Thanks For link.
I found new driver implement for mini2440 "/dev/touchscreen-1wire"
so this 1 wire driver new implemented on kernel source.
So now i calibrate successfully but not Tocheffect from my qt application.
So What changed i need to do?

You have to make changes in ts.conf for that
change first line of ts.conf from 'module_raw input'
to "module _raw_one_wire_ts_input"

Hi Dipen,
Where did you find the 1-wire touchscreen driver ?
Can you share the link please ?

Thank you in advance.
