Embodiment
Please with reference to Fig. 1, it illustrates a kind of functional-block diagram with electronic installation of CD drive according to an embodiment of the present invention.Electronic installation with CD drive its embedded controller (Embedded Controller, EC) receive press move back the sheet key and produce move back the sheet signal time, just trigger its CD drive and move back sheet by embedded controller.Electronic installation 100 with CD drive comprises a CD drive 110, and moves back a sheet key 120 and an embedded controller 130.Wherein, CD drive 110 can be the CD drive of inhalation type optical disk driver, pellet type CD drive, CD CD drive, DVD CD drive, Blu-ray Disc driver, HD DVD CD drive or other kinds.Moving back sheet key 120 can be in a plurality of shortcuts (Hot Key) of a keyboard of the electronic installation 100 with CD drive one, the Macintosh of a plurality of buttons of keyboard or has in a plurality of medium buttons (Media Button) of electronic installation 100 of CD drive.For instance, can use F1+F2 as moving back the Macintosh that the sheet key is used.Yet, in other embodiments, can use other different keys combinations, as moving back the Macintosh that the sheet key is used.Embedded controller 130 can be KBC (Keyboard Controller, KBC) or other embedded controllers.
(General Purpose Input/Output, GPIO) pin 131 electrically connects with data transmission pin (moving back the sheet pin) 112 in one general input and output of embedded controller 130.Wherein, can general input and output pin 131 be electrically connected to the data transmission interface Connection Block in order to affixed CD drive 110, to electrically connect with data transmission pin (moving back the sheet pin) 112.In addition, embedded controller 130 with move back sheet key 120 and connect.Wherein, When utilizing the conduct of medium button to move back sheet key 120; Move back sheet key 120 can pass through internal integrated circuit (Inter-Integrated Circuit, I2C) bus, System Management Bus (System Management Bus, SMBus) or other buses and embedded controller 130 connect.
In the practical operation, moving back sheet key 120 when touched, moving back sheet key 120 and produce one and move back the sheet signal, and will move back the sheet signal and be sent to embedded controller 130.Wherein, move back the sheet signal that moves back that sheet key 120 produced and can be a keyboard scancode (scancode), to simulate the shortcut of a keyboard.In addition, utilizing the medium button when moving back sheet key 120, moving back the sheet signal that moves back that sheet key 120 produced and can be the instruction of internal integrate circuit bus, the instruction of System Management Bus or the instruction of other buses.
Receive when moving back the sheet signal that at embedded controller 130 embedded controller 130 moves back sheet from the data transmission pin (moving back the sheet pin) 112 of general input and output pin 131 output trigger pip to CD drives 110 to trigger CD drive 110.CD drive 110 can be confirmed earlier its state whether for moving back the sheet state when receiving trigger pip, and does not only move back sheet when moving back the sheet state at CD drive 110.Thus, move back the panel that sheet key 120 just can not need be arranged at CD drive 110, and increase the dirigibility on electronic installation 100 mechanism design with CD drive.
Please with reference to Fig. 2, it illustrates the process flow diagram that moves back the sheet control method according to a kind of CD drive of another embodiment of the present invention.CD drive moves back the sheet control method and continue to receive push button signalling, and at push button signalling when moving back the sheet signal, the triggering CD drive moves back sheet.CD drive moves back sheet control method 200 and comprises following steps:
Continue to receive a push button signalling (step 210), and judge whether push button signalling is to move back sheet signal (step 220).Wherein, can continue to receive push button signalling (step 210) from a keyboard.When push button signalling is when keyboard receives, push button signalling is a keyboard scancode, and can by judging whether push button signalling is the keyboard scancode of corresponding quitting function, and judges that whether push button signalling is for moving back sheet signal (step 220).
In addition, also can pass through bus,, continue to receive push button signalling (step 210) from least one medium button like internal integrate circuit bus, System Management Bus or other buses.When push button signalling be through bus when the medium button receives, can by judging whether push button signalling is the bus command of corresponding quitting function, and judge that whether push button signalling is for moving back sheet signal (step 220).
In step 230, when push button signalling when moving back the sheet signal, produce a trigger pip, like an one edge variable signal or a level variable signal, move back the sheet pin to one of a CD drive, move back sheet to trigger CD drive.Wherein, move back the data transmission interface that the sheet pin is a CD drive, as one in a plurality of data transmission pins of SATA series interfaces (comprising SATA interface, SATAII interface and other SATA interfaces), ide interface or other data transmission interfaces.In addition, also can be at the newly-increased pin of data transmission interface as moving back the sheet pin.CD drive can be the CD drive of inhalation type optical disk driver, pellet type CD drive, CD CD drive, DVD CD drive, Blu-ray Disc driver, HD DVD CD drive or other kinds.In addition, CD drive does not only move back sheet when moving back the sheet state at its state.Yet, when push button signalling not when moving back the sheet signal, continue to receive push button signalling (step 210).
Can know by the invention described above embodiment, use the present invention and have advantage.Move back the sheet key and can be arranged at the panel place in addition of CD drive, and increase the dirigibility in the electronic device mechanism design with CD drive.In addition, only need to drive CD drive and move back sheet, and do not need to install in order to move back the application program of sheet in addition by embedded controller.Thus, can not take the resource of operating system, and can avoid when the driving CD drive moves back sheet, influencing the resource of other program access operating systems.In addition, on hardware designs, only need make embedded controller be electrically connected to data transmission interface Connection Block in order to affixed CD drive.Then, upgrade the firmware of CD drive, and make CD drive to drive CD drive and to move back sheet, and need not change original hardware structure according to the trigger pip that embedded controller produced.In addition, also can move back the sheet pin,, move back sheet to trigger CD drive in order to receive the trigger pip that embedded controller produced at the data transmission interface newly-increased of CD drive.
Though the present invention with embodiment openly as above; Yet it is not in order to limit the present invention; Any those skilled in the art; Do not breaking away from the spirit and scope of the present invention, should do various changes and retouching, so protection scope of the present invention should be looked being as the criterion that the appending claims scope defined.
