key code 组合键原理

key code 组合键原理键码组合键是指按下多个键盘上的按键来完成某个特定操作或触发某个功能。

在计算机操作中，键码组合键起到了非常重要的作用，可以提高操作效率和便捷性。

下面我将介绍一些常见的键码组合键及其原理。

1. Ctrl + C/V/XCtrl键位于键盘左下角，通过与其他按键组合使用可以实现不同的功能。

Ctrl + C用于复制选中的内容，Ctrl + V用于粘贴复制的内容，Ctrl + X用于剪切选中的内容。

这些组合键的原理是，当按下Ctrl键的同时再按下相应的字母键，计算机会识别到这个组合，并执行相应的操作。

2. Alt + TabAlt键位于键盘左下角，Tab键位于键盘上方的第三行。

Alt + Tab组合键用于在多个打开的窗口之间切换。

按下Alt键不放，然后反复点击Tab键，可以在不同的窗口之间快速切换。

这个组合键的原理是，当按下Alt键的同时再按下Tab键，计算机会显示出所有打开的窗口，并在按下Tab键的同时切换焦点。

3. Ctrl + Z/YCtrl + Z用于撤销上一步操作，Ctrl + Y用于恢复撤销的操作。

这些组合键的原理是，计算机会将每一步的操作都保存在内存中，当按下Ctrl + Z时，计算机会从内存中找到上一步的操作，并执行撤销。

而当按下Ctrl + Y时，计算机会从内存中找到已撤销的操作，并执行恢复。

4. Ctrl + Shift + EscCtrl + Shift + Esc组合键用于打开任务管理器，可以查看当前正在运行的程序和进程，并进行相应的管理。

这个组合键的原理是，当按下Ctrl键和Shift键的同时再按下Esc键时，计算机会识别到这个组合，并打开任务管理器。

5. Ctrl + Alt + DelCtrl + Alt + Del组合键用于强制关闭当前程序或重启计算机。

这个组合键的原理是，当按下Ctrl键和Alt键的同时再按下Del键时，计算机会执行相应的操作。

在Windows系统中，这个组合键还有其他作用，比如打开安全选项等。

键盘扫描码——精选推荐

键盘扫描码
键盘上除了ASCII码外，还有非ASCII码(如左移键“←”对应的编码)，叫扩充键盘码。

我们把扩充键盘码放在高八位，ASC II码放在低八位所组成的代码称为扫描码。

对于某一特定的扫描码，若其低8位不为零，则此8位就是相应字符的ASCII码值；若低8位是零，则高8位是扩充键盘码，需要再读取人第二个字节，根据它的值来判断它是那一个功能键。

下表给出了单功能键和组合功能键的键值，表中代码系指第二个字节键值的十进制数。

例如，“←”的扫描码低8位应为零，而高8位是0x4b，所以，“←”键的扫描码为O x4b00；而“回车键”有对应的ASCII码，故其扫描码的低8位是回车键的ASCII码值0xod。

测试键盘扫描码
调用标准库函数b ioskey()读取键盘扫描码。

注意要使用b io skey()函数，应在文件头部加上#includ e “b ios.h”。

函数b io skey()的功能是用于识别用户按键和获得按键值。

函数原
型是：
int b ioskey(int cmd)；
在<b ios．h>中定义，在使用它时，应用include命令将b ios．h文件包含进来。

其中参数cmd可取值0或1。

①当cmd=1时，检测键盘是否有击键，如果没有击键，函数将返回0，否则返回非零；
②当cmd=0时，返回从键盘输入的扫描码。

语句key=b ioskey(0)；读取键盘输入的扫描码，并存储在变量k ey 中。

键盘扫描码

键盘上的每一个键都有两个唯一的数值进行标志。

为什么要用两个数值而不是一个数值呢？这是因为一个键可以被按下，也可以被释放。

当一个键按下时，它们产生一个唯一的数值，当一个键被释放时，它也会产生一个唯一的数值，我们把这些数值都保存在一张表里面，到时候通过查表就可以知道是哪一个键被敲击，并且可以知道是它是被按下还是被释放了。

