For example, the first object can be one or more. In addition, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / ", generally indicates that the front and rear associated objects are in an "or" relationship.

[0028] The interface state control method provided by the embodiments of the present application will be described in detail below in combination with the drawings, specific embodiments and application scenarios.

[0029] As shown in FIG. 1, the present application provides an interface state control method, which is applied to a first module of an electronic device, the first module includes a plurality of interfaces, the plurality of interfaces include a control interface and a data interface, the control interface is connected with a second module of the electronic device, and the method includes:

[0030] Step 101: in the case of detecting that the first module is powered on, starting the plurality of interfaces.

[0031] In the embodiments of the present application, the data interface includes at least one input interface and at least one output interface. Optionally, the input interface and the output interface correspond to each other.

[0032] For example, as shown in FIG. 2, the first module includes an input interface one, an input interface two, an output interface one and an output interface two. Among them, the input interface one corresponds to the output interface one, and the input interface two corresponds to the output interface two, that is, data is input from the input interface one and output from the output interface one; or, data is input from the input interface two and output from the output interface two.

[0033] Step 102: in the case that the control interface receives a first instruction sent by the second module, closing all data interfaces, wherein the first instruction is used to instruct to close all data interfaces.

[0034] In the embodiments of the present application, after the second module detects that the first module is powered on, the second module sends a first instruction to the first module, so that the first module closes all data interfaces according to the first instruction, thereby achieving the purpose of saving resource power consumption.

[0035] Optionally, the second module is a master module of the electronic device. For example, the master module is an electronic controller. The master module controls the opening or closing of each data interface of the first module by sending instructions.

[0036] Step 103: in the case that the control interface receives a second instruction sent by the second module, starting a first data interface in the data interface, wherein the second instruction is used to instruct to start the first data interface.

[0037] In the embodiments of the present application, in the case that the second module receives a use demand of a user using the first data interface, the second module sends a second instruction to the first module, and the first module starts the first data interface according to the second instruction, for example, the first data interface includes a first access interface and a first output interface.

[0038] Optionally, the user is a module other than the first module in the electronic device, or is a user.

[0039] In the embodiments of the present application, when the control interface is normal, closing the data interface through the first instruction can reduce unnecessary resource consumption, and when the user needs to use a specific data interface, the specific data interface can be opened through the second instruction, thereby ensuring the normal use of the data interface of the first module by the user. When the control interface is abnormal, since each interface is in an open state after the first module is powered on, the normal use of the data interface of the first module by the user can also be ensured, and therefore, the above-mentioned solution can ensure the normal use of the data interface of the first module regardless of whether the control interface is normal or not, that is, regardless of whether the first module can normally communicate with the second module or not.

[0040] Optionally, the method further comprises:

[0041] In the case that the control interface receives a third instruction sent by the second module, the first data interface is closed, wherein the third instruction is used to close the first data interface.

[0042] In the embodiments of the present application, when the second module learns that the user no longer needs to use the first data interface of the first module, the third instruction is sent to the first module through the control interface, and the first module closes the first data interface according to the third instruction, so as to avoid energy waste.

[0043] Optionally, the first instruction or the second instruction is an instruction transmitted through a serial communication protocol.

[0044] In the embodiments of the present application, the first module and the second module transmit the first instruction or the second instruction through a serial communication protocol, so as to open or close the corresponding interface according to the corresponding instruction. For example, the serial communication protocol can be an Inter-Integrated Circuit (I2C) protocol, a Serial Peripheral Interface (SPI) protocol, etc.

[0045] Optionally, the first module includes at least one of a power management module and a multimedia processing module, but is not limited thereto. The first module can be any functional module in the electronic device which includes multiple interfaces.

[0046] Through the solution of the present application, when the control interface is normal, the normal use of the interfaces of the power management module, the multimedia processing module, etc. can be ensured on the premise of avoiding unnecessary resource consumption, and when the control interface is abnormal, the normal use of the interfaces of the power management module, the multimedia processing module, etc. can also be ensured.

[0047] The overall flow of the interface state control method of the application will be described below in combination with an embodiment.

[0048] In the embodiment of the application, as shown in FIG. 3, the flow includes:

[0049] Step 301: power on the first module.

[0050] Step 302: the first module opens all interfaces.

