Abstract
A method for multiplexing line-controlled button of handheld information device features that when the CPU of said handheld information device receives the buttom interrupt signal and A/D converted signal from line-controlled earphone, the time when the button is pressed is analyzed and the multiplex function of the button is determined and generated. As a result, the button of line-controlled earphone can be used to control the screen switch of device.
Description
Technical field:
The present invention relates to a kind of multiplexing method of hand held information equipment wire controlling button, be meant that especially a kind of being used for having motion picture expert group audio layer (MPEG AUDIO LAYER 3, abbreviation MP3) on the personal digital assistant of playing function, utilize wire controlling button to close the method for display screen.
Background technology:
Along with the development of extensive integrated electronic technology, the function of personal digital assistant (Personal DigitalAssistant is called for short PDA) is more and more abundanter.All be provided with MP3 (a kind of audio compression form) playing function on present many PDA, this user for PDA provides the amusement function outside the normal function.
When playing MP3, need not to open again display screen usually; This is extremely important as the PDA of power supply energy-conservation for using battery.For this reason, some apparatus bodies are provided with a button that is used to close or open screen, and the user can utilize this button to operate, and do not appreciate MP3 and do not influence.And screen will be saved electric energy after closing very much.But, button inconvenient operation on the one hand is set on apparatus body, also taken the button resource of preciousness on the equipment on the other hand.
Referring to Fig. 1, generally be used to listen to the line control earphone of MP3 and the connecting circuit of PDA comprises button S1, S2, S3, S4, be respectively applied for the control playback, stop, last one bently selecting, next bent selection.They are connected with resistance R 1, R2, R3, R4 with the resistance that has nothing in common with each other respectively, are parallel-connected to the input end of modulus (AD) converter of PDA main frame then, and this input end also connects a divider resistance R5 simultaneously; When pressing the button S1 or S2 or S3 or S4, be input to AD converter after connected resistance R 1 or R2 or R3 or R4 and resistance R 5 dividing potential drops, and convert the CPU that digital signal sends PDA to through this AD converter; Simultaneously, this voltage division signal produces the look-at-me of CPU after the voltage comparator conversion, is used to control CPU and receives the digital signal of being changed by AD converter.CPU produces function corresponding by this digital signal is analyzed.
Because above-mentioned keypress function is analyzed the back by CPU to button and produced, therefore above-mentioned button can produce by multiplex mode.
Summary of the invention:
Fundamental purpose of the present invention is to provide a kind of multiplexing method of hand held information equipment wire controlling button, by the action button on the multiplexing line control earphone, realizes the switch of opertaing device screen, when realizing power saving, helps the operation of switch screen.
The object of the present invention is achieved like this:
A kind of multiplexing method of hand held information equipment wire controlling button, the CPU of hand held information equipment receives from the button look-at-me of line control earphone and analog to digital conversion signal and according to this signal and produces corresponding button control function, this CPU is when receiving button look-at-me and analog to digital conversion signal, earlier the button time is analyzed, determined and produce the multiplexing function of this button then.
The concrete steps that CPU produces the multiplexing function of button are:
Step 1:CPU picks up counting after receiving the button look-at-me;
Step 2: start analog to digital conversion, read magnitude of voltage by the wire controlling button input;
Step 3: the time that time-delay one is set, start analog to digital conversion, read magnitude of voltage by the wire controlling button input;
Step 4: with sampled value comparison last time;
Step 5: if voltage difference not in the scope of setting, execution in step 8;
Step 6: if timing reaches the time of setting, execution in step 9;
Step 7: execution in step 3;
Step 8: produce the first predetermined function of this button, finish;
Step 9: produce second function of this button, finish.
Described line control earphone is provided with more than one button at least, and each button is parallel-connected to the analog to digital converter of PDA main frame and the input end of voltage comparator respectively with after resistance is connected; The resistance of this resistance has nothing in common with each other; This input end also connects a divider resistance simultaneously.
Described first function is the MP3 playback or stops or next bent or last song.
Described second function is start or shutdown or pass screen or spreads its tail.
The present invention is by the action button on the multiplexing line control earphone, realized being used in the operation of the switch of line control earphone button control device screen, when realizing power saving, made things convenient for the switch screen.
Description of drawings:
Fig. 1 is the principle schematic that earphone line traffic control switch is connected with PDA.
Fig. 2 is the process flow diagram of one embodiment of the invention.
Embodiment:
The present invention is described in further detail below in conjunction with accompanying drawing and specific embodiment:
Referring to Fig. 1, the line control earphone that present embodiment adopts comprises button S1, S2, S3, S4, is respectively applied for the control playback, stops, last one bently selecting, next bent selection.They are connected with resistance R 1, R2, R3, R4 with the resistance that has nothing in common with each other respectively, are parallel-connected to the input end of the AD converter of PDA main frame then, and this input end also connects a divider resistance R5 simultaneously; When pressing the button S1 or S2 or S3 or S4, be input to AD converter after connected resistance R 1 or R2 or R3 or R4 and resistance R 5 dividing potential drops, and convert the CPU that digital signal sends PDA to through this AD converter; Simultaneously, this voltage division signal produces the look-at-me of CPU after the voltage comparator conversion, is used to control CPU and receives the digital signal of being changed by AD converter.CPU produces function corresponding by this digital signal is analyzed.
Referring to Fig. 1, in order to realize adopting this line control earphone to control spreading its tail of PDA simultaneously or close screen, can define button S1, S2, S3, S4 on the basis of former function, have start, shutdown simultaneously, close second function such as shield, spread its tail.Concrete implementation method comprises the steps: at least
Step 1:CPU picks up counting after receiving the button look-at-me;
Step 2: start analog to digital conversion, read magnitude of voltage by the wire controlling button input;
Step 3: the time that time-delay one is set, start analog to digital conversion, read magnitude of voltage by the wire controlling button input;
Step 4: with sampled value comparison last time;
Step 5: if voltage difference not in the scope of setting, execution in step 8;
