[0063] 键盘附件可以向PCD发送Unregi sterDescr iptor (解除注册描述符)命令。 [0063] Keyboard Unregi sterDescr iptor accessory can send to the PCD (deregistration Descriptor) commands. UnregisterDescriptor命令向PCD通知该键盘附件将不再向PCD发送任何与键盘有关的HID事件。 UnregisterDescriptor command informs the keyboard accessory to the PCD will not send any HID keyboard events related to PCD. UnregisterDescriptor命令可以包括下述描述符的唯一标识作为其有效载荷, 该描述符与所要解除注册的附件相关联。 UnregisterDescriptor command may include the following unique identifier descriptor as its payload, the descriptor associated with the attachment to be released registered. 例如,在PCD从键盘附件断开之前,或者作为这种断开处理的一部分,键盘附件可以发送UnregisterDescriptor命令。 For example, the PCD is disconnected from the keyboard accessory before, or as part of such disconnection process, UnregisterDescriptor keyboard accessory can send a command.

[0064] 键盘附件可以向PCD发送AccR印ort (附件报告)命令。 [0064] keyboard accessory can send print AccR ort (annex) command to the PCD. Acdteport命令可以包括报告类型以及与对该键盘附件所执行的一个或多个按键下压动作有关的一个或多个HID 事件。 Acdteport command may include a report type and a related operation in the pressure of one or more keys or keyboard accessory performed more HID event. 在一种示例中,AccR印ort命令可以以定期间隔(例如每8毫秒地)发送给P⑶。 In one example, AccR India ort command (for example, every 8 milliseconds to) to P⑶ at regular intervals. 在一些实施例中,如果在上次传输与下一次传输之间(例如在上次传输之后8毫秒以内)发生多个HID事件,则这多个HID事件可以被聚集(aggregate)并且每8毫秒地作为一个分组而发送到P⑶。 In some embodiments, if between the previous transmission and the next transmission HID plurality of events (e.g., after the last transmission within 8 ms) occurs, then this plurality of events may be aggregated HID (Aggregate) and every 8 ms as a packet transmitted to P⑶.

[0065] P⑶可以向键盘附件发送P⑶Iteport (P⑶报告)命令。 [0065] P⑶ may transmit P⑶Iteport (P⑶ report) command to the keyboard accessory. P⑶Iteport命令可以包括报告的类型以及报告数据,所述报告数据可以包括键盘附件执行动作所用的指令。 P⑶Iteport command may include the type of reporting and the reporting of data, the report data may include instructions to perform an action keyboard accessory used. 在一些实施例中,PCDReport命令可以包括根据当前的PCD状态来设定键盘附件状态的HID报告信息,例如更新指示器408(例如大写锁定、数字锁定、PCD电源/充电、键盘背光等)。 In some embodiments, PCDReport setting command may include a keyboard according to the current state of attachment of the PCD HID report status information, such as the update indicator 408 (e.g., caps lock, number lock, PCD power / charge, keypad backlight, etc.). 例如, 响应于由P⑶从键盘接收到大写锁定按键下压事件,P⑶Iteport命令可以包括使键盘附件上的大写锁定指示器点亮的指令。 For example, in response to receiving from the keyboard by the P⑶ to the Caps Lock key press event, P⑶Iteport uppercase command comprises instructions on the keyboard accessory lock indicator is lighted. 在一些实施例中,P⑶R印ort命令还可以用来向键盘附件传送出错消息。 In some embodiments, P⑶R India ort command can also be used to transmit an error message keyboard accessory.

