Re: video in/out on the BF533 EZKIT

Hello,

Can you give me file that does out put video?
Or tell me who config PII, DMA, SDRAM and do resets the ADV7171 device.

I have ADSP-BF533 EZLITE.
I do input frame video and put that in address: 0x01000.
I want to see that output in the monitor.

In the demo the file write in the Assembler.
I don't understand this file.

I work in the PAL video

Thanks,

Look to this function.
It creates a frame in memory. It is not the most eficient way to Output
video, but gives you insight of the topic.
After you have the frame just you set the DMA and PPI for output this
frame.
Good luck.

void create_frame(void){

blanking
