Iingxaki zeFault Common kunye nezisombululo ze-LED Point Light Sources Modules

Kwiminyaka yakutshanje, ukukhanya kwendawo yasekhaya kuphuhliswe ngokukhawuleza. Izibane zangaphandle zokuhombisa izibane zendalo ngenjongo yokuhombisa imihlaba yasezidolophini kunye neentengiso zentengiso zixatyiswa kwaye zisetyenziswa ngakumbi nangakumbi. Ingasetyenziselwa ukuhombisa umhlobiso, kwaye inokudibaniswa kwimigca ye-contour brilliance. Kodwa i-LED dot -point imithombo yokukhanya ihlala idibana nokungaphumeleli okungaphezulu okanye okuncinci ekusebenziseni okwenyani. Apha ngezantsi, ndiza kukwazisa ezinye zeempazamo eziqhelekileyo kunye nezisombululo zohlalutyo kuwe ngokweenkcukacha. Impazamo yoku-1: Emva kokuba amandla enziwe, isibane somlawuli (ERROR) siyadanyaza, umthombo wokukhanya awuqaqambi, kwaye akukho siphumo sesiphumo soopopayi? Impendulo: Le meko ngokuqhelekileyo ngenxa yokuba umlawuli akafundi ikhadi ngokuchanekileyo, kwaye inkqubo yokulawula esebenzayo ayiphumi. Isizathu sinokuba: Ikhadi le-1.SD lingenanto, akukho fayile ye-2.SD yekhadi lefayile yegama lefayile yephutha 3.Ikhadi lekhadi le-3.Ikhadi lekhadi le-3.Ikhadi lekhadi le-3.Ikhadi le-SD ikhadi le-3.SD Ukufomatha njengoko kufuneka phambi kokukopa ifayile yesiphumo 4. Ifayile yesiphumo kunye ne-chip yesibane, imodeli yomlawuli kwikhadi le-SD ayifani, kufuneka uqhagamshelane nomenzi ukuba uphinde wenze ifayile ye-5. Emva kokutshintshwa kwekhadi elitsha le-SD Amathuba amabi angalunganga: Emva kokuba amandla enziwe, isalathisi somlawuli siqhelekile, kukho ukuphuma kwesignali, kodwa imodyuli yomthombo wokukhanya we-LED ayinalo utshintsho lwesiphumo? Impendulo: Kule meko, kukho ezi zizathu zilandelayo ngokubanzi: 1. Khangela ukuba isignali kunye nomlawuli wezibane zixhunyiwe ngokuchanekileyo. 2. Isignali yesibane solawulo lwangaphandle inokuqhubela phambili / ngaphandle kwesalathiso, khangela ukuba isignali yokulawula ukusuka kwisiginali yokukhanya okungaphambili Ukuphela kwe-3. Jonga ukuba ngaba imodeli ekhethiweyo xa usenza ifayile yesiphumo kwikhadi le-SD*. I-LeD yayihambelana ne-chip esetyenziswe kwizibane zangoku. 4. Isibane kunye nomlawuli kufuneka zibe kunye, oko kukuthi, umgca womhlaba wesibane kufuneka ube ngumgca ophantsi. I-GND idibaniswe nesiphoso sesithathu: Emva kokuba umlawuli kunye nesibane zidibaniswe, umphumo uyatshintsha, kodwa izibane zikhanyisa, kwaye isalathisi somlawuli sibonisa eqhelekileyo? A: Umgca womhlaba phakathi komlawuli kunye nesibane awuxhunyiwe 2. ILantern Umbane wombane ongaphantsi kwe-3. Isiphumo kwikhadi le-SD alilunganga. I-chip yesibane kunye ne-chip yezibane zangempela xa umphumo wenziwa. 4. Umgama ukusuka kumlawuli ukuya kwisibane sokuqala (umgama > Iimitha ezili-10), ukuhanjiswa komqondiso akuzinzile Ukungaphumeleli kwe-4: Emva kokuba kusetyenziswe amandla, umlawuli kunye nenxalenye yangaphambili yesibane isebenza ngokuqhelekileyo. Isibane asiqhelekanga emva kokuba isibane esithile siqale? Impendulo: Le meko ngokuqhelekileyo isibane emva kwezibane ezisilele ukufumana umqondiso ngokuqhelekileyo. Izizathu zidla ngokuba ngolu hlobo lulandelayo: 1. Izibane zomntu ngamnye IC IC ukungaphumeleli okanye umgca wesignali wonakaliswe ngaphambi nangemva kokukhanya. Isibane sinokubhalwa ngaphantsi xa kubhalwa inkqubo (umzekelo, iziqwenga ze-9,000 zisetyenziswa ngokwenene, kwaye zi-8,000 kuphela ezibhaliweyo kwiprogram). Ngale ndlela, akukho siphumo soopopayi kwinxalenye yokugqibela. : Emva kombane, umlawuli usebenza ngokuqhelekileyo, isibane asiqhelekanga, kwaye umphumo weskrini sevidiyo uhlukile? Impendulo: Le meko ibangelwa ukungahambisani nomyalelo wokufaka izibane kunye nokuyila. Kufuneka ulungelelanise ukulandelelana kunye nendawo yesibane ngokomzobo wokukhwela owenziweyo, okanye faka ucwangciso lwesibane sofakelo lwangempela. Yiya kwikhompyuter ukuze uphinde ulungiselele ukusilela kwenkqubo 6: Emva kokuba umbane udlulile, imodyuli yomthombo wokukhanya we-LED inokutshintsha ngokuqhelekileyo, kodwa kukho imithombo ethile yokukhanya ebonisa umbala ohlukileyo kwezinye? Impendulo: Le meko ngokuqhelekileyo ibangelwa umonakalo wesibane se-R, G, kunye ne-B chip, ebangela ukubonakaliswa kokungabikho kombala. Udinga kuphela ukutshintsha ingxaki kwindawo yokukhanya. Impendulo yendlela-ndlela: 1. Okokuqala qinisekisa ukuba utshintshi lokukhusela kwicala lekhadi le-SD luvuliwe. Indlela yokuvula yinaliti yegolide yekhadi le-SD. 2. Isitshixo sokhuseleko sivulwe njengoko kufuneka, kodwa asikwazi ukufomatha. Ukuba isixhobo sophukile, nceda ubuyisele umfundi wekhadi le-SD 3. Ukuba umsebenzi ongentla awukakwazi ukusombulula ingxaki yokufomatha, nceda utshintshe ikhadi le-SD kwaye uphinde uvavanye
