Touch Panel Calibration
Hi All,
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[0] and a[1] always remain zero. a[0] = 0, a[1] = 0, a[2]=256 a[0] = 0, a[1] = 0, a[2]=248 a[0] = 0, a[1] = 0, a[2]=269 I tried with tslib also but tslib is not able to detect the touch panel. Please help. Thanks. |
