Detailed Description
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
The control method disclosed by the embodiment of the application is a control method for a connecting device comprising at least two communication channels, and a main body for implementing the control method can be integrated in the connecting device, and can control communication interaction between two electronic devices based on the condition of the connected electronic devices after different electronic devices are connected at two ends of the connecting device. The control method of the embodiment of the application can enable the two electronic devices connected at the two ends of the connecting device to be in a master device-master device connecting mode or a master device-slave device connecting mode. In different connection modes, the range of functions that can be achieved by the two connected electronic devices is different.
The connection means may be independent, for example, an independent connection cable; or integrated in some electronic device, one end is directly connected with the processing system of the electronic device, and the other end is exposed and presented in the form of an interface for connecting other electronic devices. The product form of the electronic device is not limited to the electronic device integrated with the connecting device, and may include, but is not limited to, a smart phone, a tablet computer, a wearable device, a Personal Computer (PC), a netbook, and the like, and may be selected according to application requirements.
Fig. 1 is a flowchart of a control method according to an embodiment of the present application. Referring to fig. 1, the control method may include:
step 101: after the first electronic device and the second electronic device are connected, attribute information of the first electronic device and/or the second electronic device is obtained at least through at least one of the first interface and the second interface.
In one implementation, the first electronic device and the second electronic device may establish a connection through a connection cable that exists independently. The connection may be established by connecting one end of the connection cable to an electronic device before connecting the other end of the connection cable to the electronic device, and then establishing connection between the first electronic device and the second electronic device. Alternatively, both ends of the connection cable may be connected to the electronic device simultaneously or in a short time.
The first interface and the second interface can be the same type of interface or different types of interface. For example, the first interface may be a USBType-a (hereinafter abbreviated as a-port) interface, and the second interface may be a USBType-C (hereinafter abbreviated as C-port) interface; or, the first interface and the second interface are both USBType-C interfaces.
When the first interface and the second interface are the port a and the port C, the port a is generally only used for connecting a host device, such as a desktop computer, a notebook computer, etc., so if the first interface of the connection cable is already connected with the first electronic device, the attribute information of the first electronic device can be directly determined as the host device without obtaining the attribute information of the first electronic device; and after the second electronic equipment is connected to the C port, the attribute information of the second electronic equipment can be obtained, and then the connection mode between the first electronic equipment and the second electronic equipment can be determined. If the second electronic device is connected before the connection cable is connected to the port C, attribute information of the second electronic device is obtained when the connection cable is connected to the port C, so that when the first electronic device is connected to the port a, the first electronic device connected to the port a is defaulted to be the main device, and the attribute information of the first electronic device is not required to be obtained.
If both ends of the connection cable are connected to the electronic device backward at the same time or in a short time, it may be determined whether to obtain attribute information of the connected electronic device based on the types of the first interface and the second interface. If the interface type is the A port, the electronic equipment connected with the interface type is defaulted as the main equipment, and if the interface type is the C port, the attribute information of the electronic equipment connected with the C port is required to be obtained.
In another implementation, a connection device (connection cable) for connecting two electronic devices may be integrated in the electronic device, corresponding to an end of the connection cable fixedly connected to the electronic device into which it is integrated. Specifically, for example, a connection cable can be used between the interfaces of the motherboard and the surface of the housing, and after the interfaces are adapted to a common cable or wireless access, different communication channels are established between the motherboard and the interface of the housing based on attribute information of the connected electronic device.
Wherein the attribute information may include, but is not limited to, device type, device identification, device configuration, etc. In some cases, the connection role of the electronic device can be directly determined according to the attribute information, for example, when the attribute information indicates that the electronic device is a mobile hard disk, a docking station or the like, the electronic device can be determined to be a slave device; when the attribute information indicates that the electronic device is a device such as a mobile phone or a PAD, the electronic device can be determined to be a master device or a slave device based on a preset policy or a processing rule.
Step 102: and controlling the first electronic equipment and the second electronic equipment to establish a first communication channel or a second communication channel based on the attribute information.
If the attribute information indicates that the first electronic device or the second electronic device is a mobile hard disk type device, the mobile hard disk type device can be directly determined to be a slave device, and the connection mode between the first electronic device and the second electronic device is the master device-slave device connection mode, so that communication between the first electronic device and the second electronic device can be realized through a transparent communication channel. If the attribute information indicates that the first electronic device and/or the second electronic device is an electronic device such as a mobile phone, which can be used as a master device or a slave device, the connection mode between the first electronic device and the second electronic device can be determined to be a master device-master device mode or a master device-slave device mode by further combining other information. Other information that may be combined with determining the connection mode may be implemented in various ways, such as any one or more of device operation information, device power information, device communication connection status, and user selection.
