FAQ
Q: Dab tsi yog Qhov Ob-Digit Xya Segment LED?
A: Ib tug Ob-Digit Xya Segment LED zaub muaj ob pawg ntawm xya tus neeg LED ntu, npaj los tso saib cov lej (0-9). Txhua tus lej tuaj yeem tswj tau los qhia tus lej los ntawm kev teeb pom kev tshwj xeeb, thiab ob tus lej siv los tso saib ob tus lej.
Q: Ob tug lej xya ntu LED ua haujlwm li cas?
A: Ob tug lej xya ntu LED zaub ua haujlwm los ntawm kev xa cov ntu tshwj xeeb ntawm txhua tus lej los ua cov lej. Txhua tus lej yog sawv cev los ntawm 7 ntu, thiab kev sib xyaw ntawm cov ntu no tuaj yeem tso tawm ib tus lej ntawm 0 mus rau 9. Ob tus lej yog tswj hwm ib tus zuj zus, feem ntau yog los ntawm multiplexing.
Q: Dab tsi yog daim ntawv thov ntawm Ob-Digit Xya Segment LED zaub?
A: Ob-digit Xya Segment LED zaub yog feem ntau siv rau hauv cov ntawv thov uas yuav tsum tau tso tawm ob tug lej yog qhov tsim nyog, xws li hauv cov moos, cov txee, voltmeters, ntsuas kub, thiab lwm yam khoom siv uas yuav tsum tau nyeem cov lej.
Q: Yuav ua li cas yog cov ntu ntawm Ob-Digit Xya Segment LED tswj?
A: Txhua ntu ntawm ob-tus lej xya ntu LED yog tswj los ntawm kev siv qhov hluav taws xob rau nws cov anode lossis cathode (nyob ntawm seb cov zaub yog cov anode lossis cov cathode). Tus maub los lossis microcontroller tsav lub LEDs los ntawm kev hloov ntawm cov ntu tsim nyog los ua tus lej xav tau.
Q: Dab tsi yog qhov txawv ntawm cov anode thiab ntau cathode Ob-Digit Xya Segment LEDs?
A: Nyob rau hauv ib qho anode Ob-Digit Xya Segment LED, cov anodes ntawm tag nrho cov ntu txuas nrog ib tus pin, thiab cov lej teeb tsa los ntawm kev siv lub zog qis rau cov cathodes sib xws. Nyob rau hauv ib qho cathode zaub, cov cathodes ntawm tag nrho cov ntu txuas nrog ib tus pin sib xws, thiab cov lej teeb tsa los ntawm kev siv hluav taws xob siab rau cov anodes sib thooj.
