摘要
嵌入式技术在工业和日常生活中变得越来越普及,触摸屏作为交互终端已经逐渐取代键盘成为嵌入式系统的输入设备。使用TQ2440开发板,通过对嵌入式Linux内核中触摸屏驱动的研究,编写和移植了触摸屏的驱动程序,校准之后触摸屏可以正常使用。
With the development of information,intelligence and network,embedded technology is becoming increasingly popular in the field of electronic industry as well as daily life. As the medium for the terminal-user interaction,the touch screen has gradually replaced keyboard to be the inputting equipment in the embedded system. In this experiment,using the TQ2440 board,driver of touch screen in Linux kernel is introduced briefly,write and transplant the touch screen driver,touch screen can be used after calibrating.
