Referring to fig. 1, the electronic device includes at least two keys 2 and the key operation detection device 1, where the at least two keys 2 are connected to the key operation detection device 1. In this embodiment, the key 2 specifically refers to a physical key. In other embodiments, key 2 may also be a virtual key.

The embodiment of the invention also provides a key operation detection method which is applied to the key operation detection device and is used for detecting the key operation executed by the user on the electronic equipment. It should be noted that the key operation detection method according to the embodiment of the present invention is mainly directed to key operation detection of an electronic device having at least two keys. In other embodiments, the key operation detection method according to the embodiments of the present invention may also be applied to key operation detection of an electronic device having one key.
Referring to fig. 2, an embodiment of a key operation detection method according to the present application is provided. In this embodiment, the key operation detection method includes:
step S10, detecting key events, and sequentially storing key information corresponding to each detected key event according to a first sequence, wherein the first sequence is the sequence of detecting each key event;
the key event is specifically an action event generated when a key is triggered by a key operation of a user. The key event specifically includes a key being pressed and a key being released.
After the electronic equipment is powered on or the electronic equipment runs a preset mode, detecting a key signal output by each key in real time, and determining a key event generated by each key according to the key signal.
And when a key event is detected, determining and storing key information corresponding to the key event, wherein the key information corresponding to the detected key event is stored at a preset position firstly, and the key information corresponding to the detected key event is stored at the preset position secondly. The preset position is specifically a preset storage area for storing key information to be identified.
In the process of storing the key information of each detected key event according to the first sequence, if the key events of different keys are detected at the same time, the key information corresponding to the key event detected at the same moment can be stored in sequence according to the corresponding preset sequence among the keys, and then the step of storing the key information of each detected key event according to the first sequence is returned; if the key events of different keys are not detected simultaneously, the step of storing the key information of each detected key event according to the first sequence can be maintained. The preset sequence can be a default configuration sequence of the system or a set sequence according to the operation habit of the user.
The key information is specifically information related to key events and used for key operation identification. Each key event has a corresponding key information. The key information corresponding to different key events is different. In this embodiment, the key information corresponding to the key event includes a key identifier, a key event type, and a time when the corresponding key event is detected. The key identifier is a unique identifier for distinguishing a corresponding key from other keys, and may be a key name or a key number. The key event types specifically include a first type indicating that the corresponding key is pressed and a second type indicating that the corresponding key is released. The time when the key event is detected is specifically the time when the key event occurs. In other embodiments, the key information may include a control code corresponding to the key event, such as a control code of a pressed key 1, b of released key 2, and the like, in addition to the key identifier, the key event type, and the time when the corresponding key event is detected.
And step S20, sequentially reading each piece of key information according to a second sequence, and determining key operation according to the sequentially read key information, wherein the second sequence is the sequence for storing each piece of key information.
The key operation is specifically an operation performed by a user on a key to input a target instruction to the electronic device.
Specifically, in the process executed in step S10, the timing may be started every time a key event is detected, and step S20 may be executed when the timing duration is greater than the set duration and the next key event is not detected. Or, the timing may be started when the detection of the key event is started, and the step S20 may be executed when the timing duration reaches the preset period. Alternatively, in the process of step S10, the number of pieces of key information already stored is counted, and step S20 is executed when the number of pieces of key information is greater than the set number. The set number is less than or equal to the maximum number of key information allowed to be stored in the preset position.
Specifically, the key information stored first is read first, and then the key information stored later is read. Specifically, successively read key information is analyzed according to the identification rule of the key operation, and the operation corresponding to the read key information is obtained. The key operation may be one or more than one, and when the key operation is more than one, the key operation may include a key operation corresponding to a different key or more than one key operation corresponding to the same key.
According to the key operation detection method provided by the embodiment of the invention, in the process of detecting the key time, the key information corresponding to each key time is sequentially stored according to the detection sequence of each key event, the stored key information is further sequentially read according to the storage sequence of each key event, and single-time operation is determined according to the sequentially read key information.
Further, based on the above embodiments, another embodiment of the key operation detection method of the present application is provided. In this embodiment, referring to fig. 3, the step S10 includes:
step S11, detecting key events, and writing the key information corresponding to each detected key event into a first-in first-out queue in sequence according to the first sequence;
based on step S11, step S20 includes:
step S21, sequentially reading each piece of key information according to the writing order of each piece of key information in the fifo queue.
The fifo queue is specifically a data structure that performs data insertion and deletion on the basis of fifo. The fifo queue may specifically determine the maximum number of storage elements allowed for the electronic device according to the number of keys on the electronic device.
