/*
* Driver to use Handykey's Twiddler (the first edition, i.e. the one with
* the RS232 interface) as a joystick under Linux
*
* The Twiddler is a one-handed chording keyboard featuring twelve buttons on
* the front, six buttons on the top, and a built-in tilt sensor. The buttons
* on the front, which are grouped as four rows of three buttons, are pressed
* by the four fingers (this implies only one button per row can be held down
* at the same time) and the buttons on the top are for the thumb. The tilt
* sensor delivers X and Y axis data depending on how the Twiddler is held.
* Additional information can be found at http://www.handykey.com.
*
* This driver does not use the Twiddler for its intended purpose, i.e. as
* a chording keyboard, but as a joystick: pressing and releasing a button
* immediately sends a corresponding button event, and tilting it generates
* corresponding ABS_X and ABS_Y events. This turns the Twiddler into a game
* controller with amazing 18 buttons :-)
*
* Note: The Twiddler2 (the successor of the Twiddler that connects directly
* to the PS/2 keyboard and mouse ports) is NOT supported by this driver!
*
* For questions or feedback regarding this driver module please contact:
* Arndt Schoenewald <arndt@quelltext.com>
