NAME

tpctltouch panel calibration utility

SYNOPSIS

tpctl [-D dispdevname] [-d devname] [-f filename] [-hnuv]

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.
