If no application program is currently opened, it is judged whether the parsing instruction contains the shortcut key value for opening the application program, if yes, then open the application program corresponding to the shortcut key, and enter step S408, otherwise, enter step S410.

S408: Whether the current application program can recognize the parsing instruction.

In step S408, the current application program judges whether the analysis instruction is valid, that is, whether the key value or handwriting input data or the sliding direction is valid for the current application program, if the analysis instruction is valid for the current application program, then enter step S409, otherwise, enter step S410 . For example, if the current application program is editing emails, editing short messages or editing URLs, if the parsing instruction contains correct handwritten input data letters, numbers, text, etc., then the parsing instruction is considered valid, and enters the next step S409 for editing operations, otherwise it is discarded This parsing instruction does not perform editing operations. As another example, if the current application is a game, the four sliding directions "↑", "↓", "←", and "→" are set to be valid. If the analysis instruction contains the values corresponding to the above four sliding directions, enter the next In step S409, the game operation is performed, otherwise the game operation is abandoned.

S409: Operate the current application program according to the parsing instruction.

In step S409, the current application program performs any of the following actions on the mobile phone's application program according to the meaning represented by the parsing instruction: application program startup, application program closing, camera focal length adjustment, photo automatic shooting, volume increase, volume down, backlight increase Large, backlight decrease, font increase, font decrease, browsing content scrolling down, browsing content scrolling up, browsing content page turning, game direction movement and information input, etc.

S410: end.

In step S804, the processor of the mobile phone detects the voltage of the detection pin of the connector of the mobile phone. If the voltage of the detection pin is low, it means that the protective cover is connected with the mobile phone, and enters the next step S805. Otherwise, it is not connected. , enter step S807.

S805: Transmitting a control command from the protective cover to the mobile phone.

In step S805, the data transmission protocol is a serial port protocol, and the control instruction is transmitted to the data signal pin and the clock signal pin of the connector of the mobile phone through the data signal pin and the clock signal pin of the connector of the mobile phone protective cover, and then passed The data signal pin and the clock signal pin of the connector of the mobile phone are transmitted to the CPU of the mobile phone.

S806: The mobile phone receives the control instruction and operates an application program of the mobile phone according to the control instruction.

The working method of step S806 is the same as that of step S206 above, and will not be repeated here.

S807: end.

The connector of this embodiment realizes the communication between the mobile phone protective cover and the mobile phone, provides power for the mobile phone protective cover, and controls the application program operation of the mobile phone through the buttons and touch panel on the mobile phone protective cover. This communication method is less costly than the wireless communication method. Of course, other ways can also be used to provide power for the mobile phone protective cover, such as using a button battery, a charging power chip, and the like. Other methods can also be used to detect the connection of the mobile phone protective cover to the mobile phone and to identify the type of the mobile phone protective cover. The data signal and the clock signal in the above embodiments are not necessarily transmitted through I ² C signals, and other bus types, such as SPI signals, may also be used.

In summary, the present invention realizes the communication between the mobile phone protective cover and the mobile phone, and the mobile phone protective cover is provided with buttons or touch pads to operate the application programs of the mobile phone, so that the user can operate the application programs on the mobile phone more conveniently and quickly. The phone cover is portable and easy to install.

The above is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the description of the present invention and the contents of the accompanying drawings, or directly or indirectly used in other related technologies fields, all of which are equally included in the scope of patent protection of the present invention.
