摘要:

针对嵌入式应用领域下的实时高质量图形开发困难的问题,引入一种嵌入式下图形开发工具Tilcon,并对Tilcon的程序开发方法和流程进行深入分析和研究。在此结合Vxworks系统,利用Tornado开发环境,WindML图形库组件层次结构的配置,在此基础上设计开发智能水表的图形实例,实现嵌入式系统下图形设计与开发。该设计是基于三方嵌入式软件进行联合开发,解决了嵌入式Vxworks下的图形显示与实时刷新困难的问题,再结合相应的硬件,具有很大工程使用价值。

According to developing difficultly of real - time and superior quality graphics interface in embedding application domain, Tilcon which is an embedded graphics developing tool is introduced, the method and process of the program development about Tilcon are analysed and researched. Combining VxWorks operating system, making use of Tonado environment and configuring WindML, the article designs a graphics example on intelligent water,and achieves development of embedded graphics. The design is developed based on three software'sunion,and solves the problem of real - time graphics display and update based on Tilcon in VxWorks. It has important engineering practical value according to suitable bandware.

According to the implementation of real-time control system Chinese UI based on VxWorks, some concepts of these commonuse UI element and relationships between them are abstracted, then the development platform for this kind system Chinese UI on these concepts is developed. The platform, which used the WindML library of VxWorks at the bottom layer and is organized by the mechanism of UI element manage and event-driving, provided interfaces for upper layer to build certain UI.
