Jan-Erik,
     I am using a function that I pass a value to that represents the=20
number of seconds that I want the delay to last. I multiply this number=20
by ten in the for loop since there are 10 100ms interrupts for a second.=20
So if I pass 1 to the delay function, count will be tested for the=20
number 10. This is one second. If I call delay again and this time I=20
pass 15 to it, count will be tested for the number 150 and this is 15=20
seconds.
     Yes, I can use a while loop and I will rewrite it to do so as this=20
looks better but the for loop does the same thing. Now if I want to=20
change the delay based on the value of an ADC and controlled by the=20
position of a pot, I just have to correct the output of the ADC to=20
represent the position of the pot into something that the operator will=20
recognize as seconds. Then I just pass this number to the delay=20
function. So I can use the same function over and over rather than=20
calling two separate pieces of code. One that is hard wired for 1 second=20
and the other that can be controlled by the pot.
     But how do I reset the timer and where do I do this? Would I do it=20
before I call the delay function or inside the function just before I go=20
into the loop? Do I need anything more in the Interrupt routine than the=20
count variable?
Thanks,
rich!
