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
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。
WINTEC-KB66U可编程键盘用户手册
KB66U可编程键盘用户手册一.程序安装⒈先运行setup.exe程序，然后出现以下对话框。
按“Next”键继续⒉同意协议与否选择对话框，“Yes”键继续。
⒊用户信息确认对话框，按“Next”键继续⒋安装路径对话框，选择目标文件夹，然后按“Next”键继续。
⒌拷贝文件对话框，按“Next”键继续。
⒍提示重启计算机对话框，按”Finish”重启后设置生效。
二.键盘的编程软件1.选择键盘当运行程序时会出现以下对话框：选择所想编程的产品类型，然后按“确定”键确定。
2. 编辑键码拖动鼠标，使鼠标指在键盘的某一个按钮上，当按钮颜色变成灰黑色时就可以对此按钮编程了。
在可编程的按键上点击鼠标左键，会弹出一个滑行菜单。
这时可以用“Key Code”的方式给按键赋值，或者“ASCII CODE”的方式给按键赋值。
，你还可以点击滑行菜单条中“Clear”来清除已赋的码值，给一个按键赋值后，点击“Layer Index”来指定这个按键的键层。
Ⅰ.Key code在这种方式下，你能用任意扫描码给一个按键赋值在以上对话框的“键盘”画面上显示了最常用的键码，并在“Special Codes”区域列出了一些特殊码。
从“键盘”画面上选择一个键或双击“Special Codes”区域的某一项，则将其键码添加到“Mapping Sequence”目录中。
通过以上操作可以把8个码写入某一个键里面。
在这个画面上并不是任何键码（扫描码）都是可选的，但可以在“0x”下的方格内输入一个十六进制码，然后按“Insert”确定。
例如：如果在“键盘”区域按“Shift”、“H”、“E”、“Shift”、“L”、“L”以及“O”键，在上面对话框中的“Mapping Sequence”目录中就会显示这些键值。
如果在上面的“Mapping Sequence”目录中删除“O”项，你可以用鼠标右键单击“O”项，将弹出一个包含2 个选项的滑行菜单。
选择其中的“Delete”选项就可以删除“O”项内容；如果选择“Clear All”选项，就会把该目录中的所有内容删除。
键盘按键对应的编码
键盘按键对应的编码
键盘按键对应的编码通常是通过使用ASCII码（American Standard Code for Information Interchange）或Unicode编码来表示的。
这些编码用于将键盘上的每个按键映射到特定的字符或控制码。
下面是一些常见的键盘按键和它们对应的ASCII码或Unicode编码：
1. 字母键：A-Z对应的ASCII码为65-90（大写字母）和97-122（小写字母）。
2. 数字键：0-9对应的ASCII码为48-57。
3. 功能键：F1-F12对应的ASCII码为112-123。
4. 控制键：例如Enter键对应的ASCII码为13，Tab键对应的ASCII码为9，空格键对应的ASCII码为32，退格键对应的ASCII码为8。
5. 特殊符号键：例如感叹号键对应的ASCII码为33，问号键对应的ASCII 码为63，加号键对应的ASCII码为43，等等。
Unicode编码是一种更为全面的字符编码系统，它包含了全球范围内的各种字符和符号。
Unicode编码使用16位或32位来表示每个字符，包括了各种语言的字母、标点符号、数学符号、货币符号等等。
需要注意的是，不同的操作系统和键盘布局可能会有一些细微的差异，因此具体的键盘按键编码可能会有所不同。
如果需要获取特定键盘按键的编码，最好
参考相关的文档或编程语言的API文档。
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。
python keyboard库用法 -回复
python keyboard库用法-回复Keyboard库是一个在Python中实现按键监控和模拟按键操作的第三方库。
它提供了一系列函数和方法，使得我们可以轻松地实现键盘事件的监听和模拟，从而可以在编程中自动化处理键盘输入。
本文将详细介绍Keyboard库的用法，包括安装与导入、键盘事件监听、模拟按键操作等主要内容。
1. 安装和导入Keyboard库：要使用Keyboard库，首先需要安装它。
可以通过在命令行窗口中运行以下命令进行安装：pip install keyboard安装完成后，在Python脚本中导入Keyboard库：pythonimport keyboard2. 监听键盘事件：Keyboard库提供了丰富的函数和方法，可以用于监听键盘事件。
下面是一些常用的键盘事件监听函数：- `keyboard.is_pressed(key)`- 功能：判断某个键是否被按下- 参数：key - 键的名称或键码- 返回值：True - 如果键被按下；False - 如果键未被按下- 示例：pythonif keyboard.is_pressed('a'):print('键a 被按下')- `keyboard.wait(key=None)`- 功能：阻塞程序直到某个键被按下- 参数：key - 键的名称或键码（可选）- 返回值：None- 示例：pythonkeyboard.wait('enter') # 阻塞程序直到回车键被按下- `keyboard.add_hotkey(hotkey, callback, suppress=False)`- 功能：注册快捷键- 参数：hotkey - 快捷键的名称或键码；callback - 当快捷键被按下时要执行的回调函数；suppress - 是否要阻止快捷键的默认行为（可选，默认为False）- 返回值：None- 示例：pythondef callback():print('快捷键被按下')keyboard.add_hotkey('ctrl+alt+a', callback)3. 模拟按键操作：除了监听键盘事件，Keyboard库还提供了模拟按键操作的函数，可以用于在编程中自动化触发键盘输入。
python keyboard库用法
python keyboard库用法Python的keyboard库是一个用于监控和控制键盘事件的库。
它可以用于模拟键盘输入、监听按键事件以及进行特定的键盘操作。
本文将介绍keyboard库的使用方法，并给出一些示例代码和应用场景。
keyboard库的安装非常简单，只需要使用pip命令即可完成安装。
在命令行中输入以下命令即可安装keyboard库：```pip install keyboard```安装完成后，就可以在Python代码中引入keyboard库并开始使用了。
首先，我们可以使用keyboard模块的`add_hotkey`方法来注册热键。
热键是一种快捷键的扩展，当按下指定的组合键时，可以执行特定的操作。
下面是一个使用`add_hotkey`方法注册热键的示例代码：```pythonimport keyboarddef on_hotkey():print("Hotkey pressed!")keyboard.add_hotkey('ctrl+shift+a', on_hotkey)keyboard.wait('esc')```在上面的代码中，我们定义了一个名为`on_hotkey`的函数，当热键被按下时，该函数会被调用并打印出一条消息。
然后，我们使用`add_hotkey`方法注册了一个热键，当同时按下`ctrl+shift+a`组合键时，会触发这个热键。
最后，我们使用`wait`方法来等待`esc`键的按下，以保持程序运行。
除了热键注册，keyboard库还可以用于监听按键事件。
我们可以使用`keyboard.on_press`和`keyboard.on_release`方法来注册按键按下和抬起的事件处理函数。
下面是一个监听按键事件的示例代码：```pythonimport keyboarddef on_press(event):print(f'Key {} pressed')def on_release(event):print(f'Key {} released')keyboard.on_press(on_press)keyboard.on_release(on_release)keyboard.wait('esc')```在上面的代码中，我们定义了两个函数`on_press`和`on_release`，分别用于处理按键按下和抬起的事件。

