Embodiment
In order more clearly to understand above-mentioned purpose of the present invention, feature and advantage, below in conjunction with the drawings and specific embodiments, the present invention is further described in detail.
More details have been set forth in the following description so that fully understand the present invention; but; the present invention can also adopt other to be different from other modes described here and implement, and therefore, protection scope of the present invention is not subject to the restriction of following public specific embodiment.
Embodiment 1:
Embodiments of the invention 1 provide a kind of method that realizes mobile terminal USB OTG function, Fig. 1 is according to the schematic flow sheet of the embodiment of the present invention 1, please refer to Fig. 1, this method is applied to as on the mobile terminal of the compatible USB OTG of the CPU such as mobile phone, PDA, palm PC function.Wherein, described OTG is On The Go, and it can make the mobile terminal can be at USB main equipment and USB from mutually switching between equipment; When mobile terminal is connected to PC(personal computer) time, as a common USB from equipment, and when mobile terminal is connected from equipment with other USB, it is just as USB main equipment.Mobile terminal of the present invention, the compatible USB OTG of its CPU function, but it is unsettled for identifying USB from the ID pin of equipment, the hardware circuit of mobile terminal do not draw connect this pin lead-in wire out, although the therefore compatible USB OTG of this type of mobile terminal CPU, but due to the defect on hardware, cause the external USB of its None-identified from equipment, still do not possess USB OTG function.
On corresponding mobile terminal (as mobile phone, PAD etc.), be provided with after the present invention, comprise the steps:
The USB OTG function of S1, user's choice for use mobile terminal or USB function;
Wherein, more specifically, due to the defect on mobile terminal hardware, when inserting USB, mobile terminal cannot judge external be USB from equipment or USB main equipment, so offer user, initiatively select, realize and initiatively judge that external equipment is that USB is from equipment or USB main equipment, thereby realize according to actual demand, for user presents USB OTG function or the USB function of mobile terminal.
As the preferred scheme of one, the concrete grammar of described user's choice for use USB OTG function or USB function is:
Inserting after USB device, on mobile terminal, eject choice menus, for USB OTG function or the USB function of user's choice for use mobile terminal; Therefore user can according to the actual requirements, independently select corresponding function; If user's's selected " USB OTG function " respective menu, represent so external equipment be USB from equipment, need to be USB main equipment by mobile terminal configuration, for user presents USB OTG function; If user's's selected " USB function " respective menu represents that external equipment is USB main equipment so, mobile terminal as generic USB from equipment, for user presents USB function.
Certainly, for the simplicity of further lifting operation, avoid the loaded down with trivial details of operation, also can before inserting USB device, select.As: before insertion USB device, user, by recalling corresponding menu item, carries out choice for use mobile terminal USB OTG function by menu; And in the method, mobile terminal acquiescence USB recognition mode be USB from equipment, therefore, if do not select USB OTG function before external USB device, giving tacit consent to so mobile terminal configuration is that USB is from equipment, for user presents USB function.
If the USB OTG function of S2 choice for use mobile terminal, adopt down trigger mode or thread triggering mode, triggering system starts USB OTG function, by mobile terminal configuration, it is USB main equipment, and external USB is identified from equipment, mobile terminal and external USB realize exchanges data from equipment;
More specifically, by when mobile terminal configuration is USB main equipment, also the charging process of mobile terminal is configured, charging is made as to disable, OTG function is made as to enable, and the process configuration of now charging is is that circumscribed USB is powered from equipment from mobile terminal.In the present embodiment, can use oppo_otg_enable variable to judge.
Be 1:: CHG_CONTROL__DISABLE|OTG_SWITCH__ENABLE;
Be 0:: CHG_CONTROL__ENABLE|OTG_SWITCH__DISABLE.
And external USB is identified from equipment, such as external USB is mouse from equipment, it is after mouse inserts that mobile terminal system identifies, and shows the arrow of mouse in the figure on upper strata layer; If what insert is USB flash disk, mobile terminal bottom will read the attribute of USB flash disk, such as ID producer, size, and USB flash disk carry on node, confession upper strata is read and is called.
If the USB function of S3 choice for use mobile terminal is that USB is from equipment, for user presents USB function by mobile terminal configuration.
More specifically, described employing down trigger mode, the detailed process that triggering system starts USB OTG function is:
After the USB of choice for use mobile terminal OTG function, to be defaulted as high level and become low level for the GPIO mouth of identifying OTG, now, the CPU(central processing unit of mobile terminal) detect that described GPIO mouth becomes low level, illustrated that USB inserts and triggered interrupt condition from equipment, produces look-at-me;
When judging USB, normally inserts from equipment CPU, the function that will call USB OTG is so processed, some variablees and the condition of first initialization OTG, then notify upper strata USB to insert from equipment, realization will be USB main equipment to mobile terminal configuration, and identify from equipment external USB, and then make mobile terminal and external USB realize exchanges data from equipment.
And described employing thread triggering mode, triggering system starts USB OTG function detailed process and is:
After the USB of choice for use mobile terminal OTG function, by upper strata, receive " using USB OTG function " broadcast and carry out thread scheduling, directly calling the function of USB OTG processes, directly enter usb_is_host() function, by mobile terminal configuration, it is USB main equipment, and external USB is identified from equipment, realize mobile terminal and external USB and carry out exchanges data from equipment.
Implement after the present invention, for providing a kind of hardware at mobile terminal, user do not support USB OTG function, but during the compatible USB OTG of CPU function, also can realize the method for using USB OTG function, promoted greatly the intelligent of this Terminal Type, promoted this type of terminal user's experience, practical.
Embodiment 2
Embodiments of the invention 2 provide a kind of device of realizing mobile terminal USB OTG function, and Fig. 2 is the structural representation block diagram according to the embodiment of the present invention 2, and described device comprises:
