【摘要】 在嵌入式系统中,矩阵键盘越来越成为一个重要的人机交互设备。本文就将介绍在嵌入式Linux系统下,Qt/Embedded图像用户程序和矩阵键盘设备之间是如何进行通信的。首先,我们给出了在S3C2410开发板上矩阵键盘的电路设计,然后介绍了Qt/Embedded应用程序响应矩阵键盘设备的工作机制和需要完成的工作,即需要完成Linux设备驱动和Qt/Embedded设备驱动的编写,最后结合大量源代码进行分析和实现,给出了基于Qt/Embeded的矩阵键盘驱动的开发方案,并成功的在S3C2410开发板上实现了矩阵键盘与QT/Embedded应用程序的通信。更多还原

【Abstract】 In imbedded system, the matrix keyboard becomes an important man-machine interactive equipment. This article introduces how Qt/Embedded picture user program carries on the correspondence with the matrix keyboard equipment in imbedded Linux system. First, we give the matrix keyboard circuit design on the S3C2410,then introduced the work mechanism of Qt/Embedded application responding matrix keyboard equipment, namely needs to complete the compilation which the Linux equipment driver and the Qt/Embedded equipment driver, in the end,introduces the realization by analyzing massive sources code.更多还原