[0051] After connecting the power supply, the first module will be initialized, and in the initialization process, the first module opens all interfaces and prepares to receive the communication instruction from the second module. The second module is specifically the master module of the electronic device.

[0052] Step 303: the second module sends a first instruction using a communication protocol, and the first instruction is used to instruct to close all data interfaces.

[0053] The communication protocol is a communication protocol for direct data exchange between the first module and the second module, such as I2C protocol, SPI protocol, etc.

[0054] Step 304: the first module closes all data interfaces.

[0055] Step 305: the second module learns that the user needs to use the first data interface, and sends a second instruction to the first module using the communication protocol, and the second instruction is used to instruct to open the first data interface.

[0056] The user is another module connected to the corresponding input or output of the first module, and the output or input of the user depends on the input interface or output interface of the first module being in an open state.

[0057] Step 306: the first module opens the first data interface.

[0058] After receiving the second instruction of opening the first data interface sent by the second module to the module through the communication protocol, the first module executes according to the instruction content, at this time the first data interface has its corresponding function to ensure the normal function of the user and the first module.

[0059] Step 307: the first data interface is normally used.

[0060] At this time, the corresponding function of the first data interface works normally.

[0061] Step 308: when the second module learns that the user no longer needs to use the first data interface, a third instruction is sent through the communication protocol, and the third instruction is used to close the first data interface.

[0062] Step 309: The first module closes the first data interface.

[0063] After receiving the instruction of closing the first data interface sent by the second module to the first module through the communication protocol, the first module executes the instruction, and at this time, the first data interface no longer has its corresponding function, and the function participated by the user and the first module no longer runs.

[0064] Step 310: The first module is powered off.

[0065] After the first module is powered off, all interfaces are closed.

[0066] In the above process, the control interface normally works, and through the above first instruction and second instruction, the normal use of the interface of the first module can be ensured on the premise of avoiding unnecessary resource consumption.

[0067] In the embodiment of the present application, as shown in FIG. 4, the process includes:

[0068] Step 401: The first module is powered on.

[0069] Step 402: The first module opens all interfaces.

[0070] After connecting the power supply, the first module will be initialized, and in the initialization process, the first module opens all interfaces and prepares to receive communication instructions from the master module.

[0071] Step 403: The second module sends a first instruction using a communication protocol, and the first instruction is used to indicate to close all data interfaces.

[0072] The communication protocol is a communication protocol for direct data exchange between the first module and the second module, such as I2C protocol, SPI protocol, etc.

[0073] Step 404: The control interface is abnormal, and all data interfaces of the first module remain in an open state.

[0074] Due to the abnormality of the control interface, the first module cannot receive the above-mentioned first instruction, and all data interfaces of the first module remain in an open state.

[0075] Step 405: The second module learns that the user needs to use the first data interface, and sends a second instruction to the first module using a communication protocol, and the second instruction is used to indicate to open the first data interface.

[0076] The user is another module connected to the corresponding input or output of the first module, and the output or input of the user depends on the input interface or output interface of the first module being in an open state.

[0077] Step 406: control the interface exception, and all data interfaces of the first module remain in an open state.

[0078] Due to the control interface exception, the first module cannot receive the second instruction, and all data interfaces of the first module remain in an open state. At this time, the first data interface has its corresponding function, and the function of the user and the first module can be ensured to be normal.

[0079] Step 407: the first data interface is normally used.

[0080] At this time, the corresponding function of the first data interface is normally working.

[0081] Step 408: when the second module learns that the user no longer needs to use the first data interface, a third instruction is sent through a communication protocol, and the third instruction is used to close the first data interface.

[0082] Step 409: control the interface exception, and all data interfaces of the first module remain in an open state.

[0083] Due to the control interface exception, the first module cannot receive the third instruction, and all data interfaces of the first module remain in an open state.

[0084] Step 410: the first module is powered off.

[0085] After the first module is powered off, all interfaces are closed.

[0086] In the above process, the control interface is abnormal, and the first module and the second module cannot normally communicate. However, because each interface of the first module is in an open state after the first module is powered on, the user can normally use the data interface of the first module when the first module and the second module cannot normally communicate.

[0087] The interface state control method provided in the embodiment of the application can be executed by the interface state control device. In the embodiment of the application, the interface state control method executed by the interface state control device is taken as an example to illustrate the interface state control device provided in the embodiment of the application.
