摘要
随着嵌入式的发展,触摸屏以友善的人机交互性、操作简单灵活、输入速度快,已逐渐取代键盘,成为嵌入式系统的主流输入设备;而Qt作为跨平台的图形用户界面工具包诞生以后,已经扩展到了包括便携式设备在内的几乎当今程序设计的所有领域。以S3C2416为例,介绍了在Linux平台下支持触摸屏的Qt/Embedded移植的详细过程,包括系统环境介绍、带触摸屏库的Qt/Embedded的编译、Linux文件系统设置等,并挑选了一个demo程序对移植情况进行了检验。最后对支持触摸屏的嵌入式系统作了初步展望。
Along with the fast development of embedded system, touch screen has gradually replaced the keyboard and becomes the main input device in embedded systems. QT invented as a cross-platform GUI （ graphical user interface） toolkit has extended to many fields of program design including portable devices. In this paper S3C2416 is exemplified to introduce the process of Qt/Embedded transplant supporting touch screen, which includes the system environment introduction, Qt / Embedded compiler with touch screen library, file system settings and so on. Then a demo program is selected to test the transplant. At last an outlook is made for the embedded system suooorting touch screen.
