Re: Trying to count from 2 counters Timer 0 and Timer 1

Thankyou for all your help and clear guidance.
I first tried working without an interupt and it worked the same as before
Then i created an interupt to handle timer1 where i load it with FFFE and add to my pulse count on over flow and it works.
I will probably do the same for timer 0

Thank you again.

Re: Trying to count from 2 counters Timer 0 and Timer 1
