backpack overlay question

Phil, I have been modifying your backpack overlay software.
I am adding a wireless camera to my quadcopter and using a backpack to overlay onto the video stream. Since the camera is on a pan/tilt I connected the servos to the backpack and changed one of the commands to control the servos.
I noticed that several of the overlay files dont have your copyright or MIT statement. Are you ok with me modifying them and eventually releasing the changes?

    Go for it! Which files? I guess I need to add the MIT license boilerplate.

    I would suggest using the TV_overlay2 object. It allows user-defined characters and has all the necessary licensing boilerplate. It's attached.

    This code is Brilliant!, Unfortunately I'm not not the brightest bulb on the tree, And I'm struggling to make it work!
    '
    I think my wiring might be at fault.
    '
    I'm also confused with all the diffident PINs used?
    '
    Is there some ext. hardware needed for this code.
    '
    I did a search for over-laying video and this is what came up.

    Thanks in advance for any help or ideas!

    Several things
    1. The standard software in the backpack isn't overlay
    2. The overlay zip file on the parallax backpack page can be compiled and loaded using a prop plug (thats the way I do it)
    3. The overlay software must have a input video signal - the overlay will not display without an input video to overlay
    4. You must put the jumpers on the board to use overlay
    5. There is some demo software for a prop or a stamp that drives the backpack in overlay mode - its in the same overlay zip file. Try that out on a 2nd prop board before you start changing anything.

    The hardest thing I found was to get the basic system working
    plug a camera into a display
    get the cable for the backpack wired up correctly
    get the camers to the display via the backpack with the overlay software on it
    and then start programming

    Thanks for the reply

    I have ordered the backpack, I can't wait to get it.

    Of coarse I ordered a bunch of other stuff while I had the card out in the Parallax candy store.(My wife is gonna kill me when she See's this one)

    Thanks again for pointing me in the right direction! The back-pack is just what I was looking for.