这些数值在系统中被称为键盘扫描码2扫描码大全扫描码键0x011b ESC0x3b00 F10x3c00 F20x3d00 F30x3e00 F40x3f00 F50x4000 F60x4100 F70x4200 F80x4300 F90x4400 F10主键盘区:0x2960 ~0x0231 10x0332 20x0433 30x0534 40x0635 50x0736 60x0837 70x0938 80x0a39 90x0b30 00x0c2d -0x0d3d =0x2b5c \0x0e08 退格键0x0f09 Tab0x1071 q0x1177 w0x1265 e0x1372 r0x1474 t0x1579 y0x1769 i0x186f o0x1970 p0x1a5b [0x1b5d ]0x1e61 a0x1f73 s0x2064 d0x2166 f0x2267 g0x2368 h0x246a j0x256b k0x266c l0x273b ;0x2827 '0x1c0d 回车0x2c7a z0x2d78 x0x2e63 c0x2f76 v0x3062 b0x316e n0x326d m0x332c ,0x342e .0x352f /0x3920 空格键0xe05b 左Win0xe05c 右Win0xe05d Menu右边数字键盘:0x5200 Insert0x4700 Home0x4900 Page UP 0x5300 Delete0x4f00 End0x5100 PageDown 0x4800 上箭头0x4b00 左箭头0x5000 下箭头0x4d00 右箭头0x352f /0x4a2d - (注意,这是数字键盘的)0x4737 70x4838 80x4939 90x4b34 40x4c35 50x4d36 60x4e2b +0x4f31 10x5032 20x5133 30x5230 00x532e Del通过PC机键盘输入汉字时，其中经过多次的代码转换：用户---汉字输入码---键盘---键盘扫描码---BIOS键盘驱动程序----ASCII码----汉字输入软件----汉字内码。

PC键盘扫描码

O：就是利用bioskey()得到的值。

参数为0时，bioskey()的返回值如果低八位非0，表示按下了普通键；如果低八位为0，表示按下了功能键。

参数为1时，检测有没有键被按下，如果返回值为0，表示没有键按下，相反有键按下。

参数为2时，表示获取变换键的状态，哪些是变换键呢？变换键包括双态键和控制键，双态键就是num lock、scroll lock、insert和caps lock，控制键就是左右shift、ctrl和alt，返回值的低八位反映了这些变换键的状态：0x01 右边shift0x10 scroll lock打开0x02 左边shift0x20 num lock打开0x04 ctrl键0x40 caps lock打开0x08 alt键0x80 insert打开其实bioskey直接调用bios的int 16h键盘I/O中断，直接就是int 16h 的完整翻版。

