Iyo WS2812B ndeimwe yeanonyanya kushandiswa inogadziriswa ma LED mitsetse uye kuenda-kune hwaro hwemagadzirirwo anopenya nekuda kwekuderera kwayo kwemagetsi ekushanda, kupenya kwakanyanya, uye kunaka kwemavara kudzika. The WS2812B inzira yakangwara yekudzora mwenje we LED, nekuda kwekusimudzira kwayo kubva kune yekutanga WS2812. Ongororo iyi inobatanidza iyo RGB chip uye kutonga kutenderera muRGB 5050 LED. Iyi LED ndeye digital. Saka, vatyairi vavo vakazvitsaurira vanobata kupenya uye ruvara rweyega yega inotariswa LED. Izvi zvinoreva kuti LED yega yega ine mukana wekuve wakasiyana ruvara kubva kune LED iri padivi payo. Izvi zvinovhura musuwo weakaomesesa uye aesthetically anofadza mwenje mhedzisiro.
Iyo WS2813 inogadziriswa LED strip ndiyo yazvino vhezheni yerudzi urwu rwe LED strip, iyo inoshandiswa zvakanyanya. Iyi vhezheni itsva yeWS2812B iri nani pane yekare. Iyo RGB 5050 LED kubva kuWS2813 ine dunhu rekutonga uye RGB chip, senge WS2812B. Izvi zvinoreva kuti LED yega yega inogona kudzorwa munzira yayo. Chii chinoita kuti WS2813 isiyane neyakatangira yakabudirira kwazvo, iyo WS2812B, uye chii chinoita kuti ive yakafanana? Sezvo iri vhezheni yakagadziridzwa, isu tinotarisira kuti ive nani pane iyo WS2812B mune mamwe masanji. Ngatitarisei kuti zviviri izvi zvakasiyana sei uye zvakafanana sei.
Ndeupi Musiyano Mukuru Pakati peWS2813 Uye WS2812B?
Iyo LED yekupfuura ficha ndiyo inosiyanisa pakati peaya maviri akatungamira mitsetse. Iyo WS2813 yakagadziridzwa zvakanyanya pamusoro peyakatangira WS2812B, nekuti inogona kubatana kune maviri masaini panguva imwe chete. Zvakare, tambo dzine nzvimbo dzinotsemuka chiratidzo kuitira kuti kutapurirana kurege kumira. Saka, kunyangwe imwe LED iri pakati pemutsetse ikapisa, haikanganise dunhu. Chero bedzi pasina mamwe ma LED ari pedyo akatyoka, chiratidzo chinoramba chichienda kune mamwe maLED, uye anopenya semazuva ese. Panyaya yeWS2812B, dunhu rese rinotadza kana kana LED imwe ikatyoka kana kupiswa. Kana iwe uchinge wapfuura yakatyoka kana kupiswa-kunze LED, mamwe maLED ari pamutsetse haazovheneke.
Iyo WS2812B inongova nechiratidzo chimwe chete chedata, ndosaka paine musiyano. Nekuda kweizvi, yakakuvadzwa chiedza-emitting diode, senge yakapiswa kunze kana kuputika, inogona kumisa diode inotevera mumutsara kubva kushanda nemazvo. Kune rimwe divi, iyo WS2813 inoshandisa masaini maviri data. Izvi zvinoreva kuti kana pixel mucheni ye LEDs ikatadza, haizomise kuyerera kwe data. Kune rimwe divi, kana ma LED maviri ari padyo kune mumwe nemumwe akatyoka kana kupiswa kunze, kufambisa kwechiratidzo kunononoka. Kunyange kana imwe LED mucheni yakaputsika, haizove chinhu chikuru. Iwe unogona kuramba uchishanda nemamwe ma LED iwe uchifunga nezve kugadzirisa dambudziko.
Kana ichienzaniswa pakati pezviviri izvi, zviri pachena kuti iyo WS2813 ndiyo yakavimbika LED strip.
Kuti uwane rumwe ruzivo iwe unogona kudhawunirodha pazasi yakatarwa:

Iyo Frequency YeWS2813 Yakasiyana Sei Neiyo YeWS2812B?
Iyo WS2813 LED mitsetse ine yakakwira frequency chiyero kupfuura yakatangira, iyo WS2812B, inovapa imwe bhenefiti. Kuenzaniswa neyakatangira, iyo WS2812B, iyo inongove ine frequency ye400 hertz, iyi modhi ine yakakwira frequency. Mwero wayo wekuzorodza i2,000 hertz, iyo yakawanda kupfuura 400 hertz.
Saka, iyo WS2813 ine yakanakisa ratidziro mhedzisiro isingaite inopenya.
Iyo nguva yekumisikidzazve yeWS2812B inofananidzwa sei neWS2813?
Iyo WS2813 ine nguva yekumisikidza ye250 microseconds, iyo inoita kuti ishande zvirinani pazasi mafrequency uye ine isingadhure mamicrocontrollers.
