilfried Voss 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 the ability of sending data into the J1939 [...]
Controller Area Network (CAN Bus) - Error Detection And Fault Confinement
The following is an excerpt from A Comprehensible Controller Area Network by Wilfried Voss. The CAN standard utilizes a series of error detection mechanisms, which contribute to its high level of reliability and error resistance (see following Chapter - Error Detection). The reliability of CAN has been calculated in a mathematical model. Here is an example using the following [...]
SAE J1939 Transport Protocol (TP) Functions
The following is an excerpt from A Comprehensible Guide To J1939 by Wilfried Voss. Even though extremely useful in passenger cars and small industrial applications, CAN alone was not suitable to meet the requirements of truck and bus communications, mainly since its communication between devices is limited to only 8 bytes per message. However, it is possible [...]
