Ok i i flipped the wires on the ds1820 around (PIN1=3 PIN2=2 PIN3=1)
And now get

Done =1 FAM=$FF
Power=VDD

When i put a 10K pullup resistor on i get

Done =1 FAM=$10
Power=Parasite

when i take the resistor away i get

Done =0 FAM=$00
Power=Parasite

I flipped the ic around and get these readings

When i put a 10K pullup resistor on i get

Done =1 FAM=$FF
Power=VDD

when i take the resistor away i get

Done =1 FAM=$FF
Power=VDD

Does anyone have these problems?