In the embodiment of the application, the connection mode of the master device and the slave device can be communicated based on the first communication channel, and the connection mode of the master device and the slave device can be communicated based on the second communication channel. The first interface and the second interface are respectively positioned at two opposite ends of the first communication channel or the second communication channel, and the transmission parameters of the first electronic device and the second electronic device under the first communication channel are different from the transmission parameters under the second communication channel. The transmission parameters may be, but are not limited to, transmission bandwidth, transmission direction, access rights, whether power can be transmitted, and the like.
According to the control method, a proper communication channel can be determined from different communication channels according to the attribute information of the connected electronic equipment, interaction between the two electronic equipment is realized based on the determined communication channel, and the real use will of a user can be better attached, so that different use requirements of the user are met.
The obtaining, by at least one of the first interface and the second interface, attribute information of the first electronic device and/or the second electronic device in the foregoing embodiments may include: and under the condition that the first electronic equipment and the second electronic equipment are connected through a first connecting device, acquiring attribute information of the first electronic equipment and/or the second electronic equipment based on connection information between the first connecting device and the first electronic equipment and/or the second electronic equipment. The connection information may include a connection interface type, whether to connect, connection timing, and the like.
In this implementation, the first connection device may be an intelligent cable, and a CCLogic chip, that is, a CC logic control chip, may be integrated in the cable, or may be another chip capable of implementing CC logic control, such as a PD chip. FIG. 2 is a schematic diagram of a logic architecture of a smart cable according to an embodiment of the present application, wherein the smart cable is denoted by smartcable. Referring to fig. 2, in addition to the above CCLogic chip or PD chip, the smart cable further includes a hosttohost bridge module, that is, a conversion circuit for implementing data transmission in a master-master connection mode, on the first communication channel; the second communication channel, hosttodevicechannel, on the first communication channel is the communication channel in the master-slave connection mode. The first communication channel and the second communication channel are parallel, two ends of the first communication channel and the second communication channel are respectively connected to one switch, the CCLIC chip or the PD chip receives attribute information from a CC pin of the C port, and based on the attribute information, whether the electronic equipment connected with the C port is a master equipment or a slave equipment is determined, and then the two switches are controlled to be connected with the corresponding communication channels. In fig. 2, port a of the intelligent cable is connected to the main device. In other examples, both interfaces of the intelligent cable may be C-ports, and the CCLogic chip or the PD chip may obtain attribute information of the first electronic device and the second electronic device at the same time or backward.
In the foregoing, the obtaining, based on the connection information between the first connection apparatus and the first electronic device and/or the second electronic device, attribute information of the first electronic device and/or the second electronic device may include: and the connection information characterizes that the first connection device is in first connection with the first electronic equipment through a first interface, and second attribute information of the second electronic equipment is acquired through the second interface.
For example, if the first interface of the first connection apparatus is the a port, which is already in the typeA connection state with the first electronic device, it may be determined that the first electronic device is the master device, so that it is necessary to obtain second attribute information of the second electronic device through the second interface (C port), and determine that the first electronic device is the master device or the slave device based on the attribute information of the second electronic device, thereby controlling to switch on the first communication path or the second communication path.
Or, the obtaining, based on the connection information between the first connection apparatus and the first electronic device and/or the second electronic device, attribute information of the first electronic device and/or the second electronic device may include: and establishing a first connection between the first connecting device and the first electronic equipment through a first interface, establishing a second connection between the first connecting device and the second electronic equipment through a second interface, and acquiring second attribute information of the second electronic equipment through the second interface.
For example, the first interface of the first connection device is an a port, the second interface is a C port, the connection information characterizes that the first connection device establishes a typeA connection with the first electronic device through the a port, and establishes a typeC connection with the second electronic device through the C port.
Or, the obtaining, based on the connection information between the first connection apparatus and the first electronic device and/or the second electronic device, attribute information of the first electronic device and/or the second electronic device may include: and the connection information characterizes that the first connection device is in second connection with the first electronic equipment through a first interface, and second attribute information of the second electronic equipment is acquired through the second interface.
