Izinkinga Ezivamile Zephutha Nezixazululo Zamamojula Wemithombo Yokukhanya Yephuzu Le-LED

Eminyakeni yamuva, ukukhanya kwe-landscape yasekhaya kuye kwathuthuka ngokushesha. Ukukhanyisa kokukhanyisa kwezwe okuhlobisa kwangaphandle ngenjongo yokuhlobisa izindawo zasemadolobheni nokukhangisa kwezohwebo kuyaziswa futhi kusetshenziswe kokuningi. Ingasetshenziselwa ukuhlobisa umhlobiso, futhi ingahlanganiswa ibe imigqa yokukhanya kwe-contour. Kodwa imithombo yokukhanya yamachashazi e-LED ihlale ihlangabezana nokwehluleka okuningi noma okuncane ekusebenziseni kwangempela. Ngezansi, ngizokwethula ezinye zezinto ezivamile zephutha kanye nezixazululo zokuhlaziya ngokuningiliziwe. Iphutha 1: Ngemva kokunikezelwa kwamandla, ukukhanya kwephutha kwesilawuli (ERROR) kuyabanyaza, umthombo wokukhanya awukhanyi, futhi akukho okuphumayo komphumela wokugqwayiza? Impendulo: Lesi simo ngokuvamile kungenxa yokuthi isilawuli asilifundi kahle ikhadi, futhi uhlelo oluvumelekile lokulawula alukhiqizi. Isizathu singaba: Ikhadi le-1.SD alinalutho, alikho ifayela elisebenzayo Iphutha legama lefayela lohlelo lwekhadi le-2.Ikhadi le-SD Ikhadi le-3.Ikhadi le-3.Ikhadi lekhadi le-3.Ikhadi le-SDIkhadi le-3.Ikhadi le-SD Ukufometha njengoba kudingeka ngaphambi kokukopisha ifayela lomphumela 4. Ifayela eliwumphumela ne-chip yesibani, imodeli yesilawuli ekhadini le-SD akufani, udinga ukuxhumana nomkhiqizi ukuze wenze kabusha ifayela lomphumela 5. Ngemva kokufaka esikhundleni sekhadi le-SD elisha Amathuba amabi anephutha: Ngemva kokunikezelwa kwamandla, inkomba yesilawuli ijwayelekile, kukhona okukhipha isignali, kodwa imojula yomthombo wokukhanya wephoyinti le-LED ayinalo ushintsho lomthelela? Impendulo: Kulokhu, ngokuvamile kuba nezizathu ezilandelayo: 1. Hlola ukuthi isignali nesilawuli sezibani kuxhumeke kahle yini. 2. Isignali yesibani sokulawula yangaphandle inokuthuthuka/ngaphandle kwendawo, hlola ukuthi ingabe isignali yokulawula evela kusiginali yokukhanya okungaphambili End ngo-3. Hlola ukuthi imodeli ikhethiwe yini uma wenza ifayela eliwumphumela ekhadini le-SD*. I-LeD yayihambisana ne-chip esetshenziswa kumalambu amanje. 4. Isibani nesilawuli kufanele kube ndawonye, ​​okungukuthi, umugqa ophansi wesibani kufanele ube umugqa ophansi. I-GND ixhunywe iphutha lesithathu: Ngemva kokuba isilawuli nesibani sixhunyiwe, umphumela uyashintsha, kodwa izibani zikhanya, futhi inkomba yesilawuli ibonisa evamile? A: Umugqa ophansi phakathi kwesilawuli nesibani awuxhunyiwe 2. I-Lantern I-voltage yokuphakelwa kwamandla engaphansi kuka-3. Umthelela ekhadini le-SD awulungile. I-chip yesibani kanye ne-chip yezibani zangempela lapho umphumela usuqedile. 4. Ibanga ukusuka kusilawuli ukuya kusibani sokuqala (ibanga > Amamitha angu-10), ukudluliswa kwesignali akuzinzile Ukwehluleka kwe-4: Ngemva kokusetshenziswa kwamandla, isilawuli kanye nengxenye yangaphambili yesibani isebenza ngokujwayelekile. Isibani asivamile ngemva kokuba isibani esithile siqale? Impendulo: Lesi simo ngokuvamile yisibani esingemuva kwezibani ezihlulekile ukwamukela isignali ngokujwayelekile. Izizathu ngokuvamile zimi kanje: 1. Ukwehluleka kwezibani ngazinye ku-IC IC noma ulayini wesiginali wonakaliswa ngaphambi nangemuva kokukhanya. Isibani singabhalwa kancane lapho kubhalwa uhlelo (isibonelo, izingcezu ezingu-9,000 empeleni zisetshenziswa, futhi zingu-8,000 kuphela ezibhalwe ohlelweni). Ngale ndlela, awukho umphumela wokugqwayiza engxenyeni yokugcina. : Ngemva kokukhanyisa, isilawuli sisebenza ngokujwayelekile, isibani asijwayelekile, futhi umphumela wesikrini sevidiyo uhlukile? Impendulo: Lesi simo sibangelwa ukungahambisani nomyalelo wokufaka izibani nemiklamo. Udinga ukulungisa ukulandelana nendawo yesibani ngokuya ngomdwebo oklanyelwe wokugibela, noma faka ukuhlelwa kwesibani sokufaka sangempela. Iya kukhompyutha ukuze uphinde ulungiselele ukuhluleka kohlelo 6: Ngemva kokuba amandla edlulisiwe, imojula yomthombo wokukhanya wephoyinti le-LED ingashintsha ngokujwayelekile, kodwa kunemithombo ethile yokukhanya ebonisa umbala ohlukile komunye? Impendulo: Lesi simo ngokuvamile sibangelwa ukulimala kwesibani R, G, no-B chip, okubangela ukuboniswa kombala wokuntuleka. Udinga kuphela ukufaka esikhundleni senkinga ngephoyinti lokukhanya. Impendulo Yempambana-mgwaqo: 1. Okokuqala qinisekisa ukuthi iswishi yokuvikela eseceleni kwekhadi le-SD ivuliwe yini. Isiqondiso sokuvula inaliti yegolide yekhadi le-SD. 2. Ilokhi yokuvikela ivuliwe njengoba kudingeka, kodwa namanje ayikwazi ukufometha. Uma idivayisi iphukile, sicela ufake isifundi sekhadi le-SD 3. Uma ukusebenza okungenhla kungakakwazi ukuxazulula inkinga yokufometha, sicela ushintshe ikhadi le-SD uphinde uhlole
