Izindlela ezi-5 eziwusizo zokusebenzisa i-Raspberry Pi. Ingxenye yesibili

Sawubona, Habr.

В ingxenye yokuqala Kucatshangelwe izindlela ezi-5 zokusebenzisa i-Raspberry Pi. Isihloko siphenduke saba mnandi, futhi namuhla ngizobheka ezinye izinketho eziningi zokuthi ungasebenzisa kanjani le microcomputer ukuze uzuze.

Isithombe esisuka kusayithi funda.adafruit.com

Njengasengxenyeni edlule, ngizobheka lezo zindlela ezingadingi ukuhlelwa.
Kulabo abanentshisekelo, ukuqhubeka kungaphansi kokunqunywa.

1. Ikhamera yokugada

I-Raspberry Pi ingasetshenziswa cishe nawo wonke amakhamera okuphepha.
Okulandelayo kungasebenza ne-Raspberry Pi:

• Amakhamera ewebhu e-USB (isb i-Logitech C910)
• Amakhamera we-IP (i-Axis, njll.) ane-PoE injector (amandla angu-48V anikezwa kumakhamera anjalo ngentambo yenethiwekhi, ewavumela ukuthi ahanjiswe ngaphandle kwesakhiwo)
• amakhamera axhuma ngqo kusixhumi ku-RPi (njengasesithombeni esingenhla).

Kunezinketho eziningi zokwenza isoftware ngokwezifiso lapha. Ungasebenzisa iphakheji Motion, enezilungiselelo ezivumelana nezimo. Ungabhala ngokuqondile usuka kukhonsoli usebenzisa i-ffmpeg, noma ekugcineni ungabhala isibambi sakho usebenzisa iPython ne-OpenCV. Ungasakaza ukusakaza kwevidiyo, usebenzise ukuthola ukunyakaza, uthumele izithombe nge-imeyili, njll.

Abanentshisekelo bangabuka izifundo ezilandelayo:

• www.bouvet.no/bouvet-deler/utbrudd/building-a-motion-activated-security-camera-with-the-raspberry-pi-zero
• hackernoon.com/spy-your-pet-with-a-raspberry-pi-camera-server-e71bb74f79ea
• medium.com/@gonzalovazquez/raspberry-pi-and-motioneye-setting-up-your-own-video-surveilance-95444e0faad

ezibalulekile: Bekushiwo kakade engxenyeni edlule, kodwa kungcono ukuyiphinda. Kunoma imiphi imisebenzi edinga izinsiza (okuhlanganisa ukucutshungulwa kwevidiyo) ku-Raspberry Pi, kudingeka ugesi wekhwalithi ephezulu obizwa nge-2.5A futhi i-heatsink engenzi lutho ku-CPU iyadingeka (ungayithola ishibhile e-China ngo-$1- 2 ngokufuna okusajingijolo pi heatsink). Uma kungenjalo, idivayisi ingase imiswe, amaphutha okukopisha ifayela angase avele, njll.

2. Ukurekhoda komsindo

Ngombhobho we-USB, i-Raspberry Pi ingasetshenziswa njengesiphazamisi kanye nedivayisi yokuqopha umsindo ehlangene kahle. Futhi, kunezinketho eziningi zokwenza isofthiwe ngendlela oyifisayo - ungabhala amafayela endaweni ekhadini le-SD, ungasakaza kwenye i-PC, noma usakaze ngenethiwekhi.

Izifundo ezimbalwa ezizobuyekezwa:

• 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, uma une-microphone, i-Raspberry Pi ingasetshenziswa nayo Amazon Alexa futhi usebenzise idivaysi ukuze uthole imiyalo yezwi.

3. UProf. isithombe

Ungaphambanisi u-p3 no-p1. Esigabeni sokuqala besikhuluma ngamakhamera okuqapha ividiyo, kodwa i-Raspberry Pi ingakwazi futhi ukulawula amakhamera angochwepheshe asuka kuCanon, Nikon, Sony, njll. Ikhamera idinga nje ukuxhumeka ku-Raspberry Pi nge-USB.

Isithombe esisuka kusayithi www.movingelectrons.net/blog/2017/08/09/Camera-Time-lapse-Controller-with-Python-and-Raspberry-Pi.html

Imitapo yolwazi gphoto2 и libgphoto2 ube nakho kokubili amandla okusebenza kusukela kulayini womyalo kanye nezindawo zokusebenzelana zePython ne-C++, okukuvumela ukuthi usebenzise i-Raspberry Pi ukuze ulawule i-“DSLR”, isibonelo, ukuthwebula izithombe ezidlula isikhathi. Uhlu lwamakhamera asekelwayo Inkulu ngokwanele futhi ihlanganisa cishe wonke amamodeli, kusukela kwanamuhla kuya kwakudala kusukela eminyakeni engu-10 edlule. I-Libgphoto2 inokwanele i-API ethuthukisiwe, futhi ayikwazi ukulawula i-shutter kuphela, kodwa futhi iguqule izilungiselelo, layisha amafayela, njll.

Okokufundisa okumele kubuyekezwe:

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

Ngendlela, ungabhala izithombe kumemori khadi yekhamera noma ngqo ku-Raspberry Pi, okuvumela, isibonelo, ukuzilayisha ngokuzenzakalelayo "efwini". Kukhona futhi imitapo yolwazi yokulawula hhayi kuphela i-SLR, kodwa futhi namakhamera ezinkanyezi (isibonelo i-ZWO ASI), okuhlanganisa ngisho i-autoguiding.

4. Isiteshi sezulu

I-Raspberry Pi "ayikwazi" ukusebenzisa izinhlelo ze-Linux kuphela, kodwa futhi inezindawo zokujikeleza ezithuthukisiwe - i-serial, i-I2C, i-SPI, i-GPIO. Lokhu kwenza idivayisi icishe ilungele ukuqoqa nokuthumela idatha kusuka kuzinzwa ezihlukahlukene - kusukela kuzinzwa zezinga lokushisa nokuswakama kuya kudosimitha esekelwe kwikhawunta ye-Geiger.

Ngendlela, uma uthola ubuvila ngempela, ungathatha idatha hhayi kuphela kuzinzwa zakho kodwa futhi kusukela kuwebhu, le nketho nayo inelungelo lokuba khona. Kodwa-ke, ibhodi elinezinzwa ze-Raspberry Pi alinzima thenga ngokwehlukana.

5. Ikhonsoli yegeyimu

Ukusebenzisa iphrojekthi I-RetroPie ungakwazi ukushintsha i-Raspberry Pi ibe i-emulator “ye-retro” yamakhonsoli egeyimu ahlukahlukene, kusukela ku-Atari kuya ku-Gameboy noma i-ZX Spectrum. Ungathenga futhi amacala ahlukahlukene, ama-joystick, njll.

Angikude nokudlala, ngakho-ke angikwazi ukusho ngokuningiliziwe, noma ubani angayizama ngokwakhe. Izifundo ezimbalwa okufanele uzifunde:

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

isiphetho

Ngethemba ukuthi kunemibono emisha eyanele yezinto ongazenza kule mpelasonto. Uma izilinganiso ze-athikili zivuma, ingxenye yesithathu izothunyelwa.

Njengenjwayelo, ukuhlola okujabulisayo wonke umuntu.
