以前我修改了u8glib，使其支持ks0107/0108  让arduino u8glib支持ks0107/0108芯片组 192X64液晶 http://bbs.mydigit.cn/read.php?tid=1504464；
虽然u8glib支持很多的芯片、而且用C++引用和定制方法简单，但所有应用代码需放在loop中，这种构架更适应于无控制芯片的LCD；

因此，我还试用了另外一个库：GLCD，功能并不差，只是支持的芯片少。但支持ks0107/0108；因此我稍加修改，就支持19264了，也非常好用；

最近几天，有坛友询问ks0107/0108  19264三屏三片选驱动，我再次研究了一下该库，其实其核心代码也支持三屏三片选，因此为坛友写了个三屏三片选的配置文件，同时也放在坛里供需要的朋友，如需要进行其它移植和配置，这里附个简明的教程：

原移植和配置步骤：
一针对jd19264 M64/128板子并按照说明增加了下述两个文件：

   1   3屏2片选驱动配置文件：用原始文件 src/config/ks0108_Panel.h复制副本并修改而成：
          src/config/ks0108-192x64_Panel.h
      2   对M4/128特定板子的连接方式配置：用src/config/ks0108_Mega.h复制副本并修改而成：
                 src/config/ks0108_m64128.h

二修改src/glcd_Config.h 增加相应调用 ks0108-192x64_Panel.h 的选项
   第67行去除注释 // 这样就能调用 config/ks0108-192x64_Panel.h

三说明，在ks0108-192x64_Panel.h line 139～149 增加了根据定义__AVR_ATmega128__或__AVR_ATmega64__，自动装入ks0108_m64128.h的程序行，如果在其它板子如 1280/2560/644/644P等，则修改或添加相应的硬件连接文件；

以上两个文件是我以前针对 M64/128 JD19264写的文件，硬件不是这个条件的话，请自行修改；

配置自己的硬件环境实例:  （ks0108芯片  19264 三屏三片选）
    增加了一个文件：拷贝合适的配置文件ks0108_Panel.h副本，并更名为 ks0108-192x64_3cs.h
    line 42 修改为三片选  #define NBR_CHIP_SELECT_PINS   3

使用：
  1  修改src/glcd_Config.h
     第67行加注释 // 这样就能不会调用 config/ks0108-192x64_Panel.h
     第68行去除行首注释 // 这样就能调用 config/ks0108-192x64_3cs.h（这是我修改好的）
     其它的参数，均需要按实际情况设置，其中的说明很详细的。修改没有多大的困难。

  2 根据你具体连接的板子，修改ks0108_m64128.h 文件（或新建一个其它名称的）：
    主要有：
       line 28~30 数据端口直接输出（速度快）

       如未定义数据端口，则需要对 d0～d7 分别定义 (line 32~41)
       对2cs 脚定义（line 46～47）
       在 ks0108-192x64_3cs.h 中已定义NBR_CHIP_SELECT_PINS   3
       所以还需要在line 50 定义片选3脚号  glcdCSEL3
       定义 RW DI EN 脚号，line 57～59
       如有reset脚可控，在line 61
       如有背光可控在line 66

后记：
  我在ks0108-192x64_Panel.h 42行修改为：
#ifndef NBR_CHIP_SELECT_PINS
  #define NBR_CHIP_SELECT_PINS   2
#endif
这样 ks0108缺省2片选，如在编译环境有编译选项：
  -DNBR_CHIP_SELECT_PINS＝3
选择三片选

或修改为：
#ifndef NBR_CHIP_SELECT_PINS
  #define NBR_CHIP_SELECT_PINS   3
#endif
就变成缺省3片选了。
