  Yog tias koj mus rau txoj kev no, koj kuj yuav tsum tau ua txoj hlua hluav taws xob, lossis txiav ib txoj hlua txuas ntxiv thiab siv nws ua koj lub hwj huam qaum

• nrog rau koj tus pi nrog tus hloov pauv phaw
• thiab tej zaum txawm tias lub teeb hluav taws xob siab dua yog tias xav tau nrog cov hloov hluav taws xob

Kauj Ruam 2: Teeb Tus Pi 1: Txhim Kho Raspbian

Thawj kauj ruam yog kom tau raspbian ntawm koj lub cuab yeej. Kuv yuav npog tag nrho cov no hauv ib qho thaiv, thiab npog cov cuab yeej sib cais.

Kuv pom zoo rub tawm noob los ntawm pi foundation

Tsuas yog unzip, thiab theej rau koj daim ntawv tshiab micro SD daim npav. Qhov ntawd yog nws. Thaum koj qhib koj tus pi, nws yuav coj koj los ntawm kev teeb tsa.

Kauj Ruam 3: Teeb Tus Pi 2: Teeb SSH thiab VNC

Muaj SSH thiab VNC teeb tsa txhais tau tias koj yuav tsis xav kom tus pi ntsaws rau hauv qhov tsis zoo ntawm cov xov hlau. Txhua yam yuav ua tau los ntawm 2 lub qhov rais ntawm koj lub laptop lossis txawm tias los ntawm koj lub xov tooj. Peb yuav nquag ua ntej peb cov lus txib nrog "sudo", qhov no yeej tseem ceeb muab peb cov lus txib rau tus tswj hwm txoj cai.

1. Ua ntej hloov koj tus password. Qhib lub davhlau ya nyob twg qhov rai thiab ntaus cov hauv qab no thiab koj yuav raug hais kom nkag mus rau tus password tsis raug (raspberry) thiab tom qab ntawd muab koj tus kheej lo lus zais.

   sudo passwd lus

2. tam sim no theej koj tus IP chaw nyob nrog cov lus txib hauv qab no

   ifconfig

Tam sim no mus rau cov ntawv qhia zaub mov, thiab qhib rau SSH thiab VNC. Tam sim no koj tuaj yeem rov pib lub pi thiab tshem nws los ntawm tus saib, keyboard, thiab nas.

Kauj Ruam 4: Teeb Tus Pi 3: Siv Bitvise SSH txhawm rau Nkag Mus Rau Koj Tus Pi

Kuv pom zoo bitvise vim tias nws muaj kev koom ua ke SFTP, nrog rau kev sib cuam tshuam zoo. Nkag mus rau koj tus IP chaw nyob uas koj tau theej ua ntej, siv lub npe siv pi, thiab koj tus password tshiab. Khaws qhov chaw nres nkoj pib (22). Lub davhlau ya nyob twg yuav tsum qhib thaum koj xaiv tus ID nkag mus.

Kauj Ruam 5: Teeb Tus Pi 4: Hloov Kho Koj Tus Pi

Ua ntej koj ua lwm yam, khiav qhov hloov tshiab

1. Ua ntej, koj hloov kho lub tsev qiv ntawv ntawm cov pob khoom twg muaj nrog

   sudo apt-tau hloov tshiab

2. Thaum nws ua tiav, koj yeej nruab qhov hloov tshiab nrog

   sudo apt-tau hloov tshiab

3. Rau qhov ntsuas tau zoo, xyuas kom tseeb tias koj li firmware tau hloov kho tshiab (qhov no yuav tsum tau ua tiav los ntawm kev hloov kho tshiab)

   sudo rpi-hloov tshiab

Kauj Ruam 6: Teeb Tus Pi 5: Txhim Kho Lightshowpi

Ib feem ntawm cov kauj ruam no muaj ncaj qha rau ntawm lub vev xaib lightshowpi. Kuv yuav suav nrog lawv kom yooj yim. Kuv yuav ntxiv qee qhov kev piav qhia nyob rau ntawd.

• sudo apt-tau nruab git-core

  apt-tau yog dab tsi tau txais cov pob khoom, thiab ntawm no peb yuav nruab git-core, kev vam khom (cov haujlwm git-core xav tau los ua haujlwm) yuav cia li ntxiv

• cd ~ ib

  cd yog hloov cov npe, thaum ~ txhais tau tias/tsev/*username*/, qhov no nws yuav yog/tsev/pi/; siv qhov ntawd lossis ~ yuav tsum ua haujlwm ib yam nkaus

• git clone

  Qhov ntawd tsuas yog theej theej cov ntawv tais ceev tseg uas peb xav tau

• cd lightshowpi

  tam sim no peb txav mus rau daim nplaub tshev peb nyuam qhuav rub tawm

• git fetch && git checkout ruaj khov

  tam sim no peb tau txais cov ntaub ntawv xav tau

• cd/tsev/pi/lightshowpi

  peb txav mus rau daim nplaub tshev raug; hauv linux, tshwj tsis yog tias peb tsim cov kab ke sib txuas, peb ib txwm yuav tsum tau txav mus rau qhov raug nplaub tshev ua ntej tso cov ntawv sau

• sudo./install.sh

  qhov no ua qhov kev teeb tsa tiag tiag; qhov no siv sijhawm li 3 teev ntawm kuv tus lej xoom w

