 +=== Or install pdwiringPi ====

 +An other wiringPi external is that one [[https://github.com/garthz/pdwiringPi]] by Garth Zeglin. It also support PWM over GPIO for the pins: 12, 13, 18, 19.\\
 +   $ wget https://github.com/garthz/pdwiringPi/archive/master.zip
 +   $ unzip master.zip
 +   $ cd pdwiringPi-master
 +   $ make
 +There should be a new folder called "pdwiringPi". Add that one the Pure Data -> Preferences -> Path.\\
