Use a Wii Remote as a slide clicker.

This application also serves as an example for using the Rust bindings to the xwiimote user-space library.

You will need the following dependencies to build and use wiinote:

• Rust >= 1.61
• libudev >= 183
• libxwiimote >= 2-2 (optional; set XWIIMOTE_SYS_STATIC=1 to build from source and link statically.)
• libdbus-1-dev >= 1.12.20

Enable the uinput kernel module, which lets us create a virtual keyboard device and emit key events corresponding to button presses on a Wii Remote:

modprobe uinput

Enable the Wii Remote kernel driver, which is used to communicate with a Wii Remote and its extensions (such as a Nunchuck):

modprobe hid-wiimote

Pair and connect to a Wii Remote as with any other Bluetooth device; see the ArchWiki article for details.

Allow the current user to access the /dev/uinput device file:

groupadd -f uinput
gpasswd -a $USER uinput
cat >/etc/udev/rules.d/40-input.rules <<EOL
KERNEL=="uinput", SUBSYSTEM=="misc", GROUP="uinput", MODE="0660"
EOL

Reload the udev rules:

udevadm control --reload-rules && udevadm trigger

Finally, run the application with ./wiinote. By default the program exits if no connected Wii Remote is found, but this behavior can be changed via the --discover flag. The output of ./wiinote --help contains further information on automatic device discovery.
