Qhov tseem ceeb tsis zoo yog mus rau sab nraub qaum thiab qhov zoo yog mus tom ntej. Yog tias koj tau txais lawv lwm txoj hauv kev puag ncig, lub tank tsuas yog tsav hauv qhov kev coj rov qab uas yooj yim kho hauv software.
Kauj ruam 4: Programming
Yog li rau cov kauj ruam no peb yuav xav tau teeb tsa ob peb yam yog tias koj tsis tau ua dua.
- Raspian
- Nab hab sej 2 lossis 3
- Git
- MJPG-Tshaj tawm
Txhim kho Raspian
Ua ntej tshaj peb yuav tsum muaj Raspian ntawm daim npav micro SD, yog li muaj daim ntawv SD tsawg kawg 8GB npaj (Koj tseem tuaj yeem nruab NOOBS lite yog tias koj tsuas muaj 4GB daim npav).
Txhawm rau nruab Raspian Kuv xav kom siv NOOBS. Qhov txuas txuas yog nyob ntawm no. Rub tawm cov ntawv zip rau hauv koj lub PC, thiab rho cov ntawv rau hauv daim npav sd. Nco ntsoov cov ntaub ntawv thiab cov ntawv tais ceev tseg muaj thiab tsis nyob hauv daim nplaub tshev noobs.
Thaum koj tau ua tiav qhov no, ntsaws daim npav SD rau hauv Raspi 3, txuas lub vijtsam (Lub TV nrog HDMI ua haujlwm tau zoo yog tias koj tsis muaj tus saib) thiab keyboard thiab nas.
Koj yuav tsum pom lub vijtsam teeb tsa nruab, txuas rau wifi (wifi xav tau rau txoj haujlwm no kom ua haujlwm) thiab teeb tsa, Kuv tsuas yog siv lub teeb tsa ua ntej vim lawv ua haujlwm tau zoo.
Kev teeb tsa rau hom tsis muaj hau
Yog li thaum Raspian tau teeb tsa thiab koj tau nkag mus rau hauv Raspi 3, koj tuaj yeem pib teeb tsa Raspi 3 kom khiav hauv lub taub hau hom (piv txwv li siv SSH hloov lub vijtsam thiab keyboard). Tsuas yog daim ntawv koj yuav tsum tau siv sudo thiaj li paub tseeb tias koj paub lub hauv paus lo lus zais.
Qhib lub davhlau ya nyob twg thiab ntaus 'sudo raspi-config', koj yuav tsum muaj lub vijtsam xiav thiab txho zoo li hauv cov duab. Tsiv mus rau 'Kev xaiv cuam tshuam', nias nkag mus, tom qab ntawd txav mus rau 'P2 SSH' nias nkag mus thiab nkag dua rau 'yog', dua rau 'ok'.
Tam sim no rov qab mus rau hauv 'cuam tshuam kev xaiv' thiab qhib lub koob yees duab.
Rov qab rau hauv cov ntawv qhia zaub mov nyem sab xis thiab nkag mus xaiv 'ua tiav'.
Tom ntej no peb yuav tsum nrhiav peb tus IP chaw nyob, koj tuaj yeem ua qhov no los ntawm kev ntaus 'ifconfig' rau hauv lub davhlau ya nyob twg. Nrhiav qhov thaiv pib nrog wlan0 (feem ntau yog qhov kawg) thiab sau cia koj tus IP chaw nyob. Nws yuav tsum yog ntawm kab thib ob thiab saib qee yam zoo li qhov no 192.168.1. XX yog tias koj siv koj lub wifi hauv tsev.
Zoo kawg uas yog qhov kawg ntawm kev teeb tsa
Txhim kho software ntxiv
Yog li, txhawm rau sau cov ntawv kuv muaj, koj yuav tsum muaj cov nab hab sej 2 lossis 3 teeb tsa. Yog tias koj xav kawm nab nab, Kuv xav kom koj kawm nab nab 3, qhov sib txawv yog qhov me me tab sis nab nab 3 tam sim no tau siv ntau dua. Nws yuav tsum tuaj ua ntej nruab nrog Raspian tab sis peb yuav tsum cia li kos ob zaug.
Hom 'nab hab sej -hloov pauv', koj yuav tsum tau txais cov zis zoo li 'Python 2.7.13' uas txhais tau tias koj tau nruab nab nab 2. Txhawm rau txheeb xyuas yog tias koj muaj nab nab 3 tsuas yog ntaus 'python3 --version' thiab koj yuav tsum tau txais cov txiaj ntsig zoo sib xws. Yog tias koj tsis muaj nab hab sej 2 lossis 3, koj tuaj yeem ntaus 'sudo apt-get install sej' lossis 'sudo apt-get install python3', hwm.
Koj tseem yuav xav tau Git kom tau txais txoj cai, dua, nws yuav tsum tau teeb tsa ua ntej. Ntaus 'git --version' txhawm rau txheeb xyuas thiab siv 'sudo apt-get install git' yog tias koj tsis muaj nws.
