Qhov chaw nyob LED strips tsa lub benchmark rau ib theem tshiab. Lawv muab ntau txoj kev xaiv rau koj thiab cov teeb pom kev zoo tshaj plaws xws li khiav chases, ntws ploj, meteor txoj kev, thiab ntau ntxiv. Koj tseem tuaj yeem tsim koj lub teeb pom kev zoo nrog cov kev tswj hwm.
Tab sis muaj ntau ntau hom LED strips uas yog qhov nyuaj rau tib neeg kom paub qhov txawv lawv kom raug. Piv txwv li, qhov neeg nug feem ntau yog Dab tsi yog qhov txawv ntawm WS2811 thiab WS2812B.
WS2811 yog dab tsi?
WS2811 yog ib qho yooj yim addressableRGB LED sawb. Nws txhais tau tias koj tuaj yeem qhia txhua xim LED nrog kev pab ntawm cov ntaub ntawv teeb liab. Koj tuaj yeem tau txais cov teeb liab no los ntawm ntau qhov chaw, xws li tus pin digital ntawm lub rooj tsav xwm Arduino lossis tus tsim SPI RGB LED maub los.
Nws yog ib qho tseem ceeb kom paub tias cov ntaub ntawv qhia no yog pulse-width-modulated (PWM) lub plawv dhia. Qhov tseem ceeb tshaj plaws uas yuav tsum nco ntsoov yog qhov no. Pulse width modulation, los yog PWM, yog dab tsi muab LEDs lawv lub zog. Lo lus los ntawm ws2811 tsav tsheb IC, uas yog qhov uas nws tau pib.
Cov neeg feem ntau paub cov LEDs no los ntawm lawv cov lus, ws2811. Qhov chaw nyob RGB LED ws2811 yog siv los ntawm DC 12V, yog li qhov sib txawv voltage tuaj yeem pom. Txawm hais tias DC 12V siv los ua lub zog rau WS2811 RGB LED Controller peb tab tom tsim hnub no, nws tseem tuaj yeem ua nws txoj haujlwm.
Yog xav paub ntxiv, koj tuaj yeem download tau lub WS2811 specification.
WS2812B yog dab tsi?
Sab hauv WS 2812B ntse tswj LED teeb qhov chaw yog ib pob ntawm 5050 qhov chaw, nrog rau cov tswj Circuit Court thiab RGB nti. Nws muaj lub teeb liab-reshaping amplifier tsav Circuit Court, thiab kev txawj ntse-ua cov ntaub ntawv chaw nres nkoj cov ntaub ntawv latch. Tsis tas li ntawd tsim rau hauv lub cuab yeej yog ib tug precision internal oscillator thiab ib tug programmable tas li tam sim no tswj lub caij. Cov khoom no ua hauj lwm ua ke kom lub pixel point lub teeb xim qhov siab tib yam.
Hauv cov txheej txheem hloov ntaub ntawv, tsuas muaj ib qho kev sib txuas lus NZR nkaus xwb. Tom qab lub pixel tau qhib thiab rov pib dua, tus maub los yuav xa cov ntaub ntawv mus rau DIN chaw nres nkoj. Thawj pixel yuav tau txais thawj 24-ntsis cov ntaub ntawv thiab xa mus rau hauv cov ntaub ntawv latch. Lub teeb liab sab hauv ntawm lub amplification Circuit Court ua rau lwm cov ntaub ntawv, uas yog xa mus los ntawm DO chaw nres nkoj mus rau lub tom ntej cascade pixel.
Tom qab cov teeb liab tau raug xa mus, nws raug txiav mus rau 24 khoom rau txhua pixel. Pixels siv auto-reshaping transmit technology, uas txhais tau hais tias tus naj npawb ntawm pixels nyob rau hauv ib tug cascade tsis txwv los ntawm ceev npaum li cas lub teeb liab yuav xa. LEDs khiav ntawm qhov tsis tshua muaj hluav taws xob, uas yog qhov zoo rau ib puag ncig thiab txuag hluav taws xob ntau. Lawv kuj muaj qhov ci ntsa iab siab, lub kaum sab xis ntawm kev tawg, zoo ib yam, siv hluav taws xob tsawg, thiab lub neej ntev. Cov nti tswj kev sib xyaw ua ke hauv LEDs hloov mus ua ib lub voj voog uas muaj tsawg dua, qhov chaw tsawg dua, thiab ib txoj hauv kev yooj yim dua los muab tso ua ke.
Yog xav paub ntxiv, koj tuaj yeem download tau lub WS2812B specification.
Qhov txawv ntawm WS2811 thiab WS2812B yog dab tsi?
Rau WS2811 LED nti ua haujlwm zoo, nws xav tau qhov hluav taws xob ntawm 12 volts. Hauv qhov sib piv, WS2812B nti tsuas yog xav tau 5V los ua haujlwm. Thaum koj siv LED sawb nrog ntau LEDs, qhov voltage yuav poob ntau raws qhov ntev ntawm lub sawb. Qhov no txhais tau hais tias ob peb LEDs kawg ntawm qhov kawg ntawm lub sawb thiab deb tshaj plaws ntawm lub rooj tsavxwm yuav muaj qhov qis dua.
Piv txwv li, koj lub strip muaj 30 LEDs, thiab qhov hluav taws xob poob los ntawm 2V ze rau qhov kawg. Lub WS2811 nti yuav tswj qhov seem ntawm LEDs, thiab txhua tus yuav tau txais txog 10V. Rau 12V LED, qhov no tseem zoo vim tias nws tau ua haujlwm nrog qhov voltage. Yog tias koj siv WS2812B uas ua haujlwm ntawm 5V, qhov hluav taws xob poob koj qhov kev paub yuav yog 3V, tsis yog 5V uas tau tshaj tawm. Nyob rau ntawd, qhov voltage tau poob qis heev.
