Programmable SAE J1939 Analog Signal Output Controller
The 4 Analog Signal Output CAN Bus Controller by Axiomatic extends machine control networks by adding I/O control to the CAN Bus. Diesel engine control systems with SAE J1939 can communicate with 4-20 mA or other analog signal input devices using this controller as a smart interface. The controller can be configured to accommodate a particular application utilizing [...]
CANopen Architect Software For Creating And Editing Electronic Data Sheets (EDS)
CANopen is a higher layer protocol operating on a CAN Bus network. The CAN Bus specification defines solely the physical and data link layers in the ISO/OSI 7-layer Reference Model. Consequently, only the physical bus and the CAN Bus message format is defined, but not how the CAN Bus message applies. CANopen provides an open and [...]
SAE J1939 Simulator Generates Frequently Used SAE J1939 Signals (PGNs) For Diesel Engines
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 valuable [...]
CANopen Library For Linux Based Application Development
The CANopen Magic Pro Library by Embedded Systems Academy is a system supporting customized CANopen based PC applications for quick and easy development without the need to know all details of the CANopen protocol stack. The kit consists of a professional CANopen library along with documentation, a C header file and makefile for gcc. The CANopen library achieves [...]
SAE J1939 And CAN Bus Display Gauges For Off-Road And On-Road Vehicles
Veethree Technologie (UK) offers a range of CAN Bus and SAE J1939 LCD display gauges. The range of gauges directly wires to an SAE J1939 compliant CAN Bus without needing another device to drive them. Compact and easy to install, the gauges are available in 2″ & 3" sizes, in conventional black or white dial colors with chrome [...]
SAE J1939 vs. CAN Bus - Physical Layer And Higher Layer Protocol (HLP)
To answer the fundamental question upfront: SAE J1939 is a higher-layer protocol (i.e., an add-on software) that uses the CAN Bus technology as a physical layer. In addition to the standard CAN Bus capabilities, SAE J1939 supports node addresses, and it can deliver data frames longer than 8 bytes (in fact, up to 1785 bytes). However, [...]
Repeaters for CAN Bus, CAN FD And CAN-Based Higher Layer Protocols Such As CANopen And SAE J1939
Adding to the current IXXAT line of CAN bridges and gateways, HMS Networks launched four Ixxat CAN FD repeaters, all supporting both the new CAN FD standard as well as traditional CAN Bus.With the IXXAT CAN FD repeaters, HMS allows the networking of existing CAN Bus systems as well as in CAN FD-based systems.The repeaters enable CAN FD (CAN [...]
Low-Cost Do-It-Yourself CAN Bus To WiFi, Bluetooth, BLE, USB, RS485 Gateway Based On Raspberry Pi Zero
In the following, I will discuss a do-it-yourself project utilizing the Raspberry Pi Zero in combination with the CAN Bus Plus RS485 HAT. The combination of serial and wireless ports provided by this system allows the development of a great number of gateway applications. Overall, this small-size hardware includes connections such as CAN Bus, RS485, [...]
Electronic Logging Device Concept: Small Form-Factor ELD Based On Raspberry Pi With CAN Bus Port And GSM/GPRS/GNSS Support
An electronic logging device (ELD) is an electronic hardware that is attached to a commercial motor vehicle engine to record driving hours. The driving hours of commercial drivers (truck and bus drivers) are regulated by a set of rules known as the hours of service (HOS). The Commercial Vehicle Driver Hours of Service Regulations vary in Canada [...]
Easy Integration Of CANopen Or SAE J1939 Protocol Stack Into Any Embedded System With Serial Input
The simple assumption behind the statement of easy integration of a CANopen or SAE J1939 protocol stack is that virtually every embedded system (and even other industrial controls such as PLCs) do have a serial port of some sort, mostly UART, RS232, or USB. "Easy" also implies that you don't have to go through major [...]
