Interface ya SPI ni iki? SPI ikora ite?

SPI isobanura Serial Peripheral interface, kandi nk'uko izina ribigaragaza, ni serial peripheral interface. Motorola yabanje gusobanurwa kuri MC68HCXX-series processors zayo.SPI ni bisi y'itumanaho yihuta cyane, yuzuye kandi ihuza ibintu bibiri, kandi ifata imirongo ine gusa kuri pin ya chip, ikarinda pin ya chip, mu gihe izigama umwanya wo gushyiraho PCB, ikanatanga uburyo bworoshye, bukoreshwa cyane cyane muri EEPROM, FLASH, isaha nyayo, AD converter, no hagati ya poroseseri y'ibimenyetso bya digitale na decoder y'ibimenyetso bya digitale.

SPI ifite uburyo bubiri bwa master na slave. Sisitemu y'itumanaho ya SPI igomba kuba irimo igikoresho kimwe (kandi kimwe gusa) cya master hamwe n'igikoresho kimwe cyangwa byinshi bya slave. Igikoresho nyamukuru (Master) gitanga isaha, igikoresho cya slave (Slave), na interface ya SPI, byose bitangirwa n'igikoresho nyamukuru. Iyo hari ibikoresho byinshi bya slave, bicungwa n'ibimenyetso bya chip.SPI ni umuvuduko wuzuye, kandi SPI ntabwo igena umuvuduko ntarengwa, kandi ishyirwa mu bikorwa rusange rishobora kugera cyangwa rikarenga 10 Mbps.

Interineti ya SPI muri rusange ikoresha imirongo ine y'ibimenyetso mu gutumanaho:

SDI (Kwinjiza Amakuru), SDO (Gusohora Amakuru), SCK (Isaha), CS (Hitamo)

MISO:Agasanduku k'ibanze k'igikoresho k'ibanze k'injira/isohorwa kivuye muri icyo gikoresho. Agasanduku kohereza amakuru muri ubwo buryo kandi kakakira amakuru muri ubwo buryo bw'ibanze.

MOSI:Agasanduku k'ibanze k'igikoresho gisohoka/agasanduku k'injira kavuye muri icyo gikoresho. Agasanduku kohereza amakuru mu buryo bw'ibanze kakakira amakuru aturutse muri ubwo buryo.

SCLK:Ikimenyetso cy'isaha gikoreshwa mu buryo bw'uruhererekane, gitangwa n'ibikoresho by'ingenzi.

CS / SS:Hitamo ikimenyetso kiva mu bikoresho, kigenzurwa n'ibikoresho by'ingenzi. Gikora nk'agapira ko guhitamo igikoresho cyagenwe, gahitamo igikoresho cyagenwe, gatuma igikoresho cyambere gishobora kuvugana n'igikoresho cyagenwe cyonyine kandi kikarinda amakimbirane ku murongo w'amakuru.

Mu myaka ya vuba aha, guhuza ikoranabuhanga rya SPI (Serial Peripheral Interface) na OLED (Organic Light-Emitting Diode) byabaye ingenzi mu nganda z'ikoranabuhanga. SPI, izwiho gukora neza cyane, gukoresha ingufu nke, no gushushanya ibikoresho byoroshye, itanga uburyo bwo kohereza ibimenyetso bya OLED mu buryo buhamye. Hagati aho, ecran za OLED, zifite imiterere yazo ubwayo, ingano nini yo kugaragara, inguni nini zo kureba, n'imiterere yoroheje cyane, zigenda zisimbura ecran za LCD zisanzwe, ziba igisubizo cyiza cyo kwerekana ecran kuri terefone zigendanwa, ibikoresho byambarwa, n'ibikoresho bya IoT.
