Yintoni i-DMX512-SPI idikhowuda?

Isixhobo esiguqula imiqondiso yolawulo ye-DMX512 ibe ziimpawu ze-SPI (Serial Peripheral Interface) saziwa ngokuba yi-DMX512-SPI decoder. Ukulawula izibane zeqonga kunye nezinye izixhobo zokuzonwabisa zisebenzisa iprotocol eqhelekileyo ye-DMX512. I-synchronous serial interface, okanye i-SPI, lujongano oludumileyo lwezixhobo zedijithali ezifana ne-microcontrollers. Ukusebenzisa izixhobo ezine-SPI, ezifana nezibane ze-pixel ze-LED okanyeimicu yedijithali ye-LED, Iimpawu zokulawula i-DMX zinokuguqulelwa kwiimpawu ze-SPI usebenzisa i-decoder ye-DMX512-SPI. Oku kwenza kube lula ukulawula ukukhanya ngakumbi kwaye ngokuyilayo ngexesha lemidlalo kunye neziganeko.

Uya kufuna oku kulandelayo ukuqhagamshela umtya we-LED kwidikhowuda ye-DMX512-SPI:

Uluhlu lwe-LED: Qinisekisa ukuba umcu wakho we-LED usebenzisa zombini unxibelelwano lwe-SPI kunye nolawulo lwe-DMX. Ezi ntlobo zemicu ye-LED idla ngokuba neesekethe ezidityanisiweyo (ICs) ezakhelwe ukulawula ipixel nganye.

Iimpawu zokulawula i-DMX ziguqulelwa kwiimpawu ze-SPI ukuba i-strip ye-LED inokutolika nge-decoder ye-DMX512-SPI. Yenza ukuba idikhowuda ikwazi ukuthwala inani elifunekayo leepikseli kwaye iyahambelana nomcu wakho we-LED.

Umlawuli we-DMX: Ukuhambisa iimpawu zolawulo kwi-decoder ye-DMX512-SPI, uya kufuna umlawuli we-DMX. Abalawuli be-DMX banokuba zii-consoles ze-hardware, abalawuli abasekwe kwisoftware, okanye usetyenziso lweselula.

Idikhowuda ye-DMX512-SPI kunye neenkqubo zoqhagamshelo lomcu we-LED zezi zilandelayo:

Qinisekisa ukuba i-DMX512-SPI idekhowuda imiselwe kwaye ilungiselelwe ukusetyenziswa nomlawuli wakho we-DMX.

Sebenzisa intambo eqhelekileyo ye-DMX ukudibanisa imveliso ye-DMX yomlawuli we-DMX kwigalelo le-DMX ye-DMX512-SPI decoder.

Qhagamshela imveliso ye-SPI ye-DMX512-SPI decoder's kwigalelo le-SPI yestrip ye-LED. I-decoder ethile kunye ne-strip ye-LED inokufuna udibaniso olwahlukileyo lwewotshi (CLK), idatha (DATA), kunye neengcingo zomhlaba (GND).

Qhagamshela idikhowuda ye-DMX512-SPI, umtya we-LED, kunye nobonelelo lwamandla. Qinisekisa ukuba zombini izixhobo zifumana i-voltage efanelekileyo kunye nekhoyo ngoku kubonelelo lwamandla. Ukudibanisa amandla, bambelela kwiingcebiso zomenzi.

Ukuthumela imiqondiso yolawulo ye-DMX ukusuka kumlawuli ukuya kwidikhowuda linyathelo lokugqibela lokuvavanya ukuseta. Idikhowuda iya kuguqula imiqondiso ye-DMX ibe ziimpawu zeSPI eziza kusetyenziselwa ukusebenzisa iipikseli zomcu we-LED.

Kubalulekile ukukhumbula ukuba iinkqubo ezithile kunye noqhagamshelo lunokwahluka ngokusekwe kuhlobo kunye nebhrendi ye-DMX512-SPI idikhowuda kunye nomcu we-LED. Ukufumana imiyalelo echanekileyo, soloko ubhekisa kwisikhokelo somsebenzisi kunye nezinye izinto ezibonelelwa ngabaenzi.

I-Mingxue LED ine-COB / CSP, i-Neon strip, i-voltage ephezulu kunye newasha eludongeni,Qhagamshelana nathikwaye sinokukuthumela iinkcukacha ezithe kratya malunga nezibane ze-LED strip.
