Controller Area Network Basics: Specification guide book for CAN communication beginners

CAN (Controller Area Network) communication is a message-based communication standard designed to allow microcontrollers or devices to communicate with each other in a vehicle without a host computer. Technically speaking, it is a non-host bus message-based network protocol. CAN is a serial communication consisting of two differential signal lines like RS485 and has the advantage of being simple and inexpensive to implement. It is also suitable for real-time processing and has strong resistance to external electromagnetic waves and noise. Originally composed as a vehicle internal network configuration protocol, CAN has been recognized for its reliability and stability and is now used in industrial automation devices and medical equipment. Because CAN communication is highly reliable and can be implemented at low cost, it is evolving and developing according to the application fields in which it is used, expanding into various sectors such as elevators, building automation, ships, robots, and aerospace.

This book is a commentary on CAN communication protocol that summarizes CAN communication-related matters in one volume. It contains the history and application areas of CAN, protocols related to CAN, and various background knowledge, enabling readers to navigate through various terms such as symbols and codes and to properly understand CAN communication. The book covers a variety of information such as CAN communication frames, error handling, and implementation of the CAN communication system, making it an essential resource for understanding the basics of CAN communication.
