This paper presents an implementation of the Qt4 test bench based on ARM9. With Linux as the operating system, based on ARM9 system board, Qt4 test bench is implemented and completes the corresponding tests. The process of the implementation combining the build of compiler environments, the kernel transplant, the production of the root filesystem, drivers installation, and the process of Qt/Embedded transplant supporting touch screen, is detailed explained. At last, the console, based on Qt/Embedded for GUI support system, is presented to control four applications, each of which has tested individual objective functions related to USB camera and LCD display.本文提出了基于ARM9的Qt4测试工作台的一个应用。以LINUX作为操作系统,基于ARM9系统平台,Qt4测试工作台得以运用并完成了相关各项测试。应用的过程在文章有详细的解释,这一过程综合了各种编译器环境的建造,内核移植,根文件系统的产生,各种驱动器的安装,以及Qt/嵌入式移植为触摸屏提供支持的过程。最后,提出基于Qt/嵌入式 GUI图形用户界面支持系统的控制台来控制四种应用程序。其中每一种应用程序都已经完成了对于与USB通用串行总线接口摄像头和LCD液晶显示器显示相关的每一个客观功能的检测。外行翻译,仅供参考,欢迎指正
