tpctl —
touch panel calibration
utility
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:
- -D
dispdevname
- Specify display device name.
- -d
devname
- Specify touch panel device name.
- -f
filename
- Specify alternate parameter database file name.
- -h
- Print brief description.
- -n
- Do not change the parameter database file.
- -u
- Force calibration. Without this flag,
tpctl won'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
-f flag may be used to specify an alternate database
file name. tpctl will 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 -D flag 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 -d
flag 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.
