Introduction

I've set up the Raspberry Pi many times, but each time I've been searching for a setup method. Some people want to share information, so I'll try to summarize it myself.

I wrote SSH settings.

Necessary equipment

First, prepare what you need.

Windows PC (you can do it on mac, but I don't own it, so I'll omit it)
RaspberryPi3 Model B
micro SD card (8GB or more recommended)
HDMI cable
Display (HDMI compatible)
microUSB cable
Keyboard
Mouse

1. Download OS image

Download the required OS image from the following site. Original site

Many OSs are open to the public, but this time I will download Raspbian.

There are two types, DESKTOP and LITH, but they have the following features.

DESKTOP: A desktop environment is included as standard, for beginners LITH: Lightweight and server-friendly only in CUI environment

This time, select the DESKTOP version. Click the link below to start the download. RASPBIAN STRETCH WITH DESKTOP 2018-04-18

Unzip the downloaded image with the tool.

As of May 25, 2018, kernel version 4.14 is the latest.

2. Write the OS image to the SD card

Install Win32 Disk Imager
Insert the microSD card into your PC
Launch the app and specify the OS image you downloaded earlier in Image File and the drive on which the SD card is mounted in Device.

Please be sure not to make a mistake in Device. I accidentally specified a USB stick and overwrote the file. .. .. ..

Click the Write button to write

3. Start Raspberry Pi

Insert the SD card Insert the microSD card containing the OS image into the Raspberry Pi. 　
Connect the HDMI cable
Plug in the micro USB cable

4. Turn on the power If the green LED flashes, the Raspberry Pi is on. The red LED will illuminate when the Raspberry Pi is connected, regardless of whether it is powered on. 20180527_083657 --Copy.jpg 　 5. Check the display When you start Raspberry Pi, the following screen will be displayed. The startup is now complete. 2018-05-22-131458_1824x984_scrot --copy.png

4. Make initial settings

1. Open the setting screen

Start the terminal and execute the command Click the black icon at the top left of the screen.
Enter the command in the terminal

$ sudo raspi-config

2018-05-22-131629_631x270_scrot --copy.png

Enter the command and press the Enter key to open the screen below. Make various settings on this screen. 2018-05-22-131702_783x375_scrot --Copy.png

2. Extend the microSD card partition

Select 7 Advanced Options. You can move the cursor with the arrow keys and select with Enter. 2018-05-22-223015_783x375_scrot --Copy.png

Select A1 Expand Filesystem. 2018-05-22-223022_783x375_scrot --Copy.png

This completes the partition expansion. 2018-05-22-223031_783x375_scrot --Copy.png

3. Change location

Japanese localization

Select "4 Localization Options Set up ......". 　　 Select I1 Change Locale. 　

Add * with the Space key according to "ja_JP.UTF-8 UTF-8". Use the Tab key to move to and the Enter key to confirm. 　

Select "ja_JP.UTF-8". 　

This completes the Japanese localization. It will switch to Japanese by restarting, but restarting will be done after all the initial settings are completed.

2. Set the time zone to Japan

Select I2 Chage Timezone. 　

Select "Asia". 　

Select "Tokyo". 　

The time is now Japan time.

1. Keyboard settings Select I3 Change Keyboard Layout.

Select "Generic 105-key (Intel) PC". 　

When the US key setting appears, select "Other". 　

Select "Japanese". 　

Select "Japanese --Japanese (OADG 109A)". 　

Select The default for the keyboard layout. 　

Select No compose key. 　

Select "No". 　

This completes the keyboard settings.

Four. Wifi settings (country) Select I4 Change Wi-fi Country. 　

Select "JP Japan". 　

Select "OK". 　

4. Change interface options

1. Enable camera module Select Interfacing Options.

Select P1 Camera. 　

Select . 　

The camera module is now enabled. In addition, let's enable SSH, I2C, etc. as needed.

5. Internet connection

Select 2 Network Options. 　

Select "N2 Wi-fi". 　

Enter the SSID of the network you want to connect to. 　

Enter your password. 　

This completes the wifi settings.

6. Reboot

Select "Finish". 　

If a reboot is requested, it will be rebooted.

This completes the initial settings. Thank you for your hard work. If you back up the OS image after this initial setting is completed, you can save the trouble of initial setting from the next time.

5. Software update

1. Update package list

$ sudo apt-get update

Update installed packages

$ sudo apt-get upgrade

1. Upgrade dist to the latest version

$ sudo apt-get dist-upgrade

Steps 1 and 2 should be done every time you start the Raspberry Pi.

HelloWorld Well, the initial setting is finally completed. Next, I would like to display the customary Hello World. This time, we will use Python and C, which are often used in Raspberry Pi.

Hello World in Python

Launch the editor

This time I will use vi, but please use your favorite editor. It is easy to use "nano" for CUI base and "gedit" for GUI base. Python3 (IDLE) is included by default as an integrated development environment.

Installation is required when using editors such as vim and nano

$ sudo apt-get install vim
$ sudo apt-get install nano

coding

Start a text editor and write the program.

$ vi hello.py

`hello.py`


print ("Hello World")

1. Run Python is a scripting language, so no compilation is required.

$ python3 hello.py
Hello World

Hello World in C

1. Launch the editor

$ vi hello.c

coding

`hello.c`


#include <stdio.h>

int main(){
  printf("Hello World\n");
  return 0;
}

1. compile

$ gcc -o hello hello.c

Four. Run

$ ./hello
Hello World

7. Summary

This completes the initial setup of Raspberry Pi and Hello World. How was it? The initial settings are difficult, but once you do it, it won't be long. We recommend that you keep a backup.

This time I only displayed Hello World, but you can also do L Chika in Python or C language. I will write about this later.

see you.
