基于单片机的电子相册设计.doc

摘 要 随着科技的不断发展，人民对物质生活、精神生活要求的不断提高，很多最新的服务于人民大众生活的种种科技产品都随之出现，电子相册也随之诞生。电子相册是用相关硬件经过加工、焊接而成的区别于软件类型的电子相册，它一般由三部分组成：TFT液晶面板，主控芯片，外部相框按钮。硬件电子相册有着很多传统纸质相册无法比拟的优点：高分辨率，易保存、色彩鲜艳。它摆脱了传统电子随着时间流逝，照片色彩褪色、无法辨认的缺点。生动、形象、保存时间长，电子相册可以设置各种切换模式，从而使照片看起来更具有动感，更能给人美的享受。高级电子相册还可以单独为每张照片配置独立的背景音乐，独立的现实各种特效，同时电子相册的保存时间也远远大于纸质的相册便于再生，不用担心丢失。由于电子相册是通过读取相应格式的图片显示在液晶面板上来实现的，从而图片源可以很方便的在电脑上复制备份，克服了传统纸质照片的不可再生性。本次毕业设计电子相册。本文将从电子相册概述，功能简介，硬件电路实现，软件程序实现等方面来综合论述。本次设计存储器采用通用的SD卡存储设备来存储相应图片。为了适应SD存储设备的FAT存储扇区特点，此次设计采用的SST89E516RD芯片，该芯片有1K的RAM符合SD每个扇区的需要。 关键词： 单片机 SST89E516RD 电子相册 SD卡 With the continuous development of science and technology, the people’s life and the spirit of material life requires unceasing enhancement. A lot of the latest products that serve the people of the public life of all technology products appear and the electronic albums also comes. Electronic album is processed with related hardware and it is different with the software type of electronic albums. It generally consists of three parts: TFT LCD panel ,control chip and external frame button. Hardware electronic albums have many advantages that the traditional paper albums don’t have: high resolution, easy to save, bright colors. It breaks away from the shortcomings of the traditional electronic albums for example color fading as the time goes by ,hard to identify. It also can set up various switching mode to make the photographs more dynamic and to give us more beauty. Without that , the electronic albums can preserve for a longer time than the paper albums . Aavanced electronic albums can set the different background music for each photo. Because electionic albums show the photos in the LCD panel by reading the format images ,thus saving the photo is easy and overcome the shortcomings of the traditional albums. The graduation design I will realize is the hardware electronic albums. With the so many advantages that the traditional don’t have, the electronic albums are instead of the traditional ones step by step. Thi
