Problems solved by technology
However, after the current keyboard has gone through steps such as keyboard detection and scanning, and checking whether there are ghost keys, the response time of the keyboard will be increased instead.
In this way, if the user is using it in normal times or in e-sports, it will not only cause inconvenience to the user, but may also affect the performance of the user in competition due to ghost keys or key position problems

Embodiment Construction
[0019] In order to make the above-mentioned features and advantages of the present invention more comprehensible, the following specific embodiments are described in detail in conjunction with the accompanying drawings.
[0020] Please refer to figure 1 , figure 1 It is a schematic diagram of an input device 10 according to an embodiment of the present invention. The input device 10 is used in a computer system, and includes a controller 102 , a plurality of input elements 104 , an address register 106 and a data register 108 . Each input element 104 is independently connected to the controller 102 . When each input element 104 is tapped or operated, a corresponding interrupt signal will be generated. That is to say, each input element 104 and the controller 102 have a one-to-one correspondence structure. The controller 102 stores state information when the plurality of input elements 104 are triggered through the address register 106 . The data register 108 is used to st...

The invention provides a state detection method of an input device. The method comprises the following steps of: when a plurality of input elements of the input device are triggered, generating a plurality of interrupt signals corresponding to the plurality of input elements; setting a plurality of interpret flags corresponding to the plurality of input elements according to the plurality of interrupt signals; transmitting a scanning code corresponding to the plurality of first interrupt flags in the plurality of interrupt flags to a computer system according to the plurality of first interrupt flags, wherein the quantity of the plurality of first interrupt flags is related to the capacity of an address buffer; clearing the plurality of first interrupt flags in the plurality of interrupt flags; and detecting at least one second interrupt flag which is not cleared in the plurality of interrupt flags, and transmitting a scanning code of an input element corresponding to the at least onesecond interrupt flags to the computer system.
Description
technical field [0001] The invention relates to a state detection method and device for an input device, in particular to a method for detecting the state of an input device element by interrupt processing and a related device. Background technique [0002] With the development of information technology, the rise of e-sports has led to the vigorous development of related products. Generally speaking, the performance of peripheral electronic equipment in e-sports often directly affects the performance of contestants, and then becomes the key to the outcome. For example, the response speed of the keyboard and mouse, the probability of peripheral equipment to produce wrong responses, etc. Because the keyboard of the current matrix array formula needs to scan (Scanning) the signal lines of the keyboard array line by line to confirm the position of the pressed key in the keyboard matrix when detecting that the key is struck, and according to the position by checking Get the sca...
