25. Libraries
● Python
– Quick2wire, Rpi.GPIO
● C
– WiringPi, pihwm
● Bindings also available for Java(!), Ruby, Erlang
26. Tips for headless operation
● Use 240/16 (CPU/GPU) RAM split
– No need for graphical stuff
● Setup avahi/zeroconf
– No need to remember IP address
● ssh raspberrypi.local
● Setup mosh
– Great for intermittent networking
