thanks for replying so quick, i worked out how to use the timers today, thats not really what iam looking for but its a start, what i really wanted was to use a tmmer that i can initiate just before a loop , that runs in the background, so as not to consume any processor speed and when it times out it can jump to a label, i am thinking i may be able to do it with the WDT i will have to experment. i have no code as yet just this idear and urge to work it out, again thanks for any hlp you can give me, and your quick responce thankyy
