    Joe

    Thank you!
    I used

    T1CON.0 = 0 'disable timer 1
    CCP1CON=0 ' disable capture compare module which works with timer 1

    and that solved my problem completely!

    After reading another thread I added
    LOW PORTC.0
    just before the loop and this seemed to solve my problem!
    Why would that be?
    Isn't TRISC %11111000 supposed to set PORTC.0 as an output?

    I forgot to say:
    The noise on PORTC.0 is present during the off pulse

    Noise on PORTC.0 with PIC16F73

    Hi All

    I am using a PIC16F73 and I am trying to pulse PORTC.0, PORTC.1 and PORTC.2
    I have set these ports as outputs using TRISC = %11111000
    However, when I measure the signal on the pins, the...

    Thank you for the suggestion.
    Is the purpose of the 4700uf on the 5 volt side to smooth out voltage spikes?
