Hi.

I'm trying to understand exactly what the following parameters mean:

HDSyncWidth

VDSyncWidth

Unfortuently it's not clear enough in driver user guide.

Did someone managed to work with aptina sensor MT9V024 properly? I don't really understand why but when working in raw data mode,I must configred the pitch to be twice the width otherwise I can't grab an image. Can someone tell me why?

 

Thank you,

Ronen

    Probably you meant HSyncWidth and VSyncwidth and not HDSyncWidth..

    Basically this refers to the width (time) that the VSync or HSync signals are ON. A reference to a Video timing diagram might help you here. Typically these are in terms of clocks ( for HSync) and lines (for vsync).

    Please refer to section 2.1.2 in the Video back end user guide. that might give you a clue.

    About the reason you configure pitch to be width*2, possibly the MT9V024 gives you each pixel which consumes 2 bytes each.

     

    Hope it helps.
