中文摘要: 介绍了基于飞思卡尔芯片i.MX27和嵌入式linux系统下的触摸屏硬件的连接设计和软件的驱动设计，并依照此设计实现了触摸屏的从硬件到软件的驱动系统。该实现主要应用于家庭无线智能控制系统中。文章首先介绍了触摸屏的实现原理，然后介绍了触摸屏芯片AD7873的特性，在此基础上设计了AD7873与i.MX27和触摸屏的连接PCB图，最后依照硬件连接图设计了嵌入式Linux下的驱动，并成功通过了tclib触摸屏专业测试软件的测试，在家庭智能网关系统的测试中也成功运行，实现了从硬件到软件的嵌入式下触摸屏的驱动系统设计
Abstract:This paper gives an introduction about hardware connection designing and software driver designing based on FreeScale’s CPU and embedded Linux system. According to that idea, the paper designs the driver system from hardware to software. The driver system will be applied to the home wireless control system. It first introduces the theory of the touch screen, then introduces the characteristics of the AD7873. Based on the content introduced above, it designs the PCB photo of the system. It designs the soft driver which is successfully tested by the professional soft TCLIB. The results of the home smart control system are promising and convert the driver system from hardware to software under the embedded system.
keywords: ARM embedded system touch screen AD7873 driver
