Smarter Connections: The CAN Interface Revolution
Abstract
This whitepaper provides an overview of the CAN interface (Controller Area Network) bus system, which was developed to simplify and improve communication between electronic components in vehicles. Originally introduced by Bosch in the 1980s, CAN has become the standard for efficient data exchange in cars, trucks, and various industrial applications. The paper explains the basic principles of CAN, its advantages in reducing cabling complexity and vehicle weight, and explores the protocols used for communication.
Moreover, you will find out:
- How does a CAN bus work?
- What are the differences between CAN and CAN-FD?
- What is the CAN bit timing logic (BTL)?
- How does the CAN interface communication work?
- What is J1939?
- How to receive or transmit data via a CAN bus with a DEWETRON data acquisition system?
