Design of User Interface Framework for Agricultural Vehicle Electronic Device

介绍了一种农机车载电子设备显示界面框架的设计与实现。基于C语言分析设计了界面框架的数据结构,使用分层的数据结构设计方法实现了多类型数据的显示需要和灵活的界面类型组合方式,以极少的开销实现了多级菜单。将内容数据与操作函数分离,解决了操作函数复用的问题,同时提高了程序的可维护性。提出的新型的界面显示框架实现了多种农业装备常见的界面应用类型,解决了小屏幕嵌入式系统显示界面移植性差问题。

The design and implementation of display interface framework on the agricultural vehicle electronic device was described. Based on the C language,the data structures were analyzed and designed, and the hierarchical data structure was designed to achieve the multiple type needs of data display and flexible interface type combinations,and a multilevel menu was achieved with the very low memory overhead. The datum and functions were separated to solve the problem of manipulation functions and increase the maintainability of the program. The new interface framework was proposed to improve the portability of the embedded system＇s small displays for various types of the agrieultural equipment application.
