I-WS2812B yenye yezona zisetyenziswa kakhulu imichilo ye-LED ephathwayo kunye nokuya kwisiseko soyilo oludanyazayo ngenxa yombane ophantsi wokusebenza, ukukhanya okuphezulu, kunye nobunzulu bombala obuhle. I WS2812B yindlela ekrelekrele yokulawula izibane ze-LED, enkosi kuphuculo lwayo ukusuka kwi-WS2812 yoqobo. Olu hlaziyo ludibanisa i-chip ye-RGB kunye nolawulo lokujikeleza kwi-RGB 5050 LED. Le LED yedijithali. Ke, abaqhubi babo abazinikeleyo balawula ukuqaqamba kunye nombala we-LED nganye ejongiweyo. Oku kuthetha ukuba i-LED nganye inamandla okuba nombala owahlukileyo kwi-LED ecaleni kwayo. Oku kuvula ucango lweziphumo zokukhanya ezicacileyo kunye nobuhle.
I-WS2813 i-strip ye-LED enedilesi yeyona nguqulelo yamva nje yolu hlobo loluhlu lwe-LED, olusetyenziswa kakhulu. Le nguqulo entsha ye-WS2812B ingcono kunendala. I-RGB 5050 LED esuka kwi-WS2813 inesiphaluka solawulo kunye ne-chip ye-RGB, njenge-WS2812B. Oku kuthetha ukuba i-LED nganye inokulawulwa ngendlela yayo. Yintoni eyenza i-WS2813 yahluke kumanduleli wayo ophumelele kakhulu, i-WS2812B, kwaye yintoni eyenza ifane? Kuba iyinguqulelo ehlaziyiweyo, silindele ukuba ibengcono kune-WS2812B kwezinye izintlu. Makhe sijonge ukuba ezi zimbini zahluke njani kwaye zifana njani.
Ngowuphi uMahluko oPhakathi kwe-WS2813 kunye ne-WS2812B?
Isici sokudlula i-LED yeyona nto ihlulayo phakathi kwezi zintlu zimbini zikhokelwayo. I-WS2813 iphuculwe kakhulu ngaphezu kwe-WS2812B eyandulelayo, kuba inokudibanisa kwiimpawu ezimbini ngaxeshanye. Kwakhona, iintambo zineendawo apho umqondiso uqhawuka khona ukuze ukuhanjiswa kungayeki. Ke, nokuba i-LED enye embindini womtya iya kutsha, ayizukuphazamisa isekethe. Logama nje kungekho nanye yee-LED ezikufutshane ezaphukileyo, isiginali iya kuhlala isiya kwezinye ii-LED, kwaye ziya kukhanya njengesiqhelo. Kwimeko ye-WS2812B, yonke isekethe iya kusilela ukuba i-LED enye yophukile okanye itshisiwe. Nje ukuba udlule kwi-LED eyaphukileyo okanye etshileyo, ezinye ii-LED ezikumtya aziyi kukhanya.
I-WS2812B inomqondiso omnye wedatha, yiyo loo nto kukho umahluko. Ngenxa yoko, i-diode eyonakalisiweyo ekhupha ukukhanya, njengaleyo etshisiweyo okanye eqhekekileyo, inokumisa i-diode elandelayo kwi-strip ekusebenzeni ngokuchanekileyo. Ngakolunye uhlangothi, i-WS2813 isebenzisa iimpawu ezimbini zedatha. Oku kuthetha ukuba i-pixel kwikhonkco le-LEDs ayiphumelelanga, ayiyi kumisa ukuhamba kwedatha. Kwelinye icala, ukuba ii-LED ezimbini ezisondeleleneyo zaphukile okanye zitshisiwe, ukuhanjiswa komqondiso kuya kuthotywa. Nokuba i-LED enye kwikhonkco yaphukile, ayisayi kuba yinto enkulu. Ungaqhubeka usebenza nezinye ii-LED ngelixa ucinga malunga nendlela yokulungisa ingxaki.
Xa kuthelekiswa phakathi kwezi zimbini, kucacile ukuba i-WS2813 yeyona nto ithembekileyo ye-LED strip.
Ukufumana iinkcukacha ezithe vetshe unokukhuphela ezi nkcukacha zingezantsi:

Iimpawu zeWS2813
Ingaba iFrequency ye-WS2813 yahluke njani kweye-WS2812B?
Iintambo ze-LED ze-WS2813 zinezinga eliphezulu lokuphindaphinda kunangaphambili, i-WS2812B, ebanika inzuzo eyongezelelweyo. Xa kuthelekiswa neyandulelayo, i-WS2812B, ene-frequency ye-400 hertz kuphela, le modeli ine-frequency ephezulu kakhulu. Ukuhlaziya kwayo ngama-2,000 hertz, okungaphezulu kakhulu kwama-400 hertz.
Ke, i-WS2813 inesiphumo esihle sokubonisa esiphantse singaqhwayizi.
Linjani ixesha lokuSeta ngokutsha leWS2812B xa lithelekiswa neWS2813?
I-WS2813 inexesha lokuphinda lisetyenziselwe ii-microseconds ezingama-250, nto leyo eyivumela ukuba isebenze bhetele kumaza asezantsi kunye nee-microcontrollers ezingabizi kakhulu.
