DS1990 no reading using touch.c
PostPosted: Wed Sep 21, 2005 6:40 am     Reply with quote
Hi,
I am using 18F458 and picdem 2 plus.

B0 is connected to +5V through a 4.7k resistor, from probe one wire is connected to B0 and another wire is connected to Ground.

with Ex_touch.c, i only can see "Waiting for a touch device..." via hyperterminal. No result shown if iButton touch the probe.


Can anyone help?

Thanks.
Mark

And exactly why are you double posting? Here is some code that might help
Code:

  while ( Read_Forum_Policy() == FALSE);
  while ( Follow_Forum_Policy() == FALSE);
  if ( Double_Post( WITHIN_1HOUR_14_MINS) == TRUE )
   Get_No_Help_From_Mark();
  else
    Mark_Will_Help();
