Izibonisi zezingxenye ze-Common Anode ne-Common Cathode 7

Izinhlelo zokusebenza zokuboniswa kwezingxenye ezingu-7

Siyini Isibonisi Sezingxenye Eziyisi-7?

Isibonisi esinezingxenye eziyisi-7 iyinsiza ye-elekthronikhi esetshenziselwa ukubonisa izinombolo zedesimali namanye ama-alfabhethi. Iqukethe amasegimenti ayisikhombisa ahlelwe ngendlela engunxande, ngayinye engakhanyiswa ngokuzimela ukwenza izinombolo nezinye izinhlamvu. Lawa masegimenti ngokuvamile alebulwe njengokuthi 'a' ukuya ku-'g', anechashazi lokuzikhethela (dp) lamaphoyinti edesimali.

Ukwakheka kwesibonisi esinezingxenye eziyisi-7

Isibonisi esijwayelekile samasegimenti angu-7 sihlanganisa amasegimenti e-LED ayisikhombisa kanye nesegimenti eyisishiyagalombili engakhethwa yephoyinti ledesimali. Ingxenye ngayinye ilawulwa ngokwehlukana, okuvumela ukumelwa kwezinombolo ukusuka ku-0 kuye ku-9 kanye nezinhlamvu ezithile zama-alfabhethi.

Izinhlobo zokuboniswa kwezigaba ezingu-7

1. I-Common Anode (CA): Emibukisweni evamile ye-anode, wonke ama-anode (amatheminali amahle) ezingxenyeni ze-LED axhunywe ndawonye, ​​futhi ama-cathode angawodwana (ama-terminal negative) axhunywe kumjikelezo wokulawula.
2. I-Common Cathode (CC): Emibukisweni evamile ye-cathode, wonke ama-cathode (ama-terminals angalungile) ezingxenyeni ze-LED axhunywe ndawonye, ​​futhi i-anode ngayinye (ama-terminals positive) axhunywe kumjikelezo wokulawula.

Ukukhetha Phakathi kwe-Common Anode ne-Common Cathode

Ukukhetha uhlobo olulungile lwesibonisi sezingxenye ezingu-7—i-anode evamile (CA) noma i-cathode evamile (CC)—kuncike kakhulu ekwakhiweni kwesifunda sakho nendlela yokushayela. Ngenkathi bobabili benza umsebenzi ofanayo oyisisekelo, ukuqonda kwabo kwezintambo nokuhambisana namasekhethi okulawula kuyahluka:

• I-Common Anode (CA):
  Wonke ama-anode aboshwe ku-voltage eqondile, futhi ingxenye ngayinye icushiwe ngokudonsa i-cathode yayo iphansi (phansi). Lokhu kulungiselelwa kuvame ukuncanyelwa uma kusetshenziswa izishayeli ezishintshayo eziseceleni eliphansi njengama-transistors noma okuphumayo kweqoqo elivulekile.
• I-Common Cathode (CC):
  Wonke ama-cathode aboshelwe phansi, futhi izingxenye zivulwa ngokufaka i-voltage eqondile kuma-anode awo. Lokhu kubenza kube lula ukusebenzisana nama-microcontroller noma ama-ICs omshayeli athola okwamanje kumaphini abo okukhiphayo.

Izinyathelo ezibalulekile lapho ukhetha:

1. Ukushayela Ukuhambisana Kwesekethe - Uma umklamo wakho usebenzisa abashayeli abaphansi, i-CA ivame ukuba lula; kubashayeli abaseceleni okuphezulu noma ukuphuma okuqondile kwe-MCU, i-CC ingase ibe lula.
2. Ukusebenza kwamandla - Zombili izinhlobo zisebenzisa amandla afanayo, kodwa i-CC ngezinye izikhathi inganciphisa ukubalwa kwezingxenye kumasekhethi alula.
3. Ukutholakala Kwengxenye - Amanye amamojula wokubonisa noma ama-IC omshayeli enzelwe uhlobo oluthile, ngakho ukutholakala kuchungechunge lwakho lokunikezela kungase kube nomthelela ekukhetheni kwakho.
4. Umongo Wokusebenza - Ngezibonisi ezinama-multiplexed noma izibalo ezinamadijithi aphezulu, i-CA ivame ukukhethwa ngenxa yokuhambisana kwayo nama-IC omshayeli asebenzayo.

Ngokuqonda lo mehluko, abaklami bangenza ukukhetha okunolwazi oluqinisekisa ukuhlanganiswa okushelelayo nesakhiwo sabo se-PCB, idizayini yamandla, kanye nokucabanga kokulawula. Lesi sinqumo sakha isisekelo sezindlela zokushayela, izifunda zokuvikela, namasu athuthukile ahlolisiswa ezigabeni ezilandelayo.

Isebenza Kanjani Izibonisi Zezingxenye Eziyisi-7

Ukusebenza kwesibonisi sezingxenye ezingu-7 kusekelwe ekukhanyeni kwamasegimenti ngamanye. Ingxenye ngayinye iyi-LED, futhi ngokukhanyisa ngokukhetha lezi zingxenye, izinombolo ezahlukene nezinhlamvu zingaboniswa.

Ukulawula Ingxenye

Isegimenti ngayinye kusibonisi samasegimenti angu-7 ingavulwa noma ivalwe ngokuzimela. Ngokulawula inhlanganisela yezingxenye ezikhanyisiwe, izinombolo nezinhlamvu ezihlukahlukene zingakhiwa. Ngokwesibonelo:

• Inombolo '8' yakheka ngokukhanyisa wonke amasegimenti ayisikhombisa.
• Inombolo '1' yakhiwa ngokukhanyisa amasegimenti 'b' kanye 'no'c' kuphela.
