摘要
阐述了一种基于ARM的全数字彩色液晶仪表的设计思想、工作原理及实现方法.该系统利用高性能微控制器AT91SAM9263结合嵌入式操作系统μC/OS-II及嵌入式图形用户接口μC/GUI构建了具有CAN通信、显示汽车所有运行参数并具有故障报警功能的汽车车况综合信息平台,具有较好的扩展性,是汽车仪表数字化智能化的必然发展趋势.
This paper introduces the design thoughts, the working principle and the realization of a kind of digital colorized LCD automotive instrument based on ARM. By using high-performance microcontroller AT91SAM9263, combined with embedded operating system μC/OS-Ⅱ and graphical user interface μC/GUI, the system constructs the unified information platform of the automotive working conditions, provided such functions as the real-time data communication with CAN bus and could display all vehicle operating parameters with alarm function. This expansible system will be a direction in the digitized and intelligentized progress of the automotive instrument.
