== Utiliser les broches digitale 13 et 14 ==
The cable to interconnect UniPi and RPi does not contain wires for inputs 13 and 14.
To get the inputs working you have to make a custom connection cable. Below is aed to picture of the P5 header on UniPi. It was design fit the RPi model B so it is the same as P5 header of RPi.

You can use any of the unused GPIOs and wire them to these two pins and of course edit the evok.conf file in order to make it work.

Les broches GND ne sont pas obligatoires et 3V3 est uniquement lorsque l'on utilise le second bus I2C.
