He aha ka mea e pili ai i ka spi? Pehea e hana aiʻo Spi?
Kūlikeʻo Spi no nā interface o serial a me, e like me ka mea i manaʻoʻia, heʻano maʻamau serial. Ua wehewehe muaʻiaʻo Motorola ma kāna mau papa hana hana mc68hcxxx-series.ʻO SPI kahi wikiwiki kiʻekiʻe, piha-Duplex ʻO ka CLOCK CLOCK, AD Converter, a ma waena o ke kaʻina hana hōʻailona hōʻailona a me ka decilii digital hōʻailona hōʻailona.
ʻElua mau haku spi a me nā mody slave. Pono kahi'ōnaehana kamaʻilio SPI e hoʻohui i hoʻokahi (a hoʻokahi wale nō) ma luna o nā mea hana a me hoʻokahi a iʻole nā mea i loaʻa i nā mea hana. Hāʻawi ka mea hana nui I ka wā e loaʻa ai nā mea i loaʻa i nā mea hana he nui, ua hoʻokeleʻia lākou e nā hōʻailona hōʻailona chip.ʻO ka Spi ka piha piha,ʻaʻole e wehewehe i kahi palena wikiwiki, a hiki i ka hopena maʻamau ke hiki i ka maʻamau ke hiki aku ai aʻoi aku paha ma mua o 10 mau mbps.
Hoʻohanaʻo ka Inter Sentface i nā laina hōʻailonaʻehā no ka kamaʻilioʻana:
SDI (Ke komoʻikepili)
Misi:ʻO ka mea hana helu helu helu / Output PIN mai ka hāmeʻa. Hoʻouna ka PIN i kaʻikepili i keʻano a loaʻa i kaʻikepili i keʻano nui.
Mihi:ʻO ka mea hana mua / input PIN mai ka polokalamu. Hoʻouna ka PIN i kaʻikepili i keʻano nui a loaʻa i kaʻikepili mai keʻano.
Sclk:ʻO ka hōʻailona hōʻailona scall clock, i hanaʻia e nā pono nui.
Cs / ss:Koho i ka hōʻailona palapala mai nā lako hana, hoʻokeleʻia e nā mea nui. E hana ana ia e like me kahi "chip koho koho", e koho i ka mea i kohoʻia, eʻae ana i ka mea e pili ana i ka'ōnaehana SCECTER ma ka Pūnaewele Pūnaewele.
I nā makahiki i hala iho nei, ka hui pūʻana o SPI (Serial Meripheral Interface)ʻenehana a me keʻano o keʻano o keʻano. ʻO SPI, Uaʻikeʻia no kona mana kiʻekiʻe loa, haʻahaʻa haʻahaʻa, a me ka hoʻolālā maʻalahi loa, e hāʻawi i nā hōʻailona hōʻailona koi no ka hoʻolahaʻana i nā hōʻike hōʻailona. ʻO ke kumu, nā kiʻi kiʻi, me kā lākou waiwai pilikino, keʻano o nā kihi kiʻekiʻe, a me nā mea nānā nani, a me nā mea hana maikaʻi loa.
