101. and when a plurality of keys in the electronic equipment are pressed, acquiring row line coordinates and column line coordinates of the plurality of keys.
As shown in fig. 2, a key matrix structure of a native key module is shown, wherein ROW0 to ROW5 are 6 key ROW lines in the native key module, COL0 to COL 6 are 7 key column lines in the MTK native key module, the native key module supports a ROW-column key matrix design of maximum 6*7, and there are 42 keys (S0 to S41 in fig. 2), in the embodiment of the present application, the key ROW lines are all configured to output a low level mode, the key column lines are set to an interrupt mode, and the low level is triggered; when a certain key is pressed, the corresponding row line is short-circuited, and the interrupt is triggered.
Thus, in an embodiment of the present application, before the plurality of keys are pressed in the electronic device, the method further includes: configuring the plurality of key row lines to output a low level mode; and configuring the plurality of key column lines into a low-level interrupt trigger mode.
In some embodiments of the present application, when a plurality of keys in the electronic device are pressed, acquiring row line coordinates and column line coordinates of the plurality of keys includes:
(1) And when a plurality of keys in the electronic equipment are pressed, determining a target key column line for detecting the pressing of the keys.
Wherein, when the plurality of keys in the electronic device are pressed, determining a target key column line for detecting the pressing of the keys, and further comprising: when a plurality of keys in the electronic equipment are pressed, determining a target key column line outputting low level; and storing the key column line value corresponding to the target key column line in a preset array, and marking the number of key column lines in the target key column line. At this time, the target key column line is determined, that is, the column line coordinates corresponding to the plurality of keys are determined.
In the following, a specific example is described as an example, when a plurality of keys in the electronic device are pressed, a target key column line COL of the plurality of keys is confirmed, reading of all COL gpio lines detected to be low level is mainly completed, a key column line value corresponding to the target key column line is stored in a preset array col_low, and a total count of COL gpio detected to be low level is M. The method comprises the following specific steps: all ROW gpio is set to output low level in the initial state, at this time, COL gpio is set to read mode, if low level is detected, it is indicated that there may be one or more key presses on this COL gpio line, but specifically which ROW gpio triggers, and it cannot be confirmed. The COL gpio (case column line value corresponding to the target key column line) detected as the low level is stored in the col_low array, and the number of key column lines in the target key column line is denoted as M.
(2) And traversing and detecting all keys corresponding to the target key column line, and determining the keys which are detected to be pressed down as the plurality of keys.
Similarly, by way of a specific example, all the keys corresponding to the target key ROW line are detected, the key pressed by the key detected in all the keys corresponding to the target key ROW line is determined as one of the plurality of keys, and at this time, ROW line coordinates and column line coordinates of the plurality of keys, that is, ROW coordinates and COL coordinates as shown in fig. 2, can be sequentially determined, so that the positions of the physical keys in the plurality of keys can be determined.
The method comprises the following specific steps: assuming that there are M key column lines in total in the target key column lines, that is, the low-level COL line is detected in the M key column lines, at this time, all keys corresponding to each key column line are sequentially traversed from the 1 st key column line to the M key column line in the M key column lines (as shown in fig. 2, all keys corresponding to the COL1 column line are S0, S7, S14, S21, S28 and S35, respectively), and the determination of the key detected to be pressed by the key is one of the plurality of keys. And sequentially calculating to obtain the positions of all the pressed keys on the corresponding target key column line.
Traversing all keys corresponding to each key column line, and confirming that the key in the key column line is one of a plurality of keys comprises the following steps: for a key column line col gpio where a key press has been detected, the row gpio position, i.e. row coordinates (row line coordinates), of all key presses on this key column line can be located and the coordinates of the final key are recorded. The specific implementation is as follows: on a given nth col line, if the nth col is output low level and the other cols are output high level, the level value is read from the row gpio, and if the low level is detected at three positions a, b and c of the row gpio, it is indicated that the key is pressed at three positions (a, N) (b, N) (c and N).
