#REDIRECT [[PS/2 Keyboard]]
 
PS/2键盘是一种使用 [[PS/2 | 串行通信]] 与PS/2控制器对话的设备。 理想情况下，每种不同类型的PS/2控制器驱动程序都应提供某种标准/简单的 “发送字节/接收字节” 接口，PS/2键盘驱动程序将使用此接口，而无需关心较低级别的详细信息 (例如设备插入的PS/2控制器类型)。
 
PS/2键盘接受命令并发送对这些命令的响应，还发送指示何时按下或释放键的扫描代码。 请记住，这些扫描代码 (来自下表) 可以由PS/2控制器更改 (即翻译)，具体取决于控制器的设置。
 
== 命令 ==
 
PS/2键盘接受许多类型的命令。 一个命令是一个字节。 某些命令具有多个数据byte，必须在命令byte之后发送。 键盘通常通过发送 “ACK” (确认命令) 或 “重新发送” (说上一个命令有问题) 来响应命令。 不要忘记在命令，数据和键盘响应之间等待。
 
PS/2键盘接受的命令是:

== 特殊字节 ==
 
键盘向系统发送字节。 其中一些字节具有特殊含义 (例如，来自上述命令的响应)。 键盘可能发送的字节是:
 
{| {{wikitable}}
|-
! 响应字节
! 含义
|-
| 0x00
| 键检测错误或内部缓冲区溢出
|-
| 0xAA
| 自检通过 (在 “0xFF (reset)” 命令或键盘加电后发送)
|-
| 0xEE
| 对 “0xEE (echo)” 命令的响应
|-
| 0xFA
| 命令确认 (ACK)
|-
| 0xFC and 0xFD
| 自检失败 (在 “0xFF (reset)” 命令或键盘加电后发送)
|-
| 0xFE
| 重新发送 (键盘希望控制器重复它发送的最后一个命令)
|-
| 0xFF
| 键检测错误或内部缓冲区溢出
|}
 
键盘发送的所有其他字节都是扫描码，其中解释取决于当前选择的扫描代码集。
 
== 驱动程序模型 ==
 
=== 命令队列和状态机 ===
 
命令必须一次发送一个 (例如，如果你的驱动程序是中断驱动的，则无法在IRQ处理程序中开始发送命令，因为IRQ处理程序之外的代码可能正在发送命令的中间)。 直到你收到确认后，该命令才完成。 例如，如果你发送命令，并且键盘以 “0xFE (重新发送)” 作为响应，那么你必须再次发送命令 (可能在你放弃之前限制为3次重试，并假设键盘不支持你正在发送的命令或出现硬件故障)。最后，有时你想一次发送几个命令。 例如，你可能有一个 “reinitialise()” 函数，该函数设置扫描代码集，设置typematic字节，设置led并启用扫描。
 
实现这一目标的最简单方法是驱动程序维护命令队列。 将命令添加到队列时，如果队列为空，则开始发送命令; 否则，将命令附加到队列。 当你从键盘收到 “0xFA (ACK)” 时，你会丢弃队列头部的命令，并开始发送队列中的下一个命令 (如果有)。 如果你从键盘收到 “0xFE (重新发送)”，则可以在队列的头部重新发送命令。
 
驱动程序的剩余部分应该是一种状态机。 当一些命令成功完成时，以及当从键盘接收到各种字节时，状态机进入不同的状态。 例如，驱动程序可能处于默认状态，并且接收到中断代码，该中断代码将其置于 “接收到中断代码后等待扫描代码” 状态。 然后，它可能会接收多字节扫描代码的第一个字节，并切换到 “在接收中断代码后等待第二个字节扫描代码” 状态。 最后，它可能会接收扫描代码的第二个/最后一个字节，然后切换回默认状态。
 
 
=== 扫码集、扫码和键码 ===
 
扫描代码集是一组代码，用于确定何时按下或重复或释放某个键。 有3组不同的扫描码。 最老的是 “扫码集1”，默认是 “扫码集2”，还有更新的 (更复杂的) “扫码集3”。 ''注意: 通常在PC兼容系统上，键盘本身使用扫描代码集2，并且键盘控制器将其转换为扫描代码集1以实现兼容性。 有关此翻译的更多信息，请参阅 [["8042"_PS/2_Controller#Translation| "8042" _ PS/2 _ 控制器]]。''
 
现代键盘应该支持所有三个扫描代码集，但是有些则不支持。 扫描代码集2 (默认值) 是唯一保证支持的扫描代码集。 从理论上讲 (我还没有尝试过)，应该可以尝试设置扫描代码集1或扫描代码集3，然后询问键盘当前正在使用哪个扫描代码，看看它是否实际上正在使用请求的扫描代码集。 以这种方式，可以确定键盘确实支持哪个扫描代码集。
 
扫描码本身是一个或多个字节的序列。 在某些情况下，序列可以多达6个字节 (例如，扫描代码集1中的暂停/中断键
按下时生成序列0xE1，0x1D，0x45，0xE1，0x9D，0xC5)。 这种情况并不理想。 通常 (用于以后的处理)，你希望将这些 “一个或多个字节序列” 转换为唯一标识特定键的单个整数，可以在诸如查找表之类的事情中有效使用 (无需稀疏使用 “许多GiB” 查找表)。
 