This document details the alternative make and break PS/2 scan code and USB code response for the Windows Logo key, Application Keys, and Advanced Configuration & Power Interface (ACPI) power controls./This document supercedes all versions of the New Keys Specifications for the Windows Keys and Windows Hardware Quality Labs WHQL Keyboard Specification. There is no change required for developers of Windows-based applications to support any compatible implementation.The requirements for compatibility testing are not changed, and a keyboard vendor can implement these new keys successfully following the 1.0, 1.1, or 1.2 versions of the New Keys Specification. There is no change required for developers of Windows-based applications to support any compatible implementation.Revision HistoryWindows Keys Support for Windows Software ApplicationsThe three Windows K eys report the following key codes in the Microsoft Windows 95, Windows 98, and Windows NT® operating systems, and future versions of Windows operating systems.Key Codes for Scan Code Set 1:Key Codes for Scan Code Set 2:Key Codes for USB Usage Tables:What Software Applications Vendors Should Support and How To provide support for the Windows Keys, an application should support the application key virtual key scan code (5D) as a context menu event similar to a right mouse button click in some applications today.Applications vendors are encouraged to extend their support beyond the application key to include support for application key combinations like CTRL+Application, A LT+Application andSHIFT+Application. These key combinations are reserved for applications to support. Support for Windows+Application is reserved for the operating system.Suggestions for Support of Application Key Combinations Context menu at the location of the text cursor (instead of the mouse pointer)Launch automated help agentPop up list of last 5 actions (or list of commonly accessed functions)Enable/Disable macro recording or other user controllable featuresSwitch to next open window in a multiple documentUser assignable key through an application UIApplication Key Support in the Microsoft Windows Operating Systems The application key will primarily function to bring up a context menu at the selection or mouse pointer. This functionality is the same as the right mouse button click in some applications today.Application Key Response Supported by the Operating System Operating SystemWindows 3.x no response1Windows NT 3.5x no response1Windows NT 4.0 context menu on selectionWindows NT 4.0 context menu on selectionWindows 95 context menu on selectionWindows 98 context menu on selectionWindows still reports a 5D virtual key code which means that applications can enable functionalityUsing the Windows Logo Key Logo and Application Key Logo in DocumentationThe Windows Logo key and the Application Logo key may be used by OEMs, ISVs and IHVs in documentation that describes the functionality of the Logo keys, provided such description is consistent with Microsoft’s guidelines for use of the Logo keys.•It is not necessary to obtain a Logo license from Microsoft in order to refer to the Logo keys in documentation. This is the only permissible non-licensed use of the Windows Logo.•The Logos may not be used in any way other than as specified in the Logo license guidelines. •Upon request, Microsoft will provide camera-ready artwork of the Logos to be used in documentation. Send your e-mail request to Microsoft Windows Hardware Quality Labs at**********************with “Artwork Request” in your subject line. Alternativel y, you may use the Windows flag symbol provided in the “Wingdings®” font. This character is available by pressing ALT + 0255 on the numeric keypad.•You may not alter the Logos in any way.•The Logos should be typed with an empty space before and after each symbol, followed by a plus sign and another space, followed by the modifier if appropriate. Examples are shown:Windows Logo key + B or + BApplication key + S or + + SWindows Logo Key Support (Reserved for Operating System Use)The Windows Logo keys are reserved for system level functions. Software developers should not implement support for the Windows Logo keys in Windows 95, Windows 98, or Windows NT-based applications. The Windows Logo keys are supported in the operating system and provide system level functionality to the end user. The following table lists a few of the Windows Logo key combinations and their functionality. This list is not exhaustive and additional combinations will be used by the Microsoft Windows 95, Windows 98, or Windows NT operating