求高手指點(單片機怎樣在LCD12864上面顯示變量)

ID:61140 · 發(fā)表于 2022-3-25 08:56

以上是我的程序,我要實現的功能是上電顯示一屏圖片(128*64)三秒,然后跳到文字界面,在文字界面顯示一個0-100的數字變量怎么搞,誠心請教各位大神.要求用匯編語言

單片機源程序如下:

1、LCD屏是一個點陣屏。所以，先要解決點的顯示問題。
2、漢字用的是16*16的點陣，它可以用32個字節(jié)來存儲，所以設立一個32個字節(jié)緩沖區(qū)，起點就設為：BUF_HZ。
3、將屏分成X行Y列，為了簡單化，就分為4行8列吧（應當是64行128列）。
4、寫一個程序起名叫SEND_HZ吧：輸入參數是(X,Y)，輸入則是將:BUF_HZ中的漢字顯示在（X，Y）處。
提示：從BUF_HZ起，將32個字節(jié)送入顯示屏中，每個字節(jié)送入的地址，要求你根據XY計算得出。
5、再寫一個程序起名叫A_HZ吧：程序是將A中的數字，轉換成16*16的點陣，放入BUF_HZ中。
6、現在說你的變量，將0-100的一個變量（三位數），先取一位放入A中，調用A_HZ，現指定顯示的位置（X,Y），調用SEND_HZ。再選擇（X,Y）如法炮制顯示另外二位吧。
7、同理再做一個8*8的顯示程序，相信你也會了。緩沖區(qū)用BUF_ASC，8個字節(jié)就夠了。X取0-7八行，Y取0-15十六列。
如果有興趣，寫一個在屏上任意一處顯示一個點的程序，就更牛了。

1、LCD屏是一個點陣屏。所以，先要解決點的顯示問題。
2、漢字用的是16*16的點陣，它可以用32個字節(jié)來存儲 ...

關鍵我還是不會,單片機新手,這程序還是改的別人的

這就有點難了。懂匯編的都是大佬，你想讓大佬免費給你講？

匯編有點強啊

新手想搞定這個，極難極難。樓主當循序漸進，踏實步進。
我花了許多時間，寫了關于12864LCD點陣屏的顯示子程序。（打點，畫線、定位打點、選位ASC顯示、選位漢字顯示、選位光標閃爍、光標移動操作、屏上數字漢字識別、屏上數字+-操作……）
還用高級語言對它進行了輔助設計（字庫自動生成、自動編碼、任意造字……）。
如此才能做到，分分鐘搞定漢字或點圖顯示、屏幕人機對話。
