Hi ,

 

We are working on ADV7180 evaluation board EVAL-ADV7180-32EBZ .

We are facing some issues regarding video display on LCD.

 

Our Harware setup is: 

 

  1. ADV7180-EVAL & STM32F769i-Eval board are used for this testing and both are powered up.
  2. USB cable from PC to the mini usb connected to ADV7180 Evaluation board.
  3. DVD player CVBS output connected to ADV7180-EVAL CVBS input.
  1. ADV7180- EVAL 8 Bit data, HSYNC, YSYNC, LLC and GND is connected to STM32F769i-Eval board (8 Bit camera interface).

 

 

Software Application programming on PC:

 

  1. Run ADV Register Control 7.0
  2. Selected the ADV7180_ADV7180@_ADV7391-VER.1.1LFCSP32.txt script. and Click “OK”
  3. Selected the “CVBS AutoDetect” Script from the  Setting->Scripts->CVBS Fast Switch->PAL-M In, Fast Switching.

 

As of now, Our current resolution is 640*480.We are not getting a clear picture on LCD. getting a slant frames from the video.

Attached are the images for your reference.

 

Could anyone please suggest the settings for PAL and NTSC , so that it gives solution to our problem?

 

Thanks and Regards
