Hi, i´m new in the forum,
i´m designing a program to simulate a Dallas 2401 (1Wire),
but all routines i´ve seen here are MASTER ROUTINES,
and I need to simulate one DS1990A routines (SLAVE)
I need some routine or help to be a 1-wire device!

For details, i´m programming in C, i have a 5K pull-up, i´m polling signals ok.
So i write a program like this but, i have some electrical problems i think,
because the master doesn´t recognize me.

When i write a "Zero": i detect the flank THEN write a zero for 45usec, but appears some noise when the "one" time slot ends (7usec).

THANKS A LOT!