The following is exemplified by the case that only one column line and a plurality of column lines in the target key column lines are used, if m=1, that is, the target key column lines include 1 key column line, S10 (row 1, col 3), S17 (row 2, col 3), S24 (row 3, col 3), and simultaneously, the preset col_low array has only 1 key column line, that is, m=1, col 3gpio, because all keys are on the col 3 key column line; at this time, only once, since col_low has only 1 col 3, the physical key coordinates of the plurality of keys can be read as (1, 3), (2, 3) and (3, 3) by traversing all keys corresponding to the key column line col 3.
If m=3, i.e. the target key row line includes 3 key row lines, it is assumed that S16 (row 2, col 2), S24 (row 3, col 3), S232 (row 4, col 4), and pressing at the same time, since there are only 3 col_low arrays, respectively col 2, col 3, col 4, m=3; cases corresponding to 3 key column lines need to be traversed and detected respectively, and (2, 2) can be obtained on the assumption that n=2 is the first time; second time n=3, (3, 3) can be obtained, and third time n=4, (4, 4) can be obtained.
(3) And acquiring row line coordinates and column line coordinates of the plurality of keys.
After the positions of the keys are determined, row line coordinates and column line coordinates of the keys can be obtained.
102. And calculating key values of the plurality of keys according to row line coordinates and column line coordinates of the plurality of keys.
The method specifically includes the steps of calculating key values of the plurality of keys according to row line coordinates and column line coordinates of the plurality of keys, wherein the key values comprise: and respectively taking each key in the plurality of keys as a target key, and calculating a key value of the target key according to row line coordinates and column line coordinates of the target key.
Further, calculating the key value of the target key according to the row line coordinate and the column line coordinate of the target key may include: calculating the sum of the row line coordinates of the target key and the column line coordinates of the target key; and taking the sum value as a key value of the target key. Taking the column line coordinates and the row line coordinates of the target key as 6 and 3, respectively as an example, the key value of the target key is 6+3=9.
103. And performing key mapping on the plurality of keys according to the key values of the plurality of keys to obtain target key events corresponding to the plurality of keys.
The key value of each key corresponds to the key (physical key value) of the bottom layer, for example, a certain key value is 9, and corresponds to the bottom layer physical key S9, but in a specific application scene of the electronic device, the key value needs to be analyzed and mapped into various key values of the upper layer, for example, S22 is a key a of the bottom layer, and is mapped to a left key of an upper game interface, but is possibly a numeric key of the main interface, which is a common key design scheme, the physical layer obtains the truest key event, and the upper layer maps more and richer key functions according to the interface where the user is located. And then, after the key values are analyzed and mapped into various upper-layer key values, target key events corresponding to a plurality of keys (upper-layer key values) are acquired.
104. And executing the target key event.
Specifically, a specific module of the electronic device needs to perform corresponding processing on the target key event, for example, it is assumed that a plurality of keys are respectively S16, S24 and S32, and correspond to top keys of Ctrl, alt and Delete respectively, and a user presses the top keys at the same time and can set to enter a lock screen; and supposing that the three combination keys correspond to the roles of the game interface, the functions of the peep-proof function can be used, and then the peep-proof function can be played in combination with other conditions, so that the entertainment and the user experience of the mobile phone are improved.
In some embodiments of the present application, after one key event processing is completed, the initialization state needs to be restored, and the key interrupt event is waited for triggering, that is, the multi-key detection method may further include: after the target key event is executed, a key row line mode is reinitialized to configure the plurality of key row lines to output a low level mode and the plurality of key row lines to be configured to a low level interrupt trigger mode.
According to the embodiment of the application, the values of all key points can be read at one time, the key values do not need to be read from a register, the key detection speed is improved, the method and the device can be seamlessly combined with a native mechanism, and the code stability and portability are strong.
