Sub Timer1_Tick
..../...
-> Too much done here for an interrupt, see my comment below
And :
onewire.Reset
onewire.Select(address)
onewire.Write(0x44, True)
'give it 1 second to read the temperature <- oh OK, but it's not done afterwards in the function, while the same commands are used again...
CallSubPlus("ReadTemparature", 1000, 0)
End

Private Sub ReadTemparature (u As Byte)
onewire.Reset
onewire.Select(address)
etc.
