hitachi - driver for Hitachi HDG-J series tablets
Streams module name: hitachi
X name: hitachi
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
information.
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.
VALUATORS AND BUTTONS [Toc] [Back] 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
stylus.
DEVICE CONTROLS AND QUERIES
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:

HITACHI(7) HITACHI(7)
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.
