摘　　要：基于嵌入式uCLinux内核和MiniGUI软件平台,设计并实现了公交车站广告机的用户界面。对相应的开发环境进行了搭建,并给出了运行环境的执行步骤。在用户界面设计中,我们采用了双缓冲技术,对动画和滚动字幕的速率进行了精确控制并提出了相应算法,最后实现了画面的剪裁。该文提出的解决方案已在上海市部分公交车站成功运行。This paper introduces design and implementation of user interface(UI) of ad-displayer at bus station based on embedded uCLinux kernel and MiniGUI.It puts up the related develop environment and gives the executive process of run environment.During the design of UI,we adopt double buffers,control animation and scrolling subtitle velocity accurately and propose relevant algorithm,and implement image clipping in the end.The solution proposed here has already been successfully carried out at some bus stations in Shanghai.
