基于NiosⅡ的LCD触摸屏应用设计

Design of LCD Tuch Screen Application Based on NiosⅡ

为了实现触摸屏作为设备的人机接口界面,使用FPGA的SOPC技术,在FGPA中构建了NiosⅡ处理器系统作为触摸屏的控制器,编写NiosⅡ控制程序实现了触摸屏信息显示和触控功能。程序中设计了显示区域规划结构,为系统的信息显示和触控功能的实现提供了一种相对通用的方法,能够增加代码的重用性和通用性,简化了显示界面的程序设计过程,提高了系统性能和开发效率。

In order to achieve the touch screen as the man-machine interface equipment,using SOPC technology,NiosⅡ processor system in FGPA was builted as a touch screen controller.Screen display and touch screen capabilities have been realized by writing NiosⅡ control procedures.The designed planning structure of Display Area has became a relatively common method to the information display and touch functions of the system.It can increase code reusability and versatility,simplify the program design process of display interface,and the system performance and development efficiency was improved.