systems.Windows Keys Support for OEMs and Keyboard IHVs OEMs that buy their keyboards with Windows Logo keys from a licensed keyboard manufacturer and do not modify the keyboard product except to add their Logo and other cosmetic changes are not required to license the Windows Logo keys from Microsoft. If the OEM product changes the layout or BIOS of an already licensed keyboard the OEM must go through the same licensing and certification procedure as described in the next section of this document.Software Support of the Windows Keys in the Windows 95/98 Operating SystemThe Windows Keys are supported in the Windows 95, Windows 98, or Windows NT operating systems user interface. Application vendors will enable functionality for the Application key in their applications. 10 Windows Logo key combinations are reserved for OEM use.Special Keys Reserved for OEM UsageTen (10) Windows Logo keys combinations have been reserved for OEM use. These keys can be used by OEMs to provide keyboard hotkey controls for Speaker Volume, Monitor/LCD Brightness or Contrast, Password, or other value added functions.Multiple Key Operation RequirementsValid 2-Key CombinationsThe following list combined with the “Valid Final Keys” table, defines th e valid 2-key combinations. When any one of the keys below is pressed, followed by a 2nd key from the “Valid Final Keys” table, the keyboard must properly indicate that those 2 keys are pressed. There are no exceptions to these 2-Key Combinations.•LWIN•RWIN•LCTRL•RCTRL•LSHIFT•RSHIFT•LALT•RALTValid Final KeysThe following table lists the final keys that are required to work for valid two and three key combinations. Any key from the Valid 2-Key Combinations list combined with any key from the table below must work properly. Any 2 keys indicated in a row from the Valid 3-Key Combinations table combined with any key from the table below must work properly. Exceptions to this requirement are listed in Combinations of 3-Keys which are unavailable. Invalid key combinations will generate a Key Error code.Indicates Traditional IBM Final keys.Valid 3-Key CombinationsThe following table combined with the “Valid Final Keys” table, defines the valid 3-key combinations. For each row in the table below, an “X” indicates that key is selected. When the two keys in a row are pressed followed by a 3rd key from the “Valid Final Keys” table, the keyboard must properly indicate that those 3 keys are pressed. Exceptions to these tables are listed below. Any 3-key combinations not listed are not required to work, but ma y do so at the keyboard manufacturer’s discretion.Indicates Traditional IBM 3-Key combinations.Combinations of 3-Keys which are UnavailableBased upon the s tandard industry accepted 16 X 8 scanning matrix, several keys will be “ghosted”, meaning not uniquely detectable by the firmware during the key switch scanning of 3-Key combinations. To accommodate this, the following table details the key combinations, which are excluded from the above tables. These 3-key combinations are not required to work, but may do so at the keyboard manufacturer’s discretion.Additional General RequirementsLWIN and RWIN Keys as modifiersThis keyboard must generate unique scan codes for make and break. The LWIN and RWIN keys must be treated as modifier keys, much in the same way as ALT, and Control keys are handled today. It will be up to the operating system to decide on an implementation scheme for the modifier key functionality.Building a Keyboard with the Windows KeysTools Needed to Build a Keyboard with the Windows Keys •Keyboard Scan Code Specification (this document).•Microsoft Windows Logo License Agreement•Windows Logo Key License Agreement.•Windows Exhibit A from the Device Testing Agreement.•Windows Exhibit B from the “Designed for Microsoft” Logo License Agreement.•Windows Keyboard Test Kit: Test Procedures and Test Tools.How to Get the WHQL Keyboard Test Kit and Keys SpecificationThe latest version of the Keyboard Scan Code Specification is available at/hwdev/desinit/scancode.htm.The latest version of the WHQL Keyboard Test Kit is available electronically directly from the Windows Hardware Quality Labs Web Site at /hwtest/testkits/.

