You schould find out the correct device file for your touch and the correct
amount of bytes for every touch event.
Try "cat /dev/touch > output" and check the file with hex editor.
Now you should be able to see, how many bytes per event are send..
Here is a example of my touch device...
#define TS_DEVICE_FILE "/dev/misc/tpanel"
struct ts_event {
long dummy;
short x;
short dummy2;
short y;
short pressure;
};
Bye
