Configuring ADV7183A in BF533 EZ-LITE

Hi Friends,

I successfully run the example;

..\Blackfin\EZ-KITs\ADSP-BF533\Examples\Video Input\C

and captured the camera image.

Q1-) How can I configure ADV7183A to capture let say 360 pixels width
other than 720?

Example program captures the image only once.

Q2-) How can I configure ADV7183A to capture the image when
it is requested?

Sincerely,

Bilimsel

P.S: ADI recomended me to change the linelength from 720 to 360,
but it again captures 720 pixels in width! Start a New Thread

Hi,

Please see my answers.

Thanks,
Saravana.

By Changing the Manual Clock Control 1(sub address 28) register, You
can set the output frequency based on the captured Line Length. Please
refer the specifications of AD7183 for further clarifications.

Meanwhile, You have to change the PPI_COUNT, PPI_FRAME register
according to your line length.
You please go through the Hardware reference manual of BF533 for
more information.
Example program captures the image only once.
