Other Parts Discussed in Thread: TMS320C6748

Hi,

I want to interface 2 Analog Composite cameras to TMDXLCDK6748 Development Board.

But the Board has only one Composite input port. Does any body have any idea , how to interface multiple cameras to the board.

Please Provide the scheme for interfacing 2 Analog Cameras without using any external Peripherals.

Thanks.

I am using CP-GAC-DC65L2H1 PAL camera with 650 TVL (720 X 480)resolution to run facedetect demo on LCDK6748 Board..

I have modified my code as described in this link

http://e2e.ti.com/support/embedded/starterware/f/790/p/223776/810098.aspx

Still I am not able to display captured image on VGA monitor.

I only get blank screen. Are there any other changes required in the code?

Please Help me to solve this problem.

Vivek Thaker,

Since your problem is not completely solved, I would recommend create new thread.
Personally, when I am looking for posts to read and help with, I ignore those that have been answered.
Others may do the same. Are you able to solve video capture issue as you mentioned last post.
If possible please provide a code snippet so that we can examine this issue.
