Fig. 1 describes in detail from terminal equipment side to a kind of anti-interference method of button in the embodiment of the present invention, and this method can be with
Comprise the following steps S101- steps S102.
Step S101：The state of the universal input of detection terminal equipment/output GPIO interface is in the mesh of low level state
Between timestamp.
Specifically, the physical button of terminal device is connected by the GPIO interface with the CPU of terminal device, wherein, when
The state of GPIO interface is in high level state when physical button is not pressed, the shape of GPIO interface when physical button is pressed
State is in low level state.Terminal device (specific functional modules or CPU in such as terminal device are in itself) continues detection terminal and set
The operating time that standby physical button is pressed, the i.e. state of the GPIO interface of detection terminal equipment are in the target of low level state
Time.It is appreciated that the object time refers to that the state of GPIO interface is continuously in the time of low level state, rather than
Every the time of accumulation, if centre returns to high level state or other states, the object time resets, recalculated.Further
Ground, the physical button in various embodiments of the present invention can be the button with unlocked by fingerprint function.
It should be noted that it is to need (to press) by button because GPIO interface level state drags down (low level state)
Drag down, and it is that the processing inside CPU acts to draw high (high level state), therefore the low level shape by high level state to after dragging down
State will not be interfered (because must have the action pressed), and can be then interfered by low level state to high level state
(can be that electrostatic leads to not return to high level state), therefore, be only possible to by electrostatic after user pushes button
Deng interference, and button will not be disturbed by electrostatic etc. before user does not push button, therefore how the main discussion of the present invention solves
Certainly after user pushes button, button starts the interference being subject to, i.e. GPIO Interface status can not normally return to from low level
The problem of high level state.
Step S102：When the object time exceeding preset time threshold, drawing high the level of the GPIO interface makes institute
The state for stating GPIO interface is at the appointed time in high level state in section.
Specifically, when detecting that the object time exceedes preset time threshold (such as 5s), then it is judged as that the physical button is worked as
Before there may be interference such as electrostatic interference, now, the physical button or other functions that may result in terminal device can not be just
Often use, and the level for drawing high the GPIO interface makes the state of the GPIO interface at the appointed time be in high level state in section,
Equivalent to indirectly GPIO interface is restarted or reset, then now, GPIO interface recovers normal operating conditions again, you can with
Physical button is avoided to cause the seemingly-dead situation of GPIO interface due to interference such as electrostatic.Wherein, the electricity of GPIO interface is specifically drawn high
Quadratic method is prior art, be will not be repeated here.
The embodiment of the present invention, low level is in by the state of universal input/output GPIO interface of detection terminal equipment
The object time of state, when the object time exceeding preset time threshold, drawing high the level of GPIO interface makes the shape of GPIO interface
State is at the appointed time in high level state in section.The GPIO that scheme i.e. provided in an embodiment of the present invention passes through detection terminal equipment
The state of interface is in whether low level state exceedes certain time length, when more than certain time length, is then judged as the physical button
Interference (such as electrostatic interference) is may currently exist, now, by forcing to draw high the level of GPIO interface, and then shorter
GPIO is reset in time, so as to eliminate due to logic error caused by electrostatic interference, solves physics in the prior art
Button may due to caused by interference can not normal use the problem of, improve Consumer's Experience.
Fig. 2 is the schematic flow sheet of the anti-interference method of another button provided in an embodiment of the present invention, below in conjunction with
Accompanying drawing 2 describes in detail from terminal equipment side to the anti-interference method of another button in the embodiment of the present invention, this method
It may comprise steps of S201- steps S206.
Step S201：The state of the universal input of detection terminal equipment/output GPIO interface is in the mesh of low level state
Between timestamp.
Step S202：When the object time exceeding preset time threshold, drawing high the level of the GPIO interface makes institute
The state for stating GPIO interface is at the appointed time in high level state in section.
Specifically, step S201 to step S202 refers to the step S101 to step S102 in above-mentioned Fig. 1 embodiments, this
In repeat no more.