Compatibility Requirement1. Keyboards are required to be compatible at the Windows virtual key code level. You can accomplish this by either:a) Developing a keyboard with the electronics and firmware that comply with thespecification or by,b) Developing a software driver for use with Windows 3.1 and Windows 95 that maps theproper virtual key codes to keyboard events on your keyboard.2. Test your implementation using the WHQL Keyboard Test Procedures to ensure that single-key,two-key and three-key combinations work correctly, including the Windows Logo keys (ifimplemented) and report the proper virtual scan codes in Windows.3. Once you are satisfied that your keyboard passes the tests, run the full Test Suite and use it togenerate log files of encoded test results that must be included with the other information required for your Test Submission. Full testing instructions are provided in the WHQL Keyboard TestProcedures.Retest RequirementsAny time that you implement the Windows Keys on a new keyboard technology, you must go through this testing and certification procedure. You will also need to submit a retest any time that you change the key layout or the BIOS firmware on a certified keyboard.Recommended Physical Locations of the Windows KeysFor full travel desktop keyboards Microsoft recommends that the Windows Logo keys be located near the current modifier keys like CTRL, SHIFT and ALT since the Windows Logo keys must also function as modifier keys. The Application key can be located wherever it appropriately fits. In the attached diagram the keys were placed on the bottom row on either side of the space bar. By changing the current size of the space bar the Windows Keys can be located in a similar position on a standard keyboard.Recommendations for Laptop KeyboardsGiven the crowded nature of laptop keyboards it is difficult to add three Windows Keys. A minimal implementation of the Windows Keys would require the addition of one Windows Logo Key and the replacement of the [Fn] key for the Application key.The two Windows Logo Keys are not distinguished individually by the Microsoft Windows 95 operating system and the IntelliType software only uses a Left Windows Logo key + Right Windows Logo key press for the Logon/Logoff function.Design Requirements:•The Windows Logo Key needs to function as a modifier key (CTRL, SHIFT and ALT).•There can be no other icons or words associated with the Windows Flag trademark on the keycap. Design Options:•There do not need to be Left and Right Windows Logo keys to get full functionality in Windows 95. •The Application key can be a dual function key and can be used to replace the Fn. key.ACPI Power Management KeysThe three ACPI Power Management keys report the following key codes in the Microsoft Windows 95, Windows 98, and Windows NT and operating systems.Key Codes for Scan Code Set 1:ACPI key Make Break Windows Virtual KeyPower Event E0 5E E0 DE N/ASleep Event E0 5F E0 DF N/AWake Event E0 63E0 E3N/AKey Codes For Scan Code Set 2:ACPI key Make Break Windows Virtual KeyPower Event E0 37 E0 F0 37 N/ASleep Event E0 3F E0 F0 3F N/AKey Codes for USB Usage Tables:Usage Page and Usages for Audio ControlA device wanting to be to recognized as a HID audio control device must declare itself as being a Consumer Control device (usage 0x01), as defined in the Consumer Page (page 0x0C) in the Universal Serial Bus HID Usage Tables Version 1.0 specification. This means that its top-level application collection should be Usage Page (Consumer), Usage (Consumer Control). When such a device is enumerated by the operating system, the supporting software (HIDSERVE.EXE) is installed and loaded on the host system. Table 1 outlines the Consumer Page audio controls that are supported in Windows 2000.Table 1. Consumer Page audio controls supported in Windows 2000.Usage Usage Name Usage Type0xE0 Volume* Linear Control (LC)0xE2 Mute* On/Off Control (OOC)0xE3 Bass Linear Control (LC)0xE4 Treble Linear Control (LC)0xE5 Bass Boost* On/Off Control (OOC)0xE7 Loudness On/Off Control (OOC)0xE9 Volume Increment* Re-trigger