    Hi,

    I’m currently working with the Video Frame Capture-Example. Since I only need a frame of 60px * 60 px, I reduced my framesize to 80 * 60 (keeping the ratio of 4:3 – I do need that, don’t I?). But as soon as I do so, there’s no more output. I also tested 96 * 72 as well as a couple of other sizes (all smaller than 128×96). While tv.begin() always returns a 0, indicating that it worked as expected, the image isn’t updated.

    A second question: It should be possible to capture an image, call tv.end(), send that image with I²C and reactivate tv, shouldn’t it?

    Thanks in advance
    Sebastian

    The scanning code is only implemented for one resolution.

    For i2c communication, yes it might work better if you call tv.end() first. Just try it.

    OKay, thanks. I guess I’ll look into rewriting the scanning-function for a different resolution then.
