 Bigger Bigger  Smaller Smaller  Reset Reset

Hi,

I was wondering if anyone knows if it is possible for the arduino to read the vsync and hsync signals from a composite video signal. I don't need any of the picture information, I just need to know the line & column numbers if what's being sent to the TV, and I figured that if I could read the sync signals I could calculate the position. Could the arduino handle this, or am I barking up the wrong tree.

I don't think you connected the grounds, Dave.

Try an LM1881 sync splitter - makes things a bit easier.
