RuuviTag thiab PiZero W thiab Blinkt! Bluetooth Beacon Raws Tus Ntsuas Kub: 3 Kauj Ruam (nrog Duab)

2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:27

Cov lus qhia no piav qhia txoj hauv kev los nyeem cov ntaub ntawv ntsuas kub thiab av noo los ntawm RuuviTag siv Bluetooth nrog Raspberry Pi Zero W thiab los tso saib qhov tseem ceeb hauv tus lej binary ntawm Pimoroni blinkt! pHAT. Or los muab nws luv luv: yuav ua li cas thiaj tsim tau lub xeev ntawm kev kos duab thiab tus pas ntsuas kub me ntsis.

RuuviTag yog qhov qhib qhov qhib sensor bluetooth lub teeb uas los nrog qhov ntsuas kub/av noo/siab thiab ntsuas lub ntsuas cua, tab sis kuj tseem tuaj yeem ua raws li tus qauv Eddystone ™/iBeacon sib thooj teeb liab. Nws yog qhov haujlwm Kickstarter ua tiav thiab kuv tau txais kuv li ob peb lub lis piam dhau los. Muaj Github nrog nab hab sej software los nyeem RuuviTag siv raspberry, thiab kuv tau siv ib qho ntawm lawv cov piv txwv, nrog qee qhov ntxiv.

Raspberry Pi Zero W yog tus tswv cuab tshiab ntawm RPi tsev neeg, ib txwm yog Pi Zero nrog Bluetooth thiab WLAN ntxiv.

Lub blinkt! pHAT los ntawm Pimoroni yog ib puag ncig ntawm yim RBG LEDs teeb tsa ua HAT rau Raspberry Pi. Nws yog qhov siv tau yooj yim heev thiab los nrog lub tsev qiv ntawv sej. Lub tswv yim yog nyeem cov ntaub ntawv los ntawm RuuviTag thiab tso saib nws siv lub ntsais muag! HAT. Cov txiaj ntsig tau muab tso tawm ua tus lej binary siv 7 ntawm LEDs, thaum yim siv los qhia tias cov av noo lossis qhov kub (+/-/0) qhov txiaj ntsig tau tshwm sim.

Kauj ruam 1: Teeb tsa Qhov System

Teeb tsa cov txheej txheem yog yooj yim:- Hloov ntawm RuuviTag (RuuviTag qhov ntsuas kub ntsuas qhov ntsuas).

- Teeb koj li RPi Zero W, RPi3, lossis lwm yam RPi nrog lub peev xwm bluetooth ntxiv, ua raws cov lus qhia ntawm www.raspberrypi.org.

- Tso lub blinkt! HAT ntawm RPi (thaum tawm).

- Nruab lub blinkt! thiab RuuviTag software, raws li qhia hauv cov nplooj ntawv sib xws GitHub.

- Tam sim no koj yuav tsum txheeb xyuas MAC chaw nyob ntawm koj RuuviTag

- luam qhov program Python uas txuas nrog, qhib nws nrog IDLE rau Python 3

- hloov MAC chaw nyob ntawm RuuviTag rau koj li, tom qab ntawd txuag thiab ua haujlwm qhov program.

- xav tias hloov kho thiab ua kom zoo dua qhov program. Qhov kev zov me nyuam los raws li nws yog, siv los ntawm koj tus kheej txoj kev pheej hmoo, tsis muaj kev lav phib xaub rau ib qho kev puas tsuaj.

Kauj Ruam 2: Ntaus Ntawv thiab Txoj Haujlwm

Raws li tau hais los saum toj no, lub tswv yim yog los tsim cov txheej txheem yooj yim thiab pheej yig los nyeem cov ntaub ntawv los ntawm lub teeb thiab teeb tus lej lej ntawm qhov ntsais! HAT, lossis zoo ib yam LED sawb.

Qhov ntau ntawm qhov ntsuas kub yuav raug ntsuas nrog RPi raws qhov system feem ntau yuav nyob qhov twg ntawm - 50 ° C thiab +80 ° C, rau cov av noo ntawm 0 thiab 100%. Yog li cov zaub uas tuaj yeem muab qhov tseem ceeb ntawm -100 txog +100 yuav txaus rau feem ntau daim ntawv thov. Cov lej zauv me me li 128 tuaj yeem tso tawm ua tus lej binary nrog 7 khoom (lossis LEDs). Yog li qhov kev zov me nyuam siv qhov ntsuas kub thiab av noo los ntawm RuuviTag li "ntab" tus lej thiab hloov pauv lawv mus rau tus lej binary, uas tom qab ntawd tshwm rau ntawm qhov ntsais!

Ua thawj kauj ruam, tus lej tau muab sib npaug, tshuaj xyuas yog tias zoo, tsis zoo lossis xoom, thiab tom qab ntawd hloov pauv mus rau tus lej zoo siv "abs". Tom qab ntawd tus lej zauv tau hloov pauv mus rau 7-tus lej binary tooj, feem ntau yog txoj hlua ntawm 0s thiab 1s, uas tau tshuaj xyuas thiab nthuav tawm ntawm 7 pixels kawg ntawm qhov ntsais!

Txog qhov ntsuas kub thawj pixel qhia yog tias tus nqi zoo (liab), xoom (magenta) lossis tsis zoo (xiav). Qhia cov av noo qhov tseem ceeb nws tau teeb rau ntsuab. Txhawm rau ua kom yooj yim kev ntxub ntxaug ntawm qhov kub thiab txias qhov tseem ceeb binary pixels tau teeb tsa dawb rau qhov kub thiab daj rau cov av noo. Txhawm rau txhim kho kev nyeem tau ntawm cov lej binary, "0" pixel tsis tau muab tua tag nrho, tab sis hloov pauv tau teeb tsa ntau dua li hauv "1" xeev. Raws li blinkt! pixels yog qhov ci ntsa iab, koj tuaj yeem teeb tsa qhov dav dav hloov pauv qhov ntsuas "ci"

Qhov kev zov me nyuam qhia qhov muaj nuj nqis thiab ib feem ntawm cov txheej txheem tseem nyob ntawm qhov screen. Ib qho ntxiv koj yuav pom ob peb lub suab ntsiag to (#) luam tawm cov lus qhia. Kuv tso lawv rau hauv, zoo li koj yuav pom lawv pab tau kom nkag siab cov txheej txheem yog tias tsis muaj suab npe.

Qhov tseem ceeb kuj tseem yuav muab khaws cia rau hauv cov ntaub ntawv teev cia.

Kauj Ruam 3: Txoj Cai Code

Cov cai tau debugged me ntsis thiab ua kom zoo dua. Tam sim no koj tuaj yeem pom version 3 (20_03_2017).

'Qhov haujlwm no yog npaj los nyeem qhov ntsuas kub, av noo thiab ntsuas qhov ntsuas tsim RuuviTag' 'thiab txhawm rau ntsuas qhov ntsuas kub thiab av noo raws li tus lej binary ntawm Pimorini blinkt! HAT. '' '' Nws yog raws li print_to_screen.py piv txwv los ntawm lub tsev qiv ntawv ruuvitag ntawm github. '' Yuav tsum muaj Pi Zero W, Pi 3 lossis lwm yam RPi nruab nrog bluetooth thiab txhua lub tsev qiv ntawv tsis tuaj yeem teeb tsa. '
