键盘扫描码

键盘扫描码一. 键盘的构造及历史对于键盘，如果想要表示某个按键，硬件上对应着某个点，有两种方法。

一种是对于每个按键，都设计一个硬件的点。

一种是设计成矩阵式，即由多少行，多少列所组成。

举例说明：某个键盘一共需要35个按键。

前者是要设计35个硬件上的点。

后者只需要设计7行5列即可实现7×5=35个按键。

行列的矩阵式，比独立的点的方式，硬件上更容易实现。

矩阵式的键盘普通PC上的键盘，由于按键太多，为了之后的普及和通用性，要有个统一的标准，去定义哪个键值对应到键盘上的哪个按键。

因此，才会出现扫描码Scan Code。

二. 键盘中的扫描码Scan Code从按下一个键盘上的字母，到手松开，实际上对应着一个通码Make Code和一个断码Break Code，两者概念上都属于扫描码ScanCode。

对应的按下键的动作产生的键码叫做通码Make Code。

释放的时候电路被断开产生的键码叫做断码Break Code。

三. 扫描码集合Scan Code Set目前现存有3种Scan Code即，Scan Code Set1（第一种扫描码集合）。

Scan Code Set2。

Scan Code Set3。

四. 第一种扫描码集合Set1的Scan Code的Make Code和Break Code都是单字节。

Make code和Break Code的差别就在最高位，即Break code = make code + 0x80将make code的最高位置1就是Break Code。

五. 键盘常见流程（1）用户按下键盘上的某个键（2）键盘的硬件产生Scan Code，其中目前常见的AT键盘中用的是Set2的Scan Code。

按下是Make Code，释放是Break Code （3）键盘的控制器将Set2的Scan Code转化为Set1的Scan Code。

A. 此处是为了兼容旧的Scan Code Set1才去将Set2转为Set1。

PC键盘第二套扫描码集

PC键盘第二套扫描码集编程 2008-06-01 01:17 阅读1094 评论0字号：大中小来源：/web/pckey/scancode.htmPC键盘扫描码参考资料键盘的处理器如果发现有键被按下、释放、或按住键盘不放将发送扫描码的信息包到计算机，扫描码有两种不同的类：型通码和断码,当一个键被按下或按住，就发送通码，当一个键被释放就发送断码,每个按键被分配了唯一的通码和断码,这样主机通过查找唯一的扫描码就可以测定是哪个按键,通码和断码组成了键盘的扫描码集,有三套标准的扫描码集,分别是第一套、第二套和第三套，下面给出的现在通行的第二套扫描码集。

虽然多数按键只有一个字节宽，但也有少数扩展按键的通码是两字节或四字节宽，这类按键的通码第一个字节总是为E0h。

正如键按下通码就被发往计算机一样，只要键一释放断码也会被发送到计算机，每个键都有它自己唯一的通码和断码。

幸运的是，你不用总是通过查表来确定按键的断码，在通码和断码之间存在着必然的联系，多数断码有两字节长，其第一个字节是F0h 第二个字节是这个键的通码，扩展按键的断码通常有三个字节，它们前两个字节是E0h,F0h 最后一个字节是这个按键通码的最后一个字节，下面举一个例子，先列出了几个按键的通码和断码一个按键发送的例子（以按G键为例）:通码和断码是以什么样的序列发送到你的计算机，然后使得字符G出现在你的字处理软件里的呢，因为这是一个大写字母需要发生这样的事件次序:按下左Shift- 键-按下G键-释放G-键释放左Shift键，左Shift 键的通码12h，G键的通码34h G键的断码F0h 34h，左Shift键的断码F0h 12h 因此发送到你的计算机的数据应该是：12h 34h F0h 34h F0h 12h。

键盘码

2PS/2键盘的编码与命令集（1）PS/2键盘的编码现在PC机使用的PS/2键盘都默认采用第二套扫描码集。

该扫描码集可参考文献\[1\]。

扫描码有两种不同的类型：通码(make code)和断码(break code)。

当一个键被按下或持续按住时,键盘会将该键的通码发送给主机;而当一个键被释放时,键盘会将该键的断码发送给主机。

根据键盘按键扫描码的不同,在此可将按键分为如下几类：第一类按键,通码为1字节,断码为0xF0+通码形式。

如A键,其通码为0x1C,断码为0xF0 0x1C。

第二类按键,通码为2字节0xE0+0xXX形式,断码为0xE0+0xF0+0xXX形式。

如right ctrl键,其通码为0xE0 0x14,断码为0xE0 0xF0 0x14。

第三类特殊按键有两个,print screen键通码为0xE0 0x12 0xE0 0x7C,断码为0xE0 0xF0 0x7C 0xE0 0xF0 0x12; pause键通码为0x E1 0x14 0x77 0xE10xF0 0x14 0xF0 0x77,断码为空。

组合按键的扫描码发送按照按键发生的次序,如以下面顺序按左SHIFT+A键：1按下左SHIFT键,2按下A键,3释放A键,4释放左SHIFT键,那么计算机上接收到的一串数据为0x12 0x1C 0xF0 0x1C 0xF0 0x12。

在驱动程序设计中,就是根据这样的分类来对不同的按键进行不同处理的。

（2）PS/2键盘的命令集主机可以通过向PS/2键盘发送命令来对键盘进行设置或者获得键盘的状态等操作。

每发送一个字节,主机都会从键盘获得一个应答0xFA（“重发resend”和“回应echo”命令例外）。

下面简要介绍驱动程序在键盘初始化过程中所用的指令（详细键盘命令集见参考文献\[1\]）：0xED主机在本命令后跟随发送一个参数字节,用于指示键盘上num lock, caps lock, scroll lock led的状态;0xF3主机在这条命令后跟随发送一个字节参数来定义键盘机打的速率和延时;0xF4用于在当主机发送0xF5禁止键盘后,重新使能键盘。

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。

键盘扫描原理

键盘扫描原理
键盘扫描原理是指通过控制信号将按键状态传输到计算机的一种技术。

它主要分为两个步骤：键盘扫描和数据传输。

在键盘扫描过程中，计算机会发送扫描码（scan code）到键盘。

扫描码是一个8位的二进制数，用于唯一标识每个按键。

键盘内部有一个按键矩阵，当按键按下时，会触发相应的行和列连线，形成一个电路通路。

键盘通过轮询的方式扫描每个按键的状态，并生成扫描码。

一旦键盘生成了扫描码，它就会通过电缆传输给计算机。

数据传输的方式可以是串行还是并行，取决于键盘和计算机之间的连接方式。

对于串行传输，扫描码会被逐位地发送到计算机。

对于并行传输，扫描码会同时发送到计算机的多个引脚上。

计算机接收到扫描码后，会根据预先定义的映射表将其转换为相应的字符或功能。

映射表可以根据键盘类型和语言环境的不同而有所不同。

计算机将转换后的按键信息存储在一个缓冲区中，供操作系统或应用程序读取和处理。

总结来说，键盘扫描原理通过扫描码和数据传输将按键状态传输给计算机。

这种技术广泛应用于各种键盘设备，包括传统的有线键盘和现代的无线键盘。

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 ...
