Izintambo ze-LED ezitholakalayo phakamisa ibhentshimakhi ibe ileveli entsha ngokuphelele. Bakunikeza izinketho eziningi kanye nemiphumela emihle kakhulu yokukhanyisa njengokujaha ukugijima, ukufiphala okugelezayo, imikhondo ye-meteor, nokunye okuningi. Ungakwazi ngisho nokuklama imiphumela yakho yokukhanyisa ngesistimu yokulawula.
Kodwa kunezinhlobo eziningi zemichilo ye-LED elungisekayo kangangokuthi kunzima ngabantu ukuyihlukanisa ngendlela efanele. Ngokwesibonelo, into abantu abayibuza kakhulu uyini umehluko phakathi kwe-WS2811 ne-WS2812B.
Iyini i-WS2811?
I-WS2811 iwumugqa we-LED we-RGB okwazi ukubhekana kalula. Kusho ukuthi ungabonisa umbala ngamunye we-LED ngosizo lwesignali yolwazi. Ungathola lawa masignali ezindaweni ezimbalwa, njengephinikhodi yedijithali ebhodini le-Arduino noma isilawuli se-LED se-SPI RGB esifanele.
Kubalulekile ukwazi ukuthi lesi siginali yolwazi iwukushaya kwenhliziyo kwe-pulse-width-modulated (PWM). Into ebaluleke kakhulu okumele uyikhumbule yilokhu. Ukuguquguquka kobubanzi be-Pulse, noma i-PWM, yikho okunikeza ama-LED amandla awo. Igama livela ku-ws2811 driver IC, okuyilapho iqale khona.
Abantu bavame ukwazi lawa ma-LED ngesifinyezo sabo, ws2811. Le RGB LED ws2811 ekwazi ukubhekana nayo inikwa amandla yi-DC 12V, ngakho-ke umehluko we-voltage uyabonakala. Ngisho noma i-DC 12V isetshenziselwa ukunika amandla i-WS2811 RGB LED Controller esiyakhayo namuhla, isengakwazi ukwenza umsebenzi wayo.
Ukuze uthole imininingwane eyengeziwe, ungalanda ifayela le- Imifanekiso ye-WS2811.
Iyini i-WS2812B?
Ngaphakathi I-WS2812B Umthombo wokukhanya we-LED wokulawula okuhlakaniphile yiphakheji lezingxenye ezingu-5050, okuhlanganisa isifunda sokulawula kanye ne-RGB chip. Inesiginali ye-amplifier drive circuit, kanye ne-latch yedatha yembobo esebenza ngobuhlakani. Okunye okwakhelwe kudivayisi kukhona i-oscillator yangaphakathi enembayo kanye nento yokulawula yamanje ehlelekayo. Lezi zingxenye zisebenza ndawonye ukuze zigcine ubude bombala wephoyinti lephikseli bufana.
Kuphrothokholi yokudlulisa idatha, kunesiteshi esisodwa kuphela sokuxhumana se-NZR. Ngemva kokuba i-pixel ivuliwe futhi isethwe kabusha, isilawuli sizothumela idatha embobeni ye-DIN. I-pixel yokuqala izothola idatha yokuqala ye-24-bit futhi iyithumele ku-latch yedatha yangaphakathi. Isignali yangaphakathi yesekhethi yokukhulisa ibumba enye idatha, ebese ithunyelwa ngembobo ye-DO kuphikseli ye-cascade elandelayo.
Ngemva kokuba isignali isithunyelwe, iyasikwa ibe ngamabhithi angu-24 ngephikseli ngayinye. Amaphikseli asebenzisa ubuchwepheshe bokudlulisa obushintsha ngokuzenzakalelayo, okusho ukuthi inani lamaphikseli ku-cascade alinqunyelwe ukuthi isignali ingathunyelwa ngokushesha kangakanani. Ama-LED asebenza nge-voltage ephansi, elungele imvelo futhi yonga amandla amaningi. Futhi zinezinga eliphezulu lokukhanya, i-engeli ebanzi yokuhlakazeka, ukufana okuhle, ukusetshenziswa kwamandla okuphansi, nokuphila isikhathi eside. I-chip edidiyelwe yokulawula kuma-LED iyashintsha ukuze ibe yisekethe enezingxenye ezimbalwa, isikhala esincane, kanye nendlela elula yokuyihlanganisa.
Ukuze uthole imininingwane eyengeziwe, ungalanda ifayela le- Imifanekiso ye-WS2812B.
Uyini Umehluko Phakathi Kwe-WS2811 Ne-WS2812B?
Ukuze i-chip ye-WS2811 LED isebenze kahle, idinga i-voltage engu-12 volts. Ngokuphambene, i-chip ye-WS2812B idinga kuphela i-5V ukuze isebenze. Uma usebenzisa umugqa we-LED onama-LED amaningi, i-voltage izokwehla kakhulu ngobude bomugqa. Lokhu kusho ukuthi ama-LED ambalwa wokugcina ekugcineni komugqa futhi akude kakhulu nebhodi azoba ne-voltage ephansi.
Isibonelo, umugqa wakho unama-LED angu-30, futhi i-voltage yehla ngo-2V eduze nokuphela. I-chip ye-WS2811 izolawula amanye ama-LED, futhi ngalinye lizothola cishe i-10V. Okwe-12V LED, lokhu kusalungile ngoba kwenziwa ukuthi isebenze ngaleyo voltage. Uma usebenzisa i-WS2812B esebenza ku-5V, ukwehla kwamandla kagesi okutholayo kuzoba ngu-3V, hhayi i-5V ebikwayo. Khona lapho, i-voltage yehle kakhulu lapho.
