Embodiment
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
A kind of wireless SD card structure synoptic diagram that Fig. 1 provides for the utility model embodiment, as shown in Figure 1, this is wireless, and the SD card comprises main control unit 10 and wireless transmission unit 20, main control unit 10 is provided with the GPIO input port, this GPIO input port connects a switchgear 30, and the level value of the GPIO input port of main control unit 10 can be set by switchgear 30.Main control unit 10 reads corresponding configuration parameter according to the level value of GPIO input port from nonvolatile memory 40, and control wireless transmission unit 20 starts corresponding mode of operation.For example, put when high when the level value of the GPIO of main control unit 10 input port, main control unit 10 will be configured to ap mode to the mode of operation of wireless transmission unit 20 when powering on.
Need to prove that above-mentioned nonvolatile memory 40 is used for storage program and the parameter relevant with main control unit 10 operations, it can be to be integrated in the main control unit 10, also can be independent of (as shown in Figure 3) outside the main control unit 10.
In an example, switchgear 30 can adopt one to be electrically connected physical switch, is electrically connected physical switch by control, the level value of the GPIO input port of main control unit 10 can be put height or is put low.For example, when the default value of GPIO input port is high level, by being electrically connected physical switch the GPIO input port is linked to each other with a low level, when being electrically connected the physical switch closure, the GPIO input port is in low level state; When the electrical connection physical switch was opened, the GPIO input port was in high level state.Equally, when the default value of GPIO input port is low level, then by being electrically connected physical switch the GPIO input port is linked to each other with a high level, when being electrically connected the physical switch closure, the GPIO input port is in high level state; When the electrical connection physical switch was opened, the GPIO input port was in low level state.
The another kind of wireless SD card structure synoptic diagram that Fig. 2 provides for the utility model embodiment, as shown in Figure 2, the difference of this is wireless SD card and wireless SD card shown in Figure 1 is, the wireless transmission unit 20 of wireless SD card is built in the main control unit 10, thereby has effectively saved the inner space of wireless SD card.
Fig. 4 is wireless SD card course of work synoptic diagram.As shown in Figure 4, the course of work of wireless SD card is as follows:
Wireless SD card powers on, the Bootloader program start, the Bootloader program at first detects the level value of GPIO input port, when the level value of GPIO input port is high level, the Bootloader program will be visited the AP parameter of preserving in the nonvolatile memory, and call the AP start-up routine, make wireless SD card be operated in ap mode (ap mode be numbered mode of operation 1).
Under ap mode, wireless SD card will be according to Default Value or the self-built Wi-Fi Hotspot of user-defined parameter and the webserver, Default Value or User Defined parameter comprise: SSID(Service Set Identifier, service set), cipher mode, access key, working channel, signal intensity etc.Other Wi-Fi Stat ion equipment can be linked on this Wi-Fi Hotspot, and visits the data of this wireless SD card according to authority.
In an example, other Wi-Fi Station equipment can be visited the configuration page of AP by modes such as webpage, clients, and the running parameter of self-defined Wi-Fi Hotspot and AP.These parameters are kept in the nonvolatile memory.When system restart, wireless SD card will be set the running parameter of AP according to new configuration.After by format or alternate manner factory reset, all parameters of wireless SD card will return to the default setting that dispatches from the factory.
In another example, other Wi-Fi Station equipment can be visited the configuration page of AP by modes such as the page, clients, switch to GPIO is put when low can setting on this configuration page when being electrically connected physical switch, the mode of operation of wireless SD card, and the running parameter under this pattern.These parameters will be stored on the nonvolatile memory.
As shown in Figure 4, when detected GPIO input port is low level, the Bootloader program will be visited nonvolatile memory, and according to the parameter on the nonvolatile memory, call corresponding program, and allowing wireless SD card be operated on the corresponding mode of operation, its running parameter is also determined by the parameter that is kept on the nonvolatile memory.These mode of operations comprise Station pattern (mode of operation 2), Wi-Fi Direct pattern (mode of operation 3), Ad-hoc pattern (mode of operation 4), another ap mode (mode of operation 5), or close in the wireless module (mode of operation 6) one or more.
Fig. 5 is that the running parameter under the wireless SD card AP mode of operation switches synoptic diagram.As shown in Figure 5, when being stuck in mode of operation, wireless SD receives for 1 time when need revising corresponding running parameter request, can pass through Wi-Fi Station device access AP, enter the configuration page, and by the modification of the configuration page and preservation AP parameter, after automatic or manual was restarted wireless SD card, wireless SD card will be operated under the ap mode according to new parameter.
Fig. 6 is that the running parameter under wireless its mode of operation of SD khaki switches synoptic diagram.As shown in Figure 6, when wireless SD card is operated in mode of operation 2, mode of operation 3, mode of operation 4, a kind of (being set at mode of operation A) in mode of operation 5 or the mode of operation 6, the parameter that needs the modification Mode A, when needing that perhaps mode of operation is adjusted into another kind (being set at mode of operation B) in the above-mentioned mode of operation, can the GPIO input port be set to high level by stirring the electrical connection physical switch, enter mode of operation 1 after allowing wireless SD card restart, it is ap mode, use this AP of other Wi-Fi Station device access then, after corresponding parameter being made amendment and is saved on the nonvolatile memory, by being electrically connected physical switch the GPIO input port is set to low level again, after restarting wireless SD card, this moment, wireless SD card will carry out work according to new mode of operation or new running parameter.
When needs switch to mode of operation 1 from other pattern, namely during ap mode, only need push GPIO is put high position being electrically connected physical switch, restart wireless SD card, system will be operated in mode of operation 1, i.e. ap mode.
Application example of the present utility model is not limited to by being electrically connected physical switch the height of putting of GPIO be realized wireless SD card is configured to ap mode, GPIO is put hang down to realize the SD card is configured to other mode of operation; It is equally applicable to by being electrically connected physical switch putting of GPIO be hanged down to realize wireless SD card is configured to ap mode, GPIO is put height realize wireless SD card is configured to other patterns.
Application example of the present utility model is not limited to revise the parameter under all working pattern under ap mode, when a kind of mode of operation of setting is default mode of operation, equally also can revise the parameter of all working pattern under this pattern.
The wireless SD cartoon that the utility model embodiment provides is crossed increases an electrical connection physical switch, and the configuration of the software of wireless SD card inside, has realized that wireless SD is stuck in the switching between the different mode.
Above-described embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the above only is embodiment of the present utility model; and be not used in and limit protection domain of the present utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
