12864程序中上半屏下半屏的問題

ID:138194 · 發(fā)表于 2016-12-3 20:56

  for(j=0;j<16;j++)
      {
      write_dat(table[ i][j]);
      }
16在這指16列，可是上半屏才8列。如果這樣寫就一起把下半屏一起寫了。為什么還寫
for(i=0;i<32;i++)
      {
      write_cmd(0x80+i);
      write_cmd(0x88);
      for(j=0;j<16;j++)
      {
      write_dat(table[i+32][j]);
      }
      }

常見的12864，一個(gè)漢字，上半部16列8行，下半部16列8行，組合起來就是16*16點(diǎn)陣的漢字。

你說的是半角字符？16*8的？

漢字（全角字符）是16*16的。

比如說是20*20；30*30的。是不是只能通過取模以圖片的形式顯示出來

凡是LCD自帶的漢子庫，基本上都是16*16點(diǎn)陣的漢字。如果用繪圖模式可以改其他的。但是每列8個(gè)點(diǎn)（一個(gè)字節(jié)）是不容易改的。當(dāng)然，多余的閑置是可以的。

我推薦的所有案例都是帶proteus仿真的，而proteus元件庫中沒有帶漢字的12864芯片，沒法提供不帶漢字庫的proteus仿真案例。但電路、程序和編程思路是可參考的。