[0066] 在一些实施例中,键盘附件可以在与P⑶连接时向P⑶发送按键下压事件命令。 [0066] In some embodiments, the keyboard accessory can send a command to the pressure of key press events in connection with P⑶ P⑶. 当键盘附件被连接到P⑶时,键盘附件可以向P⑶发送RegisterDescriptor命令。 When the accessory is connected to the keyboard P⑶, keyboard accessory may send a command to the RegisterDescriptor P⑶. 如上所述,该RegisterDescriptor命令向P⑶通知所连接的附件是键盘、并且该P⑶应当从附件接收与键盘有关的HID事件。 As described above, the attachment RegisterDescriptor P⑶ notification command to connect a keyboard, and the HID event P⑶ should receive from the keyboard related accessories. 例如,当用户压下键区上的按键(例如“A”按键)时,键盘产生与该按键下压有关的HID事件,并使用P⑶附件协议向P⑶发送该HID事件。 For example, when the key (e.g., "A" key) on the user depresses a keypad, a keyboard event with the HID to generate the key-related pressure, and transmits the event to the HID P⑶ use P⑶ accessory protocol. 一旦P⑶ 接收到该PCD附件协议命令,就可以对该命令进行解析以判定键区上的“A”按键受到下压, 随后P⑶可以在P⑶的显示器上显示字符“A”。 Upon receipt of the PCD P⑶ accessory protocol commands can parse the command to determine whether the "A" button on the keypad being pressed down, then P⑶ display characters "A" on the display P⑶. 在一些实施例中,P⑶可以根据从键盘附件接收的输入,来对键盘附件上的各种指示器灯进行控制,以表明是否接收了正确的按键下压事件。 In some embodiments, P⑶ possible to control various indicator lights on the keyboard accessory attachment received from the keyboard input is received to indicate whether the correct key press event. 例如,由于大写锁定按键不会造成屏幕上显示字符,所以用户可能不能知道PCD是否接收了与大写锁定按键相关联的HID事件。 For example, because the Caps Lock key does not cause display of characters on the screen, so the user may not know whether to receive a PCD key associated with the HID Caps Lock event. 在这样的情形下,在接收到大写锁定事件之后,PCD可以向键盘发送命令以点亮与大写锁定按键相关联的指示器,从而提供PCD正确地接收了该事件的视觉指示。 In such a case, after receiving the caps lock event, PCD may send a command to the keyboard to light up the indicator associated with the key caps lock, thereby providing a PCD correctly received the visual indication of the event. 在一些实施例中,PCD可以根据键盘附件周围环境中的环境光来对键盘附件上的指示器装置的亮度进行控制,例如,房间越亮,指示器装置的亮度就越高。 In some embodiments, the PCD can be controlled the brightness of the light indicator device on the keyboard accessory keyboard accessory according to the environment in the surrounding environment, e.g., the brighter the room, the higher the luminance of the indicator device.

[0067] 尽管上文描述了与PCD和键盘附件有关的命令,但是应当注意,能够实现PCD附件协议的任何设备都可以使用这些命令来发送和接收数据。 [0067] Although a keyboard command with the PCD and related accessories hereinabove, it should be noted that any device capable of PCD accessory protocol are implemented may transmit and receive data using these commands.

[0068] 如上所述,P⑶和键盘附件可以使用P⑶附件协议彼此通信。 [0068] As described above, P⑶ keyboard accessory and accessory protocol P⑶ can communicate with each other. 在一种实施例中,P⑶ 可以接收通过P⑶附件协议而发送的命令,并能够对该命令进行解释以根据该命令中包含的信息来确定按键下压事件。 In one embodiment, P⑶ may receive a command transmitted by P⑶ accessory protocol and the command can be interpreted to determine the pressure of key press events based on the information included in the command. 图6图示了根据本发明的实施例的便携式计算设备中包含的软件栈600,它可以用来对通过遵守PCD附件协议的分组而从附件接收的命令进行解释,这些命令可以包括USB HID报告。 Figure 6 illustrates a portable computing device software embodiment of the present invention comprises a stack 600, it can be used for compliance by PCD accessory protocol packet is carried out from the command interpretation attachments received commands may include a USB HID report . 软件栈600例如可以在图3的PCD 300的处理器302中实现。 Software stack 600 for example, processor 302 may be implemented in a PCD 300 of FIG. 3.

[0069] P⑶内的协议守护程序(daemon) 602可以对P⑶附件协议通信进行控制。 [0069] Protocol daemon (daemon) within P⑶ 602 may be controlled P⑶ accessory communication protocol. 在一种实施例中,协议守护程序602可以接收由外部设备(例如键盘附件)发送的P⑶附件协议分组,提取命令和任何相关的数据,并向协议管理器606递送该消息。 In one embodiment, the protocol daemon 602 may receive P⑶ accessory protocol transmitted by an external device (e.g., keyboard accessory) packet, extracting the command and any associated data, and to the protocol manager 606 to deliver the message. 在另一种实施例中,协议守护程序602可以从协议管理器606接收包含PCD附件协议的命令和数据的对外消息, 并可以产生包含该消息的分组并将该分组传输到与PCD相连的附件(例如键盘附件)。 In another embodiment the external message, protocol daemon 602 may receive commands and data comprising the PCD accessory protocol from the protocol manager 606 embodiment, and may generate a packet containing the message and the packet is transmitted to the accessory is connected to the PCD (e.g., keyboard accessory).
