S406, judges whether described base-line data value is all more than or equal to described second predetermined threshold value in the first preset duration; If described base-line data value is all more than or equal to described second predetermined threshold value in the first preset duration, then perform step S404; Otherwise do not do any process.
Wherein, described second predetermined threshold value is greater than described first predetermined threshold value.
The possible cause not responding touch operation due to touch-screen comprises two large classes, and a class is that touch-screen self does not respond, and cannot provide look-at-me to processor, and another kind of is that touch-screen normally have issued look-at-me to processor, but processor end does not respond.Therefore, eliminated due to after touch-screen self reason causes not responding the possibility of touch operation by step S401-S406, can also step S407-S409 be performed, the problem causing touch-screen not respond with the reason got rid of because of processor.
S407, reads the level of interrupt pin corresponding to described touch-screen;
S408, judges whether the level of described interrupt pin is low level in the second preset duration;
S409, if described interrupt pin is low level in the second preset duration, then discharges described interrupt pin, and again applies for described interrupt pin.
Under normal circumstances, touch-screen interrupt pin is high level, in time having touch event to occur, interrupt pin will be dragged down, if now the processor of intelligent terminal reads the data register of touch-screen, this interrupt pin just will be driven high, for touch event next time.If processor does not read the data register of touch-screen, this interrupt pin just will be in low level state always, and such touch-screen just responds follow-up touch operation never, thus causes the global failure of touch-screen.Therefore, by reading the interrupt pin low and high level signal of touch-screen, in the second preset duration, if continuous print low level, illustrating that AP holds interrupt processing to occur problem, no longer responding the touch of touch-screen.So discharge this interrupt pin, and then again apply for this touch-screen interrupt pin, thus complete reset.
It should be noted that, step S407-S409 and step S401-S406 can independently carry out, also step S407-S409 is performed after can first performing step S401-S406, step S401-S406 is performed after can also first performing step S407-S409, thus guarantee the problem that omnibearing solution touch-screen does not respond, realize detecting touch-screen easily and fast and repairing.