For example, the first interface of the first connection device is a port C, which is in a typeC connection state with the first electronic device before, and the first attribute information of the first electronic device is obtained; the second interface is also a C-port, so that second attribute information of the second electronic device needs to be further obtained through the second interface, and then the attribute information of the first electronic device and the second electronic device is combined, and even other information can be referred to determine whether the first electronic device and the second electronic device are master devices or slave devices.
Or, the obtaining, based on the connection information between the first connection apparatus and the first electronic device and/or the second electronic device, attribute information of the first electronic device and/or the second electronic device may include: and establishing a second connection between the first connecting device and the first electronic equipment through a first interface, establishing a second connection between the first connecting device and the second electronic equipment through a second interface, acquiring first attribute information of the first electronic equipment through the first interface, and acquiring second attribute information of the second electronic equipment through the second interface.
For example, the first interface of the first connection device is a C-port, the second interface is also a C-port, the connection information characterizes that the first connection device establishes a typeC connection with the first electronic device through the first interface, and establishes a typeC connection with the second electronic device through the second interface, and at this time, the device types of the first electronic device and the second electronic device cannot be determined, so that the attribute information of both the two electronic devices needs to be obtained, and the first attribute information and the second attribute information are combined, and even other information is combined to determine whether the first electronic device and the second electronic device are master devices or slave devices.
In another implementation, the obtaining, at least through at least one of the first interface and the second interface, attribute information of the first electronic device and/or the second electronic device may include: and under the condition that the first electronic equipment and the second electronic equipment establish the connection through a second connection device, acquiring first attribute information of the first electronic equipment through the first interface or acquiring second attribute information of the second electronic equipment through the second interface.
For example, the second connection device may be integrated or fixedly connected in the first electronic device or the second electronic device, and the second connection device itself is already connected to the motherboard of the electronic device integrated with the second connection device, so that only attribute information of other connected electronic devices needs to be obtained. When the second connecting device is integrated in the first electronic equipment, second attribute information of the second electronic equipment can be obtained through the second interface; when the second connection device is integrated in the second electronic device, the first attribute information of the first electronic device can be obtained through the first interface.
The foregoing details the different implementations and scenario applications of obtaining attribute information of the first electronic device and/or the second electronic device through at least one of the first interface and the second interface, which are helpful for those skilled in the art to better understand and implement the solution of the present application.
Fig. 3 is a schematic logic diagram of an interface identification device type according to an embodiment of the present application. As shown in fig. 3, in the foregoing embodiment, obtaining attribute information of the first electronic device and/or the second electronic device may include: and obtaining the attribute information through the voltage change of the power line pins of the first interface and/or the second interface.
The power line, i.e. VBUS, the VBUS signal can reflect the voltage change, i.e. the VBUS signal can help to determine whether the device accessed by the interface is a master device or a slave device. After the interface is connected with the electronic device, if the VBUS signal reflects that the voltage on the power line pin is raised to a certain value, the electronic device representing the interface connection can be at least used as a main device, and if the voltage on the power line pin of the interface is raised after the interface is connected with the desktop, the connected device (desktop) is determined to be the main device. In one example, a USB switch (USBSW) is turned on by default through a USB port voltage identification device, and after a USB device (slave device) is connected, the USB switch is directly connected to a USB port of a PCH (south bridge) of a host side and then connected to the host device, when an interface connected to the host side detects that VBUS has voltage access, it is determined that an electronic device connected to the interface having voltage access is the host device, and an electronic device connected to the other end interface is the slave device.
In another implementation, the obtaining attribute information of the first electronic device and/or the second electronic device may include: and obtaining the attribute information through the communication signal impedance change of the first interface and/or the second interface.
Wherein, the impedance change of the communication signal can be the impedance change between the USB power supply and the signal. In one example, the access device is detected through the USB signal impedance, and when the USB device (slave device) is connected to the interface, it is detected that the impedance between the USB power module and the signal (d+/D-) changes, and then it is determined as the slave device, and the power module and the USB switch are turned on, so that transparent transmission of USB data between the first electronic device and the second electronic device is realized.
In other implementations, the attribute information may be obtained by combining the two implementations, so that the basis for determining the master device and the slave device is more, the determined result is more accurate, and the real cluster of users is met. The obtaining attribute information of the first electronic device and/or the second electronic device may include: and obtaining the attribute information through the communication signal impedance change and the power line signal change of the first interface and/or the second interface.
