Touch Panel Calibration
I have an Arm based board with Touch Panel (st1232-touchscreen) running Debian 6.
I am trying to configure the touch panel with Xorg server.
For that I added InputDevice section in xorg.conf file and pointed it to use "evdev" driver. The touch panel started using xorg server but I am facing problems in calibration.T he mouse pointer is not in sync with touch. I tried following options but no luck.
(1). Using xinput_calibrator doesn't detect any touch and application terminates after timeout.
(2). evtest detects touch and prints correct co-ordinates. When I include those X Y co-ordinates in xorg.conf file, the mouse pointer disappers upon touching it.
(3). Running xinput test and touching panel prints values as below. a and a always remain zero.
a = 0, a = 0, a=256
a = 0, a = 0, a=248
a = 0, a = 0, a=269
I tried with tslib also but tslib is not able to detect the touch panel.