• sudo rov pib dua

  tam sim no peb reboot

Kauj Ruam 7: Txuas koj Cov Khoom

Txawm li cas los xij koj kawg ua kom muaj zog rau koj cov cuab yeej nyob ntawm seb koj tab tom siv dab tsi. Muaj ntau txoj hauv kev xaiv ntawm no, tab sis qhov kawg ntawm hnub ntawd, koj yuav xav tau 5v rau koj tus pi, txawm tias dhau los ntawm USB, lossis siv tus pin header thiab kev cai daws teeb meem zoo li kuv tau ua. Txhua lub zog koj tab tom cuam tshuam yuav tsum yog DC. AC kab hluav taws xob yuav ua haujlwm zoo xwb, tab sis nws ua rau muaj kev pheej hmoo ntxiv. Tsawg hluav taws xob nyob nyab xeeb dua.

Kauj Ruam 8: Txuas Koj Cov Khoom 2: Soldering Pins

Yog tias koj siv tus lej xoom, koj yuav tsum tau xaum lub taub hau taub hau, lossis txuas cov xov hlau ncaj qha ntawm tus pin qhov lawv tus kheej.

Kauj Ruam 9: Txuas Koj Cov Khoom 3: Txuas Tus Pi mus rau Pawg Neeg Tawm Tswv Yim

Peb siv wiringpi tus lej tus lej. Muaj lwm txoj hauv kev rau npe lub rooj sib tham nyob ntawd, tsuas yog siv daim ntawv uas kuv tau muab, lossis mus rau wiringpi.com

Los ntawm pawg thawj coj saib xyuas, nrog tus pin rau koj, ntawm sab laug mus rau sab xis, koj yuav txuas rau cov hauv qab no ntawm pi

1. pin 20: Ground
2. pin 11: GPIO 0
3. pin 12: GPIO 1
4. pin 13: GPIO 2
5. pin 15: GPIO 3
6. pin 16: GPIO 4
7. pin 18: GPIO 5
8. pin 22: GPIO 6
9. pin 7: GPIO 7
10. pin 4: 5 v

Yog tias koj tab tom txhawb koj tus pi los ntawm tus pin header, tom qab ntawd +5v yuav mus rau tus pin 2, thiab - (hauv av) yuav mus rau tus lej 6.

Kauj Ruam 10: Txuas Koj Cov Khoom 4: Txuas Koj Cov Txuas

Cov relays ua haujlwm zoo li hloov. Txawm li cas los xij koj yuav xaim koj lub teeb ncaj qha rau koj lub zog, ua li ntawd, tab sis tom qab ntawd txiav cov xov hlau nyob thiab tso txhua qhov kawg ntawm cov xaim txiav ntawm ib qho ntawm kev xa tawm. Txhua qhov kev tshaj tawm muaj 3 lub davhlau ya nyob twg. 2 ntawm lawv nyob ua ke, thiab ua kom lub zog sib txuas sib cais lawv, lwm qhov txuas nrog rau lub davhlau ya nyob twg nruab nrab thaum lub zog xa tawm. Daim duab me me ntawm lub ces kaum zoo qhia koj tias ib qho twg yog cais (hauv liab). Qhov kev tawm tsam xaus (thawj thiab zaum kawg) ntawm txhua qhov kev sib txuas yuav tsis txuas nrog. Yog tias koj xav tau, koj tuaj yeem ua ib txwm-siv thiab siv 2 hauv qhov ntsuab, nws tsuas yog txhais tau hais tias lub teeb pom kev zoo yuav rov qab. Tej zaum nws yuav muaj txiaj ntsig yog tias koj xav kom lub teeb teeb rau tom qab lub suab paj nruag xaus.

Kauj Ruam 11: Xeem Nws

Kuv siv cov LED me me no los ntsuas kuv lub rooj tsavxwm, tab sis tiag tiag koj tuaj yeem tsuas yog saib lub teeb liab uas nyob ntawm pawg thawj coj saib xyuas. Txhua qhov kev tshaj tawm twb muaj nws tus kheej LED.

• Tsis txhob hnov qab mus rau lub nplaub tshev lightshowpi ua ntej

  cd/tsev/pi/lightshowpi/

• Tom qab ntawd siv ib qho ntawm cov lus txib ntsuas no

  • sudo python py/hardware_controller.py -xeev = flash
  • sudo python py/hardware_controller.py -xeev = ploj mus

Txhawm rau xaus qhov ntsuas, siv CTRL+C

Kauj ruam 12: Txaus siab rau

Tam sim no nws yog lub sijhawm los teeb koj lub teeb Christmas tiag tiag, thiab txaus siab rau qhov ua yeeb yam. Tsis txhob hnov qab mus saib kuv cov vis dis aus tag nrho!

Txhawm rau khiav koj thawj zaj nkauj, siv cov ntaub ntawv demo muab los ntawm lub teeb pom kev zoo devs

sudo python py/synchronized_lights.py --file =/home/pi/lightshowpi/music/sample/ovenrake_deck-the-halls.mp3

Txhawm rau ua lwm tus tub, tsuas yog hloov lub npe ntawm mp3 ntawm qhov kawg ntawm cov lus txib ntawd. Nov yog qhov uas sftp feature ntawm bitvise tuaj; koj tuaj yeem yooj yim nyem thiab rub koj cov ntaub ntawv.
