中文点阵字库的使用方法(安富莱电子)

一种lvgl使用点阵字库的方法一种lvgl使用点阵字库的方法介绍LVGL是一个开源的嵌入式图形库，提供了丰富的图形用户界面（GUI）功能。

在开发嵌入式设备的过程中，通常需要使用字库来显示文本内容。

本文将介绍一种使用点阵字库在LVGL中显示文本的方法。

选择点阵字库在使用LVGL显示文本之前，首先需要选择适用的点阵字库。

点阵字库是由一系列的点阵字符组成的，每个字符由一定数量的点阵组成，使用这些点阵可以绘制出字符的形状。

可以根据需求选择不同的点阵字库，如宋体、华文楷体等。

准备点阵字库文件选择好点阵字库后，需要准备相关的字库文件。

点阵字库文件通常以字库名称作为文件名，并以扩展名为.bdf或.c的格式保存。

如果字库文件没有提供，可以使用字库生成工具生成对应的字库文件。

导入点阵字库文件在LVGL中导入点阵字库文件非常简单。

可以按照以下步骤进行操作：1.将点阵字库文件复制到LVGL项目的字库文件夹中。

2.在LVGL的配置文件中添加对应的字库文件路径。

3.在代码中引入相关的头文件，并使用lv_font_add()函数将字库添加到LVGL中。

使用点阵字库绘制文本完成点阵字库的导入后，就可以使用它来绘制文本了。

可以按照以下步骤进行操作：1.创建LVGL的文本对象，使用lv_label_create()函数。

2.使用lv_label_set_text()函数设置文本内容。

3.使用lv_label_set_style()函数设置文本的样式，如字体、颜色等。

4.将文本对象添加到LVGL的显示对象中，使用lv_obj_add_child()函数。

示例代码下面是一个简单的示例代码，演示了如何使用点阵字库在LVGL中显示文本：#include "lvgl/"#include "fonts/arial_" // 导入点阵字库文件int main(void) {lv_init();lv_disp_drv_t disp_drv;lv_disp_drv_init(&disp_drv);// 初始化显示设备lv_disp_t *disp = lv_disp_drv_register(&disp_drv);// 注册显示设备lv_obj_t *label = lv_label_create(lv_scr_act(), NUL L);// 创建文本对象lv_label_set_text(label, "Hello LVGL!");// 设置文本内容lv_label_set_style(label, LV_LABEL_STYLE_MAIN, &aria l_16);// 设置文本样式为点阵字库arial_16lv_obj_align(label, NULL, LV_ALIGN_CENTER, 0, 0);// 居中对齐文本对象while (1) {lv_task_handler();// LVGL任务处理}return 0;}总结本文介绍了一种在LVGL中使用点阵字库的方法。

第18章汉字显示方式一（FontCvt的使用）本期教程主要跟大家介绍官方的小工具Font Converter的使用方法，使用官方的字体转换工具，字体的显示效果要比网上那些针对UCGUI设计的字体生成工具好非常多。

4位抗锯齿的显示效果更是非常棒。

在开头先跟大家强调两点，一个是这个字体小工具必须的使用STemWin软件包里面的，SEGGER官网下载的和MDK安装目录里面带的都是评估版，另一点是在教程中我会要求大家将要显示汉字的C文件转换为UTF-8编码，我仅仅是指的将这个显示汉字的C文件转换为UTF-8编码，这点要切记。

18. 1 使用FontCvt生成字库C文件的方法18. 2 在开发板上面实现中文显示18. 3 总结18.1使用FontCvt生成字库C文件的方法我们先讲如何用这个软件生成部分的汉字数据，这里就以“安富莱电子”五个字进行说明。

18.1.1第一步：打开选择Standard，16bit unicode18.1.2第二步：打开选择字体和字体大小18.1.3第三步：选择禁止所有的字符18.1.4第四步：用unicode软件转换函数用中文转unicode的小软件得到“安福莱电子”这5个字的unicode编码我这里在百度上面找了一个网页应用。

18.1.5第五步：在FontCvt上使能这个五个字的编码在Font Converter软件上面使能这个五个字的unicode编码，以“安”字为例它的unicode编码是5b89，这里有两种办法找这个字。

