    You are correct!

    You can only get 2 PWM's from it.

    The ECCP does have several outputs. But, they can not be configured to output different frequencies or PWM dutycycles.

    If you want more PWM's have a look at the 18F2431 - sports up to 4 PWM's with complimentary outputs...

    Now that's a Cool chip.

    I can't believe I haven't seen it before.

    Wow, all those PWM's, and Capture channels.
    Built in Quadrature Encoder Interface.
    Super Fast A/D.

    And everything else a good 18F would have.

    Geez, where have I been..

    Thanks fanie!

    I have to agree it's a nice PIC even if it's hundred times too big for a so simple task.

    Sorry to be a pest but, the Darrel's Link or the interrupt based routine is still the cheapest solution and will learn you something.

    It's not a bug, it's a random feature.
    There's no problem, only learning opportunities.
