摘　　要：目前,uc/os-ii在嵌入式系统中得到了广泛的应用,但适用于μc/os-ii的图形界面却很少。本文介绍了一种适用于μc/os-ii的图形界面μC/GUI的体系结构和特点,给出uC/GUI驱动程序和应用程序的编写实例。同时对操作系统接口文件的编写及自定义中文小字库的实现进行了详细介绍,尤其是自定义中文小字库的提出,使得汉字库仅仅占用几千个字节。不但实现了汉字显示,还节约了宝贵的存储空间。Nowadays, uc/os-ii is applied widely in embedded system. However, there is few GUI for uc/os-ii up to date. This article describes the structure and feature of uC/GUI, and also illustrates the process of programming uC/GUI driver and application. The interface file of operating system and the mini Chinese characters＇ storeroom are described detailedly in this article. Especially, because of being brought forward the mini characters＇ storeroom, thousands of bytes of memory are used merely. Not only displaying Chinese characters, but also saving memory.
