Chii chinonzi SPI Interface? SPI Inoshanda Sei?

SPI inomirira Serial Peripheral interface uye, sekureva kunoita zita, serial peripheral interface. Motorola yakatanga kutsanangurwa pane yayo MC68HCXX-series processors.SPI ndeyekumhanya-mhanya, yakazara-duplex, inopindirana yekufambisa bhazi, uye inongogara mitsara mina pane chip pin, ichichengetedza pini yechip, ichichengetedza nzvimbo yePCB dhizaini, ichipa nyore, inonyanya kushandiswa muEEPROM, FLASH, chaiyo-nguva wachi, AD converter, uye pakati pedhijitari siginecha processor uye digital sign decoder.

Iyo SPI ine maviri tenzi uye muranda modes. Iyo SPI yekutaurirana sisitimu inoda kusanganisa imwe (uye imwe chete) tenzi mudziyo uye imwe kana anopfuura maturusi evaranda. Iyo huru mudziyo (Tenzi) inopa wachi, mudziyo wenhapwa (Muranda), uye SPI interface, izvo zvese zvinotangwa neiyo huru mudziyo. Kana akawanda evaranda maturusi aripo, anotungamirwa neakasiyana chip masaini.Iyo SPI izere-duplex, uye iyo SPI haitsananguri yekumhanyisa muganho, uye kuita kwakawanda kunogona kusvika kana kutopfuura 10 Mbps.

Iyo SPI interface inowanzo shandisa mitsetse mina yekutaurirana:

SDI (Data Kupinda), SDO (Data kubuda), SCK (Clock), CS (Sarudza)

MISO:Yekutanga mudziyo wekuisa/pini yekuburitsa kubva muchishandiso. Iyo pini inotumira data mumodhi uye inogamuchira data mune huru modhi.

MOSI:Primary Device Output/pini yekupinda kubva muchishandiso. Iyo pini inotumira data mune huru modhi uye inogamuchira data kubva kumodhi.

SCLK:Seri wachi chiratidzo, inogadzirwa nemichina mikuru.

CS / SS:Sarudza chiratidzo kubva kumidziyo, inodzorwa nemidziyo mikuru. Inoshanda se "pini yekusarudza chip", iyo inosarudza iyo yakataurwa muranda mudziyo, ichibvumira tenzi mudziyo kutaurirana neimwe yemuranda mudziyo wega uye kudzivirira kukakavara pamutsetse wedata.

Mumakore achangopfuura, musanganiswa weSPI (Serial Peripheral Interface) tekinoroji uye OLED (Organic Chiedza-Emitting Diode) inoratidza yave nzvimbo yakatarisana muindasitiri yetekinoroji. SPI, inozivikanwa nekunyanya kushanda kwayo, yakaderera simba rekushandisa, uye yakapusa dhizaini dhizaini, inopa yakagadzika chiratidzo chekufambisa kweOLED kuratidza. Zvichakadaro, zviratidziro zveOLED, zvine hunhu hwazvo hwekuzvimirira, kusiyanisa kwakakura, makona ekuona, uye magadzirirwo ekupedzisira-mutete, ari kuwedzera kutsiva echinyakare maLCD skrini, achiva mhinduro inosarudzika yekuratidzira yemafoni, zvinopfeka, uye zvishandiso zveIoT.
