Iindlela ezi-5 eziluncedo zokusebenzisa iRaspberry Pi. Icandelo lesibini

Molo, Habr.

В Inxalenye yokuqala Iindlela ezi-5 zokusebenzisa i-Raspberry Pi zaqwalaselwa. Isihloko siye sanomdla kakhulu, kwaye namhlanje ndiza kujonga ezinye iinketho ezininzi malunga nendlela onokuyisebenzisa ngayo le microcomputer.

Njengakwicandelo elidlulileyo, ndiza kujonga ezo ndlela zingadingi inkqubo.
Kwabo banomdla, ukuqhubeka kuphantsi kokusikwa.

1. Ikhamera yokubeka iliso

I-Raspberry Pi ingasetyenziswa phantse zonke iikhamera zokhuseleko.
Oku kulandelayo kunokusebenza kunye neRaspberry Pi:

• Iikhamera zewebhu ze-USB (umzekelo, iLogitech C910)
• Iikhamera ze-IP (i-Axis, njl.) ezine-injector ye-PoE (amandla e-48V anikezelwa kwiikhamera ezinjalo ngentambo yenethiwekhi, evumela ukuba bahanjiswe ngaphandle kwesakhiwo)
• iikhamera ezidibanisa ngokuthe ngqo kwikhonkco kwi-RPi (njengasesithombeni esingentla).

Kukho izinto ezininzi onokukhetha kuzo ukwenza isoftware ngokwezifiso apha. Ungasebenzisa iphakheji Ukuhamba, enesethingi ebhetyebhetye. Ungabhala ngokuthe ngqo kwi-console usebenzisa i-ffmpeg, okanye ekugqibeleni ungabhala eyakho isibambi usebenzisa iPython kunye ne-OpenCV. Ungasasaza umjelo wevidiyo, sebenzisa ukubonwa kwentshukumo, uthumele iifoto nge-imeyile, njl.

Abo banomdla banokubukela ezi tutorials zilandelayo:

• medium.com/@gonzalovazquez/raspberry-pi-and-motioneye-setting-up-your-own-video-surveilance-95444e0faad

ebalulekileyo: Kwakusele kukhankanyiwe kwinxalenye yangaphambili, kodwa kungcono ukuyiphinda. Kuyo nayiphi na imisebenzi enobutyebi (ebandakanya ukusetyenzwa kwevidiyo) kwiRaspberry Pi, umbane okumgangatho ophezulu we-2.5A uyafuneka kwaye i-heatsink esebenzayo kwi-CPU iyanqweneleka (ungayifumana ngexabiso eliphantsi e-China nge- $ 1- 2 ngokukhangela iraspberry pi heatsink). Kungenjalo, isixhobo singaba ngumkhenkce, iimpazamo zokukopisha iifayile zinokuvela, njl.

2. Ukurekhoda komsindo

Ngomakrofoni we-USB, iRaspberry Pi inokusetyenziswa njenge-bug kunye nesixhobo sokurekhoda somsindo esidibeneyo. Kwakhona, zininzi iinketho zokwenza isoftware ngokwezifiso - ungabhala iifayile kwindawo yakho kwikhadi le-SD, ungasasaza kwenye iPC, okanye usasaze ngenethiwekhi.

Izifundo ezimbalwa zophononongo:

• blog.mutsuda.com/raspberry-pi-into-an-audio-spying-device-7a56e7a9090e
• www.heidislab.com/tutorials/audio-streaming-with-raspberry-pi-zero-w-and-adafruits-i2s-mic

Ngendlela, ukuba une-microphone, i-Raspberry Pi inokusetyenziswa nayo Amazon Alexa kwaye usebenzise isixhobo kwimiyalelo yelizwi.

3. UProf. ifoto

Musa ukubhidanisa i-p3 kunye ne-p1. Kumhlathi wokuqala sasithetha ngeekhamera zokucupha ividiyo, kodwa i-Raspberry Pi inokulawula iikhamera zobuchwephesha ezivela kwiCanon, i-Nikon, i-Sony, njl.

Ifoto evela kwindawo www.movingelectrons.net/blog/2017/08/09/Camera-Time-lapse-Controller-with-Python-and-Raspberry-Pi.html

Amathala eencwadi ifoto2 и libgphoto2 zibe zombini amandla okusebenza ukusuka kumgca womyalelo kunye ne-interfaces ye-Python kunye ne-C ++, evumela ukuba usebenzise i-Raspberry Pi ukulawula "i-DSLR", umzekelo, ukufota ixesha elide. Uluhlu lweekhamera ezixhaswayo Inkulu ngokwaneleyo kwaye igubungela phantse zonke iimodeli, ukusuka kule mihla ukuya kwakudala ukusuka kwiminyaka eyi-10 eyadlulayo. I-Libgphoto2 inokwaneleyo phambili API, kwaye ayikwazi ukulawula kuphela i-shutter, kodwa iphinde iguqule izicwangciso, iifayile zokulayisha, njl.

Izifundiso zophononongo:

• pimylifeup.com/raspberry-pi-dslr-camera-control
• medium.com/@cgulabrani/controlling-your-dslr-through-raspberry-pi-ad4896f5e225

Ngendlela, ungabhala imifanekiso okanye kwimemori khadi yekhamera okanye ngokuthe ngqo kwi-Raspberry Pi, evumela, umzekelo, ukuba uzilayishe ngokuzenzekelayo "kwilifu". Kukwakho amathala eencwadi okulawula kungekuphela nje i-SLR, kodwa kunye neekhamera zeenkwenkwezi (umzekelo ZWO ASI), kubandakanywa nokuba i-autoguiding.

4. Isikhululo semozulu

I-Raspberry Pi "ingakwazi" ukuqhuba iinkqubo ze-Linux kuphela, kodwa ineeperipherals eziphuhliswe ngokufanelekileyo-i-serial, i-I2C, i-SPI, i-GPIO. Oku kwenza ukuba isixhobo siphantse silungele ukuqokelela kunye nokuthumela idatha evela kwi-sensors ezahlukeneyo - ukusuka kwiqondo lokushisa kunye ne-humidity sensors ukuya kwi-dosimeter esekelwe kwikhawunta ye-Geiger.

Ngendlela, ukuba uyonqena ngokwenene, unokuthatha idatha kungekhona kuphela kwi-sensors zakho kodwa nakwiwebhu, olu khetho lunelungelo lokuba khona. Nangona kunjalo, ibhodi enezinzwa zeRaspberry Pi ayinzima thenga ngokwahlukeneyo.

5. Ikhonsoli yomdlalo

Ukusebenzisa iprojekthi RetroPie unokuguqula iRaspberry Pi ibe yi-emulator "ye-retro" yee-consoles ezahlukeneyo zomdlalo, ukusuka kwi-Atari ukuya kwi-Gameboy okanye i-ZX Spectrum. Ungaphinda uthenge iimeko ezahlukeneyo, i-joystick, njl.

Ndikude nemidlalo, ngoko andinakutsho ngokweenkcukacha ngakumbi, nabani na unokuzama eyedwa. Izifundo ezimbalwa zokufunda:

• www.pcworld.com/article/3190347/how-to-build-a-raspberry-pi-retrogaming-emulation-console.html
• thewirecutter.com/reviews/raspberry-pi-game-console

isiphelo

Ndiyathemba ukuba kukho imibono emitsha eyaneleyo yokwenza izinto kule mpelaveki. Ukuba iireyithingi zenqaku zilungile, inxalenye yesithathu iya kuthunyelwa.

Njengesiqhelo, imifuniselo eyonwabileyo wonke umntu.