The key information corresponding to each detected key event can be written into the tail of the queue as a new element, and the ranking of the key information corresponding to the detected key event in the queue is prior to the ranking of the key information corresponding to the detected key event in the queue.
When the key information is read, the key information is read from the queue in sequence according to the order of the bits arranged in the queue.
In this embodiment, the first-in first-out queue is used for storing and reading the key information, so as to further ensure the orderliness and accuracy of key information detection in the key operation identification process, and further improve the accuracy of key operation identification of a user on the electronic device. And the first-in first-out queue is used for storing and reading the key information, the key information can be read in a non-blocking mode, and the key information can be read without waiting for the completion of the key dithering filtering processing, so that the orderliness and the accuracy of key information detection are further improved, and the accuracy of key operation identification of a user is further improved.
Further, in this embodiment, the key operation detection method further includes: executing the step of detecting the key event and starting timing to obtain a first timing duration; when the first timing duration is less than or equal to a first preset clock period, executing the step of sequentially writing the key information corresponding to each detected key event into a first-in first-out queue according to the first sequence; and when the first timing duration is longer than the first preset clock period, executing the step of sequentially reading each piece of key information according to the writing sequence of each piece of key information in the first-in first-out queue.
The first preset clock period may be specifically determined according to preset types of all allowed key operations of the electronic device, the number of keys on the electronic device, and/or the maximum number of allowed storage elements of the fifo queue, and the like. Different key operation types, different numbers of keys and/or different maximum allowable storage numbers correspond to different first preset clock cycles.
And continuously detecting the key events when the first timing duration does not reach a first preset clock period, sequentially writing the key information of the detected key events into the first-in first-out queue according to the detected sequence, and sequentially reading the key information according to the writing sequence when the first timing duration exceeds the first preset clock period.
The key information can be deleted from the head of the first-in first-out queue every time the reading of the key information is finished, so that the element quantity stored in the first-in first-out queue can not exceed the maximum allowable quantity; or deleting the key information in the first-in first-out queue after finishing reading all the information in the first-in first-out queue. In addition, in the process of reading the key information, the key event can be kept and detected, the key information of the newly detected key event is written into the tail of the first-in first-out queue, and if the number of the key information currently written into the first-in first-out queue reaches the allowed maximum number, the head of the current first-in first-out queue can be used as the new tail of the queue.
In this embodiment, the trigger time for starting reading the key information is limited by the first preset clock period, which is beneficial to further ensuring that the storage and writing processes of the key information are not blocked, so as to further improve the accuracy of key operation identification of a user on the electronic device. Moreover, the reading of the key information can be regularly executed in the tick timer, and the detection in the main program is not needed all the time, which is beneficial to reducing the resource consumption of the embedded system.
Further, in this embodiment, after the step of executing the step of detecting the key event and starting timing to obtain the first timing duration, the method further includes: when the first timing duration is longer than the first preset clock period, starting timing to obtain a second timing duration; when the second timing duration is less than or equal to a second preset clock cycle, executing the step of sequentially reading each piece of key information according to the writing sequence of each piece of key information in the first-in first-out queue; and when the second timing duration is longer than the second preset clock cycle, returning to the step of executing the key event detection and starting timing to obtain the first timing duration.
The second preset clock period may be specifically determined according to the first preset clock period, the preset types of all allowed key operations of the electronic device, the number of keys on the electronic device, and/or the maximum number of allowed storage elements in the fifo queue. The different first preset clock cycles, the key operation types, the different key numbers and/or the different maximum allowable storage numbers correspond to different second preset clock cycles.
And continuously reading the key information in the first-in first-out queue according to a second sequence when the second timing duration does not reach a second preset clock cycle, and re-detecting the key event when the second timing duration exceeds the second preset clock cycle.
In this embodiment, the second preset clock period is used to limit the key information reading duration and trigger the time for detecting the next key operation, so as to further ensure that the storage and writing processes of the key information are not blocked, and different key operations of the user can be accurately distinguished, so as to further improve the accuracy of key operation identification of the user on the electronic device. Moreover, the reading and writing of the key information can be periodically executed in the tick timer, and the detection in the main program is not needed all the time, which is beneficial to reducing the resource consumption of the embedded system.
Further, based on any of the above embodiments, a further embodiment of the key operation detection method of the present application is provided. In this embodiment, referring to fig. 4, the step S21 includes:
step S211, acquiring a first quantity of key information currently written in the first-in first-out queue;
specifically, the preset identification value is used for representing the number of the key information currently written in the first-in first-out queue. The initial value of the identification value is 0, the numerical value of the identification value is increased by 1 every time one piece of key information is written in the first-in first-out queue, and the numerical value of the identification value is decreased by 1 every time one piece of key information is deleted from the first-in first-out queue.
