Uninzi lwabantu luhlangabezana neengxaki ezahlukeneyo xa ufaka kunye nokulungisa ukungabonakali kokubonisa i-LED. Xa benxibelelana nofakelo olubonakalayo lwe-LED kunye nokulungisa ingxaki, uninzi lwabenzi be-LED bonisa ukuba abanayo imiyalelo, ke abasebenzisi banobunzima, andazi ukuba ukhe waqubisana nale mibuzo ilandelayo? Ukuba awukwazi ukuyilayisha, isikrini esimnyama, isikrini esimnyama, njl., Uyazibuza ukuba yintoni unobangela?
Umbuzo 1: Isikrini sonke simnyama
1. Nceda uqinisekise ukuba zonke izixhobo zekhompyutha kubandakanya inkqubo yolawulo inikwe amandla ngokufanelekileyo. (+ 5V, musa ukubuyela umva, qhagamshela ngokungalunganga)
2. Jonga kwaye uqinisekise ngokuphindaphindiweyo ukuba ingaba ikhebula le-serial elisetyenziselwa ukuqhagamshela kwisilawuli likhululekile okanye cha. (Ukuba iba mnyama ngexesha lenkqubo yokulayisha, inokubangelwa sesi sizathu, oko kukuthi, umgca wonxibelelwano uphazamisekile ngenxa yokukhululeka komtya wonxibelelwano ngexesha lenkqubo yonxibelelwano, ke isikrini siba mnyama, kwaye isikrini asikho ishukunyisiwe, kwaye umgca awunakukhululwa. Nceda ujonge, kubaluleke kakhulu ukusombulula ingxaki ngokukhawuleza.)
3. Jonga kwaye uqinisekise ukuba ngaba iscreen se-LED kunye nebhodi yokuhambisa ye-HUB iqhagamshelwe kwikhadi lolawulo eliphambili lixhumekile kwaye lifakiwe.
Umbuzo 2: Isikrini siyatshintsha okanye siqaqambe
Emva kokudibanisa umlawuli wescreen kwikhompyuter kunye nebhodi yokuhambisa ye-HUB kunye nescreen, kuya kufuneka unikeze + i-5V amandla kumlawuli ukuyenza isebenze ngokufanelekileyo (kule meko, musa ukunxibelelana ngqo ne-220V). Ngomzuzu wokuvula amandla, kuyakubakho imizuzwana embalwa yemigca eqaqambileyo okanye "isikrini esimnyama" kwiscreen. Umgca oqaqambileyo okanye "isikrini esimnyama" yinto eqhelekileyo yovavanyo, ekhumbuza umsebenzisi ukuba isikrini siza kuqala ukwenza umsebenzi oqhelekileyo. Kwimizuzwana emi-2, le nto isuswa ngokuzenzekelayo kwaye isikrini singena kwimeko yesiqhelo yokusebenza.
Umbuzo 3: Isikrini sonke sebhodi yeyunithi asiqaqambile okanye simnyama
1. Jonga ujonge ukuba ngaba uqhagamshelo lwentambo yombane, intambo engama-26P phakathi kweebhodi zeeyunithi, kunye nesibonisi semodyuli yamandla ziqhelekile.
2. Sebenzisa i-multimeter ukulinganisa umbane oqhelekileyo webhodi yeyunithi, emva koko ulinganise ukuba ngaba umbane wombane wemodyuli yamandla uqhelekile na. Ukuba akunjalo, kugwetywa ukuba imodyuli yamandla imbi.
3. Linganisa umbane wemodyuli yamandla usezantsi, lungelelanisa uhlengahlengiso oluhle (uhlengahlengiso oluhle lwemodyuli yamandla kufutshane nesibane sesikhombisi) ukwenza umbane ufikelele kumgangatho.
Umbuzo 4: Awunakho ukulayisha okanye ukunxibelelana
Isisombululo: Ngokwezizathu zidweliswe ngezantsi, umsebenzi uthelekiswa
1. Qinisekisa ukuba izixhobo zolawulo zisebenza ngokufanelekileyo. (+ 5V)
2. Jonga ukuba intambo yesiriyeli esetyenziselwa ukuqhagamshela kwisilawuli yintambo ethe ngqo, hayi intambo yecrossover.
3. Jonga kwaye uqinisekise ukuba intambo yezibuko le-serial ihambile kwaye akukho nto ikhululekileyo okanye iwe kwiziphelo zombini.
4. Thelekisa isoftware yolawulo lwesikrini se-LED kunye nekhadi lolawulo elikhethwe nguwe ukukhetha imodeli echanekileyo yemveliso, indlela echanekileyo yokuhambisa, inombolo yezibuko elichanekileyo, inqanaba lothumelo lotshintshiselwano oluchanekileyo kwaye usete ngokuchanekileyo ulawulo ngokwe-DIP switch diagram enikiweyo kwisoftware. Idilesi encinci kunye nenqanaba lokudluliswa kweedilesi kwizixhobo zenkqubo.
5. Jonga ukuba ngaba ikepusi yokutsiba ikhululekile okanye icinyiwe; ukuba ikepusi yokutsiba ayikhululekanga, nceda uqiniseke ukuba ikepusi yokutsiba ikwicala elifanelekileyo.
6. Ukuba itshekhi kunye nolungiso olungasentla alulayishi, nceda sebenzisa imultimeter ukulinganisa ukuba ngaba uthotho lwezibuko lwekhompyuter oluxhunyiwe okanye lwezixhobo zolawulo zonakele ukuqinisekisa ukuba kufuneka zibuyiselwe kumenzi wekhompyuter okanye inkqubo yolawulo inzima . Ukuhanjiswa komzimba nako kufunyenwe.
Ngexesha lofakelo kunye nokulungisa umboniso obonakalayo we-LED, umfaki kufuneka asebenze ngokulandelelana kovavanyo lokufaka ukuthintela iingxaki ezinje ngomonakalo kwiscreen. Ukuba uhlangabezana neengxaki zobuchwephesha, ungaqhagamshelana nengcali ekufumaneni isikhokelo sakho. Ndihlala ndazi ngakumbi malunga nolondolozo lwembonakalo ebonakalayo ye-LED, kwaye ndiza kuba lula xa ndinempazamo kwixa elizayo.