键盘扫描码大全对程序进行键盘控制时,往往要用到一些键的扫描码,以前每次用时都得先扫下试试,实在麻烦,今天又搞了个小程序,用到了扫描码,索性整了个测试程序,把所有键的扫描码全存入一个文件啦,以便以后编程时使用.在此跟大家分享一下,虽然得来非常容易,但至少可以免得大家都像我以前那样用时再查扫描码键0x011b ----- ESC0x3b00 ----- F1 0x3c00 ----- F20x3d00 ----- F30x3e00 ----- F40x3f00 ----- F50x4000 ----- F60x4100 ----- F70x4200 ----- F80x4300 ----- F90x4400 ----- F10主键盘区:0x2960 ----- ~0x0231 ----- 10x0332 ----- 20x0433 ----- 30x0534 ----- 40x0635 ----- 50x0736 ----- 60x0837 ----- 70x0938 ----- 80x0a39 ----- 90x0b30 ----- 00x0c2d ----- -0x0d3d ----- =0x2b5c ----- \0x0e08 ----- 退格键0x0f09 ----- Tab0x1071 ----- q0x1177 w0x1265 e0x1372 r0x1474 t0x1579 y0x1675 u0x1769 i0x186f o0x1970 p0x1a5b [0x1b5d ]0x1e61 a0x1f73 s0x2064 d0x2166 f0x2267 g0x2368 h0x246a j0x256b k0x266c l0x273b0x2827 '0x1c0d 回车0x2c7a z0x2d78 x0x2e63 c0x2f76 v0x3062 b0x316e n0x326d m0x332c ,0x342e .0x352f /0x3920 空格键右边数字键盘:0x5200 Insert0x4700 Home0x4900 Page UP0x5300 Delete0x4f00 End0x5100 PageDown0x4800 上箭头0x4b00 左箭头0x5000 下箭头0x4d00 右箭头0x352f /0x372a *0x4a2d - (注意,这是数字键盘的) 0x4737 70x4838 80x4939 90x4b34 40x4c35 50x4d36 60x4e2b +0x4f31 10x5032 20x5133 30x5230 00x532e DelCtrl+字母:在字母扫描码的基础上减去0x0060alt+字母: 在字母的基础上,把最后两位变成00shift+字母:在字母的基础上减去0x0020比如: a----0x1e61 Ctrl+a----0x1e01 Alt+a-----0x1e00b----0x3062 Ctrl+b----0x3002 Alt+b-----0x3000另加: Ctrl+Enter: 0x1c0a可以直接用一个程序查看的，很简单的#include “stdio.h”#include “bios.h”void main(void){int key, modifiers;while ((key=bioskey(0)) != 0 && key!=0x11b){printf("0x%x \n",key);}}*********************************************************** ********************上面列出的编码中，前面两位是“扫描码”，后面两位是ASCII码，合起来是所谓的“键盘码”比如，小键盘的数字键扫描码和大键盘的数字键是不同的，而后两位是一样的，因为那个是它们共用的ASCII码，下面就是扫描码的列表Keyboard Scan Codes (Numerical Order)---------------+---------------+---------------+---------------+---------------HEX DEC keys |HEX DEC keys |HEX DEC keys |HEX DEC keys |HEX DEC keys---------------+---------------+---------------+---------------+---------------|10 16 Q |20 32 D |30 48 B|40 64 F601 1 ESC |11 17 W |21 33 F |31 49 N |41 65 F702 2 1 |12 18 E |22 34 G |32 50 M |42 66 F803 3 2 |13 19 R |23 35 H |33 51 , |43 67 F904 4 3 |14 20 T |24 36 J |34 52 . |44 68 F1005 5 4 |15 21 Y |25 37 K |35 53 / |45 69 Num06 6 5 |16 22 U |26 38 L |36 54 R Shift |46 70 Scroll07 7 6 |17 23 I |27 39 |37 55 PrtSc |47 71 Home08 8 7 |18 24 O |28 40 ' |38 56 Alt |48 72 Up09 9 8 |19 25 P |29 41 ` |39 57 Space |49 73 PgUp0A 10 9 |1A 26 [ |2A 42 L Shift |3A 58 Caps |4A 74 -0B 11 0 |1B 27 ] |2B 43 \ |3B 59 F1 |4B 75 Left0C 12 - |1C 28 |2C 44 Z |3C 60 F2 |4C 76 Center0D 13 = |1D 29 CTRL |2D 45 X |3D 61 F3 |4D 77 Right0E 14 bs |1E 30 A |2E 46 C |3E 62 F4 |4E 78 +0F 15 Tab |1F 31 S |2F 47 V |3F 63 F5 |4F 79 End---------------+---------------+---------------+---------------+---------------50 80 Down | | | |51 81 PgDn | | | |52 82 Ins | | | |53 83 Del | | | |---------------+---------------+---------------+---------------+---------------Keyboard Scan Codes (Read from Port HEX 60 = DEC 96) (Keyboard Layout)Top number ...

