摘　　要：随着人们现代生活水平的日益提高,数码相框已经成为人们存放读取照片的首选工具,它不仅综合了多种功能并且方便实用,使其得到了越来越多人的青睐。该设计采用的是基于ARM Cortex-M3内核的STM32F103ZET6微控制器,以GUI为用户控制界面,利用SD卡进行存储,通过FAT文件系统进行SD卡中的文件读取功能,系统移植成功后加入应用程序实现VS1003播放歌曲以及TFT液晶显示图片的功能。由于采用TFT-LCD触控屏设计,使得整个系统实现了良好的人机交换,不仅符合现代的科技发展,并且适应当代人的生活习惯。With improved living standards,digital photo frame has become the tool for the majority of young people to store and read photos. It gets more and more attractions for its integrated functions,convenience and practical usage.This system uses the STM32F103ZET6 based on ARM Cortex-M3 core as a micro-controller and the GUI-based control interface. It adopts the FAT file system to read the files stored in the SD card. After system transplantation,application programs are designed to achieve the audio decoder VS1003 B playing a song and TFT-LCD display. TFT-LCD touch screen design makes the whole system achieve a good human-computer interaction,which not only complies with modern technology development but also adapts to the habits of contemporary people.
