Koj puas paub SPI thiab DMX strip?

SPI (Serial Peripheral Interface) LED sawb yog hom digital LED sawb uas tswj cov LEDs ib leeg siv SPI kev sib txuas lus raws tu qauv. Thaum piv rau cov tsoos analog LED strips, nws muaj kev tswj ntau dua xim thiab ci. Cov hauv qab no yog qee qhov txiaj ntsig ntawm SPI LED strips:

1. Txhim kho cov xim raug: SPI LED strips muab cov xim zoo nkauj, uas tso cai rau cov khoom siv ntau yam xim.
2. Ceev refresh npaum li cas: SPI LED strips muaj ceev refresh tus nqi, uas txo flicker thiab txhim kho tag nrho cov duab zoo.
3. Txhim kho brightness tswj:SPI LED stripsmuaj kev tswj kom zoo-grained brightness, tso cai rau hloov maj mam hloov mus rau ib tug neeg LED brightness theem.
4. Kev hloov cov ntaub ntawv ceev dua: SPI LED strips tuaj yeem hloov cov ntaub ntawv ntawm tus nqi nrawm dua li cov qauv analog LED strips, tso cai rau kev hloov pauv rau cov zaub kom ua tau raws sijhawm.
5. Yooj yim rau kev tswj hwm: Vim tias SPI LED strips tuaj yeem tswj tau los ntawm microcontroller yooj yim, lawv yooj yim los ua ke rau hauv cov teeb pom kev zoo.

Txhawm rau tswj tus kheej LEDs, DMX LED strips siv DMX (Digital Multiplexing) raws tu qauv. Lawv muab cov xim ntau dua, ci ntsa iab, thiab lwm yam kev tswj hwm zoo dua li analog LED strips. Ntawm cov txiaj ntsig ntawm DMX LED strips yog:

1. Kev tswj kom zoo: DMX LED strips tuaj yeem tswj tau los ntawm lub siab DMX maub los, tso cai rau kev tswj xyuas meej ntawm qhov ci, xim, thiab lwm yam teebmeem.
2. Muaj peev xwm tswj tau ntau lub teeb pom kev zoo: DMX maub los tuaj yeem tswj ntau DMX LED strips tib lub sijhawm, ua kom teeb pom kev zoo teeb pom kev yooj yim.
3. Muaj kev cia siab rau: Vim tias cov teeb liab digital tsis tshua muaj kev cuam tshuam thiab teeb liab poob, DMX LED strips muaj kev ntseeg siab dua li cov qauv analog LED strips.
4. Txhim kho synchronization: Txhawm rau tsim cov teeb pom kev zoo sib xws, DMX LED strips tuaj yeem synchronized nrog rau lwm yam DMX tshaj teeb pom kev zoo xws li txav teeb thiab ntxuav teeb.
5. Qhov zoo tshaj plaws rau kev teeb tsa loj: Vim tias lawv muab qib siab ntawm kev tswj hwm thiab hloov tau yooj yim, DMX LED strips yog qhov zoo tagnrho rau kev teeb tsa loj xws li theem tsim khoom thiab cov teeb pom kev zoo vaj tsev.

Txhawm rau tswj tus kheej LEDs,DMX LED stripssiv DMX (Digital Multiplex) raws tu qauv, hos SPI LED strips siv Serial Peripheral Interface (SPI) raws tu qauv. Thaum piv rau analog LED strips, DMX strips muab kev tswj ntau dua xim, ci, thiab lwm yam teebmeem, qhov SPI strips yooj yim rau kev tswj thiab tsim rau me me installation. SPI strips yog nrov nyob rau hauv hobbyist thiab DIY tej yaam num, whereas DMX strips yog feem ntau siv nyob rau hauv kev teeb pom kev zoo daim ntaub ntawv.Tiv tauj pebkom paub meej ntxiv.
