一种灵活可配置的嵌入式液晶显示设计方案

介绍了继电保护嵌入式装置中的液晶菜单和图形主界面的配置和显示方法,以层次化的树形数据结构组织菜单,基于分层可复用的组合图元展示主画面,采用灵活可配置的文本描述液晶显示内容。通过液晶配置工具形成配置文本,将产品研发和工程应用解耦,该方案具有很好的推广价值。

This paper introduces the configuration and display method of LCD menu and graph interface of relay protec-tion in embedded devices,with hierarchical tree data structures organize menu,combination primitive layered reusable display based on the main screen,using a text description of the flexible configuration of LCD display content.The formation configu-ration text through LCD configuration tool,the product development and engineering application of decoupling.
