Abstract

The invention provides a keyboard matrix analysis structure, comprising a master control chip for receiving the signal of the keyboard interface and the mode change-over switch, controlling the scanning of the system and analyzing and displaying the results, a keyboard interface for connecting the keyboard and the master control chip, an LED display board for receiving the output signal of the master control chip and displaying the row and queue where the key is positioned and analysis result of the row and queue of the keyboard, a communication module of COM (Component Object Model) port for receiving the output signal of the master control chip, outputting the analysis result to the computer, and updating the program of the master control chip, and a mode change-over switch for switching the scanning mode and the analysis mode of the system. The keyboard matrix analysis structure and analysis method are utilized, the position information of the key is acquired by the system in the scanning mode via pressing the key; the system enters into the analysis mode by pressing all keys to output the distribution information of the row line, the queue line and the free line of the keyboard. The whole analysis process has short time, high efficiency, simple and convenient operation.

Description

technical field [0001] The invention relates to a keyboard matrix analysis structure and method, in particular to the analysis structure and method of a matrix keyboard array. Background technique [0002] The keyboard is the most common computer input device, which is widely used in microcomputers and various terminal devices. Computer operators input various instructions and data to the computer through the keyboard to direct the work of the computer. The operation of the computer is output to the monitor, and the operator can easily use the keyboard and monitor to talk to the computer, modify and edit the program, control and observe the operation of the computer. In the development process of the notebook computer, the keyboard is the main means of interaction between the outside world and the computer, and the development of keyboard-related functions plays a decisive role in the development of the entire system. [0003] The matrix keyboard is formed by interweaving ...
