Freq Out

I am working on a project and have been thinking about using a
Basic Stamp. I need have 8 pins putting out a wave form simultaneously,
each at a different pitch. Is this possible with the freqout command?
Is it possible with another method?

thanks

    Hi M,

    The FREQOUT command works on a single pin, sorry.
    You could however use thr DATA statement to define subsequent output states.
    Then rapidly output the values using OUTL=value (if you use ports P0-P7) or
    OUTH=value
    (if you use ports P8-P15). Be sure to define the used ports as outputs.
    Dependent on the required ratio for the wanted frequncies you have to figure
    out
    how many DATA values you require.
    Or use one of those PAK's from Al Williams. They can generate pulses
    independent from the stamp. http://www.al-williams.com/awce/pak8.htm

    Hope this helps

    Greetings peter

    The stamp will not do all 8 pins at once -- only one at a time. However, you
    *might* be able to do them in sequence for a very short period over and over
    to get a similar result.
