Ⅱ 如何用c51單片機和8255擴展晶元設計16*16LED點陣顯示屏設計

一般建議用2片3-8解碼器做片選信號（控制16個口），然後再用兩個P口（也是16腳）進行數據傳輸，這樣就能實現16*16的數據顯示了，建議PROTUES模擬，網上這樣的例子很多，但模擬時可能效果不如實際開發板上效果好。

這里有個視頻教材，protues 模擬實現，很好很強大，希望對你有用。

另外 如果有試驗箱，就會有指導手冊和常式，多問問老師。

Ⅲ 基於51單片機的旋轉led屏中，紅外接收管還有紅外發射管的作用是什麼

做為刷新的零點。轉速不是絕對穩定的，延時不是絕對准確的。無論程序執行到哪裡，只要收到信號就會以此為零點開始刷屏，物理位置不會變。

旋轉led是由直流電機的高速旋轉，帶動了若干個LED，由單片機晶元控制LED的亮滅，利用人眼的視覺暫留原理，從此就可以在空中形成各種圖案。
51單片機是對所有兼容Intel 8031指令系統的單片機的統稱。該系列單片機的始祖是Intel的8031單片機，後來隨著Flash rom技術的發展，8031單片機取得了長足的進展，成為應用最廣泛的8位單片機之一，其代表型號是ATMEL公司的AT89系列，它廣泛應用於工業測控系統之中。很多公司都有51系列的兼容機型推出，今後很長的一段時間內將佔有大量市場。51單片機是基礎入門的一個單片機，還是應用最廣泛的一種。需要注意的是52系列的單片機一般不具備自編程能力。

Ⅳ 基於51系列單片機的LED顯示屏開發技術 這本書怎麼樣

是國內第一本針對鐵電單片機的書籍，為初學鐵電單片機或是希望了解該單片機的讀者提供了較為全面的資料和開發常式。此外還對通用LED顯示屏上位機控制軟體設計、LED顯示屏控制系統常用時鍾晶元DS1302、溫度感測器DS18B20等模塊控製程序和硬體電路進行分析和講解。這些內容是作者近幾年來部分開發工作的實踐總結，有些是根據實際生產產品的提煉和推廣。

Ⅳ 求基於51單片機的LED點陣顯示屏系統的設計與實現的論文

給你一個源代碼吧，自己分析，用匯編寫的。本人編寫後親試過，只要一片C8052S的最少系統就能工作 驅動市售＄5.0單元板（32*64）。

Ⅶ 基於51單片機的led點陣顯示屏設計原理與電路圖

51和led點陣一般要用到動態掃描的方式，也就是顯示的畫面不是一下子就把整個畫面的內容全部顯示出來，而是逐行顯示的，只不過顯示的頻率超過了50HZ
甚至更高，所以我們看起來是「不晃眼」的。也就是說，屏幕顯示是由行顯示組成的（即子程序）。行顯示再細分就是有位顯示組成，不過行顯示就不用逐位顯示了。其實行顯示就是串入並出，即行顯示是一下子就顯示出來的。
我給你傳一份資料你參考一下。。。。。。
