基于VxWorks的多页面程序框架设计

摘要

In the development of embedded systems, we need some user friendly interfaces to carry out some man machine conversation operations. This paper introduces a design of multipage graphical interfaces frame based on VxWorks. Operating system of VxWorks and its multimedia library (WindML) are introduced briefly, and some key points of the development of graphical interfaces frame are discussed particularly. We also bring forward a way of the design of multipage graphical frame interfaces. Our design takes advantage of multitasking environment of VxWorks and plenty of API functions of WindML. The design is very available and significative in practice.%在嵌入式应用开发过程中,有时需要友好的用户界面来完成一些人机互动操作.本文介绍在VxWorks操作系统下的多页面图形界面程序框架的设计,对VxWorks操作系统和其自带的多媒体库(WindML)做了简要介绍,重点讨论了图形界面开发过程中的关键问题,提出了多页面图形界面程序框架的设计方法.本设计充分利用VxWorks操作系统处理多任务能力强的优势以及WindML提供的丰富API函数,在实际中有一定的应用价值和参考意义.
