smonto l’sdcard
umount /dev/sdb1 umount /dev/sdb2
installo l’immagine (usare dcfldd per vedere il progresso)
sudo dd bs=4M if=2015-11-21-raspbian-jessie.img of=/dev/sdb
assicuriamoci che non ci siano scritture ancora in atto. Se non funziona prova 1M, prenderà di più
sync
ora possiamo smontare la sdcard e partire.
dd if=/dev/sdb of=sd.img bs=4M sudo dd if=/dev/sdb of=~/Downloads/160726_backupPi.img bs=1M
o 1M nel caso l’abbiate

sudo apt-get install minidlna sudo cp /etc/minidlna.conf /etc/backup_minidlna.conf sudo nano /etc/minidlna.conf
In the configuration file, add
db_dir=/home/pi/minidlna media_dir=/media/raspberry_ext_hd/dlna_dir/ log_dir=/var/log
Add as many media directories as you need. Change names of drives as needed.
mkdir /var/cache/minidlna sudo service minidlna force-reload cat /var/log/minidlna.log
Per testare i files:
sudo apt-get install samba samba-common-bin sudo cp /etc/samba/smb.conf /etc/samba/backup_smb.conf sudo nano /etc/samba/smb.conf
Find workgroup, and modify its value. This is the workgroup your Windows machine need to be a part of to view the files.
workgroup = WORKGROUP netbios name = RaspBPi
Remove irrelevant drives, printers if you don’t need them Add your own drive:
[raspberry_ext_hd] comment = External Raspberry Drive valid users = pi path = /media/raspberry_ext_hd create mask = 0777 directory mask = 0777 read only = No
read only option depends on whether you want your users to change files or not. In my case, I chose yes.
Con il seguente comando abilito ad una PW samba un utente già nel sistema.
sudo smbpasswd -a marco
Se voglio avviungere un utente samba:
sudo useradd -m -g users -p 123456789 marco
Non mi resta che riavviare il servizio
sudo service smbd restart
You configure
At the prompt, enter the following command:
sudo nano /etc/network/interfaces
In the nano text editor, you’ll see something like this:
auto lo
iface lo inet loopback iface eth0 inet dhcp
That’s the very basic configuration that governs your Pi’s Ethernet connect (indicated by the eth0 portion). We need to add on a very minor bit to enable the Wi-Fi dongle. Use the arrow keys to move down below the existing entry and add the following lines:
allow-hotplug wlan0 iface wlan0 inet dhcp wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf iface default inet dhcp
Once you’ve annotated the file, press CTRL+X to save the file and exit the nano editor. At the prompt again, enter the following command:
sudo nano /etc/wpa_supplicant/wpa_supplicant.conf
Compare the contents of the file, if it exists, to the following code. If the file is empty, you can use this code to populate it. Take note of the commented lines (indicated by the # marks) to reference which variable you should use based on your current Wi-Fi node configuration.
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev update_config=1
network={
ssid="YOURSSID"
psk="YOURPASSWORD"
# Protocol type can be: RSN (for WP2) and WPA (for WPA1) proto=WPA
# Key management type can be: WPA-PSK or WPA-EAP (Pre-Shared or Enterprise) key_mgmt=WPA-PSK
# Pairwise can be CCMP or TKIP (for WPA2 or WPA1) pairwise=TKIP
#Authorization option should be OPEN for both WPA1/WPA2 (in less commonly used are SHARED and LEAP) auth_alg=OPEN }
When you’re done editing the file, press CTRL+X to save and exit the document. Now is the time to unplug the Ethernet cable and plug in the Wi-Fi dongle.
At the command prompt, enter the following command:
sudo reboot
When the device finishes rebooting, it should automatically connect to the Wi-Fi node. If for some reason it fails to appear on the network, you can always plug the Ethernet cable back in to double check the two files and the variables you altered.

Add the following section to your advancedsettings.xml and then tweak them as explained later in this post.
<advancedsettings> <network> <buffermode>0</buffermode> <!-- Comment: Default is 1 --> <cachemembuffersize>20971520</cachemembuffersize> <!-- Comment: Default is 20971520 bytes or 20 MB --> <readbufferfactor>1.0</readbufferfactor> <!-- Comment: Default is 1.0 --> </network> </advancedsettings>
Note that these presets may differ with distro you use and some of the tweaks may not work on XBMC 12.X Frodo and below.
Works on XBMC 13 Gotham and above. The buffermode sets what videos XBMC will cache. The default is 0, which will cache all videos from the internet (http, FTP, WebDAV, etc.). Listed below are other options:
1 Buffer all videos, including local videos 2 Buffer only true internet streams (http, strm, etc.) 3 No buffer
If you experience XBMC stuttering while playing videos from your local network storage, then choose 1 as Buffermode. Playing from a USB drive or SD card should almost never cause XBMC buffering issues unless there is some hardware compatibility issue. cachemembuffersize
By default XBMC allocates 20 MB for cache (note that in reality this is require 3 times more free RAM, 60 MB in this case). If you choose to cache videos, then increasing the available cache memory may help. On Raspberry Pi, with OpenELEC, Xbian or Raspbmc, I would not go beyond 40 or 50 MB (note that this requires 120 or 150 MB of free RAM) or else XBMC might crash frequently. To set cachemembuffersize to say 40 MB use 41943040 (40 x 1024 x 1024). If you are on a full-blown HTPC with say 4 GB RAM, you could go higher.
Alternatively, you could set the cachemembuffersize to 0, which would force XBMC to use your local storage (SD Card) for caching videos. In this case, the cache size is only limited by the amount of free space available. Upon stopping the video the cache is automatically cleared to free up space. Note that this will increase the read/write on your SD card, which may reduce its lifespan. But SD cards are cheap and doing this can help low RAM devices such as Raspberry Pi. But a good SD card with higher class rating is definitely recommended. [Read: 10 Tweaks to improve XBMC performance on Raspberry Pi]
Works on XBMC 13 Gotham and above. The default value is 1.0, which will make XBMC cache a little above what is needed to play it back. This setting affects how much of your network bandwidth is hogged to cache the video. In my home, while I am while I am watching a video, it take priority over anything else. So setting a 2.0, 3.0, or 4.0 will that many times higher bandwidth usage. In most cases setting it at 4.0 should not cause any issues. However, if you notice any spikes in CPU usage or network bandwidth unavailability for other devices then reduce the readbufferfactor.
The recommended entry in advancedsettings.xml file to reduce XBMC choppiness, stuttering, and buffering problems on Raspberry Pi is given below:
<advancedsettings> <network> <buffermode>1</buffermode> <!-- Comment: Default is 1 --> <cachemembuffersize>0</cachemembuffersize> <!-- Comment: Default is 20971520 bytes or 20 MB --> <readbufferfactor>4.0</readbufferfactor> <!-- Comment: Default is 1.0 --> </network> </advancedsettings>