Based on this, reading the current identification value may obtain the first number here.
Step S212, reading the target key information, and updating a second quantity of currently read key information in the first-in first-out queue; the target key information is key information with the most front arrangement order in the key information which is not read currently in the first-in first-out queue;
the second number is updated once each time one key information in the FIFO queue is read. Specifically, the information in the first-in first-out queue is read before and after the information is read, and the updated second number is obtained after the current second number is increased by 1.
Step S213, if the second quantity is smaller than the first quantity, determining new target key information according to the writing sequence, returning to execute the step of reading the target key information, and updating the second quantity of the currently read key information in the first-in first-out queue;
specifically, the key information arranged one bit after the current bit in the fifo queue is used as new target key information, and then the new target key information is read and the second amount is further updated.
Step S214, if the second number is the first number, ending reading the key information in the fifo queue.
After step S214, the key operation may be determined according to all currently read key information.
Further, after step S214, the step of detecting key events and sequentially storing the key information corresponding to each detected key event according to the first sequence may be returned. Further, after step S214, the step of detecting the key event and starting to count the time to obtain the first counted time length may be returned to.
In order to better understand the technical solution designed in this embodiment, the following description is given by taking five fifo queues as an example with reference to fig. 5:
the Write variable indicates the Write position and the Read variable indicates the Read position. In the initial state, as shown in fig. 5(a), Read is 0, and null in the fifo queue indicates that there is no written key information. If the keys K1 and K2 are pressed in sequence, the key information of the events of K1 pressing, K1 bouncing, K2 pressing, and K2 bouncing are sequentially stored in the fifo queue, and the data in the fifo queue becomes (b) of fig. 5. Wherein, K1, K2 are characterized by key identification, Up is characterized by key being released, Down is characterized by key being pressed.
Every time one key information is Read from the first-in first-out queue, 1 is added to Read, and the Wrie variable is unchanged; and every time one piece of key information is stored in the first-in first-out queue, Read is unchanged, and the Write variable is added with 1. If a key information is Read from the fifo queue in fig. 5(b), Read becomes 1 and Write remains 4; when three key events continue to be Read from the FIFO queue, Read becomes 4 and Write remains 4. At this time, the two variables are equal, which means that all key events are processed, no new key event is processed, and at this time, the key event can be continuously detected until new key information is written into the first-in first-out queue.
In this embodiment, through the above manner, it can be ensured that the key information corresponding to all key times is not missed in the key operation identification process, thereby further improving the accuracy of key operation identification.
Further, based on any of the above embodiments, a further embodiment of the key operation detection method of the present application is provided. In this embodiment, any two pieces of successively read key information are defined as first key information and second key information in sequence, with reference to fig. 6, step S30 includes:
step S31, when the first key information and the second key information meet the preset condition, determining a time difference value between the second time and the first time; the preset conditions include that the first key information and the second key information both include the same target key identification, the key event type in the first key information is that a key is pressed, and the key event type in the second key information is that a key is released, the first time is the time for detecting the corresponding key event included in the first key information, and the second time is the time for detecting the corresponding key event included in the second key information;
step S32, when the time difference is smaller than or equal to a set threshold, determining that the key operation is a short-press operation of the key corresponding to the target key identification;
step S33, when the time difference is greater than the set threshold, determining that the key operation is a long-press operation of the key corresponding to the target key identifier.
For example, there are 4 pieces of key information read, which are K1 Down T1, K1 Up T2, K2 Down T3, and K2 Up T4, where K1 and K2 denote key identifiers, Up denotes a key released key event, Down denotes a key event in which a key is pressed, and T1, T2, T3, and T4 denote occurrence times corresponding to the key events, respectively. Based on the above, the key identifications of the first key information and the second key information are both K1, and the first key information detected firstly contains the information that the key is pressed, and the second key information detected later contains the information that the key is released, so that the key operation of the K1 key can be a long press or a short press according to the comparison of T2-T1 and the set threshold value; the key identifications of the third key information and the fourth key information are both K2, and the first detected third key information contains information that the key is pressed, and the second detected fourth key information contains information that the key is released, so that the key operation of the K2 key can be a long press or a short press according to the comparison of the T4-T3 and the set threshold value.
In the embodiment, by the mode, the long-press operation and the short-press operation of different keys can be accurately distinguished, so that the accuracy of key operation identification of different key durations on the electronic equipment is guaranteed to be improved.
In addition, an embodiment of the present invention further provides a computer-readable storage medium, where a key operation detection program is stored on the computer-readable storage medium, and when the key operation detection program is executed by a processor, the relevant steps of any embodiment of the above key operation detection method are implemented.
