touch panel calibration

SYNOPSIS
tpctl |
[-hnuv] [-D
dispdevname] [-d
devname] [-f
filename] |
DESCRIPTION
tpctl is a touch panel calibration utility.
tpctl calibrates a touch panel and saves and restores
the calibration parameters into/from a parameter database file.
Available command-line flags are:
-Ddispdevname- Specify display device name.
-ddevname- Specify touch panel device name.
-ffilename- Specify alternate parameter database file name.
-h- Print brief description.
-n- Do not change the parameter database file.
-u- Force calibration. Without this flag,
tpctlwon't do calibration if the database file already contains parameters for the touch panel. -v- Verbose mode.
You calibrate the touch panel the first time you run
tpctl. If you see a cross cursor on the screen, you
should tap the center of the cursor to calibrate the touch panel, or you can
abort the calibration with the ‘ESC’ key. Five cursors will
appear on the screen in turn. Once calibration is done,
tpctl saves the calibration parameters into the
database file and uses the saved parameters to calibrate the touch
panel.
You can run tpctl automatically with
/etc/rc.d/tpctl.
FILES
- /etc/tpctl.dat
- The default calibration parameter database file. The
-fflag may be used to specify an alternate database file name.tpctlwill create an empty database file if it doesn't exist. - /dev/ttyE0
- The default display device, which is used to display the cursor during
calibration. The
-Dflag may be used to specify an alternate display device name. The display device must provide the ‘hpcfb’ interface as defined in /usr/include/dev/hpc/hpcfbio.h. - /dev/wsmux0
- The default touch panel device. The
-dflag may be used to specify an alternate touch panel device name.

BUGS
tpctl isn't available on all ports because
it requires a display device which provides the ‘hpcfb’
interface.
