16*16滾動點陣屏+音樂盒C語言源程序

 快樂讀書法 2015-12-06
    這個東西是09年剛學(xué)單片機時做的,，基于51單片機,。點陣屏用的是一個集成好的模塊，就是四個595兩兩級聯(lián)分別控制行和列,，屏可能有點老，所以不是很亮,。字摸直接用網(wǎng)上的字摸提取軟件就能提取,。另外用定時計數(shù)器產(chǎn)生方波做了一個音樂播放器（用了一個運放），放的是天空之城的音樂,，同時用一個兩位數(shù)碼管顯示當(dāng)前的音樂音階（第一位數(shù)碼管表示高中低音）,。感覺里面用了不少51的資源，挺好的程序,，現(xiàn)在完全開源的給大家分享出來
