1Wire interface

Is there sombebody was trying to make 1wire implementation?

http://www.friendlyarm.net/forum/topic/1580

work ok for me,
the only "problem" is that the mini2440 gpio is possible only 3,3V and not
5v tolerant.

if you are goinig to work with long cables, and use the 5V pin,
you can´t work with pullup resistors on the gpio pin.

i got a dalles sensor on a 35m cat5 cable,
and 3,3v with pullup don´t work.

or 2x 4m cat5 cable with 2 and 3 sensors also don´t work reliable with 3,3V
and 4k7 or 2,2k pullups.

a support question if any gpio pins are 5v toerant have been dropt at
samsung, still waiting for a answer.

now time for development, but will most probably make 1wire through
UART/RS232

good night

anyone knows the 1 wire management protocol to wince, to measure the
temperature of a sensor, DS1820.

Thank you very much ..
