一 开源库简介与移植

        最近一个项目需要用12864屏幕呈现一组较为复杂的菜单界面，本着不重复造轮子的原则找到了SimpleGUI开源库。

        开源地址：SimpleGUI: 一个面向单色显示屏的开源GUI接口库。

        SimpleGUI是一款针对单色显示屏设计的接口库。相比于传统的GUI框架，SimpleGUI的出发点，是在一个单色显示器上，以尽可能少的消耗、尽可能多且直观的表达需要的内容，为此，SimpleGUI抛弃了诸如图层、遮罩、阴影、非等宽字体等高级的、复杂的操作，力求以简单快捷、易于操作的方式，使开发者尽快实现自己需要的功能需求。 同时在满足基本绘图需求的前提下，SimpleGUI还提供了一套被称为HMI的交互引擎，用于统合用户交互、数据处理和屏幕内容绘制与更新，提供了一种简明、易组织、易拓展、低消耗的交互系统。

       

        开源库的模拟器部署以及嵌入式移植参考前文：

二 精简字库的制作

        如果片上资源足够，可以使用全中文字库。以SimpleGUI默认的12像素字体为例，每个半角字符需要消耗6*2字节，全角字符需要消耗12*2字节，那么整个GB2312字库对Flash的消耗为：

(6*2)*96+(12*2)*3755+(12*2)*3008 = 1152 + 90120 + 72192 = 163464 Bytes

        约164KB的Flash消耗对于单片机来说还是非常可观的，如果还需要其他不同大小的字体，空间资源需求还要成倍增加，所以这种时候，通常就要使用外部字库了。

        但事实上，很多时候，界面上的文字都是既定好的，不需要动态的变化，这也就决定了整个系统中可能仅仅就需要使用少数的几个字符。这时候如果还要去设计外部字库显然对软硬件成本都是一种浪费，精简字库消耗才是正途。   通过前文的说明，字符和字符串的编码，说到底不过就是从字符编码到字库索引上的一种算法表达，精简字库，说到底也是从这一方面着手，删除掉字库中用不到的文字和符号，重新定义编码和索引，字库的精简就完成了。

        基于以上思想，精简字库首先要列出整个目标系统中所有可能用到的文字，然后进行去重，提炼出目标系统中用到的所有汉字。然后给这些汉字进行重新编码，简而言之就是进行简单排序，然后重新编号，这个编号就是新规定的字符编码。最后，用这个新的编码重新去对字符串进行编码，这样就完成了字库的精简了。

        举个例子，我想在12864屏幕上显示一首词《虞美人·春花秋月何时了》：

春花秋月何时了？往事知多少。
小楼昨夜又东风，故国不堪回首月明中。
雕栏玉砌应犹在，只是朱颜改。
问君能有几多愁？恰似一江春水向东流。

【1】开源库的作者提供了一个小工具（MinimumFontLib: 一个用于精简单色点阵字库数据的工具），用来文字的提取和重编码，省去了大量的人工工作，非常方便。将所用到的文字粘进去，点击提取和重编码，得到重新排序后的文字和重编码之后的代码：

【2】将重编码后的代码（上图中的Record Text）替换到 GUI\src\SGUI_FontResource.c 文件中默认 SGUI_DEFAULT_FONT_16 字库的汉字编码数组 s_arrUnicodeTable 中：

};

【3】将重新排序后的文字（上图中的Extracted Text）用字库处理软件（推荐： PCtoLCD2002完美版 ）处理成C51形式：

【4】将上一步生成的内容直接复制替换到 GUI\src\SGUI_FontResource.c 文件中默认 SGUI_DEFAULT_FONT_16 字库的字符库数组 SGUI_FONT_H16 中（注意：中文是从第95下标往后添加）：

        至此，精简字库准备完成，接下来是字库的使用。

三 精简字库的调用

【1】新建一个头文件并转化成 UTF-8 编码格式（我这边命名为 Gui_Text_UTF8.h ），里面通过宏定义，管理程序中用到的所有中文文本内容。好处是该头文件可以随时替换为其他的编码格式：

#ifndef __GUI_TEXT_UTF8_H_
#define __GUI_TEXT_UTF8_H_/* Screen 1: List Components. */
#define TEXT_TEST   ("春花秋月何时了?往事知多少.小楼昨夜又东风,故国不堪回首月明中.雕栏玉砌应犹在,只是朱颜改.问君能有几多愁?恰似一江春水向东流.")/* Screen 2: Basic Paint*//* Screen 3: Text demo*//* Screen 4: Variable box. *//* Screen 5: Realtime graph. *//* Screen 6: Variable box. *//* Screen 7: Notice box. */#endif

【2】主函数中调用（例子中使用多行文本显示函数 SGUI_Text_DrawMultipleLinesText ，该函数中的内容遇到设定的空间边界自动换行）：

/**************************************************************************
* 函数名称： Gui_Task
* 功能描述： 液晶显示子任务
**************************************************************************/
SGUI_SCR_DEV disp_dev;    //中文屏设备源
#define     BMP_DATA_BUFFER_SIZE    (512)
SGUI_BYTE                   s_pBmpDataBuffer[BMP_DATA_BUFFER_SIZE];void Gui_Task(void)
{SGUI_RECT disp_area;SGUI_POINT disp_offs;//点阵屏初始化/配置命令/清屏LDZ_Init();LDZ_Cfg();LDZ_Clear();//设备内存地址初始化SGUI_SystemIF_MemorySet(&disp_dev, 0x00, sizeof(disp_dev));//一些相关初始化配置disp_area.iX = 0;disp_area.iY = 0;disp_area.iWidth = 128;disp_area.iHeight = 64;disp_offs.iX = 0;disp_offs.iY = 0;disp_dev.stSize.iWidth = 128;disp_dev.stSize.iHeight = 64;/* Initialize interface object. */disp_dev.fnSetPixel = LDZ_SetPixel;disp_dev.fnClear = LDZ_Clear;disp_dev.fnSyncBuffer = LDZ_Refresh;disp_dev.stBuffer.pBuffer = s_pBmpDataBuffer;disp_dev.stBuffer.sSize = BMP_DATA_BUFFER_SIZE;//...while(1){//显示多行文本disp_area.iX = 0;disp_area.iY = 0;disp_area.iWidth = 128;disp_area.iHeight = 64;SGUI_Text_DrawMultipleLinesText(&disp_dev, TEXT_TEST, &SGUI_DEFAULT_FONT_16, &disp_area, 0, SGUI_DRAW_NORMAL);LDZ_Refresh();os_dly_wait(50);}
}

【3】实际显示效果如下：

【注意】：有的时候keil工程中会因为UTF-8兼容问题报错“error:  #8: missing closing quote”，解决办法如下（网上也有不少帖子记录这个问题）：

方法一：在KEIL中魔术棒Options for Target ‘Flash’ -> C/C++ -> Misc Controls 中添加 --locale=english --no-multibyte-chars

方法二：将格式由UTF8替换为UTF8-BOM
