Research on Automotive Instrument Display System Based on STM32 Microcontroller
Based on the STM32F407 microcontroller and Controller Area Network(CAN)bus communication tech-nology,we are committed to designing a full LCD automotive instrument panel to achieve efficient communication between the instrument panel and the entire vehicle system through CAN bus network nodes.By using CAN bus commu-nication,the information transmission between components and control components(ECU)is more reliable.According to the functional requirements of new energy vehicle instruments,the application layer of the entire vehicle system is clearly defined,and the overall hardware and software design are carried out.The system was tested and analyzed,and the results showed that the design not only provides a simpler wiring method,but also achieves fast communication between modules,and has the advantage of full LCD display.
