Ngokuthuthuka okusheshayo kwemboni yokubonisa i-LED, isidingo semakethe yekhadi lokulawula isibonisi se-LED siyakhula, futhi ikhadi lokulawula i-LED elingenantambo lingahlangabezana kahle nezidingo zamakhasimende ekuphathweni okuhlangene kanye nemakethe yokudlulisa iqoqo. Isibonelo, isikrini se-poster LED, isibonisi se-LED esiphezulu setekisi, isibonisi se-LED yesigxobo esikhanyayo nesidlali esiholayo. Ukuphatha okulula kanye nekhadi lokulawula isibonisi esiholwa ngokulungiswa kalula kuyisinqumo esihle kubasebenzisi. Ukuze ugweme ukulahlekelwa okungadingekile, abasebenzisi kufanele banake amaphuzu alandelayo lapho besebenzisa ikhadi lokulawula.
Okokuqala, faka ikhadi lokulawula endaweni eyomile futhi ezinzile. Izinga lokushisa elidlulele kanye nomswakama kanye nemvelo enothuli kuyingozi kakhulu ekhadini lokulawula.
Okwesibili, kwenqatshelwe ngokuphelele ukuxhuma nokukhipha imbobo ye-serial ngaphandle kokwehluleka kwamandla ukuvimbela ukusebenza okungalungile ekulimazeni imbobo ye-serial yekhompyutha kanye nembobo ye-serial yekhadi lokulawula.
Okwesithathu, kwenqatshelwe ngokuphelele ukulungisa i-voltage yokufaka yekhadi lokulawula lapho uhlelo lusebenza, ukuze ugweme ukulimala kwe-serial port yekhompyutha kanye ne-serial port yekhadi lokulawula ngenxa yokulungiswa okungalungile kanye ne-voltage ngokweqile. I-voltage evamile yokusebenza yekhadi lokulawula yi-5V. Lapho ulungisa amandla kagesi, ikhadi lokulawula kufanele lisuswe futhi lilungiswe kancane ngemitha yendawo yonke.
Okwesibili, kwenqatshelwe ngokuphelele ukufinyeza itheminali yaphansi yekhadi lokulawula ngohlaka lokubonisa oluholayo, ngaphandle kwalokho, uma ugesi omile unqwabelana, kulula ukulimaza imbobo ye-serial yekhompuyutha kanye nembobo ye-serial yekhadi lokulawula, okuholela ekuxhumaneni okungazinzile. Uma ugesi omile unzima, ikhadi lokulawula neskrini esiholayo kuzoshiswa. Ngakho-ke, uma ibanga lokulawula isikrini eliholwayo lilide, sincoma ukuthi abasebenzisi kumele basebenzise isihlukanisi sembobo se-serial ukugwema ukulimala kwembobo ye-serial yekhompuyutha kanye nochungechunge lwekhadi lokulawula ngenxa yezindawo ezinokhahlo ezifana nezihibe zaphansi, ama-surges, ukushaywa kombani kanye nembobo yolayini yokuxhuma. .
Okwesihlanu, kuyadingeka ukuqinisekisa ukuxhumana okulungile phakathi kwekhadi lokulawula kanye nembobo ye-serial yekhompiyutha ukuze ugweme ukulimala kwembobo ye-serial yekhadi lokulawula kanye nembobo ye-serial yekhompyutha ngenxa yezimpawu zokufaka ezingalungile.
Ikhadi lokulawula isibonisi se-LED liwumgogodla we-eq
