A controller area network (CAN) is a vehicle bus standard designed to enable efficient communication primarily between electronic control units (ECUs). Originally developed to reduce the complexity and cost of electrical wiring in automobiles through multiplexing, the CAN bus protocol has since been adopted in various other contexts.
Node Service Interface: As an enhancement to CAN, CANaerospace provides a means for individual stations on the network to communicate with each other using connection-oriented and connectionless services. Predefined CAN Identifier Assignment: CANaerospace offers a predefined identifier assignment list for normal operation data. In addition to ...
Mule is a lightweight enterprise service bus (ESB) and integration framework [1] provided by MuleSoft.It has a Java-based platform and can also act as broker for interactions between other platforms such as .NET using web services or sockets.
SocketCAN is a set of open source CAN drivers and a networking stack contributed by Volkswagen Research to the Linux kernel. SocketCAN was formerly known as Low Level CAN Framework (LLCF). Typical CAN communication layers. With SocketCAN (left) or conventional (right). Traditional CAN drivers for Linux are based on the model of character devices.
CANpie (CAN Programming Interface Environment) is an open source project and pursues the objective of creating and establishing an open and standardized software API for access to the CAN bus. CANpie FD logo. The project was established in 2001 [1] by MicroControl and is licensed under Apache License version 2.0.
Using this file descriptor standard operating system functions like read() and write() are used to exchange CAN frames with other CAN nodes on a CAN bus. The following code is an example which puts a CAN frame on the bus and afterwards waits for a CAN frame transmitted by another CAN node. More examples are available on the can4linux project ...
The first RFC broadly outlining the general ideas that would later form the core design principles of Cyphal (branded UAVCAN at the time) was published in early 2014. [4] It was a response to the perceived lack of adequate technology that could facilitate robust real-time intra-vehicular data exchange between distributed components of modern intelligent vehicles (primarily unmanned aircraft).
In CANopen the 11-bit id of a CAN-frame is known as communication object identifier, or COB-ID. In case of a transmission collision, the bus arbitration used in the CAN bus allows the frame with the smallest id to be transmitted first and without a delay. Using a low code number for time critical functions ensures the lowest possible delay.
