Embodiment
Hereinafter with reference to correlative type, illustrate according to the computer apparatus of the embodiment of the invention with and the startup method of function.
Below please refer to Fig. 1, Fig. 1 illustrates the synoptic diagram of an embodiment of computer apparatus of the present invention.Computer apparatus 100 in the present embodiment comprises the operating system unit 130 and the basic input-output system unit 140 of function key 110, controller 120, built-in application program 131.Include many Fn keys (for example F1～F12 key) or extra additional key on the function key 110 wherein.And these Fn keys are all respectively represented a function usually, and for example the F1 key can be adjusted the contrast of screen, and F2 can adjust the brightness of screen etc., and extra function key then is when the Fn key does not apply use, in addition the additional key of Zeng Jiaing.
When the user will use the preset function of computer apparatus 100, just can push corresponding function key 110, at this moment, the control signal that produces when controller 120 receives being pressed of function key 110, and send one group of pre-set scan code to operating system unit 130.In addition, controller 120 also produces a function code to the function key 110 that should be pressed and sends and be stored into basic input-output system unit 140.Scan code wherein is the message that will notify the operating system unit 130 of back segment will carry out application program 131 wherein, and this scan code is by not used by the built-in function of most operating system.Function code then is a code of the application program that will carry out, and is the code that can discern for controller 120 and operating system unit 130.
When operating system unit 130 receives above-mentioned scan code, just can learn that a function will be activated.At this moment, operating system unit 130 can be by capturing function code in the basic input-output system unit 140, and so the application program 131 that the user will carry out just can be learnt in operating system unit 130, and start this execution action.
At this, lift a concrete example again, make this area tool know that usually the knowledgeable more can understand, and implement according to this.
When the user wants to transfer the volume of typhon, pushed the Fn key (for example being F10) that is used for transferring big volume, at this moment, controller 120 detects the F10 key and is pressed after the control signal that is transmitted, and has just produced one and has transferred the function code (for example being 01) of big volume to be stored in the basic input-output system unit 140.And the one group of scan code that produces comes notifying operation system unit 130 to carry out the function of transferring big volume.130 of operating system unit capture function code by basic input-output system unit 140 after having received this group scan code, and according to function code (this example is 01), carry out the action of transferring big volume.
Then, when the user wants to turn the volume of loudspeaker down, pushed the Fn key (for example being F9) that is used for turning down volume, at this moment, controller 120 detects the F9 key and is pressed after the control signal that is transmitted, and has just produced a function code (for example being 02) of turning volume down and has been stored in the basic input-output system unit 140.And the one group of scan code that produces comes notifying operation system unit 130 to carry out the function of turning volume down.130 of operating system unit capture function code by basic input-output system unit 140 after having received this group scan code, and according to function code (this example is 02), carry out the action of turning volume down.
Be not difficult in the start example by above-mentioned computer apparatus 100 to find that 120 of controllers have wherein used one group scan code, just can realize carrying out a plurality of functions.Effectively eliminate because of the keyboard scancode situation of conflicting too much that produce with built-in function operating system.
Below please refer to Fig. 2, Fig. 2 illustrates the synoptic diagram of another embodiment of computer apparatus of the present invention.In the computer apparatus 200 that Fig. 2 illustrates, comprise CPU (central processing unit) 210, chipset 220, storer 230, basic input-output system unit 240, hard disk 250 and function key 260.Chipset 220 wherein is made of north bridge chips 221 and South Bridge chip 222, and operating system unit 251 is stored in the hard disk 251.
When the user will use preset function at computer apparatus 200, just the pressing function key 260.This function key 260 is set on the keyboard (not illustrating) usually, can certainly be arranged on other the input peripheral equipment of computer apparatus 200 (for example mouse, touch control screen etc.).And South Bridge chip 222 detects the control signal that is pressed and is transmitted of function key 260, just produces and send scan code to operating system unit 251, and produces function code and be stored in basic input-output system unit 240.Operating system unit 251 can be by reading stored just now function code after receiving this scan code in the basic input-output system unit 240, and carry out relevant application program according to this function code.
Below please refer to Fig. 3, Fig. 3 illustrates the synoptic diagram of function activating method one embodiment of computer apparatus of the present invention.Its step comprises: at first, and the press condition of measuring ability key (S310), and when detecting function key and be pressed, produce corresponding a function code and a fixing scan code (S320), and store the function code that is produced.At last, again according to scan code receiving function sign indicating number, and according to the function code execution corresponding programs (S330) that is received.
Below will further propose an embodiment and be illustrated, more can understand this method so that this area tool is known the knowledgeable usually at the function activating method of above-mentioned computer apparatus.
Please refer to Fig. 3 (and please simultaneously with reference to Fig. 1), Fig. 3 illustrates the synoptic diagram of another embodiment of the function activating method of computer apparatus of the present invention.The step of this embodiment comprises: when the user will use correlation function, just push corresponding function key (S410) on the keyboard 110.At this moment, controller 120 detect function key be pressed and send the scan code sign indicating number to operating system unit 130 and the sending function sign indicating number to basic input-output system unit 140 (S420).And application program module 130 is after receiving scan code, and just by basic input-output system unit 140 read functions sign indicating numbers (S430), and the application program 131 in operating system unit 130 is carried out the defined functions of this function code (S440).
In sum, the present invention utilizes the scan code of the controller reception keyboard function key in the computer apparatus, and converting to a fixing scan code and corresponding function code of general carried out the action that starts function.Make the actual transmissions only to need one group, effectively avoided the increase of the keyboard scancode that causes because of the increase of function key, and then eliminated function key and the conflicting problem of operating system to the keyboard scancode of operating system and application program module.
Though the present invention discloses as above with preferred embodiment; right its is not in order to qualification the present invention, any those skilled in the art, without departing from the spirit and scope of the present invention; when can doing a little modification and perfect, so protection scope of the present invention is when with being as the criterion that claims were defined.
