摘要
基于ARM+Linux的架构,通过CAN总线获得数据,再利用嵌入式系统平台的构建思想,实现了在嵌入式Linux操作系统下,基于ARM和MiniGUI环境的车载信息的图形化显示。介绍了虚拟仪表系统的体系结构、数据采集节点的构成及Linux环境下CAN总线驱动程序的实现。
In order to design an all-digital instrumentation systems for car, ARM and Linux-based structure is adopted, the method of the embedded systems platform is taken and data is accessed from the CAN bus, automotive information with a liquid crystal display in the environment of the MiniGUI and ARM microprocessor which embedded Linux operating system is realized. And then the structure of virtual dashboard and the node of data acquisition are introduced, and eventually CAN bus driver is realized.
