Koj tau pom nws hauv xov xwm, koj tus phooj ywg muaj ib qho, thiab koj paub tseeb tias nws tsis yog khoom noj. Koj tau hais tias, "Nws yog $ 35 lub khoos phis tawj uas haum rau hauv koj lub hnab ris," tab sis koj tsis tau npaj siab ntseeg qhov ntawd. Yog li, Raspberry Pi yog dab tsi? Raws li qhov tshwm sim tsis tau zoo li, Pi yog ib qho pheej yig mini-computer, tab sis muaj ntau ntxiv rau zaj dab neeg.
Peb yuav piav qhia seb lub rooj tsav xwm ntsuab no yog dab tsi, yog vim li cas koj thiaj xav tau ib qho, thiab nws nyiam li cas hauv qab no.
A Visual Introduction
Cia peb pib nrog daim duab ntawm qhov tshiab tshaj plaws, Raspberry Pi 4.
Thaum tib neeg qhia koj Raspberry Pi yog $ 35 lub khoos phis tawj, feem ntau lawv tsis nco qab qhia tias koj tsuas tau txais lub rooj tsavxwm rau tus nqi nqe lus ntawd xwb. Tsis muaj qhov screen, tsis muaj drives, tsis muaj peripherals, thiab tsis muaj casing. Txoj hlua khi ntawd zoo nkauj heev, tab sis nws tuaj yeem ua rau tsis meej pem.
Yog li cas?
Lub Raspberry Pi yog micro-koob computer pib tsim los rau kev kawm. Nws muaj tag nrho cov khoom uas koj xav pom ntawm lub desktop PC-tus processor, RAM, HDMI chaw nres nkoj, suab tso zis, thiab USB chaw nres nkoj ntxiv rau cov khoom siv xws li keyboard thiab nas.
Nrog rau cov khoom pov thawj pom tau yog ib qho ntawm qhov tseem ceeb ntawm Pi-the GPIO (General Purpose Input Output) header. Qhov no yog qhov thaiv cov pins uas cia koj txuas koj lub Raspberry Pi rau lub ntiaj teb tiag tiag, txuas cov khoom xws li keyboards, LEDs, thiab sensors (thiab ntau dua), uas koj tswj nrog qee qhov yooj yim code.
Nws kuj tseem ua haujlwm puv npo ua haujlwm raws li Debian Linux, hu ua Raspbian. Yog tias qhov ntawd tsis txhais tau ntau rau koj, xav txog tias Windows, Linux, thiab Apple OS X yog txhua qhov kev khiav haujlwm.
Kev sib piv PC xaus muaj (Tej zaum)
Qhov kev sib piv rau ib lub PC desktop ib txwm zoo nkauj heev xaus rau ntawd. Lub Raspberry Pi yog lub hwj chim qis (5V) micro-computer. Nws tau siv los ntawm micro-USB fais fab mov zoo ib yam li lub xov tooj smartphone charger thiab muab kev suav lub zog zoo ib yam li lub xov tooj ntawm tes.
Qhov kev teeb tsa hluav taws xob qis no ib txwm ua tau zoo rau kev ua haujlwm thiab cov haujlwm hluav taws xob. Txawm li cas los xij, nws tuaj yeem xav tias qeeb me ntsis raws li lub PC niaj hnub.
Txawm li cas los xij, qhov tseeb Raspberry Pi 4 muaj kev ua tau zoo dua qub dua li yav dhau los ntawm Raspberry Pi, thiab nws tau raug muag raws li lub peev xwm hloov pauv. Qhov ntawd yuav tsis muaj tseeb ntawm tag nrho cov versions ntawm Pi. Tej zaum koj yuav xav tau yam tsawg kawg yog 4 GB ntawm RAM coj kom zoo dua nws ua lub desktop PC.
Hais tias, peb tsis tau tham txog lub chaw ua haujlwm puv npo. Lub Pi yog kwv yees sib npaug rau nruab nrab Chromebook. Yog li, yog tias koj tuaj yeem tau txais los ntawm Chromebook ua koj lub PC tseem ceeb, koj tuaj yeem siv Pi ua koj lub desktop thawj.
Yuav ua li cas?
Pi tsis tau tsim los ua lub chaw ua haujlwm PC, thiab nws tsis khiav Windows. Nws tsis tuaj rau hauv rooj plaub, thiab tej zaum koj yuav tsis pom nws hloov PCs hauv chaw ua haujlwm sai sai.
Pi yog npaj rau kev ua haujlwm, hluav taws xob, thiab DIY tej yaam num. Nws yog thawj zaug tsim los daws qhov txo qis ntawm cov tub ntxhais kawm uas muaj kev txawj ntse thiab kev txaus siab hauv computer science.
