Embodiment one

The embodiment of the present invention provides a kind of method of interface configuration combined with Figure 1 and Figure 2, for working as the plug of interface arrangement While being inserted into socket, the Y-track either interface of data line is inserted into an access device.Identification insertion equipment be USB or When being MHL, for convenience, referring to Fig. 3, the embodiment of the present invention is using the face A as the first inserting surface, using the face B as the second insertion It is illustrated for face.As shown in figure 4, the method may include:

S101, when access device access, the energization pins of any inserting surface are sent to the power-supply controller of electric of terminal device Access signal.

It should be noted that when the Y-track first interface of the first access device insertion data line, the corresponding A of socket The pin of face 1 sends access signal to the power-supply controller of electric of terminal device.

After receiving the access signal that No. 1 pin in the face A is sent to power-supply controller of electric, the power-supply controller of electric of terminal device is examined The access of the first access device is measured, sends interrupt requests to CPU.

S102, indicate that pin receives the piece connecting with the socket according to the access device type of any inserting surface The signal condition that controller is forwarded is selected, identifies the device type of the access device, determines the work of any inserting surface State.

Specifically, the signal that the access device type instruction pin of any inserting surface selects controller to forward with piece connects It is logical.

The CPU of terminal device sends bind command to MHL chip controller, selects controller to connect the control of MHL chip by piece No. 4 pins of order the transmission signal and the face A of device processed.

Since terminal device is by No. 4 pins, i.e. the CBUS signal wire of the ID of USB or MHL identifies access device, because This, selects that controller connects the order transmission signal of MHL chip controller and No. 4 pins in the face A judge access device by piece Type.

No. 4 pins in the face A are hanging according to the order of MHL chip controller transmission signal condition or voltage is pulled low, The working condition for judging the face A is USB working condition or MHL working condition.

Specifically, when any inserting surface of only the first access device insertion, and any inserting surface is the first insertion When face, referring to Fig. 5, step S102 includes step S1021 to S1024:

S1021, it is selected described in controller receives by piece when the access device type instruction pin of first inserting surface The order transmission signal condition of MHL chip controller is hanging, and first access device is identified as USB device, and described first inserts Enter face into the first USB working condition.

Under default conditions, No. 4 pin CBUS/USB_ID have pull-up resistor, and USB_ID foot keeps high level, USB switch The side USB is got to high-speed switches, MHL is disconnected at this time.

When the USB port of the face A connection apparatus such as computer, No. 4 pin connection status and level height in the face A are determined.

Since the pin contacts of apparatus such as computer USB port are 4, i.e. 4pin, when first access device in the face A connects USB When mouth, 4 signal wires of 5 signal wires connection USB port in the face A, at this point, the 4th foot CBUS/USB_ID in the face A is hanging.So A No. 4 pins in face still keep high level, then the face A enters the first USB working condition.

What needs to be explained here is that the first USB working condition indicates the terminal device in the connection face A as USB device (USB- DEVICE it) uses.

S1022, it is selected described in controller receives by piece when the access device type instruction pin of first inserting surface The order transmission signal condition voltage of MHL chip controller is pulled low, and the pull down resistor of the order transmission signal is 1K When Ω, if confirmation first access device is MHL equipment, first inserting surface enters MHL working condition.

When the face A connects MHL equipment, the order transmission signal voltage of MHL chip controller can be pulled low.If order transmission The pull down resistor of signal is 1K Ω, opens handshake procedure, confirms whether the first access device is MHL equipment by handshake procedure.

If the first access device is MHL equipment, piece selects controller to continue to connect the order transmission letter of MHL chip controller Connection status is changed to MHL state by No. 4 pins number with the face A, USB switch, and the face A enters MHL working condition.It receives Described is selected controller to forward.

S1023, it is selected described in controller receives by piece when the access device type instruction pin of first inserting surface The order transmission signal condition voltage of MHL chip controller is pulled low, and the pull down resistor of the order transmission signal is 1K When Ω, if confirmation first access device is not MHL equipment, equipment recognition failures.
