He aha te mea SPI-atanga

I whakawhanakehia SPI-atanga e Motorola. I teie mahana, ko reira tetahi o te rongonui tino, e tika ana ki tona tere tiketike, me te tapatahi tino o te hunga katoa e kōrero ki te momo rangatū. I tua atu, he hoki SPI-atanga te parau tumu hononga. Hono mo'oní, SPI ko te arorau raraunga (ariki-pononga) i waenganui i ngā pūrere e rua rerekē. Kei te aufauraa i ngā āhuatanga ōkiko nui iti whakarongo ki te whakatinana i a ratou, kia rite ki te mea ratou, "i roto i te mau huru", e kore e whakarato reira he kawa taumata o raro. Ka taea e ia te kaihanga hanga te tahi mea o ratou.

SPI-atanga whakaahuatanga

Ko te arorau o taua pūrere ko te whakawhiti raraunga rangatū (moka i te moka). I roto i E wehea tenei tautuhinga me te pānui i roto i te wa e te tohu karaka motuhake i te pahi motuhake (i huaina "wā pahi" ranei "tukutahi"). Na roto i te wehenga te tikanga te e te raraunga tautuhinga me te tukanga pānui e wahi i runga i mata karaka ritenga hangaia i runga i te pahi. Ki te wehea mārama tenei i roto i te wa pānuitanga interlace me ngā tautuhinga, riro te reira taea ki te whakamahi i tetahi me te taua rēhita mō te fariiraa, me te whakawhitihia mōhiohio. Ko reira i raro i tenei parau tumu, a whakawhanakehia te SPI-atanga. Heoi, e kore e tu te whanaketanga o te hangarau tonu, e moni tawhiti nui o mahara e kore te whakaatu i tetahi raruraru, me te nuinga o nga whakaaro i te wāhi me te putanga rehita motuhake. Here i roto i te tono mai i whakaaro matou pehea te whakarite te atanga SPI te.

Whakaahuatanga o te mahi pūrere

Pūrere whakaputa ngātere karaka (mana) ki te wā pahi, he "ariki" (ariki). whakahaere ana tēnei pūrere te tukanga katoa o te utu raraunga, arā, whakatau ka ki te tīmata i te utu, ka ki te whakaoti, e hia nga paraire o whakawhiti kōrero, me te pera i runga i .. te pūrere tuarua whai wāhi i roto i te utu, ka karanga te "pononga." E kore te mea tenei pūrere i roto i tetahi ara pā te karaka pahi. Hoki te utu tonu-Matarua whakamahi (te tuku i roto i ngā tohutohu e rua wā kotahi) atanga SP- wha rārangi:

- Mosi - wāhi me te putanga o te pononga ariki. Te taha o tenei aho reira he tuku o ngā mōhiohio i te ope ki te kaiwhiwhi.

- MISO - ariki tāuru me te putanga "pononga." Na roto i tenei whakahaere e tango ariki raraunga i te pūrere pŭpŭ tauturu.

- SCLK - pahi karaka. Te taha o tenei raina, mahia te "mata" pūrere ngātere karaka.

- SS - kōwhiringa o "pononga." Ki tenei ariki waea whakahaere te wātū utu.

E whakawaeheretia taumata arorau-kore, me te uara ngaohiko kōwae i runga i te raraunga pahi (MISO me Mosi). Ko te SS tohu tohu te mutunga, me te timatanga o te Paremete o te utu mōhiohio. Nuinga maha ko reira te kōaro. tikanga o tēnei e i roto i te utu raraunga "ariki" pūrere me tāuta i runga i te raina SS taumata iti tohu, me i te mutunga utu o - tiketike. Ko te aroaro o te taumata-SS tuku taea ki te whakarite e rave rahi "pononga" whakaaro mā te whakamahi i te tohu karaka me te pahi raraunga kahore kawa atu. Heoi, ka he tika taua hononga ki te homai i te pūrere fariiraa i ia raina motuhake SS.
