兩片138級聯實現的功能和154是一樣的，都是4-16譯碼，4線輸入16線輸出控制LED的16列，想一想很好改的

作者: weidoit 時間: 2018-5-18 10:26
軟件不需要改，注意硬件連接的改變，片選使能信號電平等。

修改了用proteus仿真然后就能看見數據傳不過去不知道是哪里錯了

實例66 LED 16×16點陣掃描顯示漢字

⒈ 電路設計…

說明：用一片154（4-16譯碼器）代替2片138（3-8譯碼器），性價比更高。對LED顯示來說，164比595性價比更高（都是串入并出移位寄存器，164控制更簡單）

⒉ 漢字編碼…

⑴ 漢字編碼概述…

⑵ 漢字點陣顯示代碼…

⑶ 漢字點陣取模軟件…

⒊ 程序設計…

⒋ Keil調試…

⒌ Proteus仿真…

154的A,B,C,D四個引腳那個是串行輸入哪個是時鐘呢

你好，請問你的138調試合適了沒，我的正好和你的相反154程序要變為138程序
