Connections SPI (logiciel) :

On peut se brancher sur n'importe quel GPIO du moment que le script python ensuite les prenne en compte.
On peut brancher le dispositif a chaud sur le raspberry pi.

sudo apt-get update
sudo apt-get install build-essential python-pip python-dev python-smbus git
sudo pip3 install python-osc
