HITACHI(7)							    HITACHI(7)

NAME    [Toc]    [Back]

     hitachi - driver for Hitachi HDG-J	series tablets

SYNOPSIS    [Toc]    [Back]

     Streams module name: hitachi
     X name: hitachi

DESCRIPTION    [Toc]    [Back]

     This driver is for	the Hitachi HDG-J series of tablets. It	will probably
     also work on other	hitachi	tablets	capable	of running in Hitachi III
     mode. It operates the tablets in high-resolution mode to provide for
     smooth drawing. These tablets provide x, y, height, pressure and tilt

     The driver	uses hitachi as	the X name of the device. (See input(7).)

     The difference between this drive and the driver called tablet, which is
     also for Hitachi tablets, is the use of high-resolution operation and
     Hitachi III mode.


     The hitachi driver	supports 6 valuators and 4 buttons. The	valuators are
     x,	y, pressure, height, x-tilt and	y-tilt.	The order just given is	the
     ordering of the mapping to	X extension valuators. That is,	pressure is
     extension valuator	2, etc.

     The tablet	is available with either a four-button puck or a two button

     The hitachi driver	supports the following controls	and matching queries:

     btnpressure <pressure>
	  This control specifies the threshold above which the tip pressure
	  generates a button event.  Note that this is a raw 8 bit integer,
	  *not*	an ascii decimal number.  To set the tip button	pressure to
	  '5', use '^E'	(control-E), NOT '5'.  This option controls the
	  mapping of physical pressure events on to X button events, but it
	  does not affect the observed characteristics of the device. This
	  control only takes effect when the pressure control is on.

     pressure on/off
	  This control turns on	and off	the reporting of pressure, height and
	  tilt information.  This option adds axes to a	device,	so it should
	  be a device_init option.

     scale[xXyY0-5] <scale factor>
	  Control scaling on an	axis by	axis basis.  To	use this, first	set
	  scalewhich none in the X server so the X server doesn't clobber your
	  values.  For example:

	  scalex "1/5"
	       scales core pointer x events by one fifth.

	  scale4 "5"
	       scales extension	valuator 4 (x-tilt) events by 5.

	  Note that changing scaling does not affect the range of the valuator
	  - extension valuators	are clamped to the range of the	device.	  In
	  other	words, if you scale a tablet axis by 5,	you'll only be able to
	  use one-fifth	of the tablets surface in the corresponding direction.
	  These	affect mapping only, so	they can

     In	addition the control btnmap is recognized but is not implemented.
