Yintoni i-spi yobujongane? Isebenza njani i-SPI?

I-SPI imele i-Persial Persial Persion Act kunye, njengoko igama libonisa, i-interhel ye-risial riveral. I-Motorola yaqala ichazwe kwi-MC68HCXX-Seriveries.I-SPI sisikhawulezi esiphezulu, i-Depex egcwele iBhasi, i-synchronous ges, kwaye isebenzisa kuphela i-CHIP yePIN, egcina iPIN yeCHB, ebonelela ngokulula kwi-EEPROM, i-Flash, Iwotshi yexesha lokwenyani, i-AD Converter, naphakathi kweprosesa yomqondiso wedijithali kunye ne-digital yomqondiso wedijithali.

I-SPI inolwazi ezimbini kunye neendlela zekhoboka. Inkqubo yonxibelelwano ye-SPI kufuneka ibandakanye enye (kwaye inye kuphela)) yesazisi kunye nesixhobo esinye okanye ngaphezulu sekhoboka. Isixhobo esiphambili (inkosi) ibonelela ngewotshi, isixhobo sekhoboka (ikhoboka), kunye ne-spi umfanekiso we-SPI, oqaliswe sisixhobo esiphambili. Xa izixhobo zekhoboka ezininzi zikhona, zilawulwa yimiqondiso ye-chip.I-SPI yi-duppex egcweleyo, kwaye i-SPI ayichazi umda wesantya, kwaye ukuphunyezwa ngokubanzi kunokufikelela okanye kudlule i-10 Mbps.

Intsomi ye-SPI ngokubanzi isebenzisa imigca emine yemiqondiso yokunxibelelana:

I-SDI (ungeniso lwedatha), i-SDOE Imveliso yedatha), i-SCT (iwotshi), cs (khetha)

I-miso:Igalelo lesixhobo esiphambili / iPIN yePIN kwisixhobo. IPIN ithumela idatha kwimodi kwaye ifumana idatha kwimodi ephambili.

Mosi:Iziphumo zemveliso ephambili / iPIN ye-PIN kwifowuni. IPIN ithumela idatha kwimodi ephambili kwaye ifumana idatha kwimodi.

I-SCLK:I-Spial Stoct Stoct, iveliswe zizixhobo eziphambili.

I-CS / SS:Khetha umqondiso kwizixhobo, ulawulwa zizixhobo eziphambili. Isebenza njengePIN yePIN yaseChip, ekhetha isixhobo esichaziweyo, esivumela isixhobo esichaziweyo ukuba sinxibelelane nesixhobo esithile sekhoboka kuphela kwaye sithintele ukungqubana kumgca wedatha.

Kwiminyaka yakutshanje, indibaniselwano ye-SPI I-SPI, eyaziwa ngokuba yimpumelelo enkulu, ukusetyenziswa kwamandla ephantsi, kunye noyilo olulula lwezixhobo, lubonelela ngokudluliselwa kwesiginali kwimiboniso efunyenweyo. Ngeli xesha, izikrini ezinqabileyo, kunye neepropathi zabo zokuzibulala, imilinganiselo ephezulu yokuphambuka, ii-angles eziphezulu, kunye nezikrini ze-Ultra, ziya kuthatha indawo ye-LCD ye-Ultra, i-SCREED ye-SCD ye-SCRPON, imbi kakhulu, kunye nezixhobo ze-IOI.
