Inowanikwa ma LED mitsetse simudza bhenji kusvika kune imwe nhanho itsva. Ivo vanokupa dzimwe sarudzo uye mamwe akanakisa mwenje mhedzisiro senge kumhanya kudzingirira, inoyerera fade, meteor nzira, uye zvimwe zvakawanda. Iwe unogona kutogadzira yako yekuvhenekesa maitiro neiyo control system.
Asi kune akawanda marudzi eanogadziriswa ma LED mitsetse zvekuti zvinonetsa kuti vanhu vasiyanise nemazvo. Semuenzaniso, chinonyanya kubvunzwa nevanhu ndechekuti ndeupi musiyano uripo pakati peWS2811 neWS2812B.
Chii chinonzi WS2811?
Iyo WS2811 iri nyore addressableRGB LED strip. Zvinoreva kuti iwe unogona kuratidza yega yega ruvara rwe LED nerubatsiro rwechiratidzo cheruzivo. Iwe unogona kuwana aya masaini kubva kunzvimbo dzinoverengeka, sedhijitari pini pane Arduino bhodhi kana yakakodzera SPI RGB LED controller.
Izvo zvakakosha kuti uzive kuti chiratidzo cheruzivo ichi ndeye pulse-width-modulated (PWM) kurova kwemoyo. Chinhu chakakosha kurangarira ndeichi. Pulse width modulation, kana PWM, ndiyo inopa ma LED simba ravo. Izwi rinobva kune ws2811 mutyairi IC, kunova ndiko kwarakabva.
Vanhu vanowanzoziva ma LED aya neacronym yavo, ws2811. Iyi inogadziriswa RGB LED ws2811 inofambiswa neDC 12V, saka mutsauko wemagetsi unogona kuoneka. Kunyangwe kana DC 12V ichishandiswa kusimbisa iyo WS2811 RGB LED Controller yatiri kuvaka nhasi, inogona kuita basa rayo.
Kuti uwane rumwe ruzivo, unogona kudhawunirodha iyo WS2811 tsanangudzo.
Chii chinonzi WS2812B?
Inside the WS2812B intelligent control LED light source pasuru yezvikamu 5050, kusanganisira dunhu rekutonga uye RGB chip. Iyo ine chiratidzo-reshaping amplifier drive circuit, uye nehungwaru-kugadzirisa dhijitari port data latch. Zvakare zvakavakwa mumudziyo ndeye chaiyo yemukati oscillator uye programmable inogara iripo yekudzora chinhu. Izvi zvikamu zvinoshanda pamwechete kuchengetedza pixel point mwenje weruvara kureba zvakafanana.
Mune iyo data yekufambisa protocol, pane imwe chete NZR yekutaurirana chiteshi. Mushure mekunge pixel yavhurwa uye nekugadziriswazve, mutongi anotumira data kuDIN port. Pixel yekutanga inowana yekutanga 24-bit data uye kuitumira kune yemukati data latch. Chiratidzo chemukati chedunhu rekusimudzira chinoumba imwe data, inozotumirwa kuburikidza neDO port kune inotevera cascade pixel.
Mushure mekunge chiratidzo chatumirwa, chinotemwa kusvika ku24 bits kune yega pixel. Pixels anoshandisa auto-reshaping transmit tekinoroji, izvo zvinoreva kuti huwandu hwemapixels mune cascade hahuna kuganhurirwa nekukasira kutumirwa kwechiratidzo. Ma LED anomhanya pamhepo yakaderera, iyo yakanaka kune zvakatipoteredza uye inochengetedza simba rakawanda. Ivo zvakare vane mwero wepamusoro wekupenya, kona yakafara yekuparadzira, yakanaka kufanana, kuderera kwekushandisa simba, uye hupenyu hurefu. Iyo yakabatanidzwa yekudzora chip muma LEDs iri kuchinja kuita dunhu rine zvikamu zvishoma, nzvimbo shoma, uye nzira iri nyore yekuisa pamwe chete.
Kuti uwane rumwe ruzivo, unogona kudhawunirodha iyo WS2812B tsanangudzo.
Ndeupi Musiyano Pakati PeWS2811 Uye Iyo WS2812B?
Kuti WS2811 LED chip ishande nemazvo, inoda voltage yegumi nemaviri volts. Mukupesana, iyo WS12B chip inongoda 2812V kushanda. Paunoshandisa tambo ye LED ine akawanda ma LED, iyo voltage inodonha yakawanda pamwe nehurefu hwetambo. Izvi zvinoreva kuti ma LED mashoma ekupedzisira pamagumo emutsetse uye kure kure nebhodhi achave nemhepo yakaderera.
Semuenzaniso, tambo yako ine 30 LEDs, uye voltage inodonha ne2V pedyo nekumagumo. Iyo WS2811 chip ichadzora mamwe maLED, uye imwe neimwe ichawana inenge 10V. Kune 12V LED, izvi zvichiri zvakanaka nekuti yakagadzirwa kuti ishande neiyo voltage. Kana ukashandisa WS2812B inoshanda pa5V, kudonha kwevoltage kwaunoona kunenge kuri 3V, kwete iyo 5V yakataurwa. Ikoko, voltage yakadzikira zvakanyanya ipapo.
