Embodiment Construction

[0017] The invention discloses a keyboard and a method for synchronizing with a host. In order to make the description of the present invention more detailed and complete, reference may be made to the following descriptions in conjunction with the accompanying Figure 1 to Figure 3 .

[0018] figure 1 A block diagram of a keyboard 100 synchronized with a host is shown according to an embodiment of the present invention. The keyboard 100 includes a key module 110 , a keyboard controller 120 , a memory device 130 and a light device 140 . The key module 110 provides the user to perform key input, such as a conventional key module with 104 keys. The keyboard controller 120 is connected to the button module 110, which can sense the input action of the button, and generate a corresponding light signal state according to the input of the button, and then transmit the light signal state to the external host to update the keyboard light signal state of the system, and The state of ...

Abstract

The invention provides a keyboard which is synchronous with a host computer, and a method. The keyboard comprises a keystroke module used for providing keystroke input for the user, a keyboard controller which is connected with the keystroke module and used for generating a corresponding lamp number signal according to the keystroke input and transmitting the lamp state to an external host computer, a memory device which is connected with the keyboard controller and used for memorizing the lamp number state, and a lamp number device which is connected with the keyboard controller and used for displaying the lamp number state, wherein, after the keyboard is initialized, the keyboard controllers leads the memory to read the lamp number state and displays the lamp number state in the lamp number device so as to lead the lamp number state of the lamp number device to be consistent to the lamp number state of the external host computer.

Description

technical field [0001] The invention relates to a keyboard and a method synchronizing with a host, in particular to a keyboard and a method synchronizing the display states of function keys with the host. Background technique [0002] There are three function indicators on traditional keyboards, such as Num Lock, Caps Lock and ScrollLock, to show the keyboard operation status. Generally, after the keyboard of the PS2 interface is plugged and pulled out, or the control IC is reset due to static interference or magnetic field interference, these three indicators will go out. However, the host system still memorizes the status before reset, which leads to the phenomenon that the indicator light is out of sync with the status of the host system. Therefore, the user may not be able to distinguish the operating state of the keyboard, causing confusion in use. Although the user can manually press one of the three keys twice to synchronize the indicator lights on the keyboard with...
