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-d
devname-f
filename-h-n-utpctl won't
do calibration if the database file already contains parameters for the
touch panel.-vYou 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.
-f flag may be used to specify an alternate
database file name. tpctl will create an empty
database file if it doesn't exist.-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.-d flag may be
used to specify an alternate touch panel device name.tpctl isn't available on all ports because it requires a
display device which provides the ‘hpcfb’ interface.
