Imigaragarire ya SPI ni iki? Nigute SPI ikora?

SPI igereranya interineti ya peripheri ya perifeli kandi, nkuko izina ryerekana, umurongo ukurikirana wa periferi. Motorola yasobanuwe bwa mbere kuri MC68hcxx-seriveri.Spi ni umuvuduko mwinshi, wuzuye-duplex, hamwe nimirongo ine yitumanaho gusa kuri chip ya chip, mugihe cyo kuzigama pin Isaha-yigihe, ad ihinduka, kandi hagati yububiko bwa digitale na Decoder yibimenyetso bya Digital.

SPI ifite ecran nini nubucakara. Sisitemu yitumanaho ya SPI igomba gushiramo kimwe (kandi kimwe gusa) Igikoresho cya Master nigikoresho kimwe cyangwa byinshi byabacakara. Igikoresho nyamukuru (shobuja) gitanga isaha, igikoresho cyumucakara (imbata), hamwe nimikorere ya spi, byose bitangizwa nigikoresho nyamukuru. Iyo ibikoresho byinshi byabacakara bibaho, bayoborwa nibimenyetso bya Chip.SPI ni duplex yuzuye, kandi spi ntabwo isobanura imipaka ntarengwa, kandi ishyirwa mubikorwa rusange rirashobora kugera cyangwa birenze MB.

Imigaragarire ya SPI ikoresha imirongo ine yikimenyetso cyo gushyikirana:

SDI (amakuru yinjira), SDO (Amakuru yo gusohoka), SCK (isaha), CS (Hitamo)

Miso:Igikoresho cyibanze cyinjiza / gusohoka PIN uhereye kubikoresho. PIN yohereza amakuru muburyo kandi yakira amakuru muburyo bukuru.

Mosi:Igikoresho cyibanze gisohoka / kwinjiza PIC uhereye kubikoresho. PIN yohereza amakuru muburyo nyamukuru kandi yakira amakuru muburyo.

Sclk:Ikimenyetso cyisaha yuruhererekane, cyakozwe nibikoresho nkuru.

CS / SS:Hitamo ibimenyetso bivuye mubikoresho, bigenzurwa nibikoresho nkuru. Irakora nka "Chip Guhitamo PIN", ihitamo igikoresho cyumucakara cyagenwe, yemerera igikoresho cyabigenewe kuvugana nigikoresho cyihariye cyumucakara wenyine kandi wirinde amakimbirane kumurongo wamakuru.

Mu myaka yashize, guhuza spi (interineti ya periferi ya plaiplaque) ikoranabuhanga ryumvikana) ikoranabuhanga ryumvikana na oled (bisohora diode) byerekana Diode) Iyerekana ryabaye ingingo yibanze murwego rwa Tech. SPI, izwiho imikorere yayo yo hejuru, ikoreshwa ryimbaraga nke, hamwe nigishushanyo mbonera cyoroshye, gitanga ikwirakwizwa ryibimenyetso bihamye byo kumeneka. Hagati aho, ecran yacyo, hamwe n'imitungo yabo yo kwiyitabira, itandukaniro rinini, kandi ureba ultrasi.
