Embodiment
The present invention is described in further detail with reference to the accompanying drawings and examples.It is understood that this place is retouched
The specific embodiment stated is used only for explaining the present invention, rather than limitation of the invention.It also should be noted that in order to just
Part related to the present invention rather than entire infrastructure are illustrate only in description, accompanying drawing.
Embodiment one
Fig. 1 is a kind of schematic flow sheet of the method for identification self-shooting bar that the embodiment of the present invention one provides, and this method can be with
Performed by the device of identification self-shooting bar, wherein the device can be realized by software and/or hardware, can be as one of mobile terminal
Divide and be built in inside mobile terminal.As shown in figure 1, the implementation process includes：
If step 11, detecting that the earphone interface of mobile terminal is inserted with the headset plug of external equipment, the shifting is controlled
Universal asynchronous receiving-transmitting transmitter UART transmitting terminal serial communication chip into the external equipment sends identity and known in dynamic terminal
Do not invite and ask, and control the receiving terminal of the UART to receive the identity response information that the serial communication chip returns.
In the present embodiment, mobile terminal refers to the electronic product of such as smart mobile phone and tablet personal computer or the like, moves
Dynamic terminal has Self-timer, as mobile terminal is provided with front camera.External equipment refers to earphone or wired self-timer
