I am having great trouble trying to get a trace of my touch screen on Sharp Zaurus SL5600. It is running a Linux 2.4.18 with Qtopia. I know this might not be the perfect place to ask but I really need some help.
All I want to do is to record the touch screen events (by catting /dev/ts to a file) and meanwhile, send the events normally to the screen. After this, I want to play back the events I recorded. It is this simple, but when I tried with this:
# cat /dev/ts
# cat /dev/ts > fred
the system doesn't seem to be receiving any pen events, no matter what I click on the touch screen. Although I could see that there are unreadable outputs in the console (or in the fred file).
What shall I do to record the /dev/ts activity without stop the touch screen from sending events?? And how do I play back??
Any thoughts will be hugely appreciated!!
