【正文】 重慶郵電大學(xué)移通學(xué)院畢業(yè)設(shè)計（論 文） I 摘 要 隨著科技的不斷發(fā)展，人民對物質(zhì)生活、精神生活要求的不斷提高，很多最新的服務(wù)于人民大眾生活的種種科技產(chǎn)品都隨之出現(xiàn)，電子相冊也隨之誕生。電子相冊是用相關(guān)硬件經(jīng)過加工、焊接而成的區(qū)別于軟件類型的電子相冊，它一般由三部分組成： TFT 液晶面板，主控芯片，外部相框按鈕。硬件電子相冊有著很多傳統(tǒng)紙質(zhì)相冊無法比擬的優(yōu)點：高分辨率，易保存、色彩鮮艷。它擺脫了傳統(tǒng)電子隨著時間流逝，照片色彩褪色、無法辨認的缺點。生動、形象、保存時間長，電子相冊可以設(shè)置各種切換模式，從而使照片看起來更具有動感，更能給人美的享受。高級電 子相冊還可以單獨為每張照片配置獨立的背景音樂，獨立的現(xiàn)實各種特效，同時電子相冊的保存時間也遠遠大于紙質(zhì)的相冊 ， 便于再生，不用擔(dān)心丟失。由于電子相冊是通過讀取相應(yīng)格式的圖片顯示在液晶面板上來實現(xiàn)的，從而圖片源可以很方便的在電腦上復(fù)制備份，克服了傳統(tǒng)紙質(zhì)照片的不可再生性。 本次畢業(yè)設(shè)計 是基于的單片機 電子相冊。本文將從電子相冊概述，功能簡介，硬件電路實現(xiàn)，軟件程序?qū)崿F(xiàn)等方面來綜合論述 電子相冊 。本次設(shè)計存儲器采用通用的 SD 卡存儲設(shè)備來存儲相應(yīng)圖片。為了適應(yīng) SD 存儲設(shè)備的 FAT 存儲扇區(qū)特點，此次設(shè)計采用的SST89E516RD 芯片，該芯片有 1K 的 RAM， 符合 SD 每個扇區(qū)的需要。 關(guān)鍵詞 ： 單片機 SST89E516RD 電子相冊 SD 卡 重慶郵電大學(xué)移通學(xué)院畢業(yè)設(shè)計（論 文） II Abstract 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 es. 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 shortings 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 overe the shortings 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. This paper will synthesis elaborates the graduate design in five aspects: the overview of electronic albums ,functions, hardware circuit implementation introduction,software program realization, finished thing debugging. This graduation design use the general storage devicesSD card to store the corresponding picture. In order to adapt to the SD storage devices, I choice the SST89E516RD chip because it has 1K RAM to meet the needs of the SD card. Keywords： SST89E516RD 。MCU 。 Electronic Album。SD Card 1 目 錄 摘 要 ....................................................................................................................
