Izimiso kanye Nokusetshenziswa Kokulawula Isiqandisi Nge-Single-Chip Microcomputers

Empilweni yanamuhla, iziqandisi zilawula izinga lokushisa ngamakhompiyutha e-single-chip. Uma intengo iphakeme, kungcono ukuzinza kwezinga lokushisa. Njengohlobo lwe-microcontroller, ama-microcomputer e-single-chip ahlukaniswe abe izinhlobo ezahlukene.

Ezivamile zingafinyelela ukulawula okunembile kweziqandisi futhi zithuthukise ukusebenza nokusebenza kahle kweziqandisi. Ngakho-ke, isiqandisi seziqandisi asifinyelelwa ngokuphelele ngemisebenzi yemishini.

I. Uyini ngempela umgomo wokulawulwa kwesiqandisi ngamakhompiyutha e-single-chip?

Ngokwemibandela yobungcweti, isho ukuzuza ukuqapha nokulawula izinga lokushisa, umswakama, isistimu yesiqandisi, njll. yesiqandisi ngokuxhuma izinzwa ezihlukahlukene nama-actuator.

Izinyathelo eziqondile zimi kanje:

① Abasebenzisi basetha izinga lokushisa, elisebenza njengenani eliyireferensi ukuze isiqandisi silungise izinga lokushisa.

② Inzwa yezinga lokushisa iqapha izinga lokushisa ngaphakathi kwesiqandisi ngesikhathi sangempela.

③ Bala ushintsho phakathi kwezinga lokushisa ngaphakathi kwesiqandisi kanye nenani elimisiwe. Uma izinga lokushisa ngaphakathi kwesiqandisi liphakeme kunezinga lokushisa elibekiwe, i-microcomputer ye-single-chip ilawula uhlelo lwesiqandisi ukuze luqale isiqandisi ukwehlisa izinga lokushisa ngaphakathi kwesiqandisi. Uma izinga lokushisa liphansi kunenani elibekiwe, i-microcomputer ye-single-chip yesiqandisi izolawula uhlelo lwesiqandisi ukuyeka ukusebenza ukuze kugcinwe izinga lokushisa ngaphakathi kwesiqandisi lizinzile.

Okungenhla kuyisimiso sesiqandisi. Ngokuqondene ne-defrosting neminye imisebenzi, nazo zilawulwa ngokuvumelana nezinga lokushisa, njengokwandisa izinga lokushisa, ukulawula isivinini sokujikeleza kwefeni, njll.

II. Ukulawulwa kwesiqandisi nge-single-chip microcomputer kungafezwa ngokusebenzisa amakhodi okubonisa (ngereferensi yokubonisa kuphela).

Incazelo: Lo msebenzi usebenzisa ijeneretha yenombolo engahleliwe ukuze ilingise ukufundwa kwenzwa yezinga lokushisa. Kuzinhlelo zokusebenza ezisebenzayo, inzwa yokushisa yangempela ingaxhunywa kuphinikhodi ye-single-chip microcomputer, futhi izinga lokushisa langempela lingatholwa ngokufunda inani lokukhipha inzwa.

Incazelo: Lo msebenzi ulawula ukuqala nokumiswa kwesistimu yesiqandisi ngokusho kwezinga lokushisa lamanje kanye nezinga lokushisa eliqondiwe. Uma izinga lokushisa lamanje liphakeme kunezinga lokushisa eliqondiwe, uhlelo lwesiqandisi luzoqalwa. Uma izinga lokushisa lamanje liphansi noma lilingana nezinga lokushisa elihlosiwe, uhlelo lwesiqandisi luzomiswa.

Incazelo: Lo msebenzi usetshenziselwa ukubonisa izinga lokushisa lamanje kanye nesimo sesistimu yesiqandisi. Kuzinhlelo zokusebenza ezingokoqobo, isibonisi sekristalu ewuketshezi noma ezinye izisetshenziswa zokubonisa zingasetshenziswa ukubonisa lolu lwazi ukuze abasebenzisi bazi isimo sokusebenza sesiqandisi noma kunini.

III. Isifinyezo

Ngokusetshenziswa kwamakhodi angenhla, i-microcomputer ye-single-chip ingakwazi ukulawula ngokuphumelelayo izinga lokushisa nesistimu yesiqandisi yesiqandisi futhi ithuthukise ukusebenza nokusebenza kahle kwesiqandisi. Yiqiniso, lokhu kuyisibonelo nje esilula, esingavumela ngokucacile amakhasimende ukuthi azi okuqukethwe kwezobuchwepheshe kwesiqandisi. Iphinde izuzwe ngama-chips, izilawuli kanye nochungechunge lobuchwepheshe beziqandisi. Iziqandisi zokudla eziningi ezithengiswayo neziqandisi zezokwelapha zilawulwa amakhompiyutha angama-single-chip. Ungayicabanga njengokuthi ilawulwa ikhompuyutha encane, futhi izoba nohlu olubanzi lwezinhlelo zokusebenza empilweni yangempela. Ukuphakama kokuqukethwe kwezobuchwepheshe, kuba ngcono umuzwa womsebenzisi.
