Hi There,

 Is there any universel equation that i can use to get the right
prescalar that i need and the right number that i should put into the
TMR0 so that it can get the right timing ???

 Thanks
R.C.


 Hi,
Yes I saw it on the Myke Predko's book.
There are two way to get it...
 If you want the delay..

 Delay = (256 - InitTMR0 * prescaler)
             -----------------------------------------
                     Frequency / 4

 Or if you want the value to put in TMR0 to get a determinate DELAY

 InitTMR0 = 256 - ( DELAY * Frequency ) / ( 4* Prescaler)
Ah! DELAY in seconds

 I hope that I could help you

 Regards
 Luis F