“关键代码” 没有标准 - 这是你必须为操作系统弥补或发明的东西。 我个人喜欢有一个8位键代码的想法，其中最高的3位确定键盘上的哪一行，最低的5位确定哪一列 (本质上，键盘被视为最多8行和最多32列键的网格)。 无论你选择使用什么键代码，它都应该是所有键盘驱动程序 (包括USB键盘) 使用的东西，也可能用于其他输入设备 (例如，鼠标左键可能被视为 “键代码0xF1”)。
 
基本上，当键盘驱动程序的状态机知道它已经收到完整的扫描代码时，下一步就是将 “一个或多个字节” 的扫描代码转换为键代码。
 
=== 键代码、键状态和键映射 ===
 
一旦有了键代码，下一步就是跟踪当前正在按下的键。 想象一个使用 “WASD” 键进行玩家移动的计算机游戏-按下 “a” 键时，玩家会顺时针旋转。 游戏如何知道当前是否正在按下 “a” 键？为此，你需要一个标志数组，其中每个标志对应于一个关键代码。 这里有一个隐藏的奖励-键盘驱动程序本身可以使用相同的 “标志数组” 来确定shift键，控制键，alt键等是否关闭，这在尝试将键代码转换为实际的ASCII字符或Unicode代码点时非常有用。 例如，如果用户按下 “a” 键，则它可能对应于 “a” 或 “a” (取决于capslock状态以及当时是否按住shift键)，或者可能根本不对应于有效字符 (例如 “control-a” 或 “alt-a” “)。
 
还要注意 (例如) “WASD” 游戏不在乎键是否为 'W'，'A'，'S' 和 'D'。 游戏希望了解键盘左侧特定 “t形” 图案的按键。 如果键盘恰好是不同的东西，那么在同一位置的键可能是完全不同的 (例如，它们将是德沃夏克键盘上的 '<' 、 'a' 、 'o' 和 'e' 键)。 这有助于解释我的偏好有一个8位键代码，其中最高的3位决定键盘上的哪一行，最低的5位决定哪一列 (这很容易让游戏询问第三行左边的第三个键的状态)。
 
一旦能够跟踪当前正在按下的键，下一步就是 (尝试) 将键转换为ASCII字符或Unicode代码点。 在这一点上，你需要知道用户拥有哪种类型的键盘-是 “US QWERTY” 还是 “French AZERTY”，某种形式的Dvorak，还是阿拉伯语。 要处理许多不同的键盘布局，键盘驱动程序需要使用表格将键代码转换为ASCII字符或Unicode代码点; 因此，你只需要加载不同的 “键映射” 表即可支持不同的键盘布局。
 
然而，事情并不是那么简单。 不同的键盘布局可以有不同的元键、不同的状态发光二极管等。 键映射表也必须对这些差异进行排序。 这就是为什么你不想检测键盘发光二极管是否更早发生了变化，而是希望在你在键映射表中找到键代码的条目后发送 “设置发光二极管” 命令 (如有必要)。
 
处理的最后一步是将所有相关信息组合成某种 “keypress数据包” 结构，并将其发送给任何人 (例如GUI)。 整个 “keypress数据包” 可能包括以下内容:
* Unicode码点 (如适用)
* 关键代码
* 按下/释放标志
* 各种其他关键状态 (移位、alt、控制等)
* 各种 “切换” 状态 (CapsLock、ScrollLock、NumberLock等)
 
== 扫描代码集 ==
 
由于有3个不同的扫描代码集，因此有3个不同的表 (每个扫描代码集一个)。 一些扫描代码对应于随着时间的推移而添加的额外键，并且变得 “相对标准”。 为了帮助保持跟踪，扫描代码已在下表中进行了分类和标记。 使用的标签是:
 
{| {{wikitable}}
|-
! 标签
! 含义
|-
| (keypad)
| 数字键盘上的键 (通常在键盘的右侧找到)。
|-
| (ACPI)
| 是 “ACPI” 键组的一部分的键 (通常在键盘顶部附近找到)。 许多现代键盘实际上没有这些键 (如果我没记错的话，它们在20世纪90年代末很流行，但此后变得不那么普遍了)。
注意: 不要让这个名字愚弄你-这些键与ACPI完全无关，并且表现得像任何其他普通键 (但对于支持电源管理的操作系统可能有用)。
|-
| (多媒体)
| 是多媒体键组的一部分的键 (通常在键盘顶部附近找到)。 许多现代键盘确实至少有一些这样的键。 这些键中的一些用于媒体播放器 (音量控制、播放/暂停、下一首曲目、上一首曲目等)，一些用于网络浏览 (上一个网页、下一个网页、刷新、收藏夹/书签等)，和一些用于启动应用程序 (例如，启动电子邮件客户端，启动计算器，打开 “我的电脑” 等)。
