Startup
Remotely: provide DHCP over Ethernet
Access via ssh, Username: pi Password: raspberry
First time, the device propose to run raspi-config
sudo raspi-config
Then, better to renew SSH server keys, see RPi remote access
sudo rm /etc/ssh/ssh_host_* && sudo dpkg-reconfigure openssh-server
Wi-Fi
Using Wi-Pi
See user manual for Raspbian.
Edit /etc/network/interfaces and add wlan0 section similar to:
auto wlan0 iface wlan0 inet dhcp wpa-ssid <name of your WiFi network> wpa-psk <password of your WiFi network>
Then
sudo /etc/init.d/networking restart
NFC
apt-get install git autoconf libtool gcc libusb-dev apt-get install dpkg-dev debhelper dh-autoreconf git clone https://code.google.com/p/libnfc/ cd libnfc dpkg-buildpackage -b -uc -us cd .. dpkg -i *deb
For a SCL3711:
modprobe -r pn533 echo blacklist pn533 > /etc/modprobe.d/pn533-blacklist.conf
SPI
sudo modprobe spi_bcm2708
Test:
wget "http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=blob_plain;f=Documentation/spi/spidev_test.c" -O spidev_test.c gcc -o spidev_test spidev_test.c sudo ./spidev_test
We should get some hex dump about dead beef and bad food ;-)
If test fails, see here for updating stuffs:
GPIO pinout, see also here
With Python:
