I want to learn TIMER for pic16f877a in HTC.can anyone teacn me?I duno how to use it.
http://www.microcontrollerboard.com/pic-timer0-tutorial.html

i try to learn from this website but it seem like not really clear because i hv seen from other website they will calculate in other method.confusing me!
i just want to know timer for pic16f877a and how we going to use it in a better way and the calculation method.


thank you^^

That is a pretty good website, It is the one of the ones I used to learn how to use timers. I am not sure what we can well you that the website does not. Maybe is you had specific questions?

You might also try this site

Another excellent site.

I can tell you from personal experience that the MOST IMPORTANT thing you need when learning how to use timers (and various other things) is the processor's datasheet. It's easy enough to find--just google PIC16F877A, select the Microchip link, and open the datasheet. Trust me, you WILL NOT understand timers unless you read about the module on the datasheet. Once you read that, if you still have questions, we can help you then.

It might help to mention which calculations and exactly where they can be found on each page. If you expect people to help you then you need to put some effort into helping them to help you.
@spinnaker

Sorry i thought that the link i gave will direct you to the calculation part.When you click into the link the calculation part is actually at the Description tab.

You know you really need to have a scientific calculator coupled with some basic exp knowledge too.

Some of these formulas are bordering on complex calculus types.

Can you transpose boolean algebra equations?

@T.Jackson

Ya i know boolean algebra.you mean the calculation using 0 and 1?

No. I mean more so algebraic transpositions sorry.

Like: c = a x b
Therefore b = ?

Or ...

a / b = c / d
a x d = b x c

Therefore a = ?
b = ?
c = ?
d = ?

If you cannot do this, then you cannot work with the timer on a pic properly.

What a load of rubbish!
PIC timer calculations only involve simple algebra, they involve absolutely no calculus nor any Boolean algebra. If you can transpose a simple equation you can do the timer calculations.
A simple calculator does speed things up but is not essential as the arithmetic is pretty basic and can easily done with a pencil and paper.

For reasonable tutorials on PIC timers take a look at lessons 9 and 10 at http://www.gooligum.com.au/tut_midrange_C.html
