I'm using two timers of Pic18 family controller. The Timer 1 is used for RTCC and Timer 2 is used for counting minutes.
I have used a crystal for RTCC feature, and for Timer 2 I have fixed a count'x' and if count 'x' is equaled, then a minute have been surpassed.
And I would like to make a design such that when Timer 2 counts to 60 mins, do task 1.
My question is: Even though the two timers are of the same controller, will there be any lag (delay in secs) between both timers which would result in any possible delay (in sec or minute)?
Is there any delay possible, I trust there will be delay, but how much is my question. Will it integrate over time?
I would like to know more from people who have used this feature and in course of time if they have experienced any delay or so? And I would welcome any valuable suggestions too.
