Frequency Counter using Interrupts PIC18f4580 Project

Frequency Counter  using PIC18f458 0 Proje ct This POST describes the construction of small frequency counter with a cheap PIC18f4580 microcontroller with 16 x 2 LCD.   Prerequisites: PIC18F4580 TIMER Programming. PIC18F4580 COUNTER Programming. PIC18F4580 Interfacing with 16x2 LCD. PIC18F4580 Interrupts Programming  ( we will cover in this POST) Concept: Frequency  is the number of occurrences of a repeating event per unit time. in our case we will measure a number of clocks generated by clock source per unit time. In this project, LCD is used to display the frequency and PIC timer 1 to measure the input signal and Timer0 to generate an indication that one second has gone. System software utilizes Timer-1 in the 16-bit counter mode to count the input signal and overflows of the counter are added to provide the aggregate count in multiples of 65536. Totaling the existing value of the counter at the conclusion provides...
