接线图在嵌入式GUI中的综合运用

Comprehensive Use of Wiring Diagram on Embedded GUI System

主要讨论了在嵌入式Linux装置中,如何利用后台计算机上的工具软件定制接线图,来满足复杂情况下嵌入式图形用户接口的需要。通过对嵌入式Linux装置功能的需求分析,在嵌入式Linux装置中采用了移植Microwindows作为其图形用户接口的解决方案。而后台计算机工具软件负责生成图形、图元文件并存入数据库中。装置与工具软件之间的数据交换采用SQLite数据库。经过对Microwindows系统体系结构的分析,SQLite数据库数据结构的设计,以及后台配置工具的设计分析,代码的移植和最终程序的编写,成功的实现了利用工具软件定制接线图以满足嵌入式GUI的具体应用。

This paper discusses how to use computer software tool to custom wiring diagram in the embedded Linux device,which can meet the needs of the embedded GUI system in complex circumstances.Through the requirement analysis of the embedded Linux device＇s function,utilize transplanting Micro-windows in embedded Linux devices as the GUI system solutions. The background software tool is responsible for generating graphics and metafile into SQLite database,so the SQLite database is used for the data exchange between devices and software tools.After the analysis of Micro-windows system architecture,the design of SQLite database structure,the design and analysis of background configuration tools and code transplant and final code programming.