In yet another implementation, the obtaining attribute information of the first electronic device and/or the second electronic device may include: and reading attribute information of the first electronic equipment and/or the second electronic equipment through a data transmission channel between the first interface and/or the second interface.
That is, the first interface and the second interface are provided with data transmission channels connected with the control chip, for example, the control chip is connected with the CC pins of the first interface and the second interface, so that the CC channels between the control chip and the interfaces are formed. The interface-connected electronic device can send its attribute information through the CC channel, so that the control chip can correctly identify the device type of the connected device.
The foregoing describes several implementations of the attribute information of the electronic device obtained through the interface, which is convenient for those skilled in the art to better implement the scheme of the present application, but does not constitute a fixed limitation on the obtaining of the attribute information of the electronic device by the present application.
Fig. 4 is a flowchart for controlling establishment of a communication channel between electronic devices according to an embodiment of the present application. Referring to fig. 4, in the foregoing embodiment, controlling, based on the attribute information, establishment of a first communication channel or a second communication channel between the first electronic device and the second electronic device may include:
Step 401: determining a configuration relation between the first electronic device and the second electronic device based on the attribute information, wherein the configuration relation at least comprises an access mode between the first electronic device and the second electronic device, and the method proceeds to step 402 and/or step 403.
The configuration relation between the first electronic device and the second electronic device corresponds to the connection mode, and when the configuration relation corresponds to the master device-master device connection mode, the first electronic device can access the second electronic device, and the second electronic device can also access the first electronic device. When the configuration relation corresponds to a master-slave connection mode, if the first electronic device is the master device and the second electronic device is the slave device, the first electronic device can access the second electronic device, and the second electronic device cannot access the first electronic device; if the first electronic device is a slave device and the second electronic device is a master device, the second electronic device can access the first electronic device, and the first electronic device cannot access the second electronic device.
Of course, in different implementations, the configuration relationship may also include other content, for example, may include data bandwidth, power supply parameters, and the like. It can be understood that in the case that the first electronic device is a master device and the second electronic device is a master device and a slave device, the bandwidth resources of the first electronic device for obtaining data from the second electronic device are different; furthermore, when the second electronic device is acting as a slave device, the first electronic device may charge the second electronic device via the connection means comprising the first interface and the second interface, whereas when the second electronic device is acting as a master device as well, the first electronic device will not be able to charge the second electronic device, which is also the master device.
Step 402: and if the configuration relation characterizes that the first electronic equipment and the second electronic equipment are respectively configured as an access terminal and an accessed terminal, controlling the first electronic equipment and the second electronic equipment to establish a second communication channel.
If the first electronic device is a master device and the second electronic device is a slave device, the first electronic device is an access terminal, and the second electronic device is an accessed terminal. The access terminal and the accessed terminal can communicate through a second communication channel, and the second communication channel can realize transparent transmission of communication data between the first electronic device and the second electronic device or transmission after conversion through a USB converter.
Step 403: and if the configuration relation characterizes that the first electronic equipment and the second electronic equipment are configured as an access terminal and an accessed terminal, controlling the first electronic equipment and the second electronic equipment to establish the first communication channel.
If the first electronic device is the main device and the second electronic device is the main device, the first electronic device is the access terminal and the accessed terminal at the same time, the second electronic device is the access terminal and the accessed terminal at the same time, and the first electronic device and the second electronic device communicate through a first communication channel different from the second communication channel. The second communication channel is provided with a bridge chip, that is, host tohostbridge in fig. 2, for performing conversion of communication data, so as to realize access of the access terminal to the accessed terminal.
The first electronic device and the second electronic device have different access rights under the first communication channel and the second communication channel. The foregoing describes related content, two-way access implemented by a first communication channel, one-way access implemented by a second communication channel. In addition, the power paths of the first electronic device and/or the second electronic device are different under different communication channels. As described above, when an electronic device is used as a slave device, that is, the connection mode is the master device-slave device, the power path may be turned on, and the electronic device as the master device may charge the electronic device as the slave device; and when the two electronic devices are both main devices, the power supply path between the two electronic devices is disconnected by default, and neither electronic device can charge the other electronic device.
