Imigca ye-LED enokudityaniswa nyusa umgangatho ukuya kwinqanaba elitsha ngokupheleleyo. Bakunika iinketho ezingakumbi kunye neziphumo zokukhanya ezigqwesileyo ezinje ngokubaleka, ukucima okuhambayo, iindlela zemeteor, nokunye okuninzi. Ungade uyila iziphumo zakho zokukhanyisa kunye nenkqubo yokulawula.
Kodwa kukho iintlobo ezininzi zeentambo ze-LED ezinokulungiseka kangangokuba kunzima ukuba abantu bahlule ngokuchanekileyo. Ngokomzekelo, eyona nto abantu bayibuzayo kukuba yintoni umahluko phakathi kwe-WS2811 kunye ne-WS2812B.
Yintoni i-WS2811?
I-WS2811 sisixhobo esilula esinokuhanjiswa kwiRGB LED. Kuthetha ukuba unokubonisa umbala ngamnye we-LED ngoncedo lwesignali yolwazi. Unokufumana le miqondiso kwiindawo ezininzi, njengepini yedijithali kwibhodi ye-Arduino okanye isilawuli esifanelekileyo se-SPI RGB LED.
Kubalulekile ukwazi ukuba olu phawu lolwazi sisingqi sentliziyo se-pulse-width-modulated (PWM). Eyona nto ibalulekileyo ekufuneka uyikhumbule yile. Ukumodareyitha kobubanzi be-Pulse, okanye i-PWM, yinto enika ii-LED amandla azo. Igama livela kumqhubi we-ws2811 IC, kulapho iqale khona.
Abantu bahlala bezazi ezi LEDs ngesifinyezo sabo, ws2811. Le RGB ye-LED ye-ws2811 idilesi inikwe amandla yi-DC 12V, ngoko ke umahluko wombane unokubonwa. Nokuba i-DC 12V isetyenziselwa ukunika amandla iWS2811 RGB LED Controller esiyakhayo namhlanje, isenokwenza umsebenzi wayo.
Ukuze ufumane iinkcukacha ezithe vetshe, unokukhuphela i Iimpawu zeWS2811.
Yintoni i-WS2812B?
Ngaphakathi WS2812B ulawulo olukrelekrele Umthombo ukukhanya LED yipakethe 5050 iinxalenye, kuquka isiphaluka ulawulo kunye RGB chip. Ine-signal-reshaping amplifier drive circuit, kunye ne-intelligent-processing digital port data latch. Kwakhona kwakhiwe kwisixhobo kukuchaneka kwe-oscillator yangaphakathi kunye neprogrammable eqhubekayo yolawulo lwangoku. La malungu asebenza kunye ukugcina umbala we-pixel point ubude bufana.
Kwiprotocol yokudlulisa idatha, kukho ishaneli yonxibelelwano yeNZR kuphela. Emva kokuba i-pixel ivuliwe kwaye isetyenzisiwe, umlawuli uya kuthumela idatha kwi-DIN port. I-pixel yokuqala iya kufumana idatha yokuqala ye-24-bit kwaye iyithumele kwi-latch yedatha yangaphakathi. Umqondiso wangaphakathi wesekethe yokukhulisa imilo enye idatha, ethi ke ithunyelwe nge-DO port ukuya kwi-pixel elandelayo ye-cascade.
Emva kokuba umqondiso uthunyelwe, unqunyulwa ukuya kutsho kumasuntswana angama-24 kwipixel nganye. Ii-pixels zisebenzisa itekhnoloji yokuhambisa i-auto-reshaping, okuthetha ukuba inani leepixels kwi-cascade alikhawulelwanga ukuba isignali inokuthunyelwa ngokukhawuleza kangakanani. Ii-LED zisebenza kumbane ophantsi, okulungileyo kokusingqongileyo kwaye zigcina amandla amaninzi. Bakwanayo nenqanaba eliphezulu lokukhanya, i-angle ebanzi yokusasazeka, ukufana okuhle, ukusetyenziswa kwamandla aphantsi, kunye nobomi obude. I-chip yokulawula edibeneyo kwii-LED iyatshintsha ibe yisekethe eneendawo ezimbalwa, indawo encinci, kunye nendlela elula yokuyihlanganisa.
Ukuze ufumane iinkcukacha ezithe vetshe, unokukhuphela i Iimpawu zeWS2812B.
Yintoni Umahluko phakathi kweWS2811 kunye neWS2812B?
Ukuze i-chip ye-WS2811 ye-LED isebenze ngokufanelekileyo, idinga amandla ombane angama-12 volts. Ngokwahlukileyo, i-chip ye-WS2812B idinga kuphela i-5V ukuze isebenze. Xa usebenzisa i-strip ye-LED ene-LED ezininzi, i-voltage iya kuhla kakhulu kubude bomgca. Oku kuthetha ukuba ii-LED ezimbalwa zokugqibela ekupheleni komtya kunye nokude kakhulu kwibhodi ziya kuba nombane ophantsi.
Umzekelo, umtya wakho unee-LED ezingama-30, kwaye amandla ombane ahla nge-2V kufutshane nesiphelo. I-chip ye-WS2811 iya kulawula ezinye ii-LED, kwaye nganye iya kufumana malunga ne-10V. Kwi-LED ye-12V, oku kusalungile kuba yenziwe ukuba isebenze ngaloo mbane. Ukuba usebenzisa i-WS2812B esebenza kwi-5V, ukuhla kwamandla ombane oza kuba nakho kuya kuba yi-3V, kungekhona i-5V exeliweyo. Kanye apho, i-voltage yehle kakhulu apho.
