Yini isikhombimsebenzisi se-SPI? I-SPI isebenza kanjani?

I-SPI imele isikhombimsebenzisi se-serial peripheral futhi, njengoba igama libonisa, isikhombimsebenzisi se-serial peripheral. I-Motorola yachazwa okokuqala kumaprosesa wayo we-MC68HCCXX-uchungechunge.I-SPI iyisivinini esiphakeme, i-duplex egcwele, ibhasi lokuxhumana elivumelanayo, futhi ihlala kuphela imigqa emine kwi-chip pin, ngenkathi ukonga isikhala se-PCB ukwakheka, ukuhlinzeka lula ku-EEPROM, i-Flash, Iwashi lesikhathi sangempela, isiguquli se-ad, naphakathi kweprosesa yesiginali yedijithali ne-decoder yesiginali yedijithali.

I-SPI inezindlela ezimbili zenkosi nezigqila. Uhlelo lokuxhumana lwe-SPI ludinga ukufaka idivaysi eyodwa (futhi eyodwa kuphela) nedivayisi eyi-master kanye namadivayisi esigqila esisodwa. Idivayisi eyinhloko (Master) ihlinzeka ngewashi, idivaysi yesigqila (inceku), kanye nesibonisi se-SPI, konke okuqalwa yidivayisi enkulu. Lapho kuvela amadivayisi amaningi ngezigqila, aphethwe amasiginali we-chip afanele.I-SPI iyi-dumplex ephelele, futhi i-SPI ayichazi umkhawulo wejubane, futhi ukusetshenziswa okujwayelekile kungavame ukufinyelela noma kudlule i-10 MBP.

I-interface ye-SPI ngokuvamile isebenzisa imigqa emine yesiginali yokuxhumana:

I-SDI (Ukungena kwedatha), SDO (okukhipha idatha), i-SCK (CLOCK), CS (Khetha)

I-MISO:Ukufakwa Kwedivayisi Okuyisisekelo / Ukukhishwa Kwedivayisi kusuka kudivayisi. I-PIN ithumela idatha kwimodi futhi ithola idatha kwimodi enkulu.

UMosi:Ukukhishwa okuyisisekelo kwedivaysi / i-PIN yokufaka kusuka kudivayisi. I-PIN ithumela idatha kwimodi enkulu futhi ithola idatha kwimodi.

I-SCLK:Isiginali yewashi ye-serial, ekhiqizwa imishini esemqoka.

CS / SS:Khetha isinali kusuka kumathuluzi, alawulwa yimishini esemqoka. Isebenza njenge- "Chip Ukukhetha Iphinikhodi", ekhetha idivaysi ecacisiwe yenceku, evumela idivaysi enkulu ukuxhumana nedivaysi ethile yesigqila eyedwa futhi ugweme izingxabano kulayini wedatha.

Eminyakeni yamuva nje, inhlanganisela ye-SPI (i-serial peripheral interface) ubuchwepheshe kanye ne-oled (i-organic ukukhanya - i-diode ye-diode yokukhanya okukhanyayo) sekuyindawo yokugxila embonini yezobuchwepheshe. I-SPI, eyaziwa ngokusebenza kwayo okuphezulu, ukusetshenziswa kwamandla okuphansi, kanye nokwakheka okulula kwehardware, kunikeza ukuhanjiswa okuzinzile kwesiginali ukuze kuboniswe ama-oled. Ngaleso sikhathi, izikrini ezinama-oled, ngezindawo zazo ezizikhangayo, isilinganiso esiphakeme kakhulu, ukubheka kakhulu ama-engeli, nemiklamo ye-ultra-mncane, iba yisixazululo esibukhombisa se-LCD, izintambo ezithandwayo zama-Smartphones, ezigqoke, kanye namadivayisi we-iot.
