十五、在屏幕上显示字符

　　显示字符需要先实现绘点功能，然后用取模工具对需要显示的字符取模，我用的取模工具为PCtoLCD2002，设置如下图：

封装的函数最好比较容易使用，最好能选择字体，具体细节再此不详述，直接附上程序。

16     sudo cp $(OBJ) ../../rootfs/ho

附上显示效果：

我在程序中实现了16,24,32,48,64这5种字体，支持的字符为“0123456789-: ”这13个字符，因为只要显示时间，所以就只实现了这13个字符，需要实现其他字符的话只需要修改对应的字体文件就可以了。需要支持其他字体也很方便，在draw.c第20行后面声明新字体的绘制函数，并在__g_draw_font_tab数组中将绘制字体的函数与相应字体大小关联起来。在draw.h第15行中的枚举类型中加入字体大小，需要注意的是字体大小一定要是偶数。

十五、在屏幕上显示字符的相关文章

汇编一点点提高3——键盘输入8位二进制数，存入NUM单元，并在屏幕上显示对应的16进制数

此程序要注意一下几点: 1.dos1号功能--带回显的键盘输入,自动存入al 2.dos7号功能--不带回显的键盘输入,自动存入al,若要在屏幕中显示要调用DOS2号功能 3.将输入的多个二进制数转换为ASCII码 input:  mov ah,1  int 21h  add bl,bl  cmp al,'1'  jnz P1  inc bl  P1: dec ch  jnz input 4.换行子程序: newline: mov ah,2 mov dl,13 int 21h mov ah,2

在屏幕上显示日志的Android类库

Galgo是Android日志类库,用于在屏幕上显示应用的日志信息.这对于测试人员和开发人员非常有用,可以根据屏幕上的日志文件了解应用出现BUG时发生的事情. 可以定义屏幕上显示日志的背景颜色.文本颜色.文本大小和日志显示的行数. https://github.com/inaka/galgo public class ExampleActivity extends Activity { @Override protected void onCreate(Bundle savedInstanceS

46.编写程序在屏幕上显示如下图形

1 2 3 4 55 1 2 3 44 5 1 2 33 4 5 1 2 2 3 4 5 1 (1)运用循环嵌套,并设置中间变量转换 //1.新建一个数组//2.输入内容并存储//3.输出结果 #include<iostream> using namespace std; int main() { int temp; int a[5]={1,2,3,4,5}; for(int m=0;m<5;m++) { cout<<a[m]<<" "; }

怎样在屏幕上显示多个alv

本文解说怎样在屏幕上显示多个alv. 实现这种需求关键是下面几点(举例:在屏幕上显示4个alv): 1.须要定义4个alv control 2.由于有4个alv control,于是就须要定义4个容器装这4个控件 3.为了合理布局这4个容器,就要将这4个容器嵌入另外一个splitter 容器中 4.可是splitter容器又仅仅能置入其它容器中,那么就须要再定义一个容器 总之,须要3层容器和1层控件,总共要定义6个容器和4个控件 5.最里面的容器应该是cl_gui_custom_containe

汇编：有关在屏幕区显示字符的四种方法

李忠老师的<x86汇编语言:从实模式到保护模式>中第五章到第七章的部分,每一章在讲述知识点的同时,分别使用了三种不同的显示字符的方法,加上调用BIOS的10h中 断的方法,这里做出一次简单梳理: 一:第五章,最基础的直接用mov 的方法 代码如下: 1 ;代码清单5-1 2 ;文件名:c05_mbr.asm 3 ;文件说明:硬盘主引导扇区代码 4 ;创建日期:2011-3-31 21:15 5 6 mov ax,0xb800 ;指向文本模式的显示缓冲区 7 mov es,ax 8 9 ;以下显

在开发板上显示字符和中文

我们在写lcd驱动程序时,测试时可以在lcd上显示信息,那么他怎么能显示出信息呢,内核里有字符点阵编码,我们在内核里打开字符编码,可以看到很多字符点阵也称为字体.下面我们来自已写一个应用程序在lcd显示屏上显示字母以及显示中文.字符编码 在前面有一个随笔里有写,对于英文字母,用ascii码即可,那么如果我们要显示中文的话应该是要用到汉字库编码即GBK编码表,下面来写一段程序来试验和理解如何在开发板的lcd上显示. 一.首先我们要获得lcd的信息,例:固定信息和可变信息等 这些我们都需要知道可以操
