Yintoni iSPI Interface? Isebenza njani iSPI?

I-SPI imele ujongano lweSerial Peripheral kwaye, njengoko igama licebisa, ujongano olulandelelanayo lweperipheral. I-Motorola yachazwa okokuqala kwi-MC68HCXX-series processors.I-SPI i-speed-speed, i-duplex epheleleyo, i-synchronous ibhasi yokunxibelelana, kwaye ithatha imigca emine kuphela kwi-chip pin, igcina i-pin ye-chip, ngelixa igcina indawo yokwakheka kwe-PCB, ibonelela ngokulula, isetyenziswa kakhulu kwi-EEPROM, i-FLASH, iwashi yexesha langempela, i-AD converter, kunye naphakathi kweprosesa yesignali yedijithali kunye ne-decoder signal yedijithali.

I-SPI ineendlela ezimbini zenkosi kunye nekhoboka. Inkqubo yonxibelelwano ye-SPI kufuneka ibandakanye enye (kunye nenye kuphela) isixhobo esiyintloko kunye nesixhobo esinye okanye ngaphezulu kwekhoboka. Isixhobo esiphambili (i-Master) sibonelela ngewotshi, isixhobo sekhoboka (Ikhoboka), kunye ne-SPI interface, zonke eziqaliswe sisixhobo esiphambili. Xa kukho izixhobo ezininzi zamakhoboka, zilawulwa ziimpawu zetshiphu ezihlukeneyo.I-SPI i-duplex epheleleyo, kwaye i-SPI ayichazi umda wesantya, kwaye ukuphunyezwa ngokubanzi kunokufikelela okanye kudlule i-10 Mbps.

Ujongano lweSPI lusebenzisa imigca yemiqondiso emine ukunxibelelana:

I-SDI (uNgeno lweDatha), i-SDO (imveliso yedatha), i-SCK (iClock), i-CS (Khetha)

MISO:Ungeniso lwesixhobo sokuqala/iphini yokukhupha kwisixhobo. I-pin ithumela idatha kwimodi kwaye ifumana idatha kwimodi ephambili.

MOSI:Imveliso yeSixhobo sokuqala/i-pin yokufaka kwisixhobo. I-pin ithumela idatha kwimodi ephambili kwaye ifumana idatha kwimodi.

SCLK:Isiginali yewotshi yothotho, eyenziwe sisixhobo esiphambili.

CS / SS:Khetha isignali kwisixhobo, esilawulwa sisixhobo esiphambili. Isebenza "njengepini yokukhetha i-chip", ekhetha isixhobo esicacisiweyo sekhoboka, sivumela isixhobo esiyintloko ukuba sinxibelelane nesixhobo esithile sekhoboka sodwa kwaye siphephe iingxabano kumgca wedatha.

Kwiminyaka yakutshanje, indibaniselwano ye-SPI (i-Serial Peripheral Interface) iteknoloji kunye ne-OLED (i-Organic Light-Emitting Diode) iziboniso ziye zaba yinto ekugxilwe kuyo kwi-tech industry. I-SPI, eyaziwa ngokusebenza kwayo okuphezulu, ukusetyenziswa kwamandla aphantsi, kunye noyilo olulula lwe-hardware, inika ukuhanjiswa kwesignali ezinzileyo kwimiboniso ye-OLED. Ngeli xesha, izikrini ze-OLED, ezineempawu zazo zokuzikhupha, umlinganiselo ophezulu wokuthelekisa, ii-engile zokujonga ngokubanzi, kunye noyilo oluncinci kakhulu, ziya zithatha indawo yezikrini ze-LCD zendabuko, zibe sisisombululo esithandwayo sokubonisa ii-smartphones, izinto ezinxitywayo, kunye nezixhobo ze-IoT.
