1、-. z1632點陣數(shù)字鐘及漢字顯示 作者: HEY | 瀏覽數(shù)(6070) | 評論數(shù)(0) | 2007-08-09一電路原理框架設計制作作品：1632點陣顯示數(shù)字鐘及漢字顯示實現(xiàn)功能：點陣顯示的實時時鐘以及漢字等字符的左移顯示實用特征：采用雙電源供電，斷電后時鐘由電池供電還能繼續(xù)運行，而且準確性較高實現(xiàn)原理：1時鐘顯示是由DS1302準確的時鐘芯片產(chǎn)生時鐘信號并將其送至單片機，經(jīng)過單片機處理后再輸送到點陣顯示模塊。2漢字顯示并左移原理是先寫入與本點陣驅(qū)動相應的代碼進單片機，通過單片機控制程序取表進展處理后送點陣模塊顯示電路主要模塊及原理圖：1單片機最小系統(tǒng)及控制按鍵電路2 DS1302與

2、單片機接口電路DS1302除了系統(tǒng)上電時由系統(tǒng)供電外，如果主電源斷電還有一電池給DS1302供電，防止斷電后DS1302數(shù)據(jù)消失。4點陣行驅(qū)動模塊電路行驅(qū)動采用74LS154416線譯碼器及PNP三極管，由于是1632點陣顯示功率較大故采用8550NP三極管。5點陣列驅(qū)動電路列驅(qū)動采用74HC595移位存放器將控制位級連接入單片機，每個74HC595數(shù)據(jù)輸入端單獨接單片機。1632點陣模塊由8塊小的88點陣模塊通過級連而拼成，共16行，32列。二：主要元器件選擇：單片機：AT89S51采用市場上比擬常用的AT89S51三極管：點陣的行驅(qū)動電路用，這里采用PNP管，具體型號用8550點陣塊：為了
