about touch panel

[salih_yavuz]

hello everybody,

I want to ask something about touch panel and glcd and I hope that someone can help me...

I'm designing a project with glcd and touch panel and I draw 4 buttons in the glcd and I want to determine those buttons at X and Y coordinate system. Therefore I'm using easypic v7 for determining those coordinates but I could not be successful.

You should say which 'touch panel' you're using.
From an 'overall design' though, you need a simple program to read the touch screen and display the X, Y values that it sends when the screen is touched.
Using graph paper you can 'see' what range of pixels would be 'valid' for a 'button' location,which should be 1 less than the drawing program pixels( inside the box outline).

Some screens are analog,some digital, some 'auto' report, some need polling, some interrupt driven,some 8 bit, 12 bit, 16 bit,etc.
Without knowing what panel you have, I can't help further.
