Based on the hardware architecture of the electronic equipment, the embodiment of the interaction method based on the keys is provided.
Referring to fig. 2, fig. 2 is a first embodiment of a key-based interaction method according to the present invention, where the key-based interaction method includes the following steps:
step S10, periodically monitoring the level states of the keys, and assigning the state values corresponding to the level states to the level data bits corresponding to the keys in the level variables.
Specifically, the level state of each key is monitored in real time according to a preset time interval, and the level state can be an active level and an inactive level. Wherein the active level may be a high level and the inactive level may be a low level; or the active level may be low and the inactive level may be high. The state value corresponding to the level state of the key may be a numerical value, and for example, the state value corresponding to the active level may be 1, and the state value corresponding to the active level may be 0. The level variable is a variable for recording the level state of the key, the level data bit is used for storing a state value corresponding to the level state, and the state value corresponding to the level state is assigned to the level data bit corresponding to the key in the level variable.
In step S20, if the state value of at least one level data bit is the state value of the active level, timing is started.
Specifically, when the state value corresponding to the level data bit corresponds to the state value of the active level, it indicates that the key is pressed, and in order to determine the key pressing result, the time length of the key at the active level needs to be counted. When the state values of the level data bits all become the state values corresponding to the invalid level, the timing is stopped.
Step S30, determining a key result value according to the timing duration;
specifically, the key result value is determined according to the time length corresponding to the key of the active level. The key result value may be represented in binary, and illustratively, the invalid key result value is 00, the short-pressed key result value is 01, the long-pressed key result value is 10, and the combined-pressed key result value is 11.
Step S40, assigning the key result value to a result data bit corresponding to a level data bit of a state value of which the state value is an active level in the result variable, so as to determine an interaction parameter according to the key result value in the result data bit.
Specifically, the key result value is assigned to a corresponding result data bit in a result variable, wherein the level variables of the level data bit of the key correspond to the result variables in the result data bit one to one. And determining an interaction parameter according to the key result value in the result data bit, and calling the terminal equipment according to the interaction parameter.
The preset number of keys, level data bits and result data bits may be preset in the program, and the newly added keys may be assigned to the preset keys upon detection of the newly added keys. If the preset number of keys is not preset, after the newly added keys are detected, level data bits corresponding to the newly added keys can be added to the level variable; and adding a result data bit corresponding to the newly added key in the result variable, and determining a result value of the key according to the level variable of the key. The problem that due to the fact that a plurality of keys correspond to independent detection programs, new detection programs need to be added, resource expenditure of a processor is increased in a multiple mode, the program operation period is obviously increased, and the real-time performance of the system is reduced is solved. And the application does not need to add a new detection program or repeatedly execute programs with similar functions, thereby facilitating the extension of the keys.
In the technical scheme of the embodiment, the level state of each key is monitored at regular time, timing is started when the level state is an effective level, and a key result value is determined according to the level state and timing duration. Because the state value of the level state of the key is assigned to the level data bit, the key result value is assigned to the result data bit, and the plurality of keys are uniformly detected and processed, the condition that the detection period is longer because the plurality of keys correspond to independent detection programs is avoided, and the detection and processing efficiency of the plurality of keys is improved.
Referring to fig. 3, fig. 3 is a second embodiment of the key-based interaction method of the present invention, and based on the first embodiment, after step S20, the method further includes:
step S50, if the timing duration is longer than the jitter elimination duration, executing the step of determining the key result value according to the timing duration;
step S60, if the timing duration is equal to the jitter elimination duration, determining whether the state value of at least one level data bit in the level data bits is the state value of the effective level;
in step S70, if there is no state value of at least one level data bit as the state value of the active level, the timing duration is cleared.
