In example, the configurating channel pin that electronic equipment does not pass through Type-C interface carries out the access detection of external equipment Type-C interface.
Only in the Type-C interface for the Type-C interface access electronic equipment for detecting external equipment, electronic equipment just can be it
The configurating channel pin of Type-C interface provides detection voltage, to identify to external equipment.
In the present embodiment, electronic equipment detects whether external equipment by the default pin of its Type-C interface
Type-C interface accesses the Type-C interface of this electronic equipment.Wherein, this presets pin as non-configurating channel pin, and electronics
Equipment provides the first detection voltage for the default pin.For example, the default pin can be A1, B1, A12, B12 in Fig. 2 and draw
In foot any one, it is two or more.It, can be to one in A1, B1, A12, B12, two that is, in the present embodiment
A or multiple pins are transformed, and so that improved pin is become ungrounded (GND) pin, and improved pin is determined as
Default pin, the default pin can be used for carrying out the access detection of external equipment Type-C interface.For example, it is also possible to will pass through
Improved pin is known as accessing detection pin.In some embodiments, it is very low to can be numerical value for above-mentioned first detection voltage
Voltage, for example, 0.1V or 0.2V etc..
In one embodiment, because using the A1 of the external equipment of (Full Featured) Type-C interface of standard,
A12, B1, B12 are ground connection (GND) pin.Therefore, as the Type-C of the Type-C interface access electronic equipment of the external equipment
When interface, the voltage of the default pin of the Type-C interface of electronic equipment can be pulled low and (be become zero by the first detection voltage), from
And detect the access of the external equipment using Type-C interface.

These three pins of B1, A12, B12 are in NC state.In this case, when (only A1 pin can be with for the Type-C interface of the external equipment
Ground connection) access electronic equipment provided in this embodiment Type-C interface (such as A1 pin is transformed into default pin) when, by
There is no other pins can grounding pin in the Type-C interface with the electronic equipment in the Type-C interface of the external equipment
Connection, leads to that earth-return circuit can not be formed between the external equipment and the electronic equipment, and then the A1 of the external equipment is caused to draw
Foot can not be by the voltage pull-down of the A1 pin of electronic equipment, therefore electronic equipment will be considered that the Type-C currently without external equipment
Interface access causes electronic equipment not identify to using the external equipment of Type-C interface.
In the 101 of the embodiment of the present application, the instruction for carrying out external equipment identification is used to indicate when receiving from user
When, default pin can be grounded by electronic equipment.For example, default pin is A1 pin, i.e. electronic equipment can be by its Type-C
The A1 pin of interface is grounded.
In 102, when detecting default pin ground connection, trigger signal is generated.
For example, the detection voltage of A1 pin can be by first when the A1 pin of its Type-C interface is grounded by electronic equipment

And for the external equipment of different function (such as using the earphone of Type-C interface and USB flash disk etc.), configurating channel
The resistance value for the pull down resistor that pin is connected is different.Therefore, right when the external equipment of different function accesses electronic equipment
The voltage pull-down degree of the configurating channel pin of electronic equipment is different.Therefore, electronic equipment can pass through its configurating channel
The voltage change of pin, to identify which kind of equipment external equipment is specially.
It is understood that in the present embodiment, it is outer when needing that an only pin in Type-C interface can be grounded
When portion's equipment is identified, user can send to electronic equipment and instruct, i.e., electronic equipment, which can receive, is used to indicate progress
The instruction of external equipment identification.It, can be with when default pin ground connection at this point, default pin can be actively grounded by electronic equipment
It triggers the electronic equipment and provides the second detection voltage for the configurating channel pin of its Type-C interface, to be drawn by the configurating channel