In the foregoing, determining the configuration relationship between the first electronic device and the second electronic device based on the attribute information may include: and if the attribute information characterizes that the first electronic device and the second electronic device belong to an uplink port device and a downlink port device respectively, determining that a first configuration relation exists between the first electronic device and the second electronic device, and under the first configuration relation, the first electronic device can access the second electronic device or the second electronic device can access the first electronic device.
In this implementation, one of the first electronic device and the second electronic device belongs to UFP (upstream facility port) devices, such as a usb disk, a mobile hard disk, an input device, and the like, and the other belongs to DFP (downstream facility port) devices, such as a desktop. In this implementation, the downstream port device can access the upstream port device, where the downstream port device may be a first electronic device or a second electronic device, and the upstream port device may be a second electronic device or a first electronic device, which corresponds to the downstream port device.
In another implementation, determining a configuration relationship between the first electronic device and the second electronic device based on attribute information may include: if the attribute information characterizes that the first electronic device and the second electronic device belong to dual-role port devices, determining that a second configuration relationship exists between the first electronic device and the second electronic device, and under the second configuration relationship, any one of the first electronic device and the second electronic device can be switched into uplink port devices or downlink port devices under the target requirement.
In this implementation, the first electronic device and the second electronic device are DRP (dual role Power) devices, such as a mobile phone, a PAD, and the like, and the first electronic device and the second electronic device are both master devices, so that under a second configuration relationship, the first electronic device may be switched to an uplink port device based on a data communication requirement, accessed by the second electronic device, and may also be switched to a downlink device based on the data communication requirement, so as to access the second electronic device; the second electronic device is the same.
In yet another implementation, determining a configuration relationship between the first electronic device and the second electronic device based on attribute information may include: and if the attribute information characterizes that the first electronic equipment and the second electronic equipment respectively belong to downlink port equipment and dual-role port equipment, determining that a third configuration relation exists between the first electronic equipment and the second electronic equipment, and under the third configuration relation, the second electronic equipment is configured to be switched into uplink port equipment.
For example, the first electronic device is a desktop of the downlink port device, and the second electronic device is a dual-role port device, where in this case, it is determined that the mobile phone is an uplink port device, so that the desktop can access the mobile phone data and charge the mobile phone.
In yet another implementation, determining a configuration relationship between the first electronic device and the second electronic device based on attribute information may include: and if the attribute information characterizes that the first electronic device and the second electronic device respectively belong to an uplink port device and a dual-role port device, determining that a fourth configuration relation exists between the first electronic device and the second electronic device, and under the fourth configuration relation, the second electronic device is configured to be switched into a downlink port device.
For example, the first electronic device is an uplink port device usb disk, and the second electronic device is a dual-role port device notebook computer, where in this case, the usb disk is intelligent as a slave device, so that the notebook computer needs to be configured as a downlink port device, that is, a master device, so that the notebook computer can access the usb disk data.
The above details the implementation of several scenarios for determining a configuration relationship between two electronic devices based on attribute information, which is convenient for a person skilled in the art to better understand and implement the solution of the present application.
In the above embodiment, the target requirement may be a requirement determined based on target reference information, and the target reference information may include at least one of the following: device operation information (running application, current operation mode, etc.), device power information, device communication connection status (whether other devices are connected, roles played, etc.), and user selection. These target reference information may be used to assist in determining a configuration relationship between the first electronic device and the second electronic device.
Thus, the control method may further include, in addition to the steps disclosed in the foregoing embodiment: and obtaining target reference information from at least one of the first electronic equipment, the second electronic equipment and a target user, and controlling the first electronic equipment and the second electronic equipment to establish a first communication channel or a second communication channel based on the target reference information and the attribute information.
Specifically, controlling the establishment of the first communication channel or the second communication channel between the first electronic device and the second electronic device based on the target reference information and the attribute information may include: and under the condition that the attribute information characterizes that the first electronic equipment and the second electronic equipment belong to dual-role port equipment, controlling at least one of the first electronic equipment and the second electronic equipment to be switched into uplink port equipment or downlink port equipment based on at least one of operation information, power supply information, equipment connection information and user input information acting on the electronic equipment of the electronic equipment so as to establish the first communication channel or the second communication channel.
