counter program for pic16f877

hi ,
I wrote a timer interrupt program for PIC16F877 but i got confused for writing a counter mode program for PIC16F877 . anyone help me please...

mplab counter

i have written a program like making a pin high and low alternatively . i need to count number of times the pin goes high. For that any one help me please...

Probably the easiest is to use a pin with an interrupt capability on change (RB0/INT or RB4-7). In the interrupt routine simply increment your counter.

aandavan, could you post your code for review? maybe it would be useful...

also, in counter mode, wich timer are U using? have you changed to counter mode? are U using any interrupt in this counter mode?

 

[mg_designs]

use the timer to interrupt the program with
a known time u can calculate it from
delay = (max nu of counts - initial count )*time of one count
then an interrup routine will calculate the counts u count

 

[srinu249]

configure timer as counter mode .. then proceed

Hi!
If you post your code or describe the end use of the software more clearly then i will be in a better postion to help you. Are you using the controller to count something (items on a conveyor belt) and display the no of items?
