Mizere ya LED yokhazikika kwezani benchmark pamlingo wina watsopano. Amakupatsirani zosankha zambiri komanso zowunikira zabwino kwambiri monga kuthamangitsa kuthamanga, kuzimiririka koyenda, mayendedwe a meteor, ndi zina zambiri. Mutha kupanganso zowunikira zanu ndi dongosolo lowongolera.
Koma pali mitundu yambiri ya mizere ya LED yokhoza kuyankha kotero kuti ndizovuta kuti anthu azisiyanitsa molondola. Mwachitsanzo, zomwe anthu amafunsa kwambiri ndi pali kusiyana kotani pakati pa WS2811 ndi WS2812B.
Kodi WS2811 ndi chiyani?
WS2811 ndi njira yosavuta yolumikizirana ndiRGB LED. Zikutanthauza kuti mutha kuwonetsa mtundu uliwonse wa LED mothandizidwa ndi chidziwitso chazidziwitso. Mutha kupeza zizindikilozi m'malo angapo, monga pini ya digito pa bolodi la Arduino kapena chowongolera cha LED cha SPI RGB.
Ndikofunika kudziwa kuti chizindikiro ichi ndi kugunda kwa mtima kwa pulse-width-modulated (PWM). Chofunika kwambiri kukumbukira ndi ichi. Pulse width modulation, kapena PWM, ndi yomwe imapatsa ma LED mphamvu zawo. Mawuwa amachokera ku driver ws2811 IC, komwe adayambira.
Anthu nthawi zambiri amadziwa ma LED awa ndi mawu awo, ws2811. RGB LED w2811 yolumikizidwa iyi imayendetsedwa ndi DC 12V, kotero kusiyana kwamagetsi kumatha kuwoneka. Ngakhale DC 12V itagwiritsidwa ntchito kupatsa mphamvu WS2811 RGB LED Controller yomwe tikumanga lero, imatha kugwirabe ntchito yake.
Kuti mudziwe zambiri, mukhoza kukopera Zithunzi za WS2811.
Kodi WS2812B ndi chiyani?
Mkati mwa Chithunzi cha WS2812B Kuwongolera kwanzeru gwero la kuwala kwa LED ndi phukusi la magawo 5050, kuphatikiza gawo lowongolera ndi chipangizo cha RGB. Ili ndi mawonekedwe osinthira ma amplifier drive circuit, komanso mwanzeru-processing digital port data latch. Zomwe zimapangidwanso mu chipangizocho ndi oscillator yolondola yamkati ndi chinthu chowongolera nthawi zonse. Zigawozi zimagwirira ntchito limodzi kuti mtundu wa kuwala kwa pixel ukhale wofanana.
Mu protocol yotumiza deta, pali njira imodzi yokha yolumikizirana ya NZR. Pixel ikatsegulidwa ndi kukonzanso, wowongolera adzatumiza deta ku doko la DIN. Pixel yoyamba ipeza data yoyamba ya 24-bit ndikuitumiza ku latch ya data yamkati. Chizindikiro chamkati cha dera lokulitsa limapanga deta ina, yomwe imatumizidwa kudzera pa doko la DO kupita ku pixel yotsatira.
Chizindikirocho chikatumizidwa, chimadulidwa mpaka 24 bits pa pixel iliyonse. Ma pixel amagwiritsa ntchito ukadaulo wosintha mawonekedwe odzipangira okha, zomwe zikutanthauza kuti kuchuluka kwa ma pixel mu cascade sikumangokhala ndi liwiro lotumiza chizindikiro. Ma LED amayenda pamagetsi otsika, omwe ndi abwino kwa chilengedwe komanso amapulumutsa mphamvu zambiri. Amakhalanso ndi mulingo wowala kwambiri, kufalikira kwakukulu, kufanana kwabwino, kugwiritsa ntchito mphamvu zochepa, komanso moyo wautali. Chip chophatikizika chowongolera mu ma LED chikusintha kukhala dera lokhala ndi magawo ochepa, malo ochepa, komanso njira yosavuta yolumikizirana.
Kuti mudziwe zambiri, mukhoza kukopera Zithunzi za WS2812B.
Kodi Pali Kusiyana Kotani Pakati pa WS2811 Ndi WS2812B?
Kuti chipangizo cha WS2811 LED chigwire ntchito bwino, chimafunika mphamvu yamagetsi 12 volts. Mosiyana ndi izi, chipangizo cha WS2812B chimangofunika 5V kuti chigwire ntchito. Mukamagwiritsa ntchito chingwe cha LED chokhala ndi ma LED ambiri, magetsi amatsika kwambiri kutalika kwa mzerewo. Izi zikutanthauza kuti ma LED ochepa omalizira kumapeto kwa mzerewo komanso kutali kwambiri ndi bolodi adzakhala ndi magetsi otsika.
Mwachitsanzo, mzere wanu uli ndi ma LED 30, ndipo magetsi amatsika ndi 2V pafupi ndi mapeto. Chip cha WS2811 chidzawongolera ma LED ena onse, ndipo aliyense adzapeza pafupifupi 10V. Kwa 12V LED, izi ndizabwino chifukwa zidapangidwa kuti zizigwira ntchito ndi magetsi. Ngati mugwiritsa ntchito WS2812B yomwe imagwira ntchito pa 5V, kutsika kwamagetsi komwe mukukumana nako kudzakhala 3V, osati 5V yomwe ikunenedwa. Pomwepo, magetsi atsika kwambiri pamenepo.

Kusiyana Kwa Kugwiritsa Ntchito Mphamvu Pakati pa WS2812B Ndi WS2811
Chifukwa imayenda pa 12V, WS2811 imagwiritsa ntchito magetsi ochulukirapo. WS8212B, kumbali ina, imagwiritsa ntchito mphamvu zochepa chifukwa imagwira ntchito pa 5V.
Ubwino Ndi Kuipa Kwa WS2811 Ndi WS2812B
Ubwino wa WS2811
- Ma volts khumi ndi awiri amapatsa mphamvu yomwe ikufunika kuti igwire ntchito. Chifukwa chake, imatha kuwongolera ma LED ambiri pamzere.
- Izi zimapangitsa kukhala kosavuta kugwira ntchito ndi ma LED ambiri mwachindunji.
Zoyipa za WS2811
Imatha kuwongolera ma LED opitilira atatu nthawi iliyonse. Pachifukwa ichi, mulingo wowongolera wa granularity wokhala ndi kuchuluka kochepa kwa granularity ndi ma LED atatu. Chifukwa imayenda pa 12V, imagwiritsa ntchito mphamvu zambiri.
Ubwino wa WS2812B
- LED iliyonse imakhala ndi choyatsa / chozimitsa chomwe chimatha kuyatsa kapena kuzimitsa.
- Mu dongosolo la LED, gawo lililonse la ulamuliro limayimiridwa ndi LED imodzi.
- Kuchuluka kwa mphamvu zomwe zimagwiritsidwa ntchito kumatsika.
- Kuti WS2811/WS2812B igwire ntchito, imafunika deta kuti igwirizane ndi nthawi inayake. WS2812B ndiyotsika mtengo komanso yosavuta kupanga, ndipo RGB iliyonse ya RGB imatenga malo ochepa pamizere.
Zotsatira za WS2812B
- Popeza imayenda pa 5V, magetsi amatsika kwambiri pomwe kuchuluka kwa ma LED akuchulukirachulukira.