Ngaba sinokusebenzisa uMlawuli ofanayo kuzo zombini i-WS2813 kunye ne-WS2812B?
Into enhle kukuba zombini i-WS2812B kunye ne-WS2813 inokusebenzisa okufanayo umlawuli.
Mhlawumbi awazi kakhulu malunga nemicu ye-LED, akunjalo? Ukuba oku kunjalo, usenokungazi ukuba ukuziplaga nje kwisixhobo sombane akuyi kubenza bakhanyise. Kwakhona, kunzima ukutshintsha imibala ngee-LED eziqhelekileyo eziqhelekileyo, kwaye izibane azihlali ngalo lonke ixesha. Kufuneka idityaniswe kumlawuli ukuze umyalelo osebenzayo uthunyelwe kwii-LEDs ngayo. Abalawuli baquka iArduino, esetyenziswa ngabantu abaninzi, kunye neRaspberry Pi. Ukusebenzisa useto olucwangcisiweyo kwisilawuli, umlawuli "uxelela" i-LED nganye ukuba imele ibe yintoni umbala, ifanele ikhanye kangakanani, kwaye kufuneka ihlale ixesha elingakanani kweso simo.
Isekethe edibeneyo (IC) efunyenwe kwii-LED ze-WS2812B yenza ukuba ii-LED zikwazi ukunxibelelana ngekhebula elilodwa. Oku kukuvumela ukuba ulawule inani elikhulu le-LED ukusuka kwiphini enye kumlawuli wakho. Kukho izikhonkwane ezintathu kwiintambo ze-LED zamandla (+5V), umhlaba (GND), kunye nedatha (iDin kunye neDout). Ukudibanisa amandla kunye nezikhonkwane zomhlaba kumcu wakho qinisekisa ukuba ufumana amandla, ngelixa i-pin yedatha yenza ukuba inxibelelane nomlawuli.
Ukuba ufuna ukusebenzisa i-Arduino ukulawula umgca ofuna i-5V yamandla, akufanele ube nayo nayiphi na ingxaki yokwenza oko nge-5V ephumayo ebhodini. Ngakolunye uhlangothi, ukuba ufuna ukuqhuba i-strip yakho ye-LED kunye ne-Raspberry Pi okanye i-ESP8266, ethumela iimpawu kwi-3.3V, uya kufuna imodyuli ye-logic-level converter ukuze utshintshe isignali yedatha ukusuka kwi-3.3V ukuya kwi-5V. Iimpawu zithunyelwa kwezi zixhobo kwi-3.3V. Ngaphandle kokuba uyenzile oku, umtya we-LED owusebenzisayo usenokungasebenzi.
Ngaba Zombini i-WS2813 kunye ne-WS2812B ziSebenzisa amathala eencwadi afanayo?
Zombini i-WS2813 kunye ne-WS2812B zisebenzisa amathala eencwadi afanayo. Le micu mibini ifuna amathala eencwadi ukuba akhutshelwe phambi kokuba alawulwe ukuvelisa iziphumo zokukhanya ze-LED eziphambeneyo. La mathala eencwadi alawula i-LED nganye, evumela ukuveliswa kweepateni ezicacileyo. Nangona kunjalo, umlawuli ochaphazelekayo uchaphazela ukufumaneka kwamathala eencwadi athile. Uninzi lwala mathala eencwadi afumaneka simahla kwi-intanethi.
Ngezixhobo zakho ze-ESP8266 kunye ne-Arduino, ungasebenzisa la mathala eencwadi alandelayo:

Ngaba iSibonelelo saMandla kwi-WS2812B Strip siyakwahluka kwi-WS2813 Strip?
Ekukhanyeni okupheleleyo, zombini ii-LED zifuna malunga ne-60mA yangoku, ngoko ke iinkqubo ze-WS2812B zinokusebenzisa iintlobo ezifanayo zemithombo yamandla. Umthamo wamandla afunekayo uya kuhlala uhluka ukusuka kwiseti enye yeentambo ze-LED ukuya kwelinye. Ukugcina umtya wakho ekuqaqambe okufanelekileyo, kuya kufuneka usebenzise umthombo wamandla onokuphatha umzobo wangoku. Ukunika amandla umtya omnye wee-LED ezingama-60 ekuqaqambe okukhulu, uya kudinga umthombo wamandla olinganiselwe ubuncinci be-3.6A (60 LEDs x 60mA). Ukusebenzisa i-USB 2.0 port enikezela nge-0.9A, unokuqhuba ngokukhuselekileyo imicu ye-0.9A / 0.06A = ii-LED ezili-15.
Amaxabiso eWS2813 kunye neWS2812B LEDs athelekiseka njani?
Inyani yokuba i-WS2813 ibiza kakhulu kuneyandulelayo akufuneki imangalise. Ngokusekelwe kwinto esiyifumene kuphando lwethu, ixabiso le-WS2813 ye-LED strip malunga ne-20% ngaphezu kweyangaphambili, i-WS2812B. Umahluko wexabiso phakathi kwezi zimbini ze-LED azikho mkhulu kakhulu. Nangona i-WS2813 sele ikwintengiso ixesha elide, iya isanda ngokuthandwa. Ekuhambeni kwexesha, kunokuba ngcono kunemodeli efike ngaphambi kwayo.
