    Pulse Width Measurement

    Anyone know code for measuring a pulse from a 555 timer?
    Any help would be much appreciated?
    Below is the code i have at the minute

    #include <16f874.h>
    #use delay (clock = 4000000)
    #byte PORTC = 7
    #bit INPUT = PORTC.0
    setup_timer_1(T1_INTERNAL , T1_DIV_BY_1);
    long int PERIOD;
    set_tris_c (0x01); // setting up ports
    PERIOD= 0;

    PERIOD = get_timer1();

    Look up "Capture" in the Datasheet.
    7. It is easier to write an incorrect program than understand a correct one.
    40. There are two ways to write error-free programs; only the third one works.*
