Abstract
The utility model provides a SD card starts debugging acid, SD card starts debugging acid connects including control mainboard, SD card slot, SD signal switch chip and two signals, SD card slot the SD signal switch chip and two signals connect to be located respectively on the control mainboard, just SD card slot the SD signal switch chip and two signals connect respectively with control mainboard electric connection. The utility model provides a SD card starts debugging acid need not frequent plug SD card, and the debugging is got up very conveniently.
Description
Technical field
The utility model relates to the debugging acid equipment used in embedded development, particularly relates to a kind of SD card start-up debugging acid.
Background technology
Along with the development that microelectric technique and wound passenger traffic are moved, increasing software developer and ordinary populace can touch the undersized single card microcomputer/mini computer of low cost, in order to reduce costs, the storage that this kind of single card microcomputer does not often have plate to carry, but the SD/MicroSD card that use one is external, by development equipment (PC) card reader, system image is write on SD/MicroSD card, insert the SD/MicroSD card slot of target device (single card microcomputer/mini computer), thus electrifying startup.On stream, common step is, target device power-off, SD/MicroSD card is inserted card reader, and card reader inserts development equipment, the program of write target device, pull up SD/MicroSD, be inserted into target device, start target device, check program operation result, if do not conformed to, target device power-off, pulls up SD/MicroSD card, be inserted into card reader, card reader inserts development equipment ... above-mentioned steps is to procedure result is satisfied so repeatedly.This mode needs plug SD/MicroSD card many times, and power-off/power on target device is many times very loaded down with trivial details and consuming time, makes troubles to debugging.
Utility model content
The purpose of this utility model there are provided a kind of SD card start-up debugging acid, and without the need to frequently plugging SD card, debugging is got up very convenient.
The utility model is achieved in that
A kind of SD card start-up debugging acid, described SD card start-up debugging acid comprises control mainboard, SD card slot, SD signal switching chip and two Signal connectors, described SD card slot, described SD signal switching chip and described two Signal connectors are located on described control mainboard respectively, and described SD card slot, described SD signal switching chip and described two Signal connectors are electrically connected with described control mainboard respectively.
As the improvement of above-mentioned SD card start-up debugging acid, described two Signal connectors comprise SD card signal plug and usb signal slot.
As the improvement of above-mentioned SD card start-up debugging acid, described SD card start-up debugging acid also comprises the relay be located on described control mainboard, and described relay and described control mainboard are electrically connected.
The beneficial effects of the utility model are: the SD card start-up debugging acid that the utility model provides, it comprises control mainboard, SD card slot, SD signal switching chip and two Signal connectors, make it to be connected respectively with target device and development equipment by two Signal connectors simultaneously, during debugging, only SD card need be injected its SD card slot, the instruction of SD signal switching chip just by accepting development equipment freely switches SD signal between development equipment and target device, without the need to frequently plugging SD card, debugging is got up very convenient.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the one-piece construction schematic diagram of a kind of preferred embodiment of the utility model SD card start-up debugging acid.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, the present embodiment provides a kind of SD card start-up debugging acid 1, SD card start-up debugging acid 1 comprises control mainboard 11, SD card slot 12, SD signal switching chip 13 and two Signal connectors, wherein, SD card slot 12, SD signal switching chip 13 and two Signal connectors are located at respectively and are controlled on mainboard, and SD card slot 12, SD signal switching chip 13 and two Signal connectors are electrically connected with control mainboard 11 respectively.
In the present embodiment, as shown in Figure 1, two Signal connectors comprise SD card signal plug 14 and usb signal slot 15, so, during work, SD card signal plug 14 inserts in the SD card slot 21 of target device 2, this SD card start-up debugging acid 1 just can be connected with settling signal between target device 2, and meanwhile, development equipment 3 inserts in usb signal slot 15 by USB data line, this SD card start-up debugging acid 1 just can be connected with settling signal between development equipment 3, and whole operating process is simple and convenient.In addition, SD card start-up debugging acid 1 also comprises the relay 16 be located at and controlled on mainboard 11, and relay 16 is electrically connected with control mainboard 11.During work, relay 16 can be electrically connected with target device 2, can the powering on or power-off of control objectives equipment 2 automatically by relay 16, without the need to manual operation, and then improves debugging efficiency.
The SD card start-up debugging acid that the present embodiment provides, it comprises control mainboard, SD card slot, SD signal switching chip and two Signal connectors, make it to be connected respectively with target device and development equipment by two Signal connectors simultaneously, during debugging, only SD card need be injected its SD card slot, the instruction of SD signal switching chip just by accepting development equipment freely switches SD signal between development equipment and target device, and without the need to frequently plugging SD card, debugging is got up very convenient.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
