Title Software and Hardware Realization of CAN Bus Interface Based on STM32

Abstract The CAN bus has been widely applied in the current technical environment, especially in the automotive electronic field。 Based on CAN two-machine communication, this paper introduced the basic standard of CAN bus, combed the basic principle & development history of CAN bus receiving and sending and clarified the design method relevant to CAN bus。 Further, this paper introduced the used components and designed the circuit of CAN bus nodes。 The system is composed by single chip microcomputers STM32F103ZET6 and its external equipment and chip TJA1050 to complete the receiving and sending process of CAN two-machine communication。 Finally, this paper presented the software design and flow diagram of CAN two-machine communication。

The CAN has been applied in various fields。 This design helps us to understand its basic receiving and sending process as well as hardware application circuit design。 Based on the above mentioned, the multi-function expansion can be further conducted。

Keywords: CAN bus; STM32F103ZET6 single chip; two-machine communication
