pov單片機

⑴ 跪求直流電機恆速控制電路圖和程序，我做的POV LED恆速屏畢業設計，就差直流電機恆速了

你媽 的 這都 不懂 還上學干什麼呀 父母花錢就是讓你干這個的

⑵ 單片機做pov顯示時鍾，轉速過快會有問題嗎

ds1302時鍾晶元是不斷地讀取內部數據送到外部顯示的，
模擬的時候用的是系統時間，
如果出現時快時慢，要麼是CPU負載100％卡了，要麼就是你的顯示程序不合理，顯示程序沒有實時地反應秒的狀態。我以前做的都沒這情況。顯示刷新專門放在一個定時器里定時刷新

⑶ 拿51單片機可以做什麼簡單逼格高的小東西.不想

用一個16*16點陣模塊做個俄羅斯方塊游戲機，或者用兩個點陣，搞一表白牆。

⑷ POV啥意思

好像是視覺暫留的意思，有好多關於POV的單片機趣味實驗，不知道是不是你想要的答案！！

⑸ 《51單片機POV趣味製作詳解》哪有賣的

在卓越亞馬遜上面好像有，這本書真的很不錯哦，我從學校的圖書館借了一個多月，都捨不得還，貌似我還有這本書的源程序，電子檔的

⑹ 請單片機編程高手幫幫忙！！！ （1） 製作一個由16隻 LED構成的線狀點陣及其控制電路，安裝於可旋轉的平台

在網上搜POV LED ，很多人在做，淘寶也有賣

⑺ pic 16f877a 頭文件

也就匯編的頭文件PIC16F877A.inc和C語言的pic1687x.h這兩種文件。
想要找匯編的頭文件，只要你的電腦裝了MPLAB就行，直接在MPLAB的安裝目錄下找即可，比如我的MPLAB7.50是裝在D盤的，我要找這個匯編的頭文件就是在D:\Program Files\Microchip\MPASM Suite這個目錄里。 而PIC單片機官方沒有出針對PIC16F877A的C語言編譯器，一般很多人都用PICC編譯器，我電腦上的PICC8.50也裝在D盤，D:\HT-PIC\include下找就行pic1687x.h
