基于嵌入式Linux系统数码相框的设计与实现

摘要

数码相框作为嵌入式的典型应用，比普通的相框更灵活多变。根据数码相框的需求分析开始，采用了嵌入式Linux的Libmad音频编解码技术和FrameBuffer视频编解码技术，完成了数码相框软件的设计与开发工作。最后采用C语言编写后交叉编译、移植开发、实现了数码相框。%Digital photo album as the typical application of embedded, it more than the ordinary flexible frame because now ordinary paper photos easy yellowing, aging, and high cost shortcomings. In this paper, according to the requirement analysis of digital photo album, adopting to the embedded Linux Libmad audio codec technology and FrameBuffer video codec technology, completed the design and development of digital photo frame and software work. Finally, the use of C language cross compiler, after transplantation, the implementation of digital photo album.
