I see this was already discussed a few years back, but I have the same issue and The only way I was able to reproduce what was in the book was by swapping out the 1u capacitor for a .01u. Is there a way to get it to work using the circuit designed in chapter 3? I tried every possible setting on the oscilloscope and was unable to get it to work.

    The most frequent cause of problems using scopes is setting up
    the proper trigger conditions.

    With the original circuit values installed, was the trigger mode set to
    AUTO? What was the vertical channel sensitivity?

    If possible, attach an image showing the scope settings. Attaching the
    Basic Stamp program you used would also help.

    The latest version of the Parallax scope code is 5.1.1.
    Is that what you are using?

    Also, please post a link to the earlier thread you mentioned.

    Phil,

    Understanding Signals only works with version 4 of the scope software. In the chapter they give the code and the scope settings.

    Here is a link to the book.

    Here is a link to the previous discussion.
