Relate EBD9312 touch driver & fb driver

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi all,

Thanks for ur support in the fb driver issue on the EDB9312 type board.
I have worked on the fb driver and figured it out. I am working on the
touch driver right now. Touch driver does work, but calibration problem
persists.

My relevant device specifications:-

EDB9312 running 
	Frame Buffer driver
	Touch driver
There is NO X11 on the Device running. I am testing the touch driver
through Qt/Embedded Applications.

I am getting the interrupt, but the problem is I am unable to get the
correlation between the display driver, mouse click and the touch
driver.

I don't know the reason. I think we need to run calibration program. How
do I produce the appropriate X, Y, values?  I think the values of Z1, Z2
are appropriate as I am seeing the valid values.

Is the Calibration program a must to handle this? Can't we handle this
in the driver level?

Can some one briefly explain me how the touch driver communicates with
the display driver? I have registered my touch driver through
misc_register() call.

Regards,
Mukund jampala
