標(biāo)題: 求大神看一下單片機(jī)+LCD12232顯示的字體為什么是鏡像的

根據(jù)lab8000用proteus仿真的 剛剛接觸這個(gè)LCD，可能連線不對(duì)，單片機(jī)代碼如下
  1. #include<reg51.h>
  2. #define PD1 61

  4. unsigned char Column;

那就取模的時(shí)候先鏡像一下，顯示就是正的了

程序沒錯(cuò)。很久以前做過，仿真就這樣是鏡像 的，同樣程序放實(shí)物就正確的。

大佬，那您能幫我看下我定義的應(yīng)該是在第二行第一位的位置，為什么在中間呢

小哥，你是在做漢字滾動(dòng)的設(shè)計(jì)嗎
作者: tangzhan    時(shí)間: 2021-12-24 08:25
不同廠家生產(chǎn)的屏方向不同
