摘要
以STM32F407微型控制器和控制器局域网络(CAN)总线通信技术为基础,致力于设计一款全液晶汽车仪表,以实现仪表与整车系统通过CAN总线网络节点的高效通信。采用CAN总线通信方式,元器件与控制元件(ECU)之间的信息传递更加可靠。根据新能源汽车仪表的功能需求,对整车系统应用层进行明确定义,进行了总体结构的硬件与软件设计。对该系统进行测试和分析,结果表明该设计不仅提供了更简单的接线方式,还实现了模块间的快速通信,同时具备全液晶显示的优势。
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.
