TW200803185A - Process method of keyboard signal - Google Patents

Abstract

A process method of keyboard signal for using keyboard more flexible is described. The process method of keyboard signal comprises a normal mode and a scan address mode that are switched by a switch command. When the keyboard at the normal mode, the keyboard transmits a scan code of an action key to a host. When the keyboard at the normal mode, keyboard directly transmits an address code of the action key to the host, and then the host transforms the address code to the scan code by a mapping table. Wherein the mapping table can be a custom-made mapping table and implemented by software of firmware. So that, according present invention, the application of the keyboard is more flexible than prior.

Description

200803185 IX. Description of the Invention: [Technical Field] The present invention relates to a signal processing method, and more particularly to a signal processing method for a keyboard. [Prior Art]

Second, please refer to the schematic diagram of the first schematic signal transmission wheel of the first figure. The known keyboard ## is generated by the keyboard ίο a keyboard scan code PS/2 packet signal η to the host 12, the host 12 directly according to the keyboard scan code ^ ^ package ^ number ^ for the operating system in the host 12 to perform related actions ό Μ When the button on the keyboard 10 is pressed or released, the keyboard can obtain the (four) code of the pressed/release button. The obtained address code is converted into a scan code by a mapping table set in the keyboard. The scan code of the press/release button is then converted to the p s / 2 packet signal i i , and the _ table is set to the keyboard 1G towel, and the relationship between the wire and the keys on the keyboard 10 has been set. In other words, the functions and definitions of the keys on the keyboard 1Q are fixed when the keyboard 10 is shipped from the factory. Therefore, the user is limited to the preset (4) function (4) in use, and thus the keyboard is not enough to be applied in the application. :. ~ In view of the above, the present invention provides a keyboard signal processing method to improve the keyboard (4), the first step is to determine the top of the disk = whether there is a button action; if so, the button is obtained One address code. Then, the address code of the button is converted into a PS/2 packet and then transmitted to the machine', and then the address code of the button is converted into the button in the charm machine towel. 200803185 A job is taken and cut as a button The scan code is outputted to the host by the key _ weight =: two:: J port: number processing method, the steps include whether there is a button action first; if =|^^ 该 test the keyboard key matrix in the next ^接_ Laizhi material code to - host.

Then the keyboard is pressed to scan the address mode. Then send the address of the button = the address code is converted to the code 1 of the button (4) The host can change the address code to scan the code on the host.

_ send and define the host's mapping table (four) I right person on the keyboard to set the M 1 ^ 1 ☆ method, do not need to be like the knowledge of the Μ Μ 之 之 之 键盘 键盘 键盘 键盘 键盘 Η Η Η Η Η Η Η Η Η Η Η Η Η The mapping table is more flexible and flexible in the definition of keyboard keys. ,

In order to further understand the techniques, means, and effects of the present invention in order to achieve the intended purpose, refer to the following detailed description of the invention and the accompanying drawings. It is to be understood that the invention is not to be construed as limiting the invention. Embodiments k will be described in detail with reference to the preferred embodiments of the present invention. Please refer to the second figure of the first preferred embodiment of the keyboard signal processing method of the present invention. Firstly, the button action on the keyboard is detected, and the button action is performed by pressing and releasing (pressed/deprasd) the button to open and close the node in the key matrix (as in the second step S2〇1). Detecting the keystrokes on the keyboard by using the 200803185, the address code of the key-like action button (such as the first step = the address, the device can obtain the address code to be converted into the scan code, and will move. 鍅『 Then the first packet will not be 'And through the - Saki noodle to the code to the body of the seal and then set by the host map 7 - Figure step illusion 5). The code (such as step S207 in the second figure) === the address code is converted to the operating system scanned to the host, and the scan code of the = key is rotated out of S209. The mapping table set by the host is turned off/as the second The step-by-step mapping table can be used in the host 々山田: it is a custom function of the original body or software:: Improve the function of the keyboard keys and its application - the fifth picture of the invention The signal processor first turns on the power-on keyboard (for example: :: =.=? After the keyboard signal processing mode is -峨^重^乍i =) °# in the normal mode, the lower keyboard has a button ' /, button The action is that the button is pressed and released, P is d/^pressed), and the S-force 3 of the node in the keyboard matrix is turned on and off: step S3〇5). If there is no button action, return to the step ΙΙίΓ一ί mode is on standby. If there is a button action, the address of the action button is obtained in the button matrix of the scanned address, and the address code is converted to the scan code by using the first mapping table. The scan code is converted into a PS/2 packet and the scan code of the action button is output to the main through the ps/2 interface. (Step S3〇7 in the third figure) However, in the step S3〇3 in the normal mode, in addition to detecting whether there is a key action step S3〇5, the same g detects whether a switching command is received (such as the third Step S3〇9). If no switching success is received, return to step S303 and the keyboard continues to be in the normal mode. If the keyboard receives the switching command, the keyboard signal processing mode is changed to 200803185 5 address mode (such as the third Figure s3u. In the case of detecting whether there is a button on the keyboard, if there is no button action, then return to the step-step, step S3! 3). f-key action 'Miscellaneous_彳晴! If there is (10) interface will Two = two, the packet, and then through S 315). Then in the live machine. S, out, the host (such as the third step step code, to transfer the host money ^ mapping table to change the address code to sweep in Steps are in the swollen position ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Key: connect:, back to the step order, then the tree, please 3 keyboard lm === life and the above city The command is shot as _ on (4) computer peripheral devices, such as H jin, or other sighs of the main sigh, the mapping table can be a toughened mapping table, can be used on the host side to open the soft body = The key of each key to improve the keyboard function is described in the application. It is only the details of the specific embodiment of the present invention. 'All the scope of the present invention should be based on the following application. The spirit of the scope of the patent application of the present invention and its similar variations are all included in the age towel of the present invention, and any of the familiar (4) items can be easily changed or modified. The first figure is a schematic diagram of a conventional keyboard signal transmission; the second figure is a motion chart of the keyboard signal processing method of the present invention; and the preferred embodiment of the preferred embodiment The three figures are the flow chart of the action of the keyboard signal of the invention.
