Controllers on the Raspberry Pi
Before we begin, you will want to install the joystick package to your device. Type
sudo
apt-get -y install joystick
at the command line and press
Enter
. The joystick
package includes an application called
jstest
, which will help you identify and
troubleshoot your controllers.
When a controller is connected and recognized by the Raspberry Pi, a new entry will be
made in the
/dev/input/
folder. This folder contains a list of all connected input
devices. You should see files like
event0
,
mouse0
, and
kb0
depending on what has
been connected. When your controller is connected, you should see a new item called
js0
.
The
0
at the end of the item indicates the order in which it was connected. You can have
multiple items connected, and they will each get an increasing number.