方法一：直接的在软件里面查找，根据左边的unicode编码。

方法二：通过限制范围查找。

18.1.6第六步：然后点击保存为C文件要将前面的五个字全部找到并使能以后再做保存。

18.2在开发板上面实现中文显示下面我们用18.1小节讲的汉字生成方式生成7中类型的字体。

前三种是Standard的宋体，大小是16，36和72.第四种是144*144点阵的，有没有这么大的字体，需要手动往大小选项里面填写144，并选择右侧的Pixels。

2009年06月03日下午 04:27一.实验要求编程实现中英文字符的显示。

二.实验目的1.了解LED点阵显示的基本原理和实现方法。

2.掌握三.实验电路及连线点阵显示模块WTD3088的（红色）列输入线接至内部LED的阴极端，行输入线接至内部LED的阳极端（若阳极端输入为高电平，阴极端输入低电平，则该LED点亮）。

发光点的分布如图22-0所示。

Fig 22-0 WTD3088 LED分布如图22-1示，本实验模块使用74LS374来控制列输入线的电平值。

将74LS374的某输出置0，则对应的LED阴极端被置低。

如图22-2示，本实验模块使用74LS273来控制行输入线，并通过9013提供电流驱动。

将74LS273的某输出置1，则对应的LED阳极端被置高。

每次系统重新开启或总清后，74LS273输出为全0，LED显示被关闭。

通过编程控制各显示点对应LED阳极和阴极端的电平，就可以有效的控制各显示点的亮灭。

Fig 22-1 LED模块及列扫描电路 Fig 22-2 行扫描电路Fig 22-3地址译码电路本实验模块使用4块WTD3088组成16×16点阵，以满足汉字显示的要求。

为了方便的控制四个单元，使用了一片74LS139译码，产生四个地址片选信号：CLKR1= CSLED，CLKR2= CSLED+1，用于行控制的两片74LS273；CLKC1= CSLED+2，CLKC2= CSLED+3，用于列控制的两片74LS374。

实验接线:按示例程序，模块的CSLED接51/96地址的8000H。

四.实验说明使用高亮度LED发光管构成点阵，通过编程控制可以显示中英文字符、图形及视频动态图形。

汉字点阵字库原理一、汉字编码1. 区位码在国标GD2312—80 中规定，所有的国标汉字及符号分配在一个94 行、94 列的方阵中，方阵的每一行称为一个“区”，编号为01 区到94 区，每一列称为一个“位”，编号为01 位到94位，方阵中的每一个汉字和符号所在的区号和位号组合在一起形成的四个阿拉伯数字就是它们的“区位码”。

区位码的前两位是它的区号，后两位是它的位号。

用区位码就可以唯一地确定一个汉字或符号，反过来说，任何一个汉字或符号也都对应着一个唯一的区位码。

汉字“母”字的区位码是3624，表明它在方阵的36 区24 位，问号“?”的区位码为0331，则它在03区3l位。

一级汉字16-55区二级汉字56-87区三级汉字1-9区空闲未用10-15区2. 机内码汉字机内码，又称“汉字ASCII码”，简称“内码”，汉字的机内码是指在计算机中表示一个汉字的编码。

机内码与区位码稍有区别。

如上所述，汉字区位码的区码和位码的取值均在1~94 之间，如直接用区位码作为机内码，就会与基本ASCII码混淆。

为了避免机内码与基本ASCII码的冲突，需要避开基本ASCII码中的控制码(00H~1FH)，还需与基本ASCII码中的字符相区别。

为了实现这两点，可以先在区码和位码分别加上20H，在此基础上再加80H(此处“H”表示前两位数字为十六进制数)。

经过这些处理，用机内码表示一个汉字需要占两个字节，分别称为高位字节和低位字节，这两位字节的机内码按如下规则表示：高位字节= 区码+ 20H + 80H(或区码+ A0H)低位字节= 位码+ 20H + 80H(或位码+ AOH)由于汉字的区码与位码的取值范围的十六进制数均为01H~5EH(即十进制的01~94)，所以汉字的高位字节与低位字节的取值范围则为A1H~FEH(即十进制的161~254)。

