I'm trying to connect the CMUcam2 to the BS2 BOE. How do I do it? It appears there is no simple way (i know the boe-bot cmucam1 plugs directly into the AppMod input. If you could tell me how to connect them manually, or if there is a simple way i have overlooked. Any info would help, thank you.

    Your best bet would be to read the CMUcam2 manual to find out what lines need to be hooked up and what code needs to be communicated.

    I don't know if this will help, but the Parallax version is different from the CMU version... did you check out Parallax's version to see what differences there are and what changes you may need to make? http://www.parallax.com/Store/Microcontrollers/BASICStampModules/tabid/134/txtSearch/cmu/List/1/ProductID/29/Default.aspx?SortField=ProductName,ProductName

    p.s. - I wouln't call people "jerk"... you would be surprised how many questions have been answered just by telling folks to read the manual...

    Sgthos,

    From our Forum Guidelines (suggested reading)…

    5. Be polite. Flames, rude behavior, and personal insults are not helpful and will not be tolerated. Swearing is not allowed.

    What Franklin is trying to tell you is that the manual will specify the connection method, protocol, voltage specifications or other important information necessary to talk to the CMUCam. At the very least you should provide a link to the manual so others can look at it to see this information.

    Page 19 of the manual shows the serial connection from the CMUcam2 and page 4 of the boe manual shows the connection that can connect to that. What other questions do you have?

    A lot of people have had this same question over the past 2 years.
    According to a search over this time period, no one has found the answer.
    The CMUcam manual is available but there are no diagrams that
    include pinouts for the Parallax product. Parallax never released a
    Parallax specification sheet showing the pinouts. The CMUcam manual
    for download applies to other camera models - even the boards appear
    different. Plus, there are at least two versions of the parallax product.
    The software, written for Parallax, appears to access more ports
    than required by the camera board. There is clearly a pinout of the
    connector on BoeBot, however, not all those pins may be used by
    the CMUcam. There are several descriptions of which ports are used
    and their routing, however, these postings conflict with each other.
    I wrote to Parallax for the information and was told to write to the
    manufacturer of the CMUcam. I have written, and if they provide
    a pinout, it will be posted on the Parallax forum so everyone can
    benefit.

    Also, at the mentioned Parallax product site, this code is posted:

    Boe-Bot CMUcam Source Code 1 (.bs2)
    Boe-Bot CMUcam Source Code 2 (.bs2)
    Boe-Bot CMUcam Source Code 3 (.bs2)
    Boe-Bot CMUcam Source Code 4 (.bs2)
    Boe-Bot CMUcam Source Code 5 (.bs2)

    Has anyone had any luck in successfully running these on their
    Parallax BoeBot CMUcam?

    lod, what problems are you having? Have you tried hooking the cam to your computer and communicating that way? Let us know.
