Technical field
The utility model relates to art of keypads, particularly a kind of programmable keyboard and electronic product.
Background technology
Fig. 1 shows the syndeton synoptic diagram between programmable keyboard of the prior art and the main frame.As shown in Figure 1, programmable keyboard of the prior art needs could get into programming state through some operation (for example pressing some fixing button) when programming.Need after programming finishes to treat to withdraw from programming state, just can get into normal user mode, have the shortcoming of complex operation, very flexible, poor stability through some operation (for example re-power or carry out some specific operation).
The utility model content
The purpose of the utility model provide a kind of simple to operate, dirigibility good, high programmable keyboard and the electronic product of stability.
For addressing the above problem, an aspect as the utility model provides a kind of programmable keyboard, comprising: the keyboard scan unit; Storage unit; Usb interface unit; And microcontroller, comprising: control module is electrically connected with keyboard scan unit, storage unit and usb interface unit; And the device enumeration unit, being electrically connected with control module, it is to be used as first equipment of keyboard and second equipment that is used to programme that programmable keyboard is enumerated.
Further, programmable keyboard also comprises: the PS2 interface is electrically connected with control module.
Further, programmable keyboard also comprises: the magnetic card reading unit is electrically connected with control module.
Further, programmable keyboard also comprises: alarm unit, be electrically connected with control module, and be used for sending alerting signal according to the result that reads of magnetic card reading unit.
Further, alarm unit is a hummer.
Further, programmable keyboard also comprises: pilot lamp is electrically connected with control module.
Another aspect as the utility model provides a kind of electronic product, comprises programmable keyboard, and this programmable keyboard is above-mentioned programmable keyboard.
The utility model is enumerated two USB devices through the device enumeration unit to main frame, therefore, can directly carry out online programming and not need any operation bidirectional programmable keyboard through main frame, has characteristics simple to operate, that dirigibility good, stability is high.
Description of drawings
Fig. 1 shows the syndeton synoptic diagram between programmable keyboard of the prior art and the main frame.
Fig. 2 is the structural representation of the utility model.
Embodiment
As the first aspect of the utility model, a kind of programmable keyboard is provided.As shown in Figure 2, the programmable keyboard in the utility model comprises: keyboard scan unit, storage unit and, usb interface unit and microcontroller.The keyboard scan unit is used for keyboard is scanned, to confirm that which key is pressed.Storage unit is used for storing the relevant information of the key of the programmable keyboard of the utility model being programmed through main frame.Microcontroller comprises: control module and device enumeration unit.Wherein, control module is electrically connected with keyboard scan unit, storage unit and usb interface unit.The device enumeration unit is electrically connected with control module, programmable keyboard is enumerated be first equipment that is used as keyboard and second equipment that is used to programme.
Two equipment can be enumerated to main frame in the device enumeration unit, i.e. first equipment and second equipment.In the time need programming to the programmable keyboard in the utility model; Can carry out communication through the usb interface unit of main frame and second equipment of the utility model; (for example the user can use mouse and be installed in the application program in the main frame on the screen at main frame at the key information of setting on the main frame with the user; Particularly the soft keyboard that carries of this application program is programmed to the programmable keyboard in the utility model) send to the programmable keyboard in the utility model through second equipment, thus realize the function of programming; Simultaneously, can the relevant information of programming be stored in the storage unit.After programming finishes, can carry out communication through the usb interface unit of main frame and first equipment of the utility model, thereby the key information that the user presses is sent to main frame through first equipment.Therefore; Need be as programmable keyboard of the prior art; The specific operation (for example pressing certain several key) that needs the user to pass through programmable keyboard could get into and withdraw from programming state; Need not re-power restart facility yet, have characteristics simple to operate, that dirigibility good, stability is high.In addition, the main frame of the applicable several operation systems of programmable keyboard in the utility model, for example: windows, linux, wince, MAC etc.Especially, because employing is the usb interface unit of standard, therefore extra any driver need be installed under windows and can uses.
Preferably, programmable keyboard also comprises: the PS2 interface is electrically connected with control module.Like this; Can the peripheral hardware of some PS2 interfaces and the programmable keyboard in the utility model be coupled together use; For example; The bar code scanner and the programmable keyboard that will have the PS2 interface couple together, and send to main frame with the convenient information that these peripheral hardwares are obtained through programmable keyboard, are specially adapted to those main frames that do not have the PS2 interface and use.
Preferably, programmable keyboard also comprises: the magnetic card reading unit is electrically connected with control module.This magnetic card reading unit is used to read the relevant information of smart cards such as bank card, and it is sent to main frame through first equipment, is particularly suitable for occasion uses such as supermarket.Further, programmable keyboard also comprises: alarm unit, be electrically connected with control module, and be used for sending alerting signal according to the result that reads of magnetic card reading unit.Preferably, alarm unit is a hummer.For example, when the information that reads when the magnetic card reading unit was correct, alarm unit sent a kind of alarm sound, and when the information that reads when the magnetic card reading unit was incorrect, alarm unit sent another kind of alarm sound, to remind operating personnel's attention.
Preferably, programmable keyboard also comprises: pilot lamp is electrically connected with control module.Through this pilot lamp, can indicate the state of the special key on the keyboard, for example the state of CapsLck, NumLck key is opened or is closed, and is not limited to these buttons certainly, and the user can freely set through the mode of programming.
As the second aspect of the utility model, a kind of electronic product is provided, comprise programmable keyboard, this programmable keyboard is the programmable keyboard among above-mentioned each embodiment.For example, this electronic product can be computer, cashier's machine etc.
