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 [...]
Building Arduino-Based Projects For The Internet Of Things (IoT)
The IoT: Building Arduino-Based Projects course takes you on a journey to become an expert in the use of IoT by developing a set of projects, and it leads you through securing your IoT environment.In the first module, Learning Internet of Things, you learn how protocols and patterns can put constraints on network topology. You also learn [...]
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 [...]
Wireless Internet of Things (IoT) Starter Kit With GPS & GSM Monitors Fill Levels
Pepperl+Fuchs introduced a level sensor that transmits its data to a secure remote station in the industrial Internet of Things. The IoT sensor WILSEN.sonic.level comes with a bundle that includes a starter package with the WILSEN.service and a business data platform, which allows users to determine the value of the IoT system for their application. With the [...]
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 [...]
Fanless Embedded Intel Core & Celeron System with CAN Bus and CANopen Option
The eBOX700-891‑FL from Axiomtek is a fanless embedded system with numerous expansion options. It reserves space for additional CAN Bus or CANopen modules.The embedded system supports dual DDR4-2133 SO-DIMM slots with up to 32 GiB system memory, and it is suited for vision inspection (USB/PoE), motion control, security surveillance, and industrial automation. The box PC is powered [...]