key code 组合键原理

key code 组合键原理
Key Code 组合键原理
一、概述
Key Code，也称为键码或键值，是一个在计算机编程中广泛使用的概念。

它代表了键盘上每个键的唯一标识符，用于识别和区分不同的按键输入。

组合键则是通过同时按下多个键来实现特定的功能或操作。

了解Key Code组合键的原理，有助于更好地理解和使用键盘输入，提高工作效率。

二、Key Code的原理
Key Code的原理基于键盘矩阵。

键盘矩阵由行和列组成，每个键都位于行和列的交叉点上。

当按下某个键时，键盘控制器会检测到该键所在的行和列被按下，从而确定被按下的键的Key Code。

不同的键盘布局和设计可能会有不同的Key Code分配。

因此，在实际编程中，为了实现跨平台的键盘输入兼容性，通常需要使用更为抽象的键码库，如SDL、GLFW等。

这些库提供了一套统一的接口，用于处理不同的键盘布局和键码映射。

三、组合键的原理
组合键的实现原理相对简单。

当用户按下某个组合键时，键盘会将所有按下的键的Key Code发送给计算机。

应用程序通过检测这些Key Code的组合来判断是否按下了组合键，并执行相应的操作。

在大多数操作系统中，组合键的具体实现方式可能会有所不同。

例如，在Windows中，可以使用WinAPI函数来检测组合键的状态；在Linux中，可以使用Xlib等库来处理组合键的输入。

总之，了解Key Code和组合键的原理有助于更好地利用键盘输入，提高工作效率。

在实际应用中，需要结合具体的平台和开发环境，选择合适的键盘输入处理方式。

c语言键盘扫描码大全对程序进行键盘控制时,往往要用到一些键的扫描码,以前每次用时都得先扫下试试,实在麻烦,今天又搞了个小程序,用到了扫描码,索性整了个测试程序,把所有键的扫描码全存入一个文件啦,以便以后编程时使用.在此跟大家分享一下,c语言键盘扫描码扫描码键 0x011bESC 0x3b00F1 0x3c00F2 0x3d00F3 0x3e00F4 0x3f00F5 0x4000F6 0x4100F7 0x4200F8 0x4300F9 0x4400F10 主键盘区: 0x2960~ 0x02311 0x03322 0x04333 0x05344 0x06355 0x07366 0x08377 0x09388 0x0a399 0x0b300 0x0c2d- 0x0d3d= 0x2b5c\ 0x0e08退格键 0x0f09Tab 0x1071q 0x1177w 0x1265e 0x1372r 0x1474t 0x1579y 0x1675u 0x1769i 0x186fo 0x1970p 0x1a5b[ 0x1b5d] 0x1e61a 0x1f73s 0x2064d 0x2166f 0x2267g 0x2368h 0x246aj 0x256bk 0x266cl 0x273b; 0x2827’ 0x1c0d回车 0x2c7az 0x2d78x 0x2e63c 0x2f76v 0x3062b 0x316en 0x326dm 0x332c, 0x342e. 0x352f/ 0x3920空格键右边数字键盘: 0x5200Insert 0x4700Home 0x4900Page UP 0x5300Delete 0x4f00End 0x5100PageDown 0x4800上箭头 0x4b00左箭头 0x5000下箭头 0x4d00右箭头 0x352f/ 0x372a* 0x4a2d- (注意,这是数字键盘的) 0x47377 0x48388 0x49399 0x4b344 0x4c355 0x4d366 0x4e2b+ 0x4f311 0x50322 0x51333 0x52300 0x532eDel 以上就是由为您提供的c语言键盘扫描码，希望给您带来帮助! 。

小键盘的原理

系统扫描码在我们通常所使用的pc机上，系统（BIOS， linux内核）处理的并不是键盘扫描码，而是系统扫描码。而键盘扫描码到系统扫描码的转换通常都是由硬件（如PC键盘接口模块 8042）完成。系统扫描码与键盘扫描码除了每个键的代码不同外，最大的差别是把键盘放下时产生的两个键盘扫描码（共两字节）转换为1个字节的系统扫描码表示。如‘A’被键释放时，发送键盘扫描码为：F0H，1CH，相应的系统扫描码为9E。
实现按“1”，在屏幕上显示“HELLO”
其命令如下：
#include <sys/types.h> #include <sys/stat.h> #include <fcntl.h> #include <sys/socket.h> #include <syslog.h> #include <signal.h> #include <errno.h> #include <unistd.h> #include <stdio.h> #include <stdlib.h> #include <sys/socket.h> #include <syslog.h> #include <signal.h> #include "led_ioctl.h" #define NOKEY 0
键码内核中为了方便键盘按键的处理，把系统扫描码对应成键码（keycode）。键码在1－ 128之间（一般的键盘为104键），这样键码就可用7位来表示键盘上某个键（内核中用键码字节的高位表示此键是按下还是松开）。
2．键盘按键值的获取 PC机的PS2键盘按键太多，若是采用轮询方式将浪费CPU时间。因此采用的是中断方式。通用的键值获取流程如下：