Step S203：Delay when default, detect the state of the GPIO interface of the terminal device.
Specifically, the level of the GPIO interface is drawn high in step S202 makes the state of the GPIO interface when specified
Between be in high level state in section after, delay when default, detect the state of the GPIO interface of the terminal device.Forcing
After drawing high the default time delay (such as 200ms) after GPIO interface level, just go to detect the current state of GPIO interface, allow GPIO to connect
Mouth state has the regular hour to return to normal condition, avoids in (restarting process) in the short time for drawing high GPIO interface level
Non-genuine state reporting to CPU, cause to judge by accident.
In a kind of possible implementation, stop reporting the terminal to set to the CPU in the specified time section
The state of standby GPIO interface.Specifically, because terminal device in the prior art periodically can report the GPIO to connect to CPU
The state of mouth, now is forced to draw high (high level state) because in the specified time section, the state of GPIO interface is in,
Therefore the time of day of physical button is not represented, for example, when button is pressed 10s by user, i.e. truth is in the 10s
The state of GPIO interface is low level state, if but start pressure in 5s and draw high GPIO, and by the state of GPIO interface
CPU is reported, then can report truth by mistake, allows CPU to take for now physical button and unclamps (not being pressed), and substantially now
Physical button is the state being pressed always, and the system for ultimately resulting in terminal device produces logic error.Therefore, the present invention is implemented
In the scheme that example provides, in the specified time section that this is drawn high, the level state of GPIO interface is not reported to CPU, and when drawing
Height action reports to CPU again after completing, and avoids judging by accident.
Step S204：When the state for detecting the GPIO interface is in high level state, reported to the CPU described
Physical button is not pressed.
Specifically, when the state for detecting GPIO interface is in high level state, then show physical button really
It is released, i.e., reports physical button not to be pressed to CPU.
Step S205：When the state for detecting the GPIO interface is in high level state, physics described in user is prompted
Button there is currently interference.
Specifically, the level of the GPIO interface is drawn high in step S202 makes the state of the GPIO interface when specified
Between be in high level state in section after, delay when default, detect the state of the GPIO interface of the terminal device, when detecting
When the state of the GPIO interface is in high level state, physical button described in user is prompted to there is currently interference.Because force
After drawing high the level of GPIO interface, if the state still high level state that GPIO interface is current, can be shown that the object time
The reason for more than predetermined threshold value is not that user presses physical button and exceedes preset time threshold, but presses physical button in user
Afterwards, physical button receives interference (such as electrostatic interference), just causes to force to draw high in the very short time after GPIO interface,
The state of GPIO interface has been then restored to normal high level state, it is therefore desirable to makes prompting, present physical button to user
Interference be there may be, it is necessary to which user carries out some adjustment.It should be noted that without execution between this step S205 and step S204
Precedence relationship, you can with step S204 simultaneously perform can also be performed before or after step S204, the present invention to this not
Make specific limit.
Step S206：When the state for detecting the GPIO interface is in low level state, reported to the CPU described
Physical button is pressed.
Specifically, when the state for detecting GPIO interface is in low level state, then possible user is represented in fact always
Physical button is being pressed, or physical button is pressed again in of short duration release, i.e., is reporting the physical button to CPU
It is pressed.
The embodiment of the present invention, low level is in by the state of universal input/output GPIO interface of detection terminal equipment
The object time of state, when the object time exceeding preset time threshold, drawing high the level of GPIO interface makes the shape of GPIO interface
State is at the appointed time in high level state in section.The GPIO that scheme i.e. provided in an embodiment of the present invention passes through detection terminal equipment
The state of interface is in whether low level state exceedes certain time length, when more than certain time length, is then judged as the physical button
Interference (such as electrostatic interference) is may currently exist, now, by forcing to draw high the level of GPIO interface, and then shorter
GPIO is reset in time, so as to eliminate due to logic error caused by electrostatic interference, solves physics in the prior art
Button may due to caused by interference can not normal use the problem of, improve Consumer's Experience.
