FT800 320X240 touch is not in sync

[kanlok]

Hi,

I am using FT800 320x240 display. All is working fine, however touch is not syncronized i.e if I am touchg at (x,y) 177,11. track touch is responding at position: 50,140.

I have set the display as per below code. Also, my code is below for reference.

Pls help.

Thanks,
Lokesh
