12864程序中上半屏下半屏的问题

ID:138194 · 发表于 2016-12-3 20:56

  for(j=0;j<16;j++)
      {
      write_dat(table[ i][j]);
      }
16在这指16列，可是上半屏才8列。如果这样写就一起把下半屏一起写了。为什么还写
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]);
      }
      }

请教大神指教！！！

常见的12864，一个汉字，上半部16列8行，下半部16列8行，组合起来就是16*16点阵的汉字。

不知道你用的是12864是什么控制芯片的？

你说的是半角字符？16*8的？

汉字（全角字符）是16*16的。

ID:138194 · 发表于 2016-12-5 17:46

汉字的大小可以改吗？
比如说是20*20；30*30的。是不是只能通过取模以图片的形式显示出来
显示图片的地址是怎么一回事？？？
谢谢！！！！

凡是LCD自带的汉子库，基本上都是16*16点阵的汉字。如果用绘图模式可以改其他的。但是每列8个点（一个字节）是不容易改的。当然，多余的闲置是可以的。

我推荐的所有案例都是带proteus仿真的，而proteus元件库中没有带汉字的12864芯片，没法提供不带汉字库的proteus仿真案例。但电路、程序和编程思路是可参考的。
