3. ”
The Raspberry Pi is a credit-card
sized computer designed for kids to
experiment with and learn to
program and learn about
embedded Linux systems.

4. What is a Raspberry Pi?
It's tempting to think of the Raspberry Pi as a microcontroller development
board like Arduino, or as a laptop replacement. In fact it is more like the
exposed innards of a mobile device, with lots of maker-friendly headers for
the various ports and functions.

5. What’s on the board
▹(A) Processor: a 32 bit 700 MHz SoC
▹(B) SD Card slot: Hard drive
▹(C) USB ports: USB 2.0
▹(D) Ethernet port
▹(E) HDMI Connector
▹(F) Status LEDs
▹(G) Analog Audio Out: high impedance loads
▹(H) Composite Video: NTSC or PAL
▹(I) Power input
5

6. What’s on the board
▹(A) General Purpose Input Output (GPIO)
▹(B) Display Serial Interface (DSI) connector
▹(C) Camera Serial Interface (CSI) connector
▹(D) JTAG testing header for the Broadcom chip
and the LAN9512 networking chip
6

7. What is needed to get it up and running
▹A power supply: microUSB adapter which provides 5 V (5,2 V) at 1 A
▹An SD Card: at least 4 GB Class 4
▹An HDMI cable
▹Ethernet Cable: alternative is a USB WiFi adapter
7

8. Operating System
▹Runs Linux as an operating system (Kernel)
▹A variety of avors or distributions of the OS Linux have evolved over the years like
Ubuntu, Debian, Fedora, etc.
▹Special distributions for Raspberry Pi
-Raspbian (Ocially Recommended)
-Adafruit Raspberry Pi Educational Linux
-Arch Linux
-Xbian (XMBC media center)
-QtonPi, etc …
▹A disk image is required to install the OS onto the Pi
▹Since June 2013, the NOOBS (New Out Of the Box Software) utility was developed to
simplify the OS installation and recovery process
8

9. Lets get started !
▹ Format SD card (4GB+)
▹ Download Win32DiskImager
▹ Copy extracted files onto formated SD card
▹ Insert SD card into Pi
▹Connect keyboard, mouse and HDMI cable
▹ Plug in the power supply
▹The Pi will take about 5 mins to boot up

10. BOOT UP
10

11. Start the desktop behavior
▹Log in: Pi
▹Password: raspberry
▹Raspbian comes with the Lightweight X11
Desktop Environment (LXDE) graphical
desktop environment installed.
▹Now a new version of Desktop « Pixel »

13. Part 2
Linux
13

14. Introduction
▹If you're going to get the most out of your RPi, you'll need to learn a little
Linux
▹It's quite difficult to determine which commands we should learn you,
because there are so much commands in the Linux world.
▹In what follows we try to give you the basics.
14

15. Opening a terminal
▹There are 2 possibilities:
-Using the GUI: The desktop icon
-By command: Alt + F2 -> type “rxvt” -> press Enter
▹You can leave the command prompt by typing exit or crtl-d
15

16. Important!
▹Once booted, be carefull. There is no button for powering off the system.
▹Do not eliminate the power when the system is running. You can damage
the le system on the SD-card.
▹You can shutdown the system from the command prompt by typing :
sudo shutdown -h now
▹Sudo stands for 'superuser do'. You have to be root for executing
▹some Linux commands. For instance for:
▹update the system: sudo apt-get update
▹upgrade the system: sudo apt-get upgrade
▹installing software: sudo apt-get install mysoftware
▹removing les/software: sudo apt-get remove myfile/software

17. Part 3
Remote login over SSH
17

18. Remote login over SSH
▹Sometimes it isn’t necessary or possible to connect the RPi with a
display/screen.
▹Then you can login on your RPi by means of SSH: ssh pi@IpAdres
▹That’s a manner to work by commandprompt
▹Suppose that the Graphical environment crashes, you still have a possibilty
to shutdown the RPi, from another pc, whitout damaging the file system
18

19. Part 4
Copying Files: Local  Remote
19

20. Introduction WinSCP
▹For Windows users
▹WinSCP is a free open-soure SFTP, FTP and SCP client for Microsoft
Windows
▹FTP : File Transfer Protocol
▹SFTP : Secure File Transfer Protocol
▹SCP : Secure CoPy
▹It’s main function is secure file transfer between a local and remote
computer
20

21. Installation WinSCP
▹Take care that the SSH server is installed on your RPi:
▹sudo apt-get install openssh-server
▹Search a WinSCP download file on the web and install it
▹Open WinSCP
▹Enter your:
▹IP-address: Which you have noticed previously
▹Username: pi
▹Password: raspberry
▹Portnumber: 22
21

22. Introduction SCP
▹For Linux users
▹For copying files over SSH it’s neccessary installing an SSH server on the
RPi: sudo apt-get install openssh-server
▹SSH is a cryptographic network protocol for secure data communication,
remote command-line login, remote command execution, and other secure
network services between two networked computers that connects, via a
secure channel over an insecure network, a server and a client.
22

23. Introduction SCP
▹Please do note that some linux OS may come with SCP pre-installed, but the
Raspbian that we were using, didn't have it. The general command to send a
single file is:
scp (path of file on local device) pi@192.168.3.215 (path of remote
location)
▹Example :
scp /pi/example.cpi@192.168.3.215 /pi/project
For Many files :
scp -r /pi/project pi@192.168.3.216 /pi/project

24. Part 5
VNCServer - VNCViewer
24

25. Introduction
▹The RPi is an very interesting system, but there is a lot of extra hardware
required. Like a keyboard, mouse, screen, UTP cable, power cable, etc.
▹You can eliminate a lot of hardware after you’re RPi is configured the first
time
▹There is a possibility to login on your RPi from another computer. Therefore
you must install a VNCserver on your Pi and a VNCviewer on your computer.
25

26. Introduction
▹VNC → Virtual Network Computing
▹It’s a graphical desktop sharing system
▹Another computer can be managed remotely
▹It transmits keyboard and mouse events from an computer to another
▹The graphical screen updates back in the other direction, over a
computernetwork
26

27. Installation VNCserver
▹Install the VNCserver on your RPi, type following command:
sudo apt-get install tightvncserver
▹Once installed, take care that the VNCserver will automatically startup
everytime the RPi will be booted.
▹Start the VNCserver a first time: sudo tightvncserver
▹VNC will ask once only after a password: raspberry
▹On the question
▹’would you like to enter a view-only password (y/n)?’
Answer no (n)
27

28. Installation VNCviewer
▹Install VNCviewer on your Windows computer
▹Search a download file on the web and install it
▹Install VNCviewer on your Linux computer
▹sudo apt-get install xtightvncviewer
▹Open xtightvncviewer: xtightvncviewer
▹A popup window will appear
▹Enter the IP-address of your RPi followed by the portnumber (5901),
ex.: 12.123.12.12:5901
▹A new popup window will emerg for entering your password
▹Test it.
