[PATCH v2 3/3] Add sixaxis plugin: USB pairing and LEDs settings

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Add a plugin which handles the connection of a Sixaxis device, when a
new hidraw device is connected the plugin:
 - Filters udev events, and select the Sixaxis device
 - Sets LEDs to match the joystick system number (for USB and BT)
 - Sets the Master bluetooth address in the Sixaxis (USB pairing)
 - Adds the device to the database of the current default
   adapter (BT association)

Changes since previous version:
 - Use 'sixaxis' as plugin name because this is not a generic cable pairing
   mechanism.
 - Drop dependency on libusb, we can now use hidraw to send feature reports,
   since this patch has been accepted:
   https://patchwork.kernel.org/patch/485671/
 - Other autotools cleanups (use UDEV_LIBS, check for the needed hidraw
   ioctls)
 - Rebase on latest bluez (s/debug/DBG/, use adapter_get_device(), etc.)
 - Misc fixes: change indentation, reorder includes and functions, etc.
 - Add support for setting LEDs according to the joystick system number.
 - Address some of Marcel's comments from the previous submission:
   http://marc.info/?l=linux-bluetooth&m=125525415718147&w=2
   + Use hidraw
   + separate check for UDEV in the autotools changes

A description of the udev part of the plugin can be found here:
