Abstract
The invention comprises five buttons including a play button and a + button.
Description
Technical field
The present invention relates on a kind of mobile phone to realize controlling the method for multimedia function with earphone.
Background technology
The use of current phone has reached the degree of popularizing, and the function on the mobile phone is also all the more abundant.Multimedia handset has become the main flow of selling in the market.Polygamy has " line traffic control " earphone on multimedia handset.But " line traffic control " earphone that general multimedia handset is furnished with has only 1 button, and function is very single: only have the function of using this button to connect phone and hang up the telephone in incoming call and communication process.But present multimedia handset generally all has the voice playing function, plays as MP3, and video playback capability is play as MP4; Or other multimedia function, as Kara OK function, language repeater function, FM function, or the like.These multimedia functions all have unified characteristic: support the operation of mobile phone key, carry out function and switch.As when playing MP3,, can go up a first song, next song by the special mobile phone button, volume increases and decreases and the function of time-out/continuation.But present line control earphone has only 1 button, can't use earphone to control these functions at all.
Summary of the invention
In sum, how to overcome the defective of existing multimedia handset, realize using multimedia line control earphone can control the multimedia controlled function easily, this is a technical problem to be solved by this invention, for this reason, the object of the present invention is to provide a kind of method that on mobile phone, realizes multimedia line control earphone function.
Technical scheme of the present invention is as follows:
According to the method that realizes multimedia line control earphone function on a kind of mobile phone of the present invention, at first use multimedia line control earphone to carry out button operation, then, produce interruption by the hardware interrupts interface, at last, software enters the interrupt handling routine of handling the multimedia earphone keystroke.
The interrupt handling routine of described multimedia earphone keystroke is judged and preserved the earphone keystroke state: button is pressed or is released.
When button was carried out push, ADC (simulating a digital translation) module became digital signal to store the voltage transitions that operated respective keys produced of multimedia earphone.
Judge that ADC value judgement after the key assignments handling procedure is according to conversion is which button is pressed or discharges, judge the time length of pressing simultaneously, then with key-press status (press, discharge or press for a long time) and by these message of key send, keep supplying the layer multimedia program and use.
Positive progressive effect of the present invention is: can realize the function of multimedia line control earphone easily by this method on mobile phone, thereby reach the purpose of using line control earphone control multimedia function.

Embodiment
Provide preferred embodiment of the present invention below, to describe technical scheme of the present invention in detail.
Realize the method for multimedia line control earphone function on a kind of mobile phone, mainly be used on the mobile communication equipment such as mobile phone, use line control earphone to carry out the control of multimedia function.
See also Fig. 1, according to program 100, at first, execution in step 1000 uses multimedia line control earphone to carry out button operation, and step 1001 produces interruption by the hardware interrupts interface, and step 1002 software enters the interrupt handling routine of handling the multimedia earphone keystroke.
See also shown in Figure 2ly, the principle that produces the button hardware interrupts is to be pressed or to discharge according to button, and the level of interrupt source is switching between the high-low level: when button was pressed, interrupt source was low level; When button was released, interrupt source was high level.
See also shown in Figure 3ly, produce different output voltages thereby the resistance value that the principle that produces the button output voltage is a different key to be connected is different.
Interrupt handling routine mainly judges that by the height of interrupt source applied signal voltage button is pressed or is released.Under the initial condition, be the low level that is input as of interrupt source with triggering the conditional definition that interrupts.Under the situation that button is not pressed, the signal of interrupt source input keeps high level always.When certain button is pressed, the input signal of interrupt source becomes low level, triggers to interrupt.Interrupt handling routine judges that a button is pressed, sends the message that button is pressed, and it is the high level that is input as of interrupt source that the down trigger condition is set simultaneously.When button was released, the signal of interrupt source input became high level by low level again, triggered and interrupted.Interrupt handling routine sends the d/d message of button, and will trigger the conditional definition that interrupts again is the low level that is input as of interrupt source.
See also shown in Figure 4ly, the button interrupt handling routine is judged according to the height of the level of button interrupt source and is preserved key-press status (press or discharge).
See also Fig. 5, shown in Figure 6, judge that ADC value judgement after the key assignments handling procedure is according to conversion is which button is pressed or discharges.Because the output voltage that produces during button can not all be the same value of determining at every turn, so the ADC value that each button is pairing after being converted can not be certain value of determining.According to this situation, defined different intervals, which key can judge what press according to the residing different intervals of the value of ADC is.If button is to be pressed, then this starts a clock constantly (the time length of clock can freely define, here be defined as 2 seconds), when clock arrives, whether the state that the clock handling procedure is inquired about this button changes, if state does not change (keeping down state to reach 2 seconds) always, then set key-press status and be " long pressing ".
See also shown in Figure 7ly, upper procedure generally is the program of control multimedia function, according to the above-mentioned message that sends, realizes the control of corresponding multimedia function, as volume increase and decrease, the next item up/the next item down switch, time-out/continuation.