Tinogona Kushandisa Mutongi Mumwechete Kune Zvose WS2813 Uye WS2812B?
Chinhu chakanaka ndechekuti vese WS2812B neWS2813 vanogona kushandisa zvakafanana Controller.
Iwe pamwe hauzive zvakawanda nezve LED mitsetse, handiti? Kana zviri izvo, ungasaziva kuti kungovaisa mudura remagetsi hakuite kuti vavheneke. Zvakare, zvakanyanya kuoma kushandura mavara neanogara achingoita ma LED, uye mwenje haagare akabatikana nguva dzese. Inoda kusungirirwa kune mutongi kuitira kuti murairo unoshanda utumire kune maLED kuburikidza nawo. Vatongi vanosanganisira iyo Arduino, iyo inoshandiswa nevanhu vazhinji, uye iyo Raspberry Pi. Uchishandisa marongero awakaronga mudhiraivha, mutongi "anoudza" LED yega yega kuti inofanira kuva neruvara rwupi, kupenya kwakadii, uye kuti inofanira kugara kwenguva yakareba sei iri munzvimbo iyoyo.
Iyo yakabatanidzwa yedunhu (IC) inowanikwa muWS2812B LEDs inoita kuti zvikwanise kuti maLED ataure netambo imwe chete. Izvi zvinokutendera kuti utore huwandu hukuru hwemaLED kubva pane imwe pini pane yako controller. Kune matatu mapini pa LED mitsetse yesimba (+5V), pasi (GND), uye data (Din uye Dout). Kubatanidza simba uye mapini epasi kune tambo yako shuwa kuti inogamuchira simba, nepo pini yedata ichiigonesa kutaurirana nemutongi.
Kana iwe uchida kushandisa Arduino kudzora tambo inoda 5V yesimba, haufanirwe kuve nedambudziko kuita saizvozvo ne5V inobuda pabhodhi. Kune rimwe divi, kana iwe uchida kumhanya yako LED strip neRaspberry Pi kana ESP8266, iyo inotumira zvikwangwani pa 3.3V, iwe unozoda logic-level converter module kuti uchinje chiratidzo chedata kubva ku3.3V kuenda ku5V. Zviratidzo zvinotumirwa kubva kumidziyo iyi pa3.3V. Kunze kwekunge iwe waita izvi, iyo LED strip yaunoshandisa inogona kusashanda.
Ko Ose WS2813 Uye WS2812B Anoshandisa MaRaibhurari Mamwechete?
Ose ari maviri WS2813 neWS2812B anoshandisa maraibhurari akafanana. Iyi mitsetse miviri inoda kuti maraibhurari atorerwe asati agona kudzorwa kuti abudise anopenga emwenje e LED. Aya maraibhurari anotonga LED yega yega, achibvumira kugadzirwa kweakaomesesa mapatani. Nekudaro, mutongi ari mubvunzo anokanganisa kuwanikwa kwemaraibhurari chaiwo. Mazhinji emaraibhurari aya anotorwa pachena kubva painternet.
NeESP8266 yako uye Arduino zvishandiso, unogona kushandisa anotevera maraibhurari:
- fastLED
- Adafruit_Neopixel

- Kune raspberry pi, unogona kushandisa anotevera maraibhurari: Rpi_ws281x python raibhurari
Ko Simba Rinopihwa kuWS2812B Strip Richasiyana neWS2813 Strip?
Pakupenya kuzere, ese maLED anoda kutenderedza 60mA yazvino, saka WS2812B masisitimu anogona kushandisa iwo mamwe marudzi emagetsi masosi. Huwandu hwesimba hunodiwa hunogara hwakasiyana kubva kune imwe seti ye LED mitsetse kuenda kune inotevera. Kuti tambo yako irambe iri pakupenya kwayo, unozofanira kushandisa sosi yemagetsi inokwanisa kubata dhirowa iripo. Kugonesa tambo imwe chete ye60 LEDs pakupenya kwavo kwakanyanya, iwe unozoda simba sosi yakarongerwa kanenge 3.6A (60 LEDs x 60mA). Uchishandisa USB 2.0 port inopa 0.9A, unogona kumhanya zvakachengeteka mitsetse ye0.9A/0.06A = gumi nemashanu maLED.
Mitengo yeWS2813 Uye WS2812B LEDs Inofananidzwa Sei?
Icho chokwadi chekuti WS2813 inodhura kupfuura yakatangira haifanire kuuya sechishamiso. Kubva pane zvatakawana mukutsvaga kwedu, mutengo weWS2813 LED strip ungangoita 20% kupfuura iya yakatangira, iyo WS2812B. Musiyano wemutengo pakati peaya maviri ma LED mitsetse hauna kukura zvakanyanya. Kunyangwe iyo WS2813 yanga iri pamusika kwechinguva, zvishoma nezvishoma iri kuwedzera mukurumbira.
