Khipha ku-internet PC SPI Interface Product

Lo mhlahlandlela uhlola okungcono kakhulu Imikhiqizo ye-PC SPI Interface Kuyatholakala, kucatshangelwa izici ezifana nesivinini, ukuhambisana, ukusebenziseka kalula, kanye nokufaneleka kohlelo lokusebenza. Singena ezigabeni ezahlukahlukene zomkhiqizo, ukugqamisa izici ezibalulekile futhi sikusize ukhethe isisombululo esifanele sezidingo zakho. Funda ngezinto ezahlukahlukene zokuxhumana ze-SPI futhi uthole ukuthi ungakhetha kanjani okulungile Umkhiqizo we-PC SPI Interface ngephrojekthi yakho. Sizophinde sithinte ukucatshangelwa okubucayi kokuqaliswa ngempumelelo.

Ukuqonda isikhombimsebenzisi se-SPI

Yini i-SPI?

I-SPI (isikhombimsebenzisi se-serial peripheral) yibhasi lokuxhumana elivumelanayo elisetshenziselwe ukuxhumana okufushane, ikakhulukazi ezinhlelweni ezishumekiwe. Isixhumi esibonakalayo esine-wire esinikeza indlela elula nokho ephumelelayo yokudlulisa idatha phakathi kwe-microcontroller namadivayisi ahlukahlukene. Ukuthandwa kwaso kuvela kalula kokusebenziseka kwayo, isivinini esikhulu, nezindleko eziphansi kakhulu. Ukuqonda izinkampani ze-SPI zibalulekile lapho ukhetha a Umkhiqizo we-PC SPI Interface.

Izisekelo zokuxhumana ze-SPI

Izinto ezibalulekile zokuxhumana ze-SPI zifaka i-mosi (master ngaphandle kwenceku), i-miso (master in isigqila ngaphandle), i-SCK (iwashi le-serial), kanye ne-SS (inceku)). Idivayisi enkulu ilawula isiginali yewashi futhi iqala ukuxhumana namadivayisi esigqila. Idivayisi ngayinye yenceku inomugqa ohlukile we-SS, okwenza i-Master ikwazi ukuxhumana nezigqila eziningi ngasikhathi sinye.

Ukukhetha umkhiqizo we-PC SPI we-PC SPI

Izici okufanele zicatshangelwe

Ukukhetha okulungile Umkhiqizo we-PC SPI Interface Kuya ngezinto eziningana, kufaka phakathi izidingo zesilinganiso sedatha, inani lamadivayisi okufanele lixhunywe, kanye nezinga lokusekelwa kwesoftware elidingekayo. Cabanga ukuthi ngabe udinga ukudluliswa kwedatha okuphezulu, amakhono wesiteshi esiningi, noma imitapo yolwazi eqondile yokuhlanganiswa komthungo ezinhlelweni zakho ezikhona.

Izinhlobo zemikhiqizo ye-PC SPI Interface

Izinhlobo eziningana ze Imikhiqizo ye-PC SPI Interface zikhona, kudlalwe izidingo ezihlukile. Lokhu kufaka phakathi:

• Abaguquli be-USB-to-SPI: Lokhu kuhlinzeka ngendlela elula yokusebenzisa amadivaysi e-SPI ane-PC ngechweba le-USB. Zivame ukuba ngumsebenzisi futhi zidinga ukusetha okuncane.
• Abalawuli be-PCI / PCIE SPI: Okwezinhlelo zokusebenza eziphezulu ezifuna amanani emali esheshayo kanye ne-bandwidth enkulu, abalawuli be-PCIE-based SPI bayakhethwa.
• Abahlaziyi be-Logic nge-SPI decoding: Lawa mathuluzi avumela ukuhlaziya okuphelele kokuxhumana kwe-SPI, kusiza ukulungisa iphutha nokuxazulula inkinga. Bangaphezulu kwezicelo eziyinkimbinkimbi.
• Amabhodi akhethekile wokuthuthuka: Amabhodi athile okuthuthuka ahlanganisa izindawo zokuhlangana ze-SPI, enikeza indawo ephelele yokuthuthuka ukuze uhlolwe ngokushesha nokuhlolwa.

Izincomo zomkhiqizo we-PC SP EPP

Ngenkathi izincomo zomkhiqizo eziqondile zidinga ukucatshangelwa kwezidingo zakho ngazinye kanye nesabelomali, nansi ukubuka konke okujwayelekile ukuqondisa ucwaningo lwakho. Njalo hlola imininingwane yomenzi yolwazi olusha kakhulu.

Khumbula ucwaninga kahle umkhiqizo ngamunye ukuze uqinisekise ukuhambisana nezidingo zakho ezithile ze-hardware nezidingo zesoftware ngaphambi kokuthenga.

Amasu we-SPI athuthukile nokuxazulula inkinga

Ukuphatha Izigqila eziningi

Ukuphatha kahle amadivayisi amaningi we-SPI Perve adinga ukuhlela ngokucophelela. Idivaysi eyi-Master kufanele ilawula kahle imigqa ye-SANVE SLANE (SS) ukubhekana nedivayisi ngayinye ngawodwana. Lokhu kuvame ukubandakanya ukusebenzisa ukukhohlisa noma ukubhaliswa kokubhalisa ngaphakathi kwesoftware yakho.

Ukuxazulula inkinga ngezinkinga ezijwayelekile ze-SPI

Izingqinamba ezijwayelekile zifaka izintambo ezingalungile, ukushesha kwe-Clock Mismatches, nenkohliso yedatha. Ukusebenzisa i-logic analyzer kungagxila ekuboneni nasekuxazululeni izinkinga ezinjalo. Njalo bhekisa kuma-datasheets akhethiwe wakho Umkhiqizo we-PC SPI Interface Futhi amadivaysi akho e-SPI ukuze uthole ukuqondiswa okunemininingwane yokuxazulula izinkinga.

Ukuze uthole ukuboniswa okuphezulu kwe-LCD kanye nezinto ezihlobene ukuze uthuthukise amaphrojekthi akho, cabanga ngokuhlola iminikelo kuyo I-Dalian Eastern Display Co, Ltd. Bahlinzeka ngezinketho ezahlukahlukene zezicelo ezahlukahlukene.

Lo mhlahlandlela unikeza ukuqonda kwesisekelo sokukhetha okungcono kakhulu Umkhiqizo we-PC SPI Interface. Khumbula ukubonana njalo nemibhalo esemthethweni kanye nokucaciswa komkhiqizo imininingwane enembile kakhulu futhi esesikhathini esesikhathini.
