Chii chinonzi spi interface? Inoshanda sei spi?

Spi inomira ye serial peripheral interface uye, sezita rinoratidza, serial partipheral interface. Motorola yakatanga kutsanangurwa pane yayo mc68hcxx-series processors.Spi ndeyekumhanya-simple-yakazara-duplex, synchronous connection yebhazi, uye inochengetedza pini yePCB chimiro, ichiruramisa, inonyanya kushandiswa muEeprom, Flash, Chaiyo-nguva wachi, ad inoshandura, uye pakati peiyo dijitari chiratidzo processor uye digital chiratidzo decoder.

Iyo spi ine tenzi maviri uye madzishe marefu. Iyo Spi yekutaurirana system inoda kusanganisira imwe (uye imwe chete) master kifaa uye imwe kana zvimwe zvishandiso zvemuranda. Chishandiso chikuru (tenzi) chinopa wachi, mudziyo wevaranda (muranda), uye iyo spi interface, iyo yese yakatangwa nechishandiso chikuru. Kana zvishandiso zvevaranda zvevaranda zviripo, ivo vanotungamirirwa nezviratidziro zvechipesimba.Iyo spi ndeye yakazara-duplex, uye spi haina kutsanangura muganho wekumhanya, uye kushandiswa kwakawanda kunogona kuwanzosvika kana kutopfuura 10 MBPS.

Iyo Spi interface inowanzoshandisa mitsara ina yemasangano ekutaurirana:

SDI (yekupinda data), Sdo (Data Exput), Sck (Clock), CS (Sarudza)

Miso:Primary mudziyo wekushandisa / kubuda pini kubva mudziyo. Iyo pini inotumira data mune iyo mode uye inogamuchira data mumamiriro makuru.

Mosi:Primary mudziyo kubuda / input pini kubva kune mudziyo. Iyo pini inotumira data mumamiriro makuru uye inogamuchira data kubva kune iyo mode.

Sclk:Seria wachi chiratidzo, inogadzirwa nemidziyo mikuru.

CS / SS:Sarudza chiratidzo kubva kumidziyo, inodzorwa nemidziyo mikuru. Izvo zvinoshanda se "chip Sarudzo chePIN", iyo inosarudza iyo yakatarwa muranda

Mumakore achangopfuura, musanganiswa weSpiel (Serial Peripherel Interface) Tekinoroji uye Oled (organic Light-Endting Diode) Kuratidzira kwave kuita nzvimbo yeTech indasitiri. Spi, inozivikanwa nekubudirira kwayo kukuru, kusarudzika kwemagetsi, uye nyore hardware dhizaini, inopa kugadzikana kusagadzikana chiratidzo chekuratidzira kwechokwadi. Zvichakadaro, zvakadaira zvikwangwani zvavo, zvakakwirira zvemaonero, uye zvakakwirira zvekuona makona, uye kuwanda-kutadza kutsiva echinyakare eLCD skrini
