CAN Protocol Complete Course Roadmap: Zero to Hero 🚗

Course Overview

The presenter outlines a six-chapter course that teaches CAN protocol, from introductory concepts to practical and advanced topics. The course aims not only to explain how CAN works, but also to help learners diagnose, test, and troubleshoot CAN systems.

Course Roadmap

1. Introduction to Communication Protocols

• Why communication protocols are needed
• What CAN is
• CAN arbitration
• Applications and properties of CAN
• Disadvantages of CAN

2. Frames in CAN

• Data, remote, overload, and error frames
• Differences between standard and extended frames
• “Superposition bits” (as heard in the subtitles) and their appearance in active and passive error frames
• CAN protocol versions

3. Errors in CAN

• The five types of CAN errors
• Stuffing and de-stuffing
• Error detection, signaling, and handling
• Error counters, including how they increase or decrease
• Node states based on error counters, including error-active and error-passive states
• Recovery after a node enters the bus-off state

4. CAN Structure and Bus States

• CAN bus structure and differential signaling over twisted-pair wires
• CAN bus levels and nodes
• The purpose of the bus termination component, called a “terminal register” in the subtitles
• CAN transceivers, signal reflection, and CAN bus speed

5. Bit Construction and Synchronization

• How a bit is constructed from segments
• Sampling points and the use of NRZ coding
• The need for bit stuffing
• Bit synchronization, including lengthening and shortening timing segments

6. Miscellaneous Topics

• CAN bus connectors and pinouts
• Where CAN transceivers are used
• Bitrate and baud rate
• Additional topics rendered in the subtitles as “stress hardware” and “energy coding”; these terms may be transcription errors
