Iyini idekhoda ye-DMX512-SPI?

Idivayisi eguqula amasiginali okulawula i-DMX512 ibe amasiginali we-SPI (Serial Peripheral Interface) yaziwa njengedekhoda ye-DMX512-SPI. Ukulawula izibani zasesiteji nezinye izinto zokuzijabulisa kusebenzisa iphrothokholi evamile ye-DMX512. I-synchronous serial interface, noma i-SPI, iyisixhumi esibonakalayo esidumile samadivayisi edijithali afana nama-microcontrollers. Ukusebenzisa amadivayisi anamandla e-SPI, njengezibani zephikseli ze-LED nomaimichilo yedijithali ye-LED, amasiginali okulawula i-DMX angahunyushelwa kumasiginali we-SPI kusetshenziswa idekhoda ye-DMX512-SPI. Lokhu kwenza kube nokwenzeka ukuphatha ukukhanya ngokuyinkimbinkimbi nangokudala ngesikhathi sokudlalwa nemicimbi.

Uzodinga okulandelayo ukuze uxhume umucu we-LED kusikhikhoda se-DMX512-SPI:

Umugqa we-LED: Qinisekisa ukuthi umugqa wakho we-LED usebenzisa kokubili ukuxhumana kwe-SPI nokulawula kwe-DMX. Lezi zinhlobo zemigqa ye-LED ngokuvamile inamasekhethi ahlanganisiwe (ICs) akhelwe ngaphakathi ukuze alawule iphikseli ngayinye.

Amasiginali okulawula i-DMX aguqulelwa kuzimpawu ze-SPI umugqa we-LED ongawuhumusha ngedekhoda ye-DMX512-SPI. Yenza ukuthi idikhoda ikwazi ukuthwala inani elidingekayo lamaphikseli futhi ihambisane nomugqa wakho we-LED.

Isilawuli se-DMX: Ukuze ulethe amasiginali okulawula kusikhikhoda se-DMX512-SPI, uzodinga isilawuli se-DMX. Izilawuli ze-DMX zingaba amakhonsoli ezingxenyekazi zekhompiyutha, izilawuli ezisuselwe kwisoftware, noma izinhlelo zokusebenza zeselula.

Idekhoda ye-DMX512-SPI kanye nezinqubo zokuxhuma komcu we-LED zimi kanje:

Qinisekisa ukuthi isikhiphi sekhodi se-DMX512-SPI simisiwe futhi silungiselwe ukusetshenziswa nesilawuli sakho se-DMX.

Sebenzisa ikhebuli ye-DMX evamile ukuze uxhume okukhiphayo kwe-DMX yesilawuli se-DMX kokokufaka kwe-DMX kwedekhoda ye-DMX512-SPI.

Xhuma okukhiphayo kwe-SPI yedekhoda ye-DMX512-SPI kokokufaka kwe-SPI yomugqa we-LED. Idekhoda ethile kanye nomugqa we-LED kungase kudinge ukuxhumana okuhlukile kwewashi (CLK), idatha (DATA), nezintambo eziphansi (GND).

Xhuma idekhoda ye-DMX512-SPI, umucu we-LED, kanye nokunikezwa kwamandla. Qinisekisa ukuthi zombili izisetshenziswa zithola i-voltage efanele kanye nezamanje kusukela ekunikezeni amandla. Ukuze uthole ukuxhumeka kwamandla, landela izincomo zomkhiqizi.

Ukuthumela amasignali okulawula i-DMX ukusuka kusilawuli kuya kusikhikhoda kuyisinyathelo sokugcina sokuhlola ukusetha. Idekhoda izoguqula amasignali e-DMX abe amasignali e-SPI azosetshenziselwa ukusebenzisa amaphikseli e-LED angawodwana.

Kubalulekile ukukhumbula ukuthi izinqubo ezithile nokuxhumana kungase kwehluke ngokusekelwe ohlotsheni nomkhiqizo wedekhoda yakho ye-DMX512-SPI kanye nomugqa we-LED. Ukuze uthole imiyalelo efanele, hlala ubheka igayidi yomsebenzisi nezinye izinto ezinikezwe abakhi.

I-Mingxue LED ine-COB/CSP, i-Neon strip, i-voltage ephezulu kanye newasha yodonga,Xhumana nathifuthi singakuthumelela imininingwane eyengeziwe mayelana nezibani ze-strip ze-LED.
