Introduction to CAN & CANopen

This lecture covers the introduction to Controller Area Network (CAN) and CANopen protocols used in spacecraft avionics systems. It explains the structure of avionics systems, different levels of complexity, network standards, future trends, onboard bus requirements, and the overview of buses and networks. The lecture delves into the details of CAN and CANopen protocols, including their layers, standards, physical characteristics, and communication services. It also discusses the ESA standards related to CAN in space and the communication objects used in CANopen. The lecture concludes with topics like error control services, process data objects, time objects, redundancy management, and the communication model in CAN systems.