Txawm li cas los xij, raws li nws cov koob meej thiab kev pom tau nce ntxiv, cov neeg ntawm txhua lub hnub nyoog thiab keeb kwm tau tsim ib lub zej zog loj ntawm cov neeg nyiam uas xav kawm.
Kuv Yuav Ua Li Cas?
Yog tias koj xav siv koj tus Pi los txhim kho koj cov kev txawj coding, koj tuaj yeem siv ib hom lus txhawb nqa (xws li Python) los tsim cov kev pab cuam. Qhov ntawd tuaj yeem yog txhua yam los ntawm kev luam ntawv "nyob zoo ntiaj teb" ntawm qhov screen, mus txog ntau txoj haujlwm nyuaj, xws li kev ua si.
Yog tias koj txaus siab rau kho vajtse thiab khoom siv hluav taws xob, koj tuaj yeem txhim kho qhov kev pab cuam no los ntawm kev siv GPIO ntxiv cov keyboards, sensors, thiab cov khoom siv lub cev tiag tiag los tham nrog cov cai no.
Koj tuaj yeem ntxiv cov khoom tawm ntawm lub cev xws li LEDs, hais lus, thiab lub cev muaj zog ua haujlwm thaum koj tus lej qhia rau lawv. Muab cov no tso ua ke, thiab koj tuaj yeem ua qee yam zoo li tus neeg hlau tsis muaj sijhawm.
Tsiv deb ntawm kev ua haujlwm, muaj ntau tus neeg siv uas yuav Pi ua lwm txoj hauv kev rau lwm yam khoom siv. Siv Pi raws li KODI media center yog ib qhov project nrov, piv txwv li, noj qhov chaw ntawm cov khoom kim tshaj tawm ntawm lub txee.
Tsis muaj kev paub dhau los
Tej zaum koj xav tias koj xav tau qee qhov kev ua haujlwm ua ntej lossis kev paub siv hluav taws xob kom tau txais nrog lub rooj tsav xwm ntsuab me me no. Qhov ntawd yog qhov kev pom tsis zoo uas peb xav tias tau tso tawm ntau txhiab tus neeg siv tau.
Koj tsis tas yuav muaj keeb kwm ntau nrog khoos phis tawj siv Raspberry Pi. Yog tias koj siv PC lossis laptop, koj yuav zoo. Yog lawm, koj yuav muaj qee yam los kawm, tab sis qhov ntawd yog tag nrho cov ntsiab lus.
Cov peev txheej ntau thiab kev txhawb nqa hauv zej zog yuav luag lav tias koj yuav tsis poob. Yog tias koj tuaj yeem siv Google, koj tuaj yeem siv Raspberry Pi.
Vim li cas thiaj nrov?
Lub Raspberry Pi qhov kev muaj koob meej thiab kev vam meej tsis tu ncua yog vim nws cov nqi siv tau thiab cov zej zog zoo kawg.
Nyob $35, nws tau nyiam ntau tus neeg siv los ntawm cov menyuam kawm ntawv mus rau cov kws tshaj lij programmers. Tseem, tus nqi tsis yog qhov tseem ceeb ntawm no.
Lwm yam khoom zoo sib xws uas tau sim nyiaj hauv lub khw no tsis tau los ze, thiab vim tias cov zej zog nyob ib puag ncig Raspberry Pi yog qhov ua rau nws tshwj xeeb.
Yog tias koj tau daig, xav tau kev qhia, lossis tab tom nrhiav kev tshoov siab, hauv is taws nem nrog cov phooj ywg cov neeg siv muab kev pab hauv kev sib tham, blogs, kev sib tham, thiab ntau dua.
Tseem muaj sijhawm los ntsib tus neeg ntawm Raspberry Jams, qhov twg cov neeg nyiam nyiam tuaj koom ua ke los qhia cov haujlwm, daws teeb meem, thiab kev sib raug zoo.
Kuv Yuav Tau Ib Qhov twg?
Ntawm no yog qee lub khw muag khoom tseem ceeb yuav ib qho:
UK
Nrog lub rooj tsavxwm tau tsim nyob rau hauv UK, muaj ntau lub khw Pi hauv UK. Key Pi superstores zoo li Pi Hut, Pimoroni, ModMyPi, PiSupply, thiab RS Electronics yuav muaj lawv hauv Tshuag thiab npaj xa tawm.
USA
Hauv Asmeskas, cov khw muag khoom hluav taws xob, zoo li Micro Center, yuav muaj cov khoom lag luam zoo ntawm Pi, ib yam li Newark Element14 thiab cov khw muag khoom xws li Adafruit.
Lwm lub tebchaws muaj Pi khw ntawm no thiab nyob ntawd, tab sis kev muaj koob meej tsis muaj zog li UK thiab Asmeskas. Kev saib sai ntawm koj lub teb chaws lub tshuab tshawb nrhiav yuav tsum ua kom pom cov txiaj ntsig hauv zos.
