WS2812B yog ib qho ntawm feem ntau siv chaw nyob LED strips thiab mus-rau lub hauv paus ntawm flashing designs vim nws tsis tshua muaj kev khiav hauj lwm voltage, siab brightness, thiab zoo xim tob. Cov WS 2812B yog txoj kev ntse dua los tswj LED teeb pom kev zoo, ua tsaug rau nws qhov kev hloov kho tshiab los ntawm tus thawj WS2812. Qhov kev hloov kho no suav nrog RGB nti thiab tswj kev sib txuas rau hauv RGB 5050 LED. Cov LED no yog digital. Yog li, lawv cov neeg tsav tsheb tshwj xeeb tswj qhov ci thiab xim ntawm txhua tus neeg hais txog LED. Qhov no txhais tau hais tias txhua lub LED muaj peev xwm ua tau txawv xim ntawm LED nyob ib sab ntawm nws. Qhov no qhib lub qhov rooj kom nthuav dav thiab ua kom zoo nkauj zoo nkauj teeb pom kev zoo.

Lub WS2813 addressable LED sawb yog qhov tshiab tshaj plaws ntawm no hom LED sawb, uas yog siv ntau heev. Qhov tshiab ntawm WS2812B no zoo dua li qub. RGB 5050 LED los ntawm WS2813 muaj kev tswj xyuas Circuit Court thiab RGB nti, ib yam li WS2812B. Qhov no txhais tau tias txhua LED tuaj yeem tswj tau hauv nws txoj kev. Dab tsi ua rau WS2813 txawv ntawm nws cov thawj coj ua tau zoo, WS2812B, thiab dab tsi ua rau nws zoo ib yam? Txij li nws yog qhov hloov kho tshiab, peb cia siab tias nws yuav zoo dua li WS2812B hauv qee qhov ntau. Cia peb saib seb ob qhov sib txawv li cas thiab lawv zoo li cas.

Qhov txawv ntawm WS2813 thiab WS2812B yog dab tsi?

LED bypassing feature yog qhov sib txawv ntawm ob lub teeb coj no. WS2813 tau txhim kho zoo dua nws cov thawj coj WS2812B, vim tias nws tuaj yeem txuas rau ob lub teeb liab ib txhij. Tsis tas li ntawd, cov cables muaj qhov chaw uas lub teeb liab tawg kom qhov kev sib kis tsis nres. Yog li, txawm tias ib qho LED nyob rau hauv nruab nrab ntawm lub sawb kub hnyiab tawm, nws yuav tsis cuam tshuam lub voj voog. Tsuav tsis muaj lwm yam LEDs nyob ze tau tawg, lub teeb liab yuav txuas mus rau lwm cov LEDs, thiab lawv yuav ci li qub. Nyob rau hauv rooj plaub ntawm WS2812B, tag nrho Circuit Court yuav ua tsis tau yog tias txawm tias ib qho LED tawg lossis hlawv tawm. Thaum koj dhau los ntawm qhov tawg lossis hlawv tawm, lwm LEDs ntawm lub sawb yuav tsis teeb.

Lub WS2812B tsuas muaj ib lub teeb liab cov ntaub ntawv, uas yog vim li cas thiaj li muaj qhov sib txawv. Vim li no, lub teeb hluav taws xob puas ntsoog, xws li ib qho uas tau hlawv tawm lossis tawg, tuaj yeem nres lub diode tom ntej hauv kab txaij los ntawm kev ua haujlwm kom raug. Ntawm qhov tod tes, WS2813 siv ob cov ntaub ntawv qhia. Qhov no txhais tau hais tias yog tias lub pixel hauv cov saw hlau ntawm LEDs tsis ua haujlwm, nws yuav tsis nres cov ntaub ntawv ntws. Ntawm qhov tod tes, yog tias ob lub LEDs ze rau ib leeg yog tawg lossis hlawv tawm, lub teeb liab hloov mus yuav qeeb. Txawm hais tias ib qho LED hauv cov saw hlau tawg, nws yuav tsis yog qhov loj. Koj tuaj yeem ua haujlwm nrog lwm cov LEDs thaum koj xav txog yuav kho qhov teeb meem li cas.

Thaum muab piv ntawm ob, nws yog qhov tseeb tias WS2813 yog qhov zoo tshaj plaws LED sawb.

Qhov zaus ntawm WS2813 txawv li cas ntawm WS2812B?

Lub WS2813 LED strips muaj qhov zaus ntau dua li lawv cov thawj coj, WS2812B, uas ua rau lawv muaj txiaj ntsig ntxiv. Piv rau nws cov thawj, WS2812B, uas tsuas muaj zaus ntawm 400 hertz, tus qauv no muaj ntau zaus. Nws tus nqi refresh yog 2,000 hertz, uas yog ntau tshaj 400 hertz.

Yog li, WS2813 muaj cov nyhuv zoo heev uas yuav luag tsis muaj flickering.

Lub sij hawm rov pib dua ntawm WS2812B piv rau WS2813 li cas?

Lub WS2813 muaj lub sijhawm rov pib dua ntawm 250 microseconds, uas cia nws ua haujlwm zoo dua ntawm cov zaus qis dua thiab nrog cov microcontrollers kim dua.

Peb puas tuaj yeem siv tib tus tswj hwm rau WS2813 thiab WS2812B?

