SYNOPSIS

DESCRIPTION

     palmax is an XFree86 input driver for the Palmax
     PD1000/PD1100

     The palmax driver functions as a pointer input device, and
     is normally used as the X server's core pointer. It supports
     positioning and mouse buttons using the touchscreen display
     and lid buttons on the Palmax machines.

SUPPORTED HARDWARE

     Palmax PD1000, Palmax PD1100. In theory also any other sys-
     tem using a TR88L803 wired to a serial port.

CONFIGURATION DETAILS

     Please refer to XF86Config(5) for general configuration
     details and for options that can be used with all input
     drivers.  This section only covers configuration details
     specific to this driver.

     The following driver options are supported

     Option "MinX" "integer"
          Set the left hand X value from the touchscreen, for
          calibration.

     Option "MaxX" "integer"
          Set the right hand X value from the touchscreen, for
          calibration.

     Option "MinY" "integer"
          Set the top Y value from the touchscreen, for calibra-
          tion.

     Option "MaxY" "integer"
          Set the bottom Y value from the touchscreen, for cali-
          bration.

     Option "Screen" "integer"
          The screen to attach to the touchscreen when running
          with multiple screens. The default is screen 0.

     Option "Device" "string"
          The serial port that is attached to the touchscreen
          interface. On the Palmax PD1000 and PD1100 this is
          ttyS0.

     Option "DeviceName" "string"
          Set the X11 device name for the touchscreen. This
          defaults to TOUCHSCREEN.

     Option "PortraitMode" "string"
          Set the display orientation. The default is "landscape"
          but you can rotate the screen clockwise ("portrait") or
          anticlockwise ("portraitCCW").

     Option "SwapXY" "boolean"
          Swap the X and Y values on the display. The default is
          false.

     Option "TapButton" "boolean"
          Set the touchscreen tap to act as mouse button 1. This
          allows single handed operation except when using the
          menu buttons. The default is false.

BUGS

     The driver has been tested on the Palmax systems, the
     defaults reflect the Palmax hardware and should work out of
     the box. No testing has been done on other systems using the
     same digitizer.

     Support for a double-tap menu button option would be nice.

     The smoothing algorithm would benefit from real mathematics.

     XFree86 needs a nice calibration tool.
