Hi Guys,

Thanks, interrupt on overflow sounds ideal.

FYI my event happens regularly with a max freq of 600 events per second and a min freq of 30 events per second. Depending on the time between events I have to calculate a time delay to generate an output event to occur within the time window of the time measured between the last two input events.

So if the time measured between input events is 0.8 seconds, I need to calculate a time which will always be < or = 0.8 seconds.

I'm measuring other process control variables so I'm trying to unload counting/timing tasks to hardware.

Thanks,

Wilson.
