結(jié)論 本文設(shè)計(jì)的是 16ｘ 64 的點(diǎn)陣 LED圖文顯示屏，通過(guò) LED 顯示屏穩(wěn)定顯示清晰的圖形和中英文字符，圖形或文字顯示有向上移入、靜止、向上移出等顯示方式。 在此過(guò)程中，我還 了解到實(shí)踐必須要有相關(guān)的理論知識(shí)作為支撐，做設(shè)計(jì)之前必須要把相關(guān)的理論搞清楚，要有總體的設(shè)計(jì)思想。我還想感謝我們的大學(xué)，是它給我提供了良好的學(xué)習(xí)設(shè)施，例如圖書(shū)館，那是知識(shí)的海洋，在那里汲取知識(shí)，永不知倦。 //行掃描數(shù)組 uchar code
