Detailed description of the invention
Fig. 1 is the flow chart of the preferred embodiment for the method that the present invention obtains WIFI information.
Fig. 2 is the functional schematic block diagram of smart television preferred embodiment of the present invention.
Specific embodiment
To make the objectives, technical solutions, and advantages of the present invention clearer and more explicit, right as follows in conjunction with drawings and embodiments
The present invention is further described.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and do not have to
It is of the invention in limiting.
A kind of method of acquisition WIFI information described in present pre-ferred embodiments, as shown in Figure 1, which comprises
S100, read usb bus on all devices PID and VID information after, traverse the internal PID and VID of preparatory static maintenance
The mapping table of respective modules model.
Further, the step S100 is specifically included:
S101 opens the UI program for obtaining WIFI information；
S102 accesses usb file system, PID the and VID information of all devices on usb bus is read by specific program；
S103 traverses the internal PID of preparatory static maintenance and the mapping table of VID respective modules model, obtains the PID of usb bus
WIFI module model corresponding with VID equipment and WIFI manufacturer name.
Specifically, according to the regulation of USB specification, all USB device Dou You supplier ID(VID) and product ID
(PID), host distinguishes different equipment by different VID and PID, and VID and PID are two byte longs, wherein supply
Quotient ID(VID) from supplier to the application of USB execution forum, the VID of each supplier is uniquely that PID is voluntarily determined by supplier
It is fixed, theoretically for, different products, the different model of like products, the different designs of same model product preferably with
Different PID, to distinguish the distinct device of identical producer.
There are two types of storage modes under normal conditions by VID and PID, the first is the VID and PID of master control manufacturer, is stored in
In the bootcode of master control；For second the VID and PID of equipment manufacturer, the VID and PID be stored in outside master control it is non-easily
In the property lost storage equipment in the equipment firmware of (EEPROM or Flash), when USB device connects host, if set in firmware
The VID and PID of standby manufacturer, can report the VID and PID to host, and ignore the VID and PID of master control manufacturer.So reason
VID by a upper USB storage device should be the VID of equipment manufacturer, rather than the VID of master control manufacturer, the two VID
It should be different (except the equipment of master control manufacturer oneself production).
It, here can be by lsusb shell(lsusb order for showing the machine by accessing usb file system
The details of USB device list and USB device) program (specific program is lsusb shell program) acquisition, it can
PID the and VID information of the equipment of carry on all usb bus is obtained, such as:
Bus 002 Device 006: ID 15d9:0a37 ；
Bus 002 Device 001: ID 0000:0000；
Wherein, indicate to have accessed two equipment on No. 002 USB host controller: one is USB root Hub -- 001, one is
USB mouse -- 006.
Traverse the internal PID of preparatory static maintenance and the mapping table of VID respective modules model, find usb bus PID and
The corresponding module model of VID equipment and chip manufacturer name, mapping table citing realize that this example is realized with C language:
typedef struct
{
char id[16];
char name[16];
char vendor[16]
}IDList;
IDList idlist[] = {
{ " 0bda:b812 ", " RTL8812BU ", " RealTek " },
{ " 0bda:8812 ", " RTL8812AUS ", " RealTek " },
{ " 0bda:8194 ", " RTL8192DU ", " RealTek " },
{ " 0bda:818b ", " RTL8192EU ", " RealTek " },
{ " 0bda:8813 ", " RTL8814AU ", " RealTek " },
{ " 0bda:8176 ", " RTL8192CU ", " RealTek " },
{ " 0bda:8178 ", " RTL8192CU ", " RealTek " },
{ " 0bda:0179 ", " RTL8188ETV ", " RealTek " },
{ " 148f:7601 ", " MT7601STA ", " MediaTek " },
{ " 0e8d:0000 ", " MT7602STA ", " MediaTek " },
{ " 0e8d:7603 ", " MT7603STA ", " MediaTek " },
{ " 0e8d:0000 ", " MT7612STA ", " MediaTek " },
{ " 0e8d:7632 ", " MT7662STA ", " MediaTek " },
{ " 0a5c:bd27 ", " BCM43569 ", " Broadcom " },
{ " 0a5c:0bdc ", " BCM43569 ", " Broadcom " },
}；
From the statement of above-mentioned IDlist it is recognised that id variable represents PID and VID, name variable represents WIFI module model,
Vendor represents WIFI manufacturer name；It is defined from idlist it is recognised that all current Android TVs that built-in mapping table includes
The integrated WIFI scheme information of manufacturer.
S200 judges that PID the and VID information of all devices on usb bus whether in the mapping table, passes through when being
Internal PID and VID obtain WIFI module model and WIFI manufacturer name.
Specifically, if the PID and VID of carry equipment are found in mapping table on usb bus, illustrate built in this algorithm
Module list in there is the information of this USB device to obtain name (WIFI module model) and vendor by internal PID and VID
(WIFI manufacturer name) drives version followed by WIFI to be obtained.
In addition, being in by the interface UI when PID the and VID information of all devices on usb bus is not in the mapping table
Existing prompt information, prompts user to update the mapping table of internal PID and VID respective modules model, this means the equipment of this usb bus
For newer WIFI module, program does not add corresponding module PID and VID information.
S300 obtains WIFI by the corresponding module drive interface of access sys file system and drives version number, will acquire
WIFI information shown by the interface UI.
Further, the step S300 is specifically included:
S301 is driven after getting WIFI module model and WIFI manufacturer name by the corresponding module of access sys file system
Mobile interface obtains WIFI and drives version number；
S302, the WIFI module model that will acquire, WIFI manufacturer name and WIFI driving version number are carried out by the interface UI
Display.
Specifically, the WIFI information includes: WIFI module model, WIFI manufacturer name and WIFI driving version number.
By the way that module name has been obtained, pass through the corresponding module drive interface/sys/module/ module of access sys file system
Model/version, available WIFI drive version number, finally notice following information: WIFI manufacturer name at the interface user UI
Word, WIFI module model and WIFI drive version number.
The present invention obtains the PID and VID of all USB devices from usb bus, passes through traversal embedded Static maintenance
PID and VID respective modules model mapping table, find corresponding module model, according to module model, go sys file system
Module catalogue find the driving version interface of respective modules model, finally feed back WIFI manufacturer name, WIFI module model
Version number gives program user with WIFI driving, and the functional defect in perfect industry improves the user experience of product, significantly
Enhance product competitiveness.