Specifically, the switch used for the key is usually a mechanical elastic switch, and when the mechanical contact is opened and closed, the key switch is not immediately and stably turned on when the mechanical contact is closed, and is not turned off at a moment when the mechanical contact is opened, so that the key is subjected to a series of shakes at the moment of closing and opening. The shake elimination duration is used for judging whether the key shakes, and the shake elimination duration is determined by the mechanical characteristics of the key and is generally 5 ms-10 ms. When the timing duration of the key is longer than the jitter elimination duration, the key result and the key result value need to be determined according to the timing duration, the key result may be invalid, long pressed, short pressed, or combined pressed, and the corresponding key result value may be 00, 01, 10, and 11. And when the timing duration of the key is less than the jitter elimination duration, clearing the timing duration and determining that the key result is invalid. And when the timing duration is equal to the jitter elimination duration, judging whether at least one of the key level variables is an effective level, if not, determining that the key result is invalid, clearing the key timing duration, and if so, determining whether at least two keys are combined according to the duration of the other key. The combined press is a press result including at least two press key combinations, and for example, in the a key, the b key and the c key, when the a key and the b key correspond to state values corresponding to an active level and a corresponding timing duration is longer than a jitter elimination duration, the press result values of the a key and the b key are the combined press. When the timing duration of the key is longer than the jitter elimination duration, the key result can be long press, short press or combined press. And after the key result value is determined, the timing duration is cleared, so that the detection of the next key result value is facilitated.
In the technical scheme of the embodiment, the key result value is determined by the timing duration, whether the key is effective or not can be determined, the key result of the key can be determined under the effective condition, different interaction parameters are determined according to the key result, and the interaction function is realized.
Referring to fig. 4, fig. 4 is a third embodiment of the interaction method based on keys according to the present invention, and based on the second embodiment, the step S30 includes:
step S31, comparing the timing duration with a preset duration, wherein the preset duration is greater than the jitter elimination duration;
step S32, if the timing duration is greater than or equal to the preset duration, assigning a result value corresponding to the long press to the key result value;
and step S33, if the timing duration is less than the preset duration, assigning a result value corresponding to the short press to the key result value.
Specifically, the timing duration and the preset duration are compared, the preset duration is used for judging whether the key is pressed for a long time or a short time, and the preset duration is greater than the shake elimination duration. When the timing duration is longer than or equal to the preset duration, the pressing time of the key is effective and longer, and the key result value of the key corresponds to the key result of long pressing. And when the timing duration is shorter than the preset duration, the pressing time of the key is effective but shorter, and the key result value of the key corresponds to the key result of the short press.
In the technical scheme of the embodiment, the key result value of the key is determined according to the timing duration of the key, and the key result value of long pressing or short pressing of the key can be effectively distinguished. More interaction parameters can be determined according to different result values, and different interaction functions are realized.
Referring to fig. 5, fig. 5 is a second embodiment of the key-based interaction method of the present invention, based on the first embodiment, after the step S31, the step S30 further includes:
step S34, if the timing duration is greater than or equal to the preset duration, acquiring the number of level data bits of the state value of the effective level corresponding to the state value;
step S35, if the number is one, performing the step of assigning the result value corresponding to the long press to the key result value;
and step S36, if the number is at least two, assigning the corresponding result value of the combination to the key result value.
Specifically, when the timing duration is greater than or equal to the preset timing duration, the key corresponding to the timing duration is pressed for a long time, and the number of keys whose state values correspond to the effective level in the level data bit needs to be obtained. When the number of the keys is one, the corresponding key result is long pressing. When the key result is multiple, the key result is a combined press, which indicates that other keys are pressed within the timed time length. After determining the result, the timer period needs to be cleared.
In the technical solution of this embodiment, the key result value of the key is determined according to the number of keys of the active level, and the key result values of long pressing or combined pressing of the keys can be effectively distinguished. More interaction parameters can be determined according to different result values, and different interaction functions are realized.
Referring to fig. 6, fig. 6 is a second embodiment of the key-based interaction method of the present invention, based on the first embodiment, after the step S31, the step S30 further includes:
step S37, if the timing duration is less than the preset duration, acquiring the number of keys corresponding to the level data bit of the effective level corresponding to the state value;
step S38, if the number is one, performing the step of assigning the result value corresponding to the short press to the key result value;
and step S39, if the number is at least two, assigning a result value corresponding to the invalid key to the key result value, and clearing the timing duration.
Specifically, when the timing duration is shorter than the preset duration, the number of keys with the middle state value corresponding to the effective level is obtained, and if the number of the keys is one, the key result is determined to be a short key. And when the number of the keys is at least two, determining that the keys are invalid keys, assigning a result value corresponding to the invalid key to a key result value, and clearing the timing duration.
In the technical solution of this embodiment, the key result value of the key is determined according to the number of keys of the active level, and the short pressing of the key or the invalid key result value can be effectively distinguished. Different interaction parameters may be determined based on different result values.
