摘　　要：基于STM32F103的电子相框系统读取SD卡中的图像文件通过LCD屏幕将其显示。系统主要由SD驱动、LCD驱动和功能控制模块组成。SD驱动主要由SD接口驱动程序、FAT文件操作程序组成;LCD驱动主要由LCD屏驱动芯片的驱动程序和图片显示程序组成;功能控制模块包括了系统初始化,显示的时间、显示方式的设置,驱动程序调用等功能,功能控制模块是系统的主模块。在介绍了文件系统与图像操作的基础上逐步说明了整个系统的实现。文件系统支持FAT16/32,图像系统支持BMP等多种文件格式。整个系统的设计以模块化为基础,易于升级。Digital Photo Frame based on STM32F103 reads the digital image files from SD card and displays on LCD screen. The digital photo frame includes SD driver, LCD driver and function control module. SD driver consists of SD interface driver and FAT file operation program. LCD driver consists of LCD screen driver and digital image displays program. Function control ;nodule includes system initialize, time and mode set, call drive program and so on. The system realization is introduced after file system and image system analysis. File system is based on FAT16 or FAT32, image system based on BMP file and so on. The design of digital photo frame is modularized and easy to upgrade.