Control (RTC)0xEA Volume Decrement* Re-trigger Control (RTC)0x152 Bass Increment Re-trigger Control (RTC)0x153 Bass Decrement Re-trigger Control (RTC)0x154 Treble Increment Re-trigger Control (RTC)0x155 Treble Decrement Re-trigger Control (RTC)*) These controls are supported in Windows 98 (original release and Service Pack 1 release).The Volume, Bass, and Treble usages (of type LC) should be deployed for controls that generate both increment and decrement data represented by a 2-bit value, whereas the associated Increment and Decrement usages (of type RTC) should be deployed for pairs of one-bit controls (traditional button controls). The hardware design and implementation determines what usage types are appropriate for the HID firmware implementation for a particular device.It's also important to notice that any re-triggering of events should be done by software timers in the host system, and not by hardware timers in the device itself. For example, if the user keeps pressing the Volume Increment button, the device should only generate one input report with this state information. Host software will perform the actual re-triggering of events that will lead to continuous increments of the volume until the device generates another input report indicating that the button has been released or until the maximum volume has been reached.Important Design AspectsThe supported HID audio controls:•Affect audio playback only. There's no support for HID-based controls that affect audio recording, etc.•Affect audio playback by the default system audio device (same device as sndvol32.exe controls). •Should be declared right beneath the top-level application collection in the HID firmware in order to be discovered and utilized by the host system. Important: do not wrap these controls in sub-collections.Sample Firmware DesignsThe following two samples illustrate how firmware that uses the audio controls listed above can be implemented. The first sample uses the Volume usage (of type LC) for the volume control, and the second sample uses the Volume Increment and Volume Decrement usages (of type RTC). Notice that the mute button in both of these samples is implemented as a Relative, Preferred State type of control, or a toggle, which means that 0-to-1 transitions will toggle mute on/off.Sample 1.Usage Page (Consumer)Usage (Consumer Control)Collection (Application)Usage (Volume)Logical Minimum (-1)Logical Maximum (1)Report Size (2)Report Count (1)Input (Data, Variable, Relative, Preferred)Usage (Mute)Logical Minimum (0)Logical Maximum (1)Report Size (1)Report Count (1)Input (Data, Variable, Relative, Preferred)Report Count (5)Input (Constant)End CollectionSample 2.Usage Page (Consumer)Usage (Consumer Control)Collection (Application)Logical Minimum (0)Logical Maximum (1)Usage (Volume Increment)Usage (Volume Decrement)Report Size (1)Report Count (2)Input (Data, Variable, Absolute, Preferred)Usage (Mute)Report Count (1)Input (Data, Variable, Relative, Preferred)Report Count (5)Input (Constant)End CollectionAppendix A: Windows Standard PS/2 Scan Codes General RequirementsThis keyboard must be downward compatible with an enhanced type 101 keyboard. This keyboard must be fully compatible with the PS/2 Keyboard Controller command set. It must support Scan Set 2. Three additional scan codes are to be generated from the three Windows Keys (Left Windows, Right Windows, and Application).The virtual key codes described in the following tables are specifically for Windows operation only and are not generated by the keyboard directly. The keyboard manufacturer will need to provide a Windows Logo keyboard driver to support the three virtual keys for use with the Windows v. 3.1 operating system (not required for Logo purposes). The support will be built into drivers shipped with future versions of the Windows and Windows NT operating systems.Typematic CharacteristicsTypematic is the term used for keys that will automatically repeat after a specified time delay. In scan code 1 and scan code 2, key 126 is the only key that is not Typematic. (This key is the only one that does not send a break code