USB stands rau Universal Serial Bus thiab yog ib qho kev sib txuas siv hauv computers. HID txhais tau tias Human Interface Device. Keyboard hais txog lub keyboard, thiab cable hais txog cable.
USB HID Keyboard Cable yog hais txog kev sib txuas ntawm cov keyboard uas ua raws li USB HID raws tu qauv, lossis lwm yam lus, cov keyboard uas sib txuas lus nrog tus tswv cuab ntawm lub USB cable. Nws txoj haujlwm yog tso cai rau cov keyboard sib txuas lus nrog lub khoos phis tawj, muaj PC, lossis cov kab ke sib txuas ntawm USB interface.
Qee zaum, lo lus USB HID keyboard cable tsis tsuas yog txhais tau tias tus qauv keyboard cable. Nws tseem tuaj yeem xa mus rau lub cuab yeej uas ua raws li cov keyboard. Piv txwv xws li barcode scanners, them nyiaj terminals, ruaj ntseg dongles, los yog kev loj hlob boards xws li Arduino los yog STM32. Cov khoom siv no nthuav tawm lawv tus kheej mus rau lub khoos phis tawj raws li cov keyboard thiab xa cov ntaub ntawv tib yam li cov keyboard nkag.
HID stands rau Human Interface Device Class. Nws yog cov cuab yeej siv hauv chav kawm uas tau teev tseg hauv USB qhov tshwj xeeb uas tsim cov khoom siv nkag li cas xws li cov keyboards, nas, game controllers, thiab barcode scanners sib txuas lus nrog tus tswv tsev. Ib qho txiaj ntsig tseem ceeb ntawm HID cov cuab yeej yog tias lawv tsis tas yuav muaj cov tsav tsheb ntxiv, txij li kev khiav hauj lwm xws li Windows, Linux, thiab macOS suav nrog ua - hauv HID kev txhawb nqa. HID pab kiag li lawm siv cov ntawv ceeb toom los txhais cov hom kev tawm tswv yim thiab cov ntaub ntawv tawm, tso cai rau tus tswv tsev kom paub txog hom ntaus ntawv.
Lub hauv paus ntsiab lus ua haujlwm ntawm USB HID keyboard yog raws li hauv qab no. Thaum tus yuam sij raug nias, lub microcontroller hauv cov keyboard pom qhov hloov pauv. Nws ces tsim ib daim ntawv qhia HID raws li USB HID raws tu qauv, piv txwv li qhia tias tus yuam sij A tau raug nias. Daim ntawv tshaj tawm no raug xa mus rau tus tswv tsev los ntawm USB HID interface. Lub operating system txhais cov ntawv tshaj tawm thiab hloov nws mus rau hauv qhov kev tshwm sim tawm tswv yim, xws li tso tawm tsab ntawv a ntawm qhov screen.
Cov xwm txheej ntawm daim ntawv thov muaj xws li cov qauv USB keyboards, barcode scanners uas tso tawm cov ntaub ntawv scanned raws li cov keyboard input, POS systems thiab daim npav nyeem ntawv uas ua raws li cov keyboard input, thiab embedded txoj kev loj hlob tej yaam num uas pab kiag li lawm xws li Arduino los yog STM32 ua raws li ib tug USB HID keyboard kom tau txais input commands.
