phendula umbuzo othi yini okusajingijolo ukukhuluma ngobuchwepheshe obusabalele kakhulu emhlabeni wokuzijabulisa okulalelwayo nokubonwayo. Ingenye yamabhodi e-microcomputer aziwa kakhulu. Ubukhulu bayo obuncane kanye nentengo kuvumela imisebenzi eyinhloko yekhompyutha ukuthi ilethwe kuzo zonke izinhlobo zezethameli. Kukhona ngisho nokubambisana okuqinile nezikhungo zemfundo zokuthengwa kwenqwaba yalezi zisetshenziswa. Ngokulandelayo, i-Raspberry Pi ikhona ezikhungweni zemultimedia ezihlukene kanye nama-consoles wegeyimu yevidiyo, asephenduke ama-microcomputer anemisebenzi yokuzijabulisa kanye nokuzijabulisa kwe-multimedia.
Kulokhu okuthunyelwe sizokwazi izici eziyinhloko nemisebenzi ye-Raspberry, kanye amaqhinga okucushwa kwakho. Ungathola kanjani okuningi ebhodini eliletha ubuchwepheshe bekhompyutha ekhaya lakho noma ehhovisi, ngamanani athengekayo kakhulu.
Amandla okusajingijolo
El i-raspberry microcomputer efunwa kakhulu ezikhungweni zemfundo, iza nesistimu yokusebenza ye-Linux futhi isiza ukufunda izilimi zokuhlela ze-Scratch ne-Python. Ikuvumela ukuthi wenze yonke imisebenzi eyisisekelo yekhompuyutha yedeskithophu, ngokunethezeka kokuxhuma ku-smart TV noma ugade kalula ngokusekelwa kwamagundane ajwayelekile namakhibhodi. Ungaphequlula i-inthanethi, udlale amavidiyo ngokulungiswa okuphezulu, usebenze ngamafayela ehhovisi futhi udlale imidlalo yamavidiyo yakudala evela kuma-emulators.
Izingane, intsha kanye nabantu abadala bangasebenzisa ezinye zezinhlobonhlobo zokusetshenziswa namandla okusajingijolo. Kusukela imodeli yayo yasekuqaleni ngo-2012, ibilokhu ithola izibuyekezo kanye nokwengezwa kwamandla engeziwe. Imodeli yayo yakamuva kakhulu i-Raspberry Pi 3 B+. Kuyini futhi yiziphi izici le Raspberry entsha enazo:
- I-GPIO yamaphini angu-40 esebenza ku-3.3V.
- Izimbobo ze-USB.
- Uxhumano lwenethiwekhi ye-Ethernet.
- 3.5 millimeter ujeke.
- microSD port, I2C, SPI, UART.
- isixhumi se-micro USB.
Ukusetshenziswa okuningi kwe-raspberry
Uma sicabanga ngokusetshenziswa okuhlukene okunganikezwa ikhompuyutha encane, sihlanganise imibono ethakazelisayo ukusizakala amandla ayo. Kusukela kuma-consoles e-retro ukuze udlale imidlalo yevidiyo, ukuya kukhompuyutha encane ukuze udlale okuqukethwe okulalelwayo nokubonwayo, indawo ye-LED noma izinhlelo zokuphepha kanye nezinhlelo ezizenzakalelayo zasekhaya.
Ungakwazi setha okusajingijolo ukwenza ngokuzenzakalelayo izici ezihlukene zekhaya lakho elihlakaniphile, ukulawula izinga lokushisa, ukukhanyisa noma ngisho nesistimu yezimpumputhe ezizenzakalelayo. Uma uthanda imidlalo yevidiyo yakudala, ama-consoles amaningi e-retro ane-Raspberry Pi enhliziyweni yawo, kodwa ungakwazi nokusetha eyakho ngobuhlakani obuncane. Amakhompiyutha amancane axhumeka kalula kumonitha noma isikrini, futhi ahambisana namakhibhodi ajwayelekile namagundane.
Emsuka wayo, umsebenzi weRaspberry wawufundisa kuphela. Yingakho yakhelwe ngendlela yokuthi ukufunda ukuhlela kulula kakhulu. Namuhla, abasebenzisi bangenza imisebenzi eminingi kusukela ngokuphequlula iwebhu nokusebenzisa izinhlelo zokusebenza zehhovisi, kuze kufike ekwakhiweni kwesikhungo esincane semidiya. Amamodeli amanje afaka izimbobo ze-HDMI ukuze uxhumeke ngqo ku-TV noma ugade futhi udlale okuqukethwe lapho.
Ukulinganiselwa
Ngesikhathi intengo namandla ayo kukhanga kakhulu, kubalulekile ukuqaphela ukulinganiselwa okungase kulethwe yilezi zisetshenziswa. Ijubane layo linciphile uma liqhathaniswa nekhompyutha evamile, futhi ngezinye izikhathi ukusefa inetha noma ukufunda amanye amafayela kungase kuhambe kancane.
Ingasetshenziswa njengeseva, kodwa kuphela kumakhasi ewebhu ezindaweni zokuhlola nokuhlola. Ekusebenzeni okuvamile kweseva, kuyadingeka ukuba nesistimu yokubamba echwepheshile.
Yiziphi izinhlelo zokusebenza ezisebenza ku-Raspberry?
Kuwebhusayithi esemthethweni ye-Raspberry Foundation sithola lonke ulwazi mayelana namamodeli nezici zobuchwepheshe zemodeli ngayinye. Kodwa singabona futhi ukuthi yiziphi izinhlelo zokusebenza ezihambisana ne-microcomputer ngayinye. Isincomo esijwayelekile yi-Raspberry Pi OS, isistimu yokusebenza yokuphathelene, kodwa futhi kukhona ukusekelwa kwe-Linux kanye Windows 10 IoT (inguqulo ethile yalolu hlobo lwebhodi).
I-microcomputer yonjiniyela
En los Umsuka we-Raspberry Pi Foundation, kwakuyisifiso sokuthi abancane eGreat Britain, bafunde isayensi yekhompyutha. Ukwanda kwayo emakethe kuholele abantu abahlukene ukuthi badlale futhi bazame ezinye izindlela zekhompiyutha, amadivaysi ohlelo, imisebenzi kanye nezakhi zokufeza imisebenzi yazo zonke izinhlobo. Kusukela ekulawuleni ikhaya elihlakaniphile ukuya kukhompuyutha yasekhaya encane ukuze usebenzise i-inthanethi noma udlale okuqukethwe kwe-multimedia.
Abantu abaningi abaqala ukwenza izinhlelo bathatha izinyathelo zabo zokuqala ngalolu hlobo lwedivayisi. Ngokulandelayo, kwenziwa inqubekelaphambili ekuhleleni amakhompuyutha endabuko, kodwa kusizakala ngolwazi kanye nokulula ukuqala ukuhlela ngeRaspberry. Intengo yayo ethengekayo kanye nezinhlobonhlobo zezenzo ezitholakalayo zenza le khompyutha encane ibe ithuluzi elinconywa kakhulu ukwenza a inqubo yokuqeqeshwa kolwazi. Okwezikole kanye nabantu abazimisele ngokufunda nokuthuthukisa amakhono abo. Ngamanani afinyelelekayo namandla ahlukahlukene ukuhlangabezana nezinjongo ezihlukahlukene kakhulu ngokwezidingo zomsebenzisi ngamunye.
