Fig. 7 illustrates the schematic flow diagram of the trigger detection methodology of touch key-press according to another embodiment of the invention.
As it is shown in fig. 7, the trigger detection methodology of touch key-press according to another embodiment of the invention, including:
Step 702, each button capacitance initializes.
Step 704, it may be judged whether to sweep time, if so, then performs step 706;Otherwise, return step 704 to continue to judge.Wherein can periodically be scanned, if the cycle is 0.5ms.
Step 706, detection button electric capacity instantaneous value and reference value.
Step 708, it is judged that button electric capacity initial value, whether within normal range, if so, then performs step 710;Otherwise, step 702 is returned.Wherein, normal range can be 500 to 5000.
Step 710, it is judged that button capacitance variation amount, whether more than A, if so, then performs step 714, otherwise, returns step 704 after updating reference value, specifically, reference value=initial value+variable quantity.Wherein, A is setting value, it is possible to be set according to actual accuracy requirements, if A can be 20.This step is primarily to the problem avoiding extraneous factor (such as temperature) to affect and to cause button capacitance to change and cause erroneous judgement.
Step 712, it is judged that whether all button capacitance variation amounts are all higher than B, if so, then performs step 714;Otherwise, timing variable returns step 704 after resetting.Wherein, the value of B can be set according to the actual requirements, if B can be 200.
Step 714, all button capacitances take average, update reference value.
Step 716, it is judged that certain button capacitance variation amount, whether more than (reference value+trigger value), if so, then performs step 718;Otherwise, timing variable returns step 704 after resetting.Wherein, trigger value is set also dependent on actual demand.
Step 718, starts timing, and timing variable adds 1.
Step 720, it is judged that timing time, whether more than the lower limit time, if so, then performs step 722;Otherwise, step 704 is returned.
Step 722, it is judged that timing time, whether less than upper limit time, if so, then performs step 724;Otherwise, after updating reference value, return step 704, specifically, reference value=initial value+variable quantity.
Step 724, button triggered as normal.The operation of the function that subsequent execution is corresponding with button.
Specifically, as shown in Figure 8, wherein, for ease of distinguishing, the reference value after updating in the step 710 shown in Fig. 7 being designated as first reference value, the reference value after updating in the step 714 shown in Fig. 7 is designated as the second reference value.Wherein, during initialization, instantaneous value and first reference value, the second reference value are equal.
Assuming that " Y " key triggers, " X " key does not trigger, and assume the B shown in Fig. 7 be 200, trigger value is 80, and assumes that the initial value of button electric capacity is 1000.Then in Fig. 8, (a) show " X " key capacitance over time, and (b) show " Y " key capacitance over time.Wherein curve 802A represents the electric capacity instantaneous value of " X " key, and curve 802B represents the electric capacity instantaneous value of " Y " key, and curve 804 represents first reference value, and curve 806 represents the second reference value.
When " Y " key triggers, all of button capacitance all increases, if the capacitance variation amount of all buttons is all higher than 200, then the capacitance of all buttons is taken average, the second reference value after being updated.
Owing to " Y " key triggers, its deformation is maximum, and capacitance change is also maximum, and when capacitance change exceedes (the second reference value+button trigger value), and the persistent period is between M and S, then button triggered as normal is described.And the electric capacity instantaneous value of " X " key is not reaching to above-mentioned condition, thus without being triggered.
Technical scheme is described in detail above in association with accompanying drawing, the present invention proposes the detection trigger scheme of a kind of new touch key-press, it is capable of reliable button capacitance detecting, improve the accuracy of button detection, it is to avoid cause false triggering owing to the button capacitance of all touch key-presss on touch panel all changes.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, any amendment of making, equivalent replacement, improvement etc., should be included within protection scope of the present invention.
