Wii remote
There are numerous ways to achieve control of the N900 using a wii remote. Please have a look at this thread
The method described here uses cwiid and wminput. This method is an expansion on the instructions provided here by the user thp, who re-packaged cwiid.
change to root (by whichever method you chose)
root
install cwiid-utils from extras-devel.
apt-get install cwiid-utils
if not already installed install python-cwiid
apt-get install python-cwiid
Then execute the following two commands
modprobe uinput
chmod a+rw /dev/input/uinput
Then create a config file. The file below is for controlling the inbuilt media player
Wiimote.Left = KEY_LEFT Wiimote.Right = KEY_RIGHT Wiimote.A = KEY_SPACE Wiimote.B = KEY_SPACE Wiimote.Minus = KEY_F7 Wiimote.Plus = KEY_F8
The code was saved in /home/user/.cwiid/wminput/mediaplayer
This is one of the places that gets searched by wminput as detailed here
Once saved ensure bluetooth is on and simply execute:
wminput -c mediaplayer
from the command line. then press the 1 and 2 buttons on thhe wii remote and the command line should say ready after a little while. Once done simply start the media player. Once started simply use the wii remote buttons to control it. You can skip songs (forward and backward), pause/play and change volume.
