Hlo Habr.
Π 5 txoj hauv kev los siv Raspberry Pi tau txiav txim siab. Cov ncauj lus tau nthuav tawm zoo heev, thiab hnub no kuv yuav saib ntau txoj hauv kev uas koj tuaj yeem siv lub microcomputer no rau koj kom zoo dua.
Duab los ntawm qhov chaw
Raws li nyob rau hauv tsab xov xwm dhau los, kuv yuav saib cov txheej txheem uas tsis tas yuav programming.
Rau cov neeg txaus siab, qhov txuas ntxiv yog nyob rau hauv kev txiav.
1. Lub koob yees duab saib xyuas
Tau qhov twg los:
Raspberry Pi tuaj yeem siv nrog yuav luag txhua lub koob yees duab kev ruaj ntseg.
Cov hauv qab no tuaj yeem ua haujlwm nrog Raspberry Pi:
- USB Webcams (xws li Logitech C910)
- IP lub koob yees duab (Axis, thiab lwm yam) nrog PoE injector (48V fais fab mov yog muab rau cov koob yees duab ntawm lub network cable, uas tso cai rau lawv txav mus rau sab nraud lub tsev)
- cov koob yees duab uas txuas ncaj qha mus rau lub connector ntawm RPi (raws li hauv daim duab saum toj no).
Muaj ntau ntau txoj kev xaiv rau customizing lub software ntawm no. Koj tuaj yeem siv lub pob , uas muaj qhov hloov tau yooj yim heev. Koj tuaj yeem sau ncaj qha los ntawm lub console siv ffmpeg, lossis thaum kawg koj tuaj yeem sau koj tus kheej siv Python thiab OpenCV. Koj tuaj yeem tshaj tawm cov kwj video, siv kev tshawb nrhiav, xa cov duab los ntawm email, thiab lwm yam.
Cov neeg txaus siab tuaj yeem saib cov kev qhia hauv qab no:
ib qho tseem ceeb: Nws twb tau hais nyob rau hauv qhov dhau los, tab sis nws yog qhov zoo dua los rov hais dua. Rau txhua qhov kev pabcuam siv zog (uas suav nrog kev ua yeeb yaj kiab) ntawm Raspberry Pi, yuav tsum muaj cov khoom lag luam zoo 2.5A fais fab tuag thiab cov khoom siv hluav taws xob tsis zoo ntawm CPU yog qhov xav tau (koj tuaj yeem tau txais nws pheej yig hauv Suav teb rau $ 1- 2 los ntawm kev tshawb nrhiav raspberry pi heatsink). Txwv tsis pub, lub cuab yeej yuav khov, cov ntaub ntawv luam tawm yuam kev yuav tshwm sim, thiab lwm yam.
2. Kev kaw suab
Nrog rau USB microphone, Raspberry Pi tuaj yeem siv los ua kab laum thiab cov cuab yeej kaw suab zoo. Ib zaug ntxiv, muaj ntau txoj kev xaiv rau customizing lub software - koj tuaj yeem sau cov ntaub ntawv hauv zos rau SD card, koj tuaj yeem tshaj tawm rau lwm lub PC, lossis tshaj tawm hauv lub network.
Qee qhov kev qhia rau kev tshuaj xyuas:
Los ntawm txoj kev, yog tias koj muaj lub microphone, Raspberry Pi tuaj yeem siv nrog thiab siv lub cuab yeej rau lub suab hais kom ua.
3. Prof. daim duab
Tsis txhob nkim p3 thiab p1. Hauv thawj kab lus peb tau tham txog cov koob yees duab saib video, tab sis Raspberry Pi kuj tseem tuaj yeem tswj cov koob yees duab tshaj lij los ntawm Canon, Nikon, Sony, thiab lwm yam. Lub koob yees duab tsuas yog xav tau txuas nrog Raspberry Pi ntawm USB.
Duab los ntawm qhov chaw
Cov Tsev Qiv Ntawv ΠΈ muaj ob qho tib si muaj peev xwm ua haujlwm los ntawm kab hais kom ua thiab cuam tshuam rau Python thiab C ++, uas tso cai rau koj siv Raspberry Pi los tswj "DSLR", piv txwv li, rau kev yees duab time-lapse. Nws loj txaus thiab npog yuav luag txhua tus qauv, los ntawm cov niaj hnub mus rau cov laus los ntawm 10 xyoo dhau los. Libgphoto2 muaj txaus , thiab tuaj yeem tswj tsis tau lub shutter nkaus xwb, tab sis kuj hloov chaw, upload cov ntaub ntawv, thiab lwm yam.
Cov lus qhia rau kev tshuaj xyuas:
Los ntawm txoj kev, koj tuaj yeem sau cov duab rau hauv lub koob yees duab daim npav nco lossis ncaj qha mus rau Raspberry Pi, uas tso cai rau, piv txwv li, cia li xa lawv mus rau "huab". Kuj tseem muaj cov tsev qiv ntawv rau kev tswj tsis yog SLR nkaus xwb, tab sis kuj muaj hnub qub (piv txwv li ZWO ASI) koob yees duab, suav nrog txawm tias .
4. Chaw nres tsheb huab cua
Raspberry Pi "ua tau" tsis yog tsuas yog khiav Linux cov kev pab cuam, tab sis kuj tau tsim cov khoom siv ncaj ncees - serial, I2C, SPI, GPIO. Qhov no ua rau lub cuab yeej yuav luag zoo tagnrho rau kev sau thiab xa cov ntaub ntawv los ntawm ntau lub sensors - los ntawm qhov ntsuas kub thiab av noo mus rau dosimeter raws li Geiger txee.
Duab los ntawm qhov chaw
Los ntawm txoj kev, yog tias koj tau tub nkeeg tiag tiag, koj tuaj yeem nqa cov ntaub ntawv tsis yog los ntawm koj cov sensors nkaus xwb tab sis kuj los ntawm lub vev xaib, qhov kev xaiv no kuj muaj txoj cai muaj nyob. Txawm li cas los xij, lub rooj tsavxwm nrog sensors rau Raspberry Pi tsis nyuaj .
Tutorials rau kev kawm:
5. Game console
Siv qhov project Koj tuaj yeem tig Raspberry Pi rau hauv "retro" emulator ntawm ntau yam kev ua si consoles, los ntawm Atari mus rau Gameboy lossis ZX Spectrum. Koj tuaj yeem yuav ntau rooj plaub, joysticks, thiab lwm yam.
Kuv nyob deb ntawm kev ua si, yog li kuv tsis tuaj yeem hais meej ntxiv, leej twg tuaj yeem sim nws ntawm lawv tus kheej. Ob peb qhov kev qhia kom kawm:
xaus
Kuv vam tias muaj cov tswv yim tshiab txaus rau tej yam uas yuav ua rau hnub so no. Yog tias qhov kev ntaus nqi rau tsab xov xwm yog qhov zoo, qhov thib peb yuav raug tshaj tawm.
Raws li ib txwm muaj, kev zoo siab sim txhua tus.