In the corresponding scenario, when it is determined that the first electronic device and the second electronic device are both dual-role port devices based on the obtained attribute information, it is further determined whether the two electronic devices are both configured as a master device or one of the two electronic devices is a master device and the other is a slave device, and then it is determined by combining the target reference information. For example, by determining that the first electronic device is currently running a remote control application through the target reference information obtained from the first electronic device, and by determining that the second electronic device is in the standby mode until the second electronic device is in the standby mode through the target reference information obtained from the second electronic device, the first electronic device can be determined as a master device, the second electronic device can be determined as a slave device, and the second communication channel corresponding to the master device-slave device is controlled to be established between the two electronic devices.
Or, controlling the first electronic device and the second electronic device to establish a first communication channel or a second communication channel based on the target reference information and the attribute information, including: and under the condition that the attribute information characterizes that the first electronic equipment and the second electronic equipment respectively belong to downlink port equipment and dual-role port equipment, controlling the second electronic equipment to be switched into uplink port equipment or downlink port equipment based on at least one of operation information, power supply information, equipment connection information and user input information acting on the electronic equipment of the electronic equipment so as to establish the first communication channel or the second communication channel.
In the corresponding scenario, the first electronic device is determined to be a downlink port device, namely a master device, and the second electronic device is determined to be a dual-role port device based on the obtained attribute information, so that whether the second electronic device is determined to be the master device or the slave device needs to be further determined. For example, if it is determined that the second electronic device has no power supply and the current power is lower than the set value through the target parameter information obtained from the second electronic device, it may be determined that the second electronic device is determined to be an upstream port device, that is, a slave device.
In other scenarios, the target reference information may be implemented differently. For example, an APP of a connection device for connecting the first electronic device and the second electronic device is installed in the first electronic device and/or the second electronic device, when the electronic device is a dual-role port device, after the first electronic device and the second electronic device are successfully connected, the corresponding APP pops up a prompt interface, so that a user selects a role of the current electronic device, that is, the electronic device is determined to be an uplink port device or a downlink port device according to a selection operation of the user. For another example, the target reference information characterizes the communication connection state of the device, including whether other devices are connected, roles played, and the like; for the dual-role port device, if it is determined that other USB devices are connected or are being charged based on the target reference information, the dual-role port device may be determined to be a downstream port device, that is, a master device; if it is determined that any other device is not connected based on the target reference information, it may be determined as an upstream port device, that is, a slave device, and further it is determined whether a first communication channel or a second communication channel is established between the first electronic device and the second electronic device.
In the specific implementation shown in fig. 2, the implementation manner and control logic of the switching of the HosttoHost (master-master corresponding to the first communication channel described above) and the Hosttodevice (master-slave corresponding to the second communication channel described above) paths are as follows: the ic with the cclogic function is integrated in the cable, the access equipment can be identified through the ccpin according to the typec standard protocol, then the cclogic outputs gpio to control the automatic switching of the 2-path USB channels, so that the intelligent cable can realize the intelligent switching of the mode of the access equipment which needs to work, and in addition, the intelligent cable app is also added with the automatic mode switching function to inform the access DRP equipment to switch to the corresponding channel. Wherein:
a. CClogic (CC logic control chip) accords with standard Typec protocol, and can support and identify DFP, UFP and DRP modes;
b. the intelligent cable is in a DFP mode by default through ccpin because one end of the intelligent cable is USBA and is connected to the PC;
c. when a typeC device supporting a DFP mode is accessed, after CClogic identifies that the access device is a DFP (Host), 2 USBSwitches in a GPIO control diagram can be used for enabling a usb signal of the access device to pass through a hostjostbridge, and simultaneously, the USBvccPOWER output of a typeC terminal is closed, so that communication between a PC and the Host device accessing the typeC can be realized;
d. When a typeC Device supporting UFP mode is accessed, CClogic recognizes that the access Device is UFP (Device), the Device transmits usb signals through 2 USBSwitches in a GPIO control chart and outputs USBvccpower, so that the access typeC Device is directly accessed to a PC through USBA, and power supply and communication between the PC and the access typeC slave Device are realized;
e. when a TypeC device supporting the DRP mode is accessed: since smartable defaults to DFP mode, the access DRP device automatically switches to UFP mode and then operates in the same manner as d above. Devices in the DRP mode, such as the access device, need to work with the function of the hosttop (DFP mode), and the smart cable can send a command to the access device side through the usb bypass channel signal to request the access device to switch to the DFP mode, and the communication principle is the same as the above c.
The control method can meet the connection requirements of different types of electronic equipment in different application scenes, realize different access rights between two connected electronic equipment through different communication channels, and meet different use requirements of two electronic equipment in work and life of a user.
