How to implement 15 minute timer? (PSoC 3/5)
The purpose is to monitor an incoming digital signal. If there hasn't been a high signal in 15 min then it should set an output pin to high.
We want a 15 min timer to be reset if a digital input Pin is high. If the timer reaches 0 then set a different digital Pin to high. This digital pin should be the input to some other logic (the reset on an SR latch)
Ideally we would take advantage of the sleep mode of the PSoC 3/5 as well.
Please comment with any ideas/solutions.
