    Ioannis,

    Thanks for the feedback!

    I have been using the attached calculator from Mister E.

    Name: Mr_E.png Views: 705 Size: 8.3 KB



    Is the Duty Step % (0.625) X 50% = 31.25% the problem?
    (I am measuring 3.8uS On / 4.2uS Off)
    How can I set it for 4mS On / 4mS exactly?

    (FYI, I am headed towards filtering the Square wave into a Sine wave and want it to be symetrical.)

    Is this even doable with the ancient 16F628?
    I am only using this because I had the Dev Boards handy.
    Do you remember Bruce Reynolds?
    What would you recommend for a 8PIN Dip?

    Peace,

    Jay Zebryk
