Abantu abaningi bahlangabezana nezinkinga ezahlukahlukene lapho befaka noma benza iphutha ekubonisweni kwe-LED okusobala. Lapho bexhumana nokufakwa kwe-LED okusobala nokususa iphutha, abakhiqizi abaningi be-LED abanayo imiyalo, ngakho-ke abasebenzisi bonke baxakile, angazi noma wake wahlangabezana nale mibuzo elandelayo? Uma ungakwazi ukuyilayisha, isikrini esilufifi, isikrini esimnyama, njll., Uyazibuza ukuthi yini imbangela?
Umbuzo 1: Isikrini sonke simnyama
1. Sicela uqinisekise ukuthi yonke i-hardware kufaka phakathi uhlelo lokulawula inikwe amandla ngendlela efanele. (+ 5V, ungaguquli, xhuma ngokungalungile)
2. Hlola futhi uqinisekise kaninginingi ukuthi ngabe ikhebula le-serial elisetshenziselwe ukuxhuma kwisilawuli likhululekile noma cha. (Uma kuba mnyama ngesikhathi senqubo yokulayisha, kungenzeka kubangelwa yilesi sizathu, okungukuthi, ulayini wezokuxhumana uphazamisekile ngenxa yokuxegisa kolayini wokuxhumana ngesikhathi senqubo yokuxhumana, ngakho-ke isikrini siba mnyama, futhi isikrini ihanjisiwe, futhi umugqa awukwazi ukuxegiswa. Uyacelwa ukuthi ubheke, kubaluleke kakhulu ukuxazulula inkinga ngokushesha.)
3. Hlola bese uqinisekisa ukuthi ngabe isikrini se-LED esixhunyiwe nebhodi lokusabalalisa le-HUB lixhunywe ekhadini eliyinhloko lokulawula lixhunywe ngokuqinile futhi lifakiwe.
Umbuzo 2: Isikrini siyashintsha noma sikhanya
Ngemuva kokuxhuma isilawuli sesikrini kukhompyutha kanye nebhodi lokusabalalisa le-HUB nesikrini, udinga ukunikeza + 5V amandla kusilawuli ukuze sisebenze kahle (kulokhu, ungaxhumi ngqo ku-220V). Ngesikhathi sokuvula amandla, kuzoba nemizuzwana embalwa yolayini abagqamile noma "isibuko esilufifi" esikrinini. Umugqa ogqamile noma "isikrini esilufifi" kuyinto ejwayelekile yokuhlola, ekhumbuza umsebenzisi ukuthi isikrini sesizoqala umsebenzi ojwayelekile. Ngemizuzwana emi-2, lo mkhuba ususwa ngokuzenzakalela futhi isikrini singena esimweni esivamile sokusebenza.
Umbuzo 3: Isikrini sonke sebhodi leyunithi asikhanyi noma simnyama
1. Bheka ngokubuka ukuthi ngabe ikhebula lokuxhuma ugesi, ikhebula le-26P phakathi kwamabhodi amayunithi, nenkomba yemodyuli yamandla kuvamile yini.
2. Sebenzisa i-multimeter ukukala i-voltage ejwayelekile yebhodi leyunithi, bese ulinganisa ukuthi ngabe ukuphuma kwamandla we-module yamandla kuvamile yini. Uma kungenjalo, kwahlulelwa ukuthi imodyuli yamandla ayilungile.
3. Linganisa i-voltage yemodyuli yamandla iphansi, lungisa ukulungiswa okuhle (ukulungiswa okuhle kwemodyuli yamandla eduze kwesibani senkomba) ukwenza i-voltage ifinyelele ezingeni.
Umbuzo 4: Ayikwazi ukulayisha noma ukuxhumana
Isixazululo: Ngokuya ngezizathu ezibalwe ngezansi, umsebenzi uqhathaniswa
1. Qinisekisa ukuthi i-hardware yesistimu yokulawula inikwe amandla ngendlela efanele. (+ 5V)
2. Bheka ukuthi ikhebula le-serial elisetshenziselwa ukuxhuma kwisilawuli liyikhebula eliqonde ngqo, hhayi ikhebula le-crossover.
3. Hlola bese uqinisekisa ukuthi ikhebula le-serial port liqinile futhi akukho okuxekethile noma okuwa emaphethelweni womabili.
4. Qhathanisa isoftware yokulawulwa kwesikrini se-LED kanye nekhadi lokulawula elikhethwe nguwe ukukhetha imodeli yomkhiqizo elungile, imodi yokudlulisa efanele, inombolo ethekwini yenombolo eyi-serial, isilinganiso esifanele sokudluliswa kwe-serial futhi usethe kahle ukulawula ngokuya ngomdwebo wokushintsha we-DIP onikeziwe ku-software. Ikheli lokudlulisa kanye nesilinganiso sokudluliswa kwe-serial ku-hardware yohlelo
5. Bheka ukuthi ikepisi leqaqa likhululekile noma livaliwe; uma ikepisi leqaqa lingakhululekile, sicela uqinisekise ukuthi ikepisi leqawe lisendaweni efanele.
6. Uma isheke elingenhla nokulungiswa kusalokhu kungalayishwa, sicela usebenzise i-multimeter ukukala ukuthi ngabe imbobo ye-serial yekhompyutha exhunyiwe noma i-hardware yesistimu yonakele yini ukuqinisekisa ukuthi kufanele ibuyiselwe kumkhiqizi wekhompyutha noma uhlelo lokulawula lunzima . Ukulethwa komzimba nakho kutholakele.
Ngesikhathi sokufakwa nokususa iphutha ekubonisweni kwe-LED okusobala, isifaki sidinga ukusebenza ngokulandelana kokuhlolwa kokufaka okujwayelekile ukugwema izinkinga ezinjengokonakala esikrinini. Uma uhlangabezana nezinkinga zobuchwepheshe, ungaxhumana nochwepheshe onguchwepheshe ukuze akuthole. Imvamisa ngazi okuningi ngemininingwane yesondlo yezinye izibonisi ze-LED ezisobala, futhi ngizoba mnandi kakhudlwana lapho ngizoba nephutha ngokuzayo.
