I write code for counting captured pulse for every 1sec. compiler I used was MPLABIDE v8.92 and wrote my source code in hitechC, controller used was pic16f877a.
problem in my code is every 10 count missed 1 count that means I set frequency as 100Hz output shows in display is 91. I attached my code and simulation clip please suggest solution for this problem.

Hi, i dont have mplab at the moment to test the code. have you tried to simulate it in mplab? check if the trigger works properly, and also on different frequencies.
