Hi Waqar,

Its like I need 60,000 Dollars. Government of USA does not print a bill of this amount so I can't buy anything of ten thousand dollars :(

But I got an idea:

why not add 600 bills of 100 $ each and make total amount that I need :)

was a joke, but good enough to make you understand that any amount is made up of some basic units.

use a value of #100d in autoreload mode (with 12MHz) and increment a counter 10 times in an ISR. That will give you a delay of 1Sec. (some software tuning would yet be required to cut off the overhead for the time taken by instructions themselves).

Increment another counter above 60 times and that will give you a delay of 1 min.

Good Luck

Babar


PS:
Never implement the delays (particularly in clocks) in the delay loops like DJNZ.....

How can you do other stuff like refreshing the display or allow time setting with the loop. Even if you can do that withing the loop it will screw the accuracy of the clock until you take care of time by every instructin being executed and make adjustments therein the code and eventually blow your mind.