例如，汉字“啊”的区位码为1601，区码和位码分别用十六进制表示即为1001H，它的机内码的高位字节为B0H，低位字节为A1H，机内码就是B0A1H。

我们知道英文字母数量比较少，我们只要用一个字节（8位）就足以表达。

但是汉字非常多。

要怎么表达呢？前人采用的一个方法就是把ASCII码的高128位作为汉字的内码，低128位仍然作为英文字母的内码，然后用两个字节来表示一个汉字。

通过这个内码，我们可以获取汉字的字模信息。

然后再根据这些字模的信息，把相应的汉字显示出来。

二、什么是汉字字库？如何寻址？点阵字库其实就是按照汉字内码的顺序，把汉字的字模信息存起来。

16×16的点阵字库有94区，每个区有94个汉字的字模。

这样总的有94×94个汉字。

我们之前说了，一个汉字由两个ASCII扩展码构成。

第一个ASCII扩展码用来存放汉字的区码，第二个ASCII扩展码用来存放汉字的位码。

具体是这样的：第一个扩展ASCII码= 128 + 汉字的区码第二个扩展ASCII码= 128 +汉字的位码这样，如果我们用char HZ[2]来表示一个汉字。

则：区码= HZ[0] - 128位码= HZ[1] - 128这样，算出区位码之后，我们就可以用它在汉字库里面寻址找字模了。

具体的方式是：该汉字的偏移地址 = （区码-1）×94×一个字占用的字节数+位码×一个字占用的字节数这样我们就很容易的写出显示汉字字模的函数：INT8U *HZK = (INT8U *)0x801c0000; /* 汉字字库的存储地址*/INT8U *ASCII = (INT8U *)0x801fba00; /* ASCII码字库的存储地址 */INT8U const cmp_w[8]={128,64,32,16,8,4,2,1};/********************************************************************************** ************************* Function : DisplayHZ()** Description: 该函数用于在F DGK/GUI上显示一个汉字。

点阵字库HZ K12 H Z K16 H Z K24 ASC12 ASC16 简介及使用方法如何在嵌入式系统中使用大量的汉字和字符呢?DO S前辈们经过艰辛的努力，将制作好的字模放到了一个个标准的库中以免去后辈的麻烦，这就是点阵字库文件。

一般我们使用16*16的点阵宋体字库，所谓16*16，是每一个汉字在纵、横各16点的区域内显示的。

不过后来又有了HZK12、HZK24，HZK32和HZK48字库及黑体、楷体和隶书字库。

虽然汉字库种类繁多，但都是按照区位的顺序排列的。

前一个字节为该汉字的区号，后一个字节为该字的位号。

每一个区记录94个汉字，位号则为该字在该区中的位置。

因此，汉字在汉字库中的具体位置计算公式为：94*(区号-1)+位号-1。

减1是因为数组是以0为开始而区号位号是以1为开始的。

这仅为以汉字为单位该汉字在汉字库中的位置，那么，如何得到以字节为单位得到该汉字在汉字库中的位置呢？只需乘上一个汉字字模占用的字节数即可，即：(94*(区号-1)+位号-1)*一个汉字字模占用字节数，而按每种汉字库的汉字大小不同又会得到不同的结果。

以16*16点阵字库为例，计算公式则为：(94*(区号-1)+(位号-1))*32。

汉字库文该从该位置起的32字节信息即记录了该字的字模信息。

☆打印字库文件和HZK12如果你有UCDOS的HZK24S（宋体）、HZK24K（楷体）或HZK24H（黑体），你还可以使用不同字体的大字模汉字了。

HZK24系列是24*24的点阵字库，每字模占用3*24字节。

如果你按照HZK16的显示方法的话，你会看到......呵呵，字被放倒了。

这是因为该类字库与一般的汉字库不同，这类大字模汉字库是专供打印的打印字库，为了打印的方便将字模都放倒了，你使用时，只要将字模的位信息纵横转置显示即可。

例如你如果定义为mat[24][3]则应该这样输出：f or(i=0;i<24;i++)f or(j=0;j<24;j++)if((0x80>>i%8)&mat[j][i/8])/*转置显示*/putpixel(j+x,y+i,color);还有一类字库HZK12，虽然属于标准字库类型，但如果你将它的字模当作12*12位计算的话，根本无法正常显示汉字。
