Special feature of piControl:
All services mentioned above with the exception of piControl are so-called daemons, which are processes running in the background. piControl is a kernel driver. Under Wheezy it can be activated or deactivated with the commands above. Under Jessie the procedure is different, edit the file /etc/modules (“sudo nano /etc/modules”) and comment out the line with “piControl”. Both Wheezy and Jessie must then restart the Revolution Pi.
