CN102053713A - Method for avoiding conflict during simultaneous clicking of 8 keys of computer keyboard - Google Patents

Abstract

The invention discloses a method for avoiding conflict during simultaneous clicking of 8 keys of a computer keyboard. Key mapping of a space key is defined as (C9, R6). By the method, the 8 keys can be simultaneously pressed down, so that functions capable of being finished by the keyboard can be extended, and an application range of the keyboard is expanded.

Description

Computor-keyboard 8 keys are with hitting the implementation method of not conflicting

Technical field

The invention belongs to field of computer technology, specifically be meant a kind of same method of not conflicting of hitting of 8 keys on the computor-keyboard that realizes.

Background technology

Progress along with science and technology, driven the development of amusement, particularly for the teenager, computer game is the important element that they enrich one's life, Games Software now is varied, much all need the player to send the operational order of many types, and operation for convenience, except using mouse to realize the control function of fraction, all to different key combination should be arranged, this just requires employed keyboard to support that multiple instruction sends simultaneously in a lot of instructions, and guarantee that this instruction can correctly be discerned differentiation by system, do not produce shielding or conflict phenomenon, the player could really outmatch among the recreation like this, enjoys the enjoyment that recreation brings.

Yet, present common on the market keyboard, owing to be subjected to the restriction of factors such as volume, the interface limited amount of chip, therefore, need be when design with interface of several key-press sharings, specifically, it is to intersect in length and breadth node by 18 horizontal 8 vertical data signal lines to be communicated with and to trigger electric signal that keyboard sends a signal to main frame, can be simultaneously with reference to shown in Figure 1, keyboard MCU is by producing particular code (this code is according to international communication agreement Unified coding) to electric signal identification to determine user command, code sends to main frame with the form of simulating signal, by operating system the simulating signal that host port detects is resolved, be converted into digital signal and by computer Recognition, because keyboard IC periphery can provide the number of pins of data circuit not reach the actual quantity of keyboard, therefore one or more buttons need a shared horizontal or longitudinal data line, when a shared data line, promptly be called " rail key " each other just as button at same track, A as shown in fig. 1, S, D, F, J, K, L be rail key each other just, like this, when these several buttons are pressed simultaneously, system can't discern, and by analyzing as can be known, this kind defined matrix can only support 7 keys simultaneously by not conflicting at most, when pressing 8 buttons simultaneously, system just can not discern, and has so just restricted the application of keyboard in a lot of recreation, as popular strength philharmonic society, Audition etc., some operation wherein can only be finished by mouse, thus the excitement of influence recreation.With space bar (Space) is example, and it is defined in the point of crossing of the 11st row and the 3rd row, also be its coordinate for (C11, R3), with its each other the rail key ESC, G, H, F4 arranged, F6, for the four direction key, its key position definition is respectively: ← (C14, R5), ↑ (C14, R3), → (C12, R5), ↓ (C11, R5), like this, according to employed communication protocol, when pressing space bar and any a plurality of directionkeys simultaneously, can not realize any function as can be known.

In view of above-mentioned analysis, the inventor only can realize that at present keyboard 7 keys with hitting the present situation of not conflicting, carry out the definition of key position again to the matrix point of crossing of keyboard, and to realize 8 keys with hitting the purpose of not conflicting, this case produces thus.

Summary of the invention

Fundamental purpose of the present invention is to provide a kind of computor-keyboard 8 keys with hitting the implementation method of not conflicting, and it can realize pressing at most simultaneously 8 buttons, thus the achievable function of extended keyboard, the usable range of enhancing keyboard.

In order to reach above-mentioned purpose, solution of the present invention is:

A kind of computor-keyboard 8 keys are with hitting the implementation method of not conflicting, the key position of space bar is defined as (C9, R6).

After adopting such scheme, the present invention is by changing the keyboard key position definition of space bar in the matrix in length and breadth, can produce signal encoding to the point of crossing by system changes, make original with the different rails of rail key, thereby realize that 8 keys do not conflict with hitting, expanded the range of application of keyboard, can realize more function, thereby can substitute the use of mouse better, more convenient to operate, quick.

Description of drawings

Fig. 1 is existing key position, the employed matrix of keyboard point of crossing definition synoptic diagram;

Fig. 2 is key position, a matrix provided by the present invention point of crossing definition synoptic diagram.

Embodiment

Below in conjunction with drawings and the specific embodiments content of the present invention and beneficial effect are elaborated.

With reference to shown in Figure 2, the invention provides a kind of computor-keyboard 8 keys with hitting the implementation method of not conflicting, it mainly is the key position definition by the matrix point of crossing that changes keyboard, it specifically is the definition that changes space bar (Space), its coordinate position is adjusted into (C9, R6), this moment its with (which button) rail key each other, as can be known when pressing A, S, D, F, J, K, L and space bar simultaneously, these 8 buttons can't clash, thereby realize that 8 keys do not conflict with hitting, expanded the function of keyboard in recreation, make that recreation is more convenient, quick.

Simultaneously, owing to changed the key position definition of space bar, make space bar to constitute special function keys jointly with the four direction key, the function of specific implementation has:

(1) press simultaneously space bar and ←, ↓, realize function

(2) simultaneously space bar and ←, realize function

(3) simultaneously space bar and →, ↓, realize function

(4) simultaneously space bar and →, ↑, realize function

).

According to keyboard provided by the present invention, its concrete use is:

(1) after computer and keyboard connect, keyboard begins input end is detected, when detecting input end generation high level, will all I/O mouths be scanned, scanning key all can write down the state of current key-press status each time, judges that earlier whether button is effectively genuine, judges whether the rail key afterwards again, and carry out relative recording, exist in the register;

(2), will send the errorless code of last judgement to computer if do not have the rail key and be the validity of relative recording;

(3) after sending code, keyboard MCU self check is to odd even effect position, if correct, expression is to send successfully.

Above embodiment only for explanation technological thought of the present invention, can not limit protection scope of the present invention with this, every technological thought that proposes according to the present invention, and any change of being done on the technical scheme basis all falls within the protection domain of the present invention.

Claims (1)

1. computor-keyboard 8 keys is characterized in that with hitting the implementation method of not conflicting: the key position of space bar is defined as (C9, R6).