Qhov zoo yog tias ob qho tib si WS2812B thiab WS2813 tuaj yeem siv tib yam xws li.

Tej zaum koj tsis paub ntau txog LED strips, txoj cai? Yog tias qhov no tshwm sim, tej zaum koj yuav tsis paub tias tsuas yog ntsaws rau hauv lub qhov hluav taws xob yuav tsis ua rau lawv teeb. Tsis tas li ntawd, nws nyuaj dua los hloov cov xim nrog cov LEDs tsis tu ncua, thiab lub teeb tsis nyob ntawm txhua lub sijhawm. Nws yuav tsum tau txuas mus rau ib tus maub los kom cov lus txib siv tau tuaj yeem xa mus rau LEDs los ntawm nws. Cov tswj hwm suav nrog Arduino, uas yog siv los ntawm ntau tus neeg, thiab Raspberry Pi. Siv cov chaw koj tau programmed rau hauv lub maub los, tus maub los "qhia" txhua lub LED seb nws yuav tsum yog xim, yuav tsum ci npaum li cas, thiab ntev npaum li cas nws yuav tsum nyob hauv lub xeev ntawd.

Kev sib xyaw ua ke (IC) pom nyob rau hauv WS2812B LEDs ua rau nws ua tau rau cov LEDs sib txuas lus nrog ib lub cable. Qhov no tso cai rau koj los tswj ntau tus LEDs los ntawm ib tus pin ntawm koj tus maub los. Muaj peb tus pins ntawm LED strips rau lub zog (+ 5V), hauv av (GND), thiab cov ntaub ntawv (Din thiab Dout). Txuas lub zog thiab hauv av pins rau koj lub sawb kom nws tau txais lub zog, thaum cov ntaub ntawv tus pin tso cai rau nws sib txuas lus nrog tus maub los.

Yog tias koj xav siv Arduino los tswj lub sawb uas xav tau 5V ntawm lub zog, koj yuav tsum tsis txhob muaj teeb meem ua li ntawd nrog 5V tso tawm ntawm lub rooj tsavxwm. Ntawm qhov tod tes, yog tias koj xav khiav koj lub LED sawb nrog Raspberry Pi lossis ESP8266, uas xa cov teeb liab ntawm 3.3V, koj yuav xav tau lub logic-theem converter module hloov cov ntaub ntawv teeb liab ntawm 3.3V rau 5V. Cov teeb liab raug xa los ntawm cov khoom siv no ntawm 3.3V. Tshwj tsis yog tias koj ua qhov no, LED sawb koj siv yuav tsis ua haujlwm.

Puas yog Ob Lub WS2813 Thiab WS2812B Siv Ib Lub Tsev Qiv?

Ob lub WS2813 thiab WS2812B siv cov tsev qiv ntawv zoo sib xws. Ob lub strips no xav tau cov tsev qiv ntawv rub tawm ua ntej lawv tuaj yeem tswj tau los tsim cov teeb pom kev vwm vwm. Cov tsev qiv ntawv no tswj hwm txhua LED, tso cai rau tsim cov qauv tsim. Txawm li cas los xij, tus tswj hwm hauv nqe lus nug cuam tshuam rau qhov muaj cov tsev qiv ntawv tshwj xeeb. Feem ntau ntawm cov tsev qiv ntawv no tau rub tawm dawb hauv internet.

Puas Yuav Lub Hwj Chim Rau Ib WS2812B Sawb Yuav Sib Txawv Los Ntawm WS2813 Sawb?

Ntawm qhov ci ci tag nrho, ob lub LEDs xav tau nyob ib puag ncig 60mA ntawm tam sim no, yog li WS2812B tshuab tuaj yeem siv tib hom kev siv hluav taws xob. Tus nqi ntawm lub zog xav tau yuav ib txwm txawv ntawm ib pawg ntawm LED strips mus rau lwm qhov. Txhawm rau kom koj lub sawb ntawm qhov ci ntsa iab, koj yuav tsum tau siv lub zog hluav taws xob uas tuaj yeem tswj tau qhov kos tam sim no. Txhawm rau ua kom muaj zog ib leeg ntawm 60 LEDs ntawm lawv qhov siab tshaj plaws, koj yuav xav tau lub zog hluav taws xob tsawg kawg 3.6A (60 LEDs x 60mA). Siv USB 2.0 chaw nres nkoj uas muab 0.9A, koj tuaj yeem ua haujlwm ruaj ntseg ntawm 0.9A / 0.06A = 15 LEDs.

Yuav Ua Li Cas Tus Nqi Ntawm WS2813 Thiab WS2812B LEDs Sib Piv?

Qhov tseeb tias WS2813 kim dua li nws cov thawj coj yuav tsum tsis txhob xav tsis thoob. Raws li qhov peb pom hauv peb qhov kev tshawb fawb, tus nqi ntawm WS2813 LED sawb yog li 20% ntau dua li ntawm nws cov thawj, WS2812B. Tus nqi sib txawv ntawm ob lub LED strips no tsis loj heev. Txawm hais tias WS2813 tau nyob rau hauv kev ua lag luam ib ntus, nws maj mam nce nrov. Nyob rau lub sijhawm ntev, nws yuav zoo dua li cov qauv uas tuaj ua ntej.
