Keyboard signal processing system

Abstract

The invention discloses a keyboard signal processing system which is applied to the using environment of keys of keyboards. The keyboard signal processing system comprises a first processing module and more than one second processing module. A key code of an individual key of a first group of keys in the first processing module and / or more than two key codes of the more than one second processing module will be read and transmitted to a computer end connected with a keyboard. The keyboard signal processing system solves the problems that when a user presses more than two keys at the same time in a key matrix scanning process and the key arrangement positions can not be recognized when located at the same scanning queue and / or at the same scanning line, while each pressed key can be recognized, and therefore a computer can carry out a combined function of more than two keys, for example, a multi-key instruction operation function of video games.

Description

technical field [0001] The invention relates to a signal processing system, in particular to a keyboard key matrix scanning signal processing system applied in the keyboard key use environment. Background technique [0002] For the commonly known keyboard signal processing, except for some specific multi-key signal processing situations, for example, after pressing [Ctrl]+[Alt]+[Delete] three keys at the same time, the Windows task administrator interface will appear, and for example , after pressing [Fn]+[F4] two keys at the same time, the screen will display selection. Generally speaking, when the pressed keys are arranged in the same scanning column and / or the same scanning line, it will not be able to process more than two The case where the keys are pressed simultaneously. [0003] However, as far as the current video game operation is concerned, there are often situations where the game has multiple instructions, and more than two buttons will be pressed at the same t...

Problems solved by technology

[0002] For the commonly known keyboard signal processing, except for some specific multi-key signal processing situations, for example, after pressing the three keys [Ctrl]+[Alt]+[Delete] at the same time, the Windows task administrator interface will appear, and for example , after pressing [Fn]+[F4] two keys at the same time, the screen will display selection. Generally speaking, when the pressed keys are arranged in the same scanning column and / or the same scanning line, it will not be able to process more than two When keys are pressed simultaneously

[0003] However, as far as the current video game operation is concerned, there are often situations where the game has multiple instructions, and more than two buttons will be pressed at the same time. However, the known technology cannot handle this situation. The technology cannot handle the situation that multiple keys are pressed at the same time, nor can it solve the multi-command operation of video games