as well).Scan Code Assignments:Under all Microsoft operating systems, all keyboards actually transmit Scan Code Set 2 values down the wire from the keyboard to the keyboard port. These values are translated to Scan Code Set 1 by the i8042 port chip.1 The rest of the operating system, and all applications that handle scan codes expect the values to be from Scan Code Set 1. Scan Code Set 3 is not used or required for operation of Microsoft operating systems.The following recommendations are made for those who wish to define a new scan code for a proprietary purpose. It is the manufacturer’s responsibility to implement a software driver that supports any such scan codes. New scan codes must not be chosen from those currently recognized by the operating system. Keys that are called out with a Key Number or Key Name in the Scan Code Table are currently recognized by and used by the operating system.Single-Byte Scan CodesThe values discussed below are all Scan Code Set 1 values.Avoid Set 1 scan codes above 0x79, since the release (key up) code would be 0xFA or greater, and the keyboard driver is known to interpret such values as responses from the 8042 chip, not as keystrokes (scan codes). Specifically, 0x7A, 0x7E and 0x7F are problematic for the Windows NT keyboard driver in 3.51 and 4.0 since 0xFE is RESEND, 0xFA. is ACKNOWLEDGE and 0xFF seems to be simply just swallowed up. The effect is that key releases would be lost, and error logs fill up.1 This mode is set by issuing a 0xF0 command byte to the keyboard, and turning the translate bit(0x40) in the 8042 command byte on. On Intel and Power PC machines, it is the firmware that initializes the keyboard and 8042 chip this way, while Windows NT® explicitly sets this mode for MIPS and Alpha.In the very early days of Windows NT®, an attempt was made to use the much more orthogonal Scan Code Set 3, but due to bugs in the implementation of this Scan Code Set on numerous OEM keyboards, the idea was abandoned.•Avoid 0x60 and 0x61, since the release (up key) code would be 0xE0 and 0xE1, which are reserved prefix bytes.•Avoid 0x00, since that is likely to have some special meaning to code from driver level through to application level.Prefixed Scan CodesSome keys on standard 101/102-key keyboards (and the Microsoft Natural keyboard amongst others) emit a sequence of two bytes, where the 1st byte is either 0xE0 or 0xE1. This method is used primarily to distinguish between left and right versions of the same key, e.g., Left Alt is 0x38 while Right Alt is0xE0 0x38. The 0xE0 prefix is indicated as th e “extended bit” (bit 24) in the lParam of messages such as WM_KEYDOWN. The 0xE1 prefix is much rarer, but operates similarly to the 0xE0 prefix. It’s presence or absence is not indicated through the API in any way.If you use scan codes from the 0xE0 set, make sure the second byte is suitable in the same way as single byte scan code values. In other words:Not greater than 0x79Not 0x60 or 0x61Not 0x00Scan Code TableThe following table lists the full set of Scan Codes as presently recognized by the Microsoft operating systems. The US Key assignments are for reference to a type 101/102 Enhanced keyboard as supported by the Type 4 Keyboard layout. If there is no entry in the 101/102 Enhanced keyboard column, this scan code is currently not recognized by the operating system. The Key Location field has been added to aid in the placement of keys as illustrated in theRecommended Physical Locations of the Windows Keys on page 10.Note * Key 29 is available on the US and not on the International Keyboard.Note ** Keys 42 and 45 are available on the International Keyboard and not on the US Keyboard.Note *** Keys 56 and 107 are used on Brazilian and some Far East keyboards. They not available on US Keyboards.Note ‡Keys are used for Far East keyboards.Note 1 for Scan Code 1:These keys may have additional “shift” and/or “unshift” scan codes preceding the Base Make code and following the Base Break code, depending upon the current state of Num Lock and the state of Shift key/s (when multiple keys are held down at the same time).These Keys are Typematic:。
