WIIMOTE LINUX DRIVER INSTALLATION INSTRUCTIONS

Installing the Driver

 Before you install this driver, there are a few things you need to have ready:

	1) bluez should be installed on your system. If not, check out 
	   http://www.bluez.org

	2) A bluetooth adapter (internal or external).
	
	3) a Wii remote.

 If you have everything listed above, then all you need to do is:
	
	1) Execute the 'make' command within the wii_source directory
		
		i.e. wii_source$ make
	
	2) Execute the start.sh script. You'll need root access since the
	   start.sh script inserts a new driver module into your kernel. You can	   use sudo to execute start.sh like so:

		wii_source$ sudo ./start.sh

	   Once the shell prompt returns, take your wii remote and press the
	   number 1 and 2 button at the same time. The blue lights on your wii
	   remote will start flashing and the driver will attemp to establish
	   a connection with the wiimote. If a connection has been established,
	   you'll see a message in your shell that says 'data: 22, len = 5'.

USING YOUR WII REMOTE

 When your Wii remote has been connected, here's what you can do:

	1) Tilt the Wii remote up to move the mouse up
	
	2) Tilt the Wii remote down to move the mouse down

	3) Twist the Wii remote left to move the mouse left

	4) Twist the Wii remote right to move the mouse right

	5) Press the A button to left click

	6) Press the B button to right click

	7) Press the up directional button to scroll up

	8) Press the down directional button to scroll down 

STOPPING AND UNINSTALLING THE WII REMOTE

 To stop your mouse from being controlled by the wii remote, execute the stop.sh script. You'll need root access to execute this script, so you could try:

	wii_source$ sudo ./stop.sh

If you want to remove the Wiimote Linux driver from your computer, execute the
'make clean' command in your shell prompt (i.e. wii_source$ make clean)

TROUBLESHOOTING

 If you run into trouble installing or using the Wii remote, here are a few 
problems we ran into that might help you out:

	1) The Wiimote Linux Driver won't compile

		- This most likely means that bluez is not installed on your
		  system. You can check out http://www.bluez.org for the
		  packages needed to get bluez onto your system.

		- The other possibility is the symbolic link 'build' in your
		  /lib/modules/<your kernel version here> isn't pointing to 
		  the correct linux headers directory. For instance, the 'build'		  link on my system looks like:

			build -> /usr/src/linux-headers-2.6.20-16-generic

		  If you're thinking of changing what your 'build' file points
		  to, make sure it's not already pointing to a directory with
		  the ls -l command. If 'build' is pointing to another 
		  directory, make sure to at least record the directory before 
		  changing 'build'.

		  You can change your 'build' file to point to your headers
		  directory with the command:

			ln -s -f -T <header files directory> build

	2) The Wii remote doesn't move the mouse

		- We found during testing that the connection between the Wii
		  remote and a bluetooth adapter is not always clean. This
		  driver doesn't attempt to recover lost data packets, so you
		  might see some lag when using your wii remote.

	3) My computer really slows down when I use the wii remote

		- This is the one compromise we had to make when developing
		  this driver. Time suddenly got really short and we needed a
		  working product, so we decided to create a background daemon
		  process that continuously polls the wii remote for new data.
		  Hopefully it won't slow down your system too much, but any
		  lag you might notice is probably due to this desigh decision.
