Installation de la raspberry Pi

Utilisation du version minimaliste de raspbian

Nous avons choisis une version minimaliste de raspbian disponnible ici : http://www.linuxsystems.it/raspbian-wheezy-armhf-raspberry-pi-minimal-image/

Pour préparer la carte SD suivre le tuto ici (section command line interface) : http://www.raspberrypi.org/documentation/installation/installing-images/linux.md

Création du point d'accès wifi

Note pour la clé wifi Brest-wirless faut installer :
sudo apt-get install zd1211-firmware

Installer le nécessaire pour avoir du wifi :

apt-get install wireless-tools wpasupplicant

apt-get install hostapd udhcpd

Notre fichier /etc/udhcpd.conf :

# Sample udhcpd configuration file (/etc/udhcpd.conf)

# The start and end of the IP lease block

start		192.168.42.100	#default: 192.168.0.20
end		192.168.42.150	#default: 192.168.0.254


# The interface that udhcpd will use

interface	wlan0		#default: eth0


# The maximim number of leases (includes addressesd reserved
# by OFFER's, DECLINE's, and ARP conficts

#max_leases	254		#default: 254


# If remaining is true (default), udhcpd will store the time
# remaining for each lease in the udhcpd leases file. This is
# for embedded systems that cannot keep time between reboots.
# If you set remaining to no, the absolute time that the lease
# expires at will be stored in the dhcpd.leases file.

remaining	yes		#default: yes


# The time period at which udhcpd will write out a dhcpd.leases
# file. If this is 0, udhcpd will never automatically write a
# lease file. (specified in seconds)

#auto_time	7200		#default: 7200 (2 hours)


# The amount of time that an IP will be reserved (leased) for if a
# DHCP decline message is received (seconds).

#decline_time	3600		#default: 3600 (1 hour)


# The amount of time that an IP will be reserved (leased) for if an
# ARP conflct occurs. (seconds

#conflict_time	3600		#default: 3600 (1 hour)


# How long an offered address is reserved (leased) in seconds

#offer_time	60		#default: 60 (1 minute)

# If a lease to be given is below this value, the full lease time is
# instead used (seconds).

#min_lease	60		#defult: 60


# The location of the leases file

#lease_file	/var/lib/misc/udhcpd.leases	#defualt: /var/lib/misc/udhcpd.leases

# The location of the pid file
#pidfile	/var/run/udhcpd.pid	#default: /var/run/udhcpd.pid

# Everytime udhcpd writes a leases file, the below script will be called.
# Useful for writing the lease file to flash every few hours.

#notify_file				#default: (no script)

#notify_file	dumpleases	# <--- useful for debugging

# The following are bootp specific options, setable by udhcpd.

#siaddr		192.168.0.22		#default: 0.0.0.0

#sname		zorak			#default: (none)

#boot_file	/var/nfs_root		#default: (none)

# The remainer of options are DHCP options and can be specifed with the
# keyword 'opt' or 'option'. If an option can take multiple items, such
# as the dns option, they can be listed on the same line, or multiple
# lines. The only option with a default is 'lease'.

apt-get install python3.2

Bluetooth (pour la montre liveview)

Installation du bluetooth :

apt-get install bluetooth

Démarrer la montre en restant appuyer sur les 2 boutons.

Faire un scan bluetooth :

pi@raspberry-pi:~$ hcitool scan
Scanning ...
BC:85:56:68:92:8E	ubuntu-0
30:39:26:C4:B0:C2	LiveView
Voir ce qu'il manque pour l'apairage

I2C (boussoles, accéléro ...)

apt-get install python-smbus python3-serial

Ajouter en fin du ~/.bashrc :

export QUICK2WIRE_API_HOME=/home/pi/OpenPathView_wip/includes/quick2wire-python-api
export PYTHONPATH=$PYTHONPATH:$QUICK2WIRE_API_HOME

Puis faire un :

source .bashrc

Permissions, editer le fichier /lib/udev/rules.d/60-i2c-tools.rules :

KERNEL=="i2c-[0-9]*", GROUP="i2c", MODE="0666"
