標題: 關于51單片機液晶顯示程序,不能同時顯示字母和漢字?
請問為什么液晶顯示不能同時顯示字母和漢字啊！是代碼的問題嗎？請問怎么改啊？這是我的仿真結果，亂碼！

你的答案很正確，是代碼問題，所以不用貼亂碼了。
點陣顯示器，它并不知道顯示的是啥，只是按既定的規則顯示點。
既然顯示的點可以成英文，就可以成漢字，也可以是圖形，硬件正確就是軟件問題。

顯示的方法，要修改，英文一般是顯示5X8點陣，而中文一般是16x16點陣（還有上下半截之分，取模時還分從左往右、還是從右往左），也有24點的、或更多點的，看顯示的需要。

下一樓回答正確，確實字母和漢字的點陣出現問題，我全部考慮8X8點陣了！
還是謝謝你！
