Abstract
Aiming at the CAN serial communication implemented on Micro-Controller Unit(MCU),this paper proposes a type of multi-point communication network composed of C8051F02X series MCU,CAN port control chip and serial transceivers.The hardware circuit design and software flow chart are introduced at the beginning.Then the data stream pickup and delivery problem and the CAN frame structure are illustrated in detail.At last analysis is presented for synchronization of CAN bus network and CAN port control chip.
A significance statement is not available in the OpenAlex record.