User’s Guide » Installation on Raspberry Pi
You can install Kivy manually, or you can download and boot KivyPie on the Raspberry Pi. Both options are described below.
Note that Kivy has been tested with the original Raspberry Pi Model A/B. No guarantee is made that it will work on a Raspberry Pi 2. Manual installation¶
Add APT sources for Gstreamer 1.0 in /etc/apt/sources.list:
deb http://vontaene.de/raspbian-updates/ . main
Add APT key for vontaene.de:
gpg --recv-keys 0C667A3E gpg -a --export 0C667A3E | sudo apt-key add -
Install the dependencies:
sudo apt-get update
sudo apt-get install pkg-config libgl1-mesa-dev libgles2-mesa-dev \
python-pygame python-setuptools libgstreamer1.0-dev git-core \
gstreamer1.0-plugins-{bad,base,good,ugly} \
gstreamer1.0-{omx,alsa} python-dev
Install pip from source:
wget https://raw.github.com/pypa/pip/master/contrib/get-pip.py sudo python get-pip.py
Install Cython from sources (debian package are outdated):
sudo pip install cython
Clone and compile Kivy:
git clone https://github.com/kivy/kivy cd kivy
Build and use kivy inplace (best for development):
make echo "export PYTHONPATH=$(pwd):\$PYTHONPATH" >> ~/.profile source ~/.profile
Or install Kivy globally on your system:
python setup.py build sudo python setup.py install
KivyPie distribution¶
KivyPie is a compact and lightweight Raspbian based distribution that comes with Kivy installed and ready to run. It is the result of applying the manual installation steps described above, with a few more extra tools. You can download the image from http://kivypie.mitako.eu/kivy-download.html and boot it on a Raspberry PI. Running the demo¶
Go to your kivy/examples folder, you’ll have tons of demo you could try.
You could start the showcase:
cd kivy/examples/demo/showcase python main.py
3d monkey demo is also fun too see:
cd kivy/examples/3Drendering python main.py
Where to go ?¶
We made few games using GPIO / physical input we got during Pycon 2013: a button and a tilt. Checkout the https://github.com/kivy/piki. You will need to adapt the GPIO pin in the code.
A video to see what we were doing with it: http://www.youtube.com/watch?v=NVM09gaX6pQ
wget http://www.omattos.com/pifm.tar.gz tar xvzf pifm.tar.gz sudo ./pifm sound.wav 100.0 (1) # then turn off the raspberry # plug a USB audio device into the raspberryPi # power up sudo apt-get install alsa-utils lsusb (2) alsamixer (3) arecord -fS16_LE -r 22050 -Dplughw:1,0 - | sudo ./pifm - 100.1 22050
-
100.0 is the frequency
-
This will display information regarding attached USB devices.
-
You can adjust the volume of your microphone by this utility
Here are some desription
-
arecord: Program we are using to record audio.
-
-fS16_LE: Output 16-bit data. Needed this way for PiFM to read it.
-
-r 22050: This specifies sampling rate to output recording. 22,050 is a good balance for speed and quality.
-
-Dplughw:1,0: to see all of the audio devices connected.
-
sudo ./pifm - 100.1 22050: Here sudo for root access, ./pifm run the FM module at '100.1' Mhz to transmit and '22050' is the sampling rate of the input. If you did everything right, after you run the command you should be able to tune your radio to 100.1 Mhz and hear yourself talking through the mic!
Create a bash script in /etc/init.d
sudo nano /etc/init.d/autostartpifm.sh
and add the following lines
#!/bin/bash cd /home/pi arecord -fS16_LE -r 22050 -Dplughw:1,0 - | sudo ./pifm - 100.1 22050
Make script executable and test
sudo chmod 755 /etc/init.d/autostartpifm.sh sudo update-rc.d autostartpifm.sh defaults (1) sudo /etc/init.d/autostartpifm.sh start (2)

registering the script
-
Pressing CTRL+C to exit
To remove the script:
sudo update-rc.d -f autostartpifm.sh remove
