Njira 5 zothandiza zogwiritsira ntchito Raspberry Pi. Gawo lachiwiri

Pa Habr.

В gawo loyamba Njira 5 zogwiritsira ntchito Raspberry Pi zidaganiziridwa. Mutuwu udakhala wosangalatsa kwambiri, ndipo lero ndiwona zosankha zingapo zamomwe mungagwiritsire ntchito kompyuta yaying'ono iyi kuti ikuthandizeni.

Chithunzi kuchokera patsamba learn.adafruit.com

Monga gawo lapitalo, ndiwona njira zomwe sizikufuna kupanga mapulogalamu.
Kwa iwo omwe ali ndi chidwi, kupitiriza kuli pansi pa kudula.

1. Kamera yoyang'anira

Raspberry Pi itha kugwiritsidwa ntchito ndi pafupifupi makamera onse otetezera.
Zotsatirazi zitha kugwira ntchito ndi Raspberry Pi:

• Makamera awebusayiti a USB (monga Logitech C910)
• Makamera a IP (Axis, etc.) okhala ndi jekeseni ya PoE (mphamvu ya 48V imaperekedwa ku makamera oterowo kudzera pa chingwe cha netiweki, chomwe chimawalola kusuntha kunja kwa nyumbayo)
• makamera omwe amalumikizana mwachindunji ndi cholumikizira pa RPi (monga pa chithunzi pamwambapa).

Pali ndithu zambiri zimene mungachite kuti mwamakonda pulogalamuyo pano. Mutha kugwiritsa ntchito paketi Zoyenda, yomwe ili ndi makonda osinthika. Mutha kulemba mwachindunji kuchokera ku kontrakitala pogwiritsa ntchito ffmpeg, kapena mutha kulemba chogwirizira chanu pogwiritsa ntchito Python ndi OpenCV. Mutha kuwulutsa mtsinje wamavidiyo, kugwiritsa ntchito kuzindikira koyenda, kutumiza zithunzi ndi imelo, ndi zina.

Amene ali ndi chidwi akhoza kuwonera maphunziro awa:

chofunika: Zinatchulidwa kale mu gawo lapitalo, koma ndi bwino kubwereza. Pazochita zilizonse zofunika kwambiri (zomwe zimaphatikizapo kukonza makanema) pa Raspberry Pi, magetsi apamwamba kwambiri amtundu wa 2.5A amafunikira ndipo heatsink yopanda kanthu pa CPU ndiyofunika (mutha kuyipeza yotsika mtengo ku China $ 1- 2 pofufuza rasipiberi pi heatsink). Kupanda kutero, chipangizocho chikhoza kuzizira, zolakwika zokopera mafayilo zitha kuwoneka, ndi zina.

2. Kujambula mawu

Ndi maikolofoni ya USB, Raspberry Pi itha kugwiritsidwa ntchito ngati cholakwika komanso chida chojambulira chomveka bwino. Apanso, pali njira zambiri zosinthira pulogalamuyo - mutha kulemba mafayilo kwanuko ku SD khadi, mutha kuwulutsa ku PC ina, kapena kuwulutsa pa netiweki.

• www.heidislab.com/tutorials/audio-streaming-with-raspberry-pi-zero-w-and-adafruits-i2s-mic

Mwa njira, ngati muli ndi maikolofoni, Raspberry Pi angagwiritsidwe ntchito Amazon Alexa ndikugwiritsa ntchito chipangizochi polamula mawu.

3. Prof. chithunzi

Osasokoneza p3 ndi p1. M'ndime yoyamba tinkakamba za makamera owonetsera mavidiyo, koma Raspberry Pi amathanso kuyang'anira makamera akatswiri kuchokera ku Canon, Nikon, Sony, etc. Kamera imangofunika kugwirizanitsidwa ndi Raspberry Pi kudzera pa USB.

Chithunzi kuchokera patsamba www.movingelectrons.net/blog/2017/08/09/Camera-Time-lapse-Controller-with-Python-and-Raspberry-Pi.html

Malaibulale gphoto2 и libgphoto2 khalani ndi mphamvu zonse zogwirira ntchito kuchokera pamzere wamalamulo ndi zolumikizira za Python ndi C ++, zomwe zimakulolani kugwiritsa ntchito Raspberry Pi kuwongolera "DSLR", mwachitsanzo, kujambula kwanthawi yayitali. Mndandanda wa makamera othandizira Ndi yayikulu mokwanira ndipo imaphimba pafupifupi mitundu yonse, kuyambira masiku ano mpaka akale kuyambira zaka 10 zapitazo. Libgphoto2 ili ndi zokwanira API yapamwamba, ndipo sangangowongolera chotseka, komanso kusintha makonda, kukweza mafayilo, ndi zina.

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

Mwa njira, mutha kulemba zithunzi ku memori khadi ya kamera kapena mwachindunji ku Raspberry Pi, zomwe zimalola, mwachitsanzo, kuziyika zokha ku "mtambo". Palinso malaibulale owongolera osati makamera a SLR okha, komanso zakuthambo (mwachitsanzo ZWO ASI) makamera, kuphatikiza ngakhale autoguiding.

4. Malo okwerera nyengo

Raspberry Pi "akhoza" osati kuyendetsa mapulogalamu a Linux okha, komanso ali ndi zotumphukira zowoneka bwino - serial, I2C, SPI, GPIO. Izi zimapangitsa chipangizochi kukhala choyenera kusonkhanitsa ndi kutumiza deta kuchokera ku masensa osiyanasiyana - kuchokera ku masensa a kutentha ndi chinyezi kupita ku dosimeter yotengera Geiger counter.

Chithunzi kuchokera patsamba www.raspberrypi.org/blog/build-your-own-weather-station

Mwa njira, ngati mutakhala waulesi kwenikweni, simungatenge deta kuchokera ku masensa anu okha komanso kuchokera pa intaneti, njirayi ilinso ndi ufulu wokhalapo. Komabe, bolodi yokhala ndi masensa a Raspberry Pi siwovuta kugula padera.

5. Masewera amasewera

Kugwiritsa ntchito polojekiti RetroPie mutha kusintha Raspberry Pi kukhala "retro" emulator yamasewera osiyanasiyana, kuchokera ku Atari kupita ku Gameboy kapena ZX Spectrum. Mukhozanso kugula milandu yosiyanasiyana, joystick, etc.

Ndili kutali ndi masewera, kotero sindingathe kunena mwatsatanetsatane, aliyense akhoza kuyesa yekha. Mfundo ziwiri zofunika kuziganizira:

• thewirecutter.com/reviews/raspberry-pi-game-console

Pomaliza

Ndikukhulupirira kuti pali malingaliro atsopano okwanira pazomwe mungachite kumapeto kwa sabata ino. Ngati mavoti a nkhaniyo ali abwino, gawo lachitatu lidzatumizidwa.

Monga mwachizolowezi, mayesero osangalala aliyense.
