查看“PS/2 Keyboard”的源代码

== 概述 ==

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Scan Code。（译者注：键盘硬件一般使用矩阵电路扫描的方式来识别当前按下的键位，具体请查阅其它资料） 请记住，这些Scan Code(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 “Resend” (说明上一个命令有问题) 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Scan Code，其中解释取决于当前选择的Scan Code Set。

== 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，并可以认为键盘不支持你正在发送的命令或出现硬件故障)。 最后，假如有时您想一次发送几个命令。 你可能有一个 “reinitialise()” 函数，该函数设置Scan Code Set，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一个命令队列。 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 (如果有的话)。 如果你从键盘收到 “0xFE (Resend)”，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，驱动程序可能开始处于默认状态，然后接收到中断代码，此时该中断代码将其置于 “接收到中断代码后等待Scan Code” 状态。 然后，它可能会接收多字节Scan Code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Scan Code” 状态。 最后，它可能会接收Scan Code的第二个/最后一个字节，然后切换回默认状态。


=== Scan Code Sets, Scan Codes 和 Key Codes ===

Scan Code Set是一组编码，用于确定何时按下或重复或释放某个键。 有3组不同的Scan Code Set。 最老的是 “scan code set 1”，默认是 “scan code set 2”，还有更新的 (更复杂的) “scan code set 3”。 ''注意: 通常在PC兼容系统上，键盘本身使用Scan Code Set 2，并且键盘控制器将其转换为Scan Code Set 1以实现兼容性。 有关此处转换的更多信息，请参阅 [["8042"_PS/2_Controller#Translation|"8042"_PS/2_Controller]]。''

现代键盘应该支持所有三个Scan Code Set，但是仍有些则不支持。 Scan Code Set 2 (默认值) 是唯一保证支持的Scan Code Set。 从理论上讲 (我还没有尝试过)，应该可以尝试设置Scan Code Set 1或Scan Code Set 3，然后询问键盘当前正在使用哪个Scan Code，看看它是否实际上正在使用请求的Scan Code Set。 以这种方式，可以确定键盘确实支持哪个Scan Code Set。

Scan Code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，Scan Code Set 1中的Pause/Break键
按下时生成序列0xE1，0x1D，0x45，0xE1，0x9D，0xC5)。 这种情况对后续开发并不理想。 通常，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 (这种表不需要是那种稀疏的又有几个G的查找表)。

所以提出了Key Code，“Key Code” 没有标准 - 这是你必须为操作系统弥补或发明的东西。 我个人喜欢一个有8位Key Code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Key Code，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 “Key Code 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Scan Code时，下一步就是将 “一个或多个字节” 的Scan Code转换为Key Code。

=== Key Code、按键状态和键映射 ===

一旦有了Key Code，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，玩家会逆时针旋转。 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Key Code。 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键等是否按下，这在尝试将Key Code转换为实际的ASCII字符或Unicode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'。 游戏只希望掌握键盘 “T形” 区域的按键。 如果有键盘恰好这些键不是T形布局的，那么在同一位置的键可能是完全不同的 (例如，它们将是Dvorak键盘上的 '<' 、 'A' 、 'O' 和 'E' 键)。 这也解释了我的偏好8位键代码方案的原因，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Key Code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（meta keys）、不同的状态LED等。 键映射表也必须对这些差异进行处理。 这就是为什么如有必要的情况下，你不应该检测键盘LED是否已发生了变化，而应该在你在键映射表中找到Key Code的条目后发送 “设置LED” 命令。

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)
* Key Code
* 按下/释放标志
* 各种其他关键状态 (shift、alt、control等)
* 各种 “切换” 状态 (CapsLock、ScrollLock、NumberLock等)

== Scan Code Set ==

由于有3个不同的Scan Code Set，因此有3个不同的表 (每个Scan Code Set一个)。 一些Scan Code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，Scan Code已在下表中进行了分类和标记。 首先使用的分类标签如下:

{| {{wikitable}}
|-
! 标签
! 含义
|-
| (keypad)
| 数字键盘上的键 (通常在键盘的右侧找到)。
|-
| (ACPI)
| 属于 “ACPI” 键组部分的键 (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（译者注：BIOS有Advanced Configuration and Power Interface-高级配置与电源接口）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)。
|-
| (multimedia)
| 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(上一网页、下一网页、刷新、收藏夹/书签等)， 还有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）。
