Embodiment
Relevant characteristics and implementation of the present invention cooperate diagram to be described in detail as follows as most preferred embodiment now.
Please refer to Fig. 1, represented the automatic checkout system of note type computer keyboard interface of the present invention among the figure.This system runs in the mobile computer 10, includes USB (universal serial bus) (USB) communication module 16, matrix switch chip 18 (better embodiment can be realized by for example MT8816 chip or other similar switch module), breakout box 20 and testing software 12.USB (universal serial bus) communication module 16 can be the USB communication fixture of a Cy7c68013 main control chip, and it is received in the order of the testing software 12 of operation in the mobile computer 10 by USB port, and is converted to control signal.The order that testing software 12 transfers to USB (universal serial bus) communication module 16 comprises desire test key position value, i.e. the ranks value of button in mobile computer 10.
As shown in Figure 1, automatic checkout system of the present invention also comprises a breakout box 20, be connected between the Basic Input or Output System (BIOS) (BIOS) 14 of the X/Y line interface of the matrix switch chip 18 that comprises the MT8816 chip and mobile computer 10, be used for the conversion of signals that the MT8816 keyboard matrix is sent.Because the row, column line number of the keyboard interface of different mobile computer motherboards is different with the position, therefore need realizes that different interfaces uses identical MT8816 keyboard matrix, and then keyboard state is reflected in the mobile computer 10 by breakout box.
In testing software 12, include comparison module, receive true key position state value, and the desire test key position value that this location status value is sent with it is compared, and then finish the test of one-touch by keyboard interface.
In addition, automatic checkout system of the present invention can also comprise one scan software, obtaining a keyboard position corresponding tables by scanning notes type computer keyboard array, and then provides desire test key position value to testing software 12.And above-mentioned position corresponding tables also can be provided by the manufacturer of keyboard.
Please refer to Fig. 2 now, this figure is the flow chart of steps of the automatic testing method of a kind of note type computer keyboard interface of the present invention, as shown in Figure 2, the automatic testing method of note type computer keyboard interface of the present invention comprises following steps: " keyboard position corresponding tables " (step 102) of button in matrix that at first needs to obtain in advance according to different mobile computers its true keyboard, above-mentioned position corresponding tables can be provided by the manufacturer of keyboard, perhaps utilizes scanning software to obtain.By all point of crossing of array keyboard scan, and then obtain the key position of true keyboard.Then, mobile computer needs a certain button (for example A key) when pressing, and testing software wherein finds the position (row, column value) (step 104) of this key in " keyboard position corresponding tables ".Then, by the test command (step 106) that a universal serial bus device acceptance test software sends, wherein test command comprises desire test key position value.The USB (universal serial bus) communication device of test transmission order can be the USB communication fixture of a Cy7c68013 main control chip, and it passes through USB port acceptance test order, and is converted to control signal.
Then, the USB (universal serial bus) communication device is sent to test control signal in the dummy keyboard matrix that utilizes at least one matrix switch chip to constitute, and then according to the testing software order of USB (universal serial bus) communication device transmission, the a certain point of crossing of corresponding key position opens with closed, with the true actuation of keys (step 108) of emulation mobile computer keyboard in the control dummy keyboard matrix.In this, the matrix switch chip can be that for example MT8816 chip and other have the switch module of similar functions.In this embodiment, the dummy keyboard matrix can be made of the matrix switch chip of a MT8816 chip, to form 8 * 16 dummy keyboard matrix; Perhaps can constitute,, can cover all keyboard interfaces at present like this to form 8 * 16,8 * 32 or 16 * 16 dummy keyboard matrix by the matrix switch chip of two MT8816 chips.
According to embodiment, be connected to a switching device 20 by the MT8816 matrix switch chip of forming the dummy keyboard matrix, the signal that MT8816 dummy keyboard matrix sends is changed (step 120).Breakout box is connected between the Basic Input or Output System (BIOS) (BIOS) of the X/Y line interface of MT8816 matrix switch chip and mobile computer, because the row, column line number of the keyboard interface of different mobile computer motherboards is different with the position, therefore need realize that different interfaces uses identical MT8816 keyboard matrix by breakout box, and then keyboard state is reflected in the mobile computer.
Breakout box is connected with the keyboard matrix of MT8816 chip by the X/Y line interface, and the X/Y line comprises the signal wire of capable (X) line and row (Y) in the MT8816 keyboard matrix.And be connected to the keyboard interface of mobile computer motherboard by the sweep trace interface.The effect of breakout box is the sequence correspondence that realizes the row, column line of MT8816 keyboard matrix row, column line in the keyboard interface of mobile computer motherboard.
After the Basic Input or Output System (BIOS) reception of tandem signal by mobile computer, true key position state value promptly transfers to testing software, therefore testing software compares the desire test key position value that this true keyboard position state value sends with it, and then finishes the test (step 122) of one-touch.
Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the present invention.
