Imigaragarire ya SPI Niki? Nigute SPI ikora?

SPI igereranya Serial Periferique kandi nkuko izina ribigaragaza, urutonde rwa periferique. Motorola yasobanuwe bwa mbere kuri MC68HCXX ikurikirana.SPI ni umuvuduko mwinshi, wuzuye-duplex, bisi itumanaho ihuza, kandi ifata imirongo ine gusa kuri chip pin, ikiza pin ya chip, mugihe uzigama umwanya kumiterere ya PCB, itanga ibyoroshye, ikoreshwa cyane cyane muri EEPROM, FLASH, isaha nyayo, AD ihindura, no hagati ya signal ya digitale na decoder ya signal.

SPI ifite shobuja nuburyo bubiri. Sisitemu y'itumanaho ya SPI igomba gushiramo igikoresho kimwe (kandi kimwe gusa) igikoresho kimwe nibikoresho byinshi cyangwa byinshi byabacakara. Igikoresho nyamukuru (Umwigisha) gitanga isaha, igikoresho cyumucakara (Umucakara), hamwe na interineti ya SPI, byose bitangizwa nigikoresho nyamukuru. Iyo ibikoresho byinshi byabacakara bibaho, bayoborwa nibimenyetso bya chip.SPI ni duplex yuzuye, kandi SPI ntisobanura umuvuduko ntarengwa, kandi ishyirwa mubikorwa rusange rishobora kugera cyangwa kurenga 10 Mbps.

Imigaragarire ya SPI muri rusange ikoresha imirongo ine yerekana ibimenyetso:

SDI (Ibyinjira byinjira), SDO (Ibisohoka Data), SCK (Isaha), CS (Hitamo)

MISO:Igikoresho cyibanze cyinjiza / gisohoka pin kuva igikoresho. Ipine yohereza amakuru muburyo kandi yakira amakuru muburyo bukuru.

MOSI:Igikoresho cyibanze Ibisohoka / kwinjiza pin kuva kubikoresho. Ipine yohereza amakuru muburyo bukuru kandi yakira amakuru kuva muburyo.

SCLK:Ikimenyetso cyamasaha yuruhererekane, cyakozwe nibikoresho nyamukuru.

CS / SS:Hitamo ibimenyetso mubikoresho, bigenzurwa nibikoresho nyamukuru. Ikora nka "chip selection pin", ihitamo igikoresho cyabacakara cyagenwe, cyemerera igikoresho cyibanze kuvugana nigikoresho cyumucakara cyonyine kandi kikirinda amakimbirane kumurongo wamakuru.

Mu myaka yashize, guhuza ikoranabuhanga rya SPI (Serial Peripheral Interface) hamwe na OLED (Organic Light-Emitting Diode) ryabaye ikintu cyibanze mu nganda zikoranabuhanga. SPI, izwiho gukora neza, gukoresha ingufu nke, hamwe nibikoresho byoroshye, itanga ibimenyetso bihamye byohereza OLED yerekana. Hagati aho, ecran ya OLED, hamwe nubwiyumanganya bwayo, ibipimo bihabanye cyane, impande nini zo kureba, hamwe na ultra-thin ibishushanyo, bigenda bisimbuza ecran gakondo ya LCD, bigahinduka igisubizo cyerekanwe kuri terefone zigendanwa, kwambara, nibikoresho bya IoT.
