CAN FD Controller With Integrated CAN Transceiver And SPI Interface

Texas Instruments has introduced their TCAN4550, a CAN FD stand-alone controller with integrated (on-chip) transceiver. The TCAN4550 represents an interface between a CAN Bus network and a host controller through a serial peripheral interface (18-MHz SPI).It supports the Classical CAN and the CAN FD data link layer. In addition, the chip comes with CAN FD transceiver functionality: differential [...]

ELD Concept: SAE J1939 Data Recording And Display Using Android Or iOS Devices

An electronic logging device (ELD) is 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 and [...]

Controller Area Network (CAN Bus) - Physical Layer And Bus Topology

The following is an excerpt from  A Comprehensible Controller Area Network by Wilfried Voss. The ISO/OSI Reference Model specifies seven levels starting with the physical connection up to the actual user application, i.e., the Application Layer. The standard CAN Bus implementation neglects the connection between the Data Link Layer and the Application Layer to save on relevant memory resources [...]

CAN Bus Over Ethernet Interface For Internet-of-Things (IoT) Applications

The EtherCAN HS by Kvaser is a real-time Ethernet-to-CAN gateway interface that, when connected over the Internet to an Ethernet-equipped PC, enables remote CAN Bus data access from anywhere in the world. The built-in Power-over-Ethernet eradicates the requirement for a separate power cable when it is not possible to power the device from the CAN Bus network. Kvaser's EtherCAN [...]

Galvanically Isolated CAN Bus Transceivers Protect Networks Against Destructive Energy

High noise levels on a CAN bus network have the potential to destroy CAN bus transceivers. This noise originates mainly from two sources, ground loops and electrical line surges.Protecting a network against this destructive energy requires the galvanic isolation of the CAN bus system from other local node circuitry. For more information on Controller Area [...]

SAE J1939 Address Management Messages (Address Claim PGNs)

The following is an excerpt from  A Comprehensible Guide To J1939 by Wilfried Voss. According to  SAE J1939/81, network management procedures are used to “collectively manage the network”.While other higher layer protocols based on CAN Bus do not support dynamic node address assignments per default, the SAE J1939 standard provides yet another ingeniously designed feature to uniquely identify ECUs [...]
