基于vs1003的mp3音樂播放器設(shè)計(jì)

1、畢業(yè)設(shè)計(jì)說明書（論文）I基于VS1003的MP3音樂播放器設(shè)計(jì)摘要：本文在具體分析了STC12C5A60S2單片機(jī)的技術(shù)特點(diǎn)與MP3音樂播放系統(tǒng)功能需求的基礎(chǔ)上，提出了一種利用單片機(jī)實(shí)現(xiàn)簡易MP3播放器的方法，同時(shí)給出了具體軟硬件設(shè)計(jì)的方法。本系統(tǒng)利用STC12C5A60S2單片機(jī)作為CPU進(jìn)行總體控制，單片機(jī)通過FAT32文件系統(tǒng)讀取SD卡的數(shù)據(jù)，并傳輸給MP3音頻解碼芯片VS1003進(jìn)行音頻數(shù)據(jù)解碼，實(shí)現(xiàn)歌曲播放功能。通過控制按鍵，

2、實(shí)現(xiàn)對(duì)歌曲的選擇及音量調(diào)節(jié)。播放的同時(shí)，液晶屏上顯示歌曲相關(guān)信息。相關(guān)的硬件脫機(jī)實(shí)驗(yàn)結(jié)果表明，本系統(tǒng)達(dá)到了既定的設(shè)計(jì)目標(biāo)。關(guān)鍵詞：單片機(jī)；音頻解碼；FAT32DesignofMP3MusicPlayerBasedonVS1003Abstract：BasedonthedetailedanalysisofthetechnicalacteristicsofSTC12C5A60S2theneedsofMP3musicplayersystemfu
