Hi all, This may be an upcoming PIC project depending on it's feasabillity. I was wondering if a small BW video camera could be set up to monitor the position of a horizontally moving white vertical line against a dark background. I was hoping it may be a simple as using a comparator on the video signal to detect where the line is. Then I could use this signal to detect the current line position in relation to the frame width. Any thoughts? I've also finished a Parallax to PIC source code converter. This changes Parallax mnemonics to PIC mnemonics and leaves the labels and comments etc intact and will be available free on my web site - if and when the domain provider gets off thier backside and completes the transfer, (3 weeks now) >:-[ -- Best regards Tony http://www.picnpoke.com Email ???
