Caused long-pressing resets, and equipment is caused to be restarted.
The second object of the present invention is to provide a kind of chip, which is able to achieve basic operational functions and anti-error when running
Triggering not only can guarantee single-button single by hitting possessed priority function, but also long-pressing caused by being avoided that because of wearing resets, and causes
Equipment is restarted.
The third object of the present invention is to provide a kind of wearable device, which is able to achieve basic operational functions when running
With anti-error triggering, single-button single not only can guarantee by hitting possessed priority function, but also long-pressing caused by being avoided that because of wearing is multiple
Position, causes equipment to be restarted.
An object of the present invention adopts the following technical scheme that realization:
A kind of false-touch prevention bill key hardware reset method, comprising the following steps:
S1, reset chip, input delay time, setting button 0 and key 1 are expanded；
S2,0 is pressed the button, key 1 is motionless, completes the basic function of device definition；
S3, press the button simultaneously 0 and key 1 remain above the delay time of setting, trigger device reset.
Further, step S2 specifically: press the button 0, key 1 is motionless, and key 0, which exports low level by key, to be believed
Number, key 1 exports high level signal, and it is fixed to complete equipment for the push button signalling that the low level signal that key 0 exports is inputted as equipment
The basic function of justice.
Further, step S3 specifically: at the same press the button 0 and key 1 remain above the delay time of setting, key
0 exports low level signal by key, and key 1 respectively passes through one by transducers output low-level signal, two-way low level signal
A reverser, output two-way high level signal are input to AND gate circuit, and output high level signal is set to delay trigger circuit, triggering
It is standby to reset.
Further, the delay trigger circuit exports a low level square wave and resets for generating a delay time
Signal.
Further, the delay time is greater than 2 seconds.
Further, the sensor is switch-type sensor.
The second object of the present invention adopts the following technical scheme that realization:
A kind of chip, for storing program, described program is for executing above-mentioned false-touch prevention bill key hardware reset side
Method.
The third object of the present invention adopts the following technical scheme that realization:
A kind of wearable device, including key and above-mentioned chip；The key is connect with the chip.
Compared with prior art, the beneficial effects of the present invention are:
The present invention proposes a kind of reliable false-touch prevention bill key long-pressing hardware reset method, not by two key outputs
Work, reset and anti-reset are realized with level signal, and equipment both can guarantee that single-button single is had by hitting in normal wear
Some priority functions, and be avoided that because of long-pressing reset caused by dressing, cause equipment to be restarted.
Detailed description of the invention
Fig. 1 is the electricity of a kind of false-touch prevention bill key hardware reset method provided by the invention, chip and wearable device
Road functional block diagram；
Fig. 2 is the letter of a kind of false-touch prevention bill key hardware reset method provided by the invention, chip and wearable device
Number timing diagram.
Specific embodiment
In the following, being described further in conjunction with attached drawing and specific embodiment to the present invention, it should be noted that not
Under the premise of conflicting, new implementation can be formed between various embodiments described below or between each technical characteristic in any combination
Example.
Referring to Fig. 1, a kind of false-touch prevention bill key hardware reset method, comprising the following steps:
S1, reset chip, input delay time, setting button 0 and key 1 are expanded；
S2,0 is pressed the button, key 1 is motionless, completes the basic function of device definition；
S3, press the button simultaneously 0 and key 1 remain above the delay time of setting, trigger device reset.
Further, step S2 specifically: press the button 0, key 1 is motionless, and key 0, which exports low level by key, to be believed
Number, key 1 exports high level signal, and it is fixed to complete equipment for the push button signalling that the low level signal that key 0 exports is inputted as equipment
The basic function of justice.
Preferably, it is usually to be attached directly to single-chip microcontroller that key 0, which exports low level signal because of matrix press-key by key,
On l/O foot, by there is pull-up resistor in single-chip microcontroller pin, normal condition downlink, alignment is all in high level state.In scanning key
When, so that some pin is exported low level, when having key and this foot is connected, so that it may which the pin of high level is pulled into low electricity
It is flat, illustrate to have and be connected by key pressing.
Further, step S3 specifically: at the same press the button 0 and key 1 remain above the delay time of setting, key
0 exports low level signal by key, and key 1 respectively passes through one by transducers output low-level signal, two-way low level signal
A reverser, output two-way high level signal are input to AND gate circuit, and output high level signal is set to delay trigger circuit, triggering
It is standby to reset.
Preferably, key 1 exports low level signal by lower switch by switch-type sensor, and not by switch, output is high
Level signal.
Further, referring to Fig. 2, delay trigger circuit exports a low level side for generating a delay time
Wave reset signal, so that key resets.
Further, delay time is greater than 2 seconds.
Further, sensor is switch-type sensor.Switch-type sensor exports high level signal or low level letter
Number.When a measured signal reaches some specific threshold value, switch-type sensor correspondingly exports the low of a setting
Level or high level signal.
