Controller Area Network
Controller Area Network (CAN) is a robust vehicle bus standard designed to allow microcontrollers and devices to communicate with each other's applications without a host computer. It is a serial communication protocol that was originally developed for automotive applications, but has since been used in various industrial automation, medical equipment, and aerospace industries. CAN enables reliable data transfer between different electronic control units (ECUs) in vehicles, allowing them to share information such as speed, engine temperature, and braking status. It operates on a single twisted-pair wire and uses differential signaling, which helps it withstand electrical noise and interference. CAN messages are prioritized based on their identifiers, ensuring that critical data is transmitted first and reducing the risk of collisions. Overall, CAN facilitates the integration and coordination of various electronic systems within complex devices and machines, improving their functionality, efficiency, and safety.
