Design of a CANopen Slave Node Based on AT90CAN128


Article Preview

As an application layer protocol of CAN bus, CANopen has wide application in industry. This paper presents a kind of CANopen slave node based on AVR hardware platform of AT90CAN128. Firstly the structure of the slave node hardware platform of the AVR microcontroller AT90CAN128 and CAN bus control based on embedded CAN driver module CTM1050 is proposed. Then the open-source protocol stack CANFestival software design and the specific method are described. CANopen network testing platform is built to test the design of the CANopen slave node. The experimental results illustrate that the proposed solution and implementation method is correct and effective.
