Yintoni i-SPI Interface? Isebenza njani i-SPI?

I-SPI imele i-Serial Peripheral interface kwaye, njengoko igama lisitsho, i-serial peripheral interface. I-Motorola yaqala ukuchazwa kwiiprosesa zayo ze-MC68HCXX-series.I-SPI yibhasi yonxibelelwano ekhawulezayo, egcwele kabini, ehambelanayo, kwaye ithatha imigca emine kuphela kwiphini yetship, igcina iphini yetship, ngelixa igcina indawo yoyilo lwePCB, ibonelela ngokulula, esetyenziswa kakhulu kwi-EEPROM, iFLASH, iwotshi yexesha langempela, i-AD converter, kunye naphakathi kweprosesa yesignali yedijithali kunye ne-digital signal decoder.

I-SPI ineendlela ezimbini ze-master kunye ne-slave. Inkqubo yonxibelelwano ye-SPI kufuneka iquke isixhobo esinye (esinye kuphela) esiyintloko kunye nesixhobo esinye okanye ezingaphezulu ze-slave. Isixhobo esiphambili (i-Master) sinika iwotshi, isixhobo se-slave (i-Slave), kunye ne-interface ye-SPI, zonke eziqalwa sisixhobo esiphambili. Xa kukho izixhobo ezininzi ze-slave, zilawulwa ziimpawu ze-chip ezifanelekileyo.I-SPI yi-full-duplex, kwaye i-SPI ayichazi umda wesantya, kwaye ukusetyenziswa ngokubanzi kunokufikelela okanye kudlule i-10 Mbps.

I-interface ye-SPI ngokubanzi isebenzisa imigca emine yesignali yokunxibelelana:

I-SDI (Ukungena kwedatha), i-SDO (Ukuphuma kwedatha), i-SCK (Iwotshi), i-CS (Khetha)

I-MISO:Iphini yokufaka/yokukhupha yesixhobo esiphambili esivela kwisixhobo. Iphini ithumela idatha kwimowudi kwaye ifumane idatha kwimowudi ephambili.

UMOSI:Iphini yokukhupha/yokufaka yesixhobo esiphambili kwisixhobo. Iphini ithumela idatha kwimowudi ephambili kwaye ifumana idatha kwimowudi.

I-SCLK:Isignali yewotshi ye-serial, eveliswa zizixhobo eziphambili.

I-CS / SS:Khetha isignali kwisixhobo, esilawulwa sisixhobo esiphambili. Sisebenza njenge "chip selection pin", ekhetha isixhobo esichaziweyo sekhoboka, ivumela isixhobo esiyintloko ukuba sinxibelelane nesixhobo esithile sekhoboka sodwa kwaye siphephe iingxabano kumgca wedatha.

Kwiminyaka yakutshanje, indibaniselwano yetekhnoloji ye-SPI (Serial Peripheral Interface) kunye ne-OLED (Organic Light-Emitting Diode) displays ibe yeyona nto iphambili kushishino lwetekhnoloji. I-SPI, eyaziwa ngokusebenza kwayo kakuhle, ukusetyenziswa kwamandla aphantsi, kunye noyilo olulula lwehardware, ibonelela ngokudluliselwa kwesignali okuzinzileyo kwi-OLED displays. Okwangoku, izikrini ze-OLED, ezineempawu zazo ezizikhuphayo, ii-high contrast ratios, ii-wide viewing engile, kunye noyilo oluncinci kakhulu, ziya zithatha indawo yezikrini ze-LCD zemveli, zibe sisisombululo esithandwayo sokubonisa kwiifowuni eziphathwayo, izixhobo ezinxitywayo, kunye nezixhobo ze-IoT.
