點(diǎn)陣顯示屏成功點(diǎn)亮原理圖程序

1、16×16點(diǎn)陣顯示屏成功點(diǎn)亮！ 看到江同學(xué)的3216屏（），對于我來說，稍顯復(fù)雜，所以決定做個(gè)1616的屏看看效果，原理圖就是以下了，注意做1616時(shí)，要去掉一個(gè)74ls154(當(dāng)然這里也能換用74hc154，雖然功耗大，但價(jià)格較低)，經(jīng)過兩天的奮斗，終于完工了。簡單的調(diào)試后，點(diǎn)亮了！編個(gè)流動(dòng)顯示的程序，哈哈，很炫啊。心動(dòng)不如趕快行動(dòng)??！ 我是把點(diǎn)陣塊焊到一塊板子上，可方便檢查有無虛焊，控制部分放到了另一張板上，做成的實(shí)物圖就是下面的了，視頻在這里： （注：以下原理圖均來自）/*程序名稱：led1616點(diǎn)陣流動(dòng)顯示漢字簡要說明：最大可顯示16*16漢字 p0口接上行線，p2口接下行線
